Server memory hp. RAM. Principles of memory expansion in Lockstep mode
RAM plays a significant role in server productivity, so the selection of memory modules will require a careful approach when choosing the configuration of the server system. HP RAM meets all current technology standards and is designed to provide high data processing speed for high-volume applications.
Current types of operative memory
- DDR2. This standard is used mainly in desktop desktop computers and budget servers on the Internet. Prote DDR2 memory demonstrates twice the performance of previous generations of DDR due to the increased clock frequency. Besides, I remember the lowest level of energy and good cooling;
- DDR3. The new DDR3 standard has replaced DDR2 in high-class solutions. This type of memory has the latest data processing algorithms, which gives a significant increase in productivity. The energy consumption of DDR3 modules is 30% lower than that of DDR2, and the throughput of the device becomes 21300 MB/sec. It is significant that DDR3 memory is wrapped in tandem with DDR2 modules, but not by chance.
This time we are talking about HP products. All these problems were solved by our engineers, and there are only a few surprises that servers from your vendor can produce. However, if you are independently engaged in server maintenance, then perhaps our information may be of use to you.
RAM
When upgrading HP servers (not just that), problems often arise with the selection of RAM. As practice shows, system administrators and engineers are not always aware of this nutrition. If you install memory modules behind these, then, most likely, the server simply will not start. If the RAM configuration is incorrect, there is a better option: the machine is running, but not at maximum productivity.For multi-processor HP servers, it is usually necessary to use only register memory with the function of correction of errors (ECC RDIMM), and for single-processor ones - unbuffered memory with ECC (UDIMM). I would like to confirm that UDIMMs can be installed in multi-processor servers, but this is not possible for several reasons:
- I will oblige the memory. As a rule, it is 24-32 GB per CPU.
- UDIMM strips, as a rule, are to blame for being “original” HP ones, otherwise they may cause fleeting server reboots. This phenomenon is recorded primarily on three models: DL380p Gen8, DL360e Gen8, ML310e Gen8v2. At the same time, you can install RDIMM memory from any vendor without any problems.
The advantage of UDIMM memory is that it works much faster than RDIMM, in the presence of a buffer operation delay. However, with the correct memory configuration in multi-channel RDIMM systems, unbuffered memory can be outperformed. It is not possible to install RDIMM and UDIMM modules overnight.
You can change UDIMM memory from RDIMM behind the sticker. For example, it says 12800 R, then the register memory is 12800 E, Unbuffered with ECC.
When installing an RDIMM, ensure that only one memory is used (1rx4, 2rx4). Managed by IBM (Lenovo), HP servers are sensitive to memory configuration. When installing modules, it is recommended to distribute memory evenly between server processors and between channels. Otherwise, the server may simply not connect, or its productivity will be reduced. The voltage of the strips on HP servers is not important, but still be sure to install new strips according to the voltage.
Information about the optimal placement of RAM in DIMM slots is always under the server cover and in the official manual.
Whenever you need to talk about upgrading or repairing servers, you always have to worry about the component manufacturer. Although the company only uses original components, without wasting money, it selects excellent components from third-party manufacturers. We appreciate that there is a need for faith here:
- Level of capacity of third-party components.
- The difference in the Vartosti is equal to the original ones.
- Information about the reliability of third-party components.
- The level and permissibility of risks when using third-party components.

When choosing new storage devices for the server, it is more important to be careful when changing the memory configuration. But still, there is a pitfall here and, in part, myths.The main idea is that for HP servers it is necessary to purchase accumulators including the same manufacturer. Let us know that all devices with the HP logo run proprietary firmware. This type of “real” discs has a lot more roads. And, frankly speaking, it is doubtful that we are satisfied with overpaying 2-2.5 times. However, the Hewlett-Packard corporation itself does not generate storage; it purchases them from other vendors. And as evidence shows, most models of HP servers can be used with products from HGST, Toshiba, Seagate, and Western Digital.
When choosing storage devices, check which storage devices are supported by the Raid controller of your server. Some controllers do not support SAS storage devices, and may also not support storage devices with a volume larger than 2-3 TB.
If the server does not accept third-party storage devices when connected, this is most often due to a malfunction of the storage device itself or the Raid controller. One more important detail: at all times, do not install disks for desktop systems in the enterprise server. Judging from our knowledge, you can see a number of the most popular models of non-ready disks that can be used without problems on servers from G7 to Gen9:
- Seagate Savvio (SAS)
- Seagate Constellation (SATA/SAS)
- Seagate Enterprise Capacity (SATA/SAS)
- Seagate Enterprise Performance (SATA)
- WD VelociRaptor (SATA)
Processors
When replacing processors, it is more important to check in the server specifications what processor model is supported. When doing this, do not forget to maintain the TDP heatsink and the CPU itself. Most often this helps to eliminate possible problems.However, with the increased number of processors, it is impossible every time to install coolers on the skins of them, relying on the air conditioning of the server area. The skin fan cools the air zones on the motherboard. Without regular cooling, there is a significant risk of time-to-hour overheating of processors and RAM, even before the server exits due to melting or burning of electronic components.
After installing two processors on the server that are an order of magnitude stronger for one drain, it may not turn on. For example, our case ended up with an HP ML350p Gen8 server. The reason is that some models on the motherboard have a fault that blocks the power supply when the voltage exceeds a certain base threshold. If this blocking is necessary, then the only option is to replace the motherboard. If the server is not under warranty, it can cost you a fortune, since HP is famous for its low prices for its hardware.
Protein is a technique for bypassing this defense. It is possible that instead of one or two cob processors E5-2609 (v1/v2/v3), you need to install two productive E5-2690 (v1/v2/v3). To avoid problems when upgrading, do it this way:
- Update all software to the latest versions (iLO, BIOS, AHS, etc.)
- Please wait until the server is reinitialized with E5-2609 installed.
- Install two processors of the “intermediate” level, for example, E5-2640. Wait for the POST verification to be completed.
- And then install the E5-2690 tanks.
Intelligent Provisioning and Server Upgrades
HP ProLiant Gen8 and Gen9 servers have a powerful Intelligent Provisioning tool that allows you to configure the server, update the firmware of certain components, and monitor harmful parts of the machine. Sometimes, when you try to update, you see a warning about the impossibility of connecting to the HP database. The reason lies in the outdated version of Intelligent Provisioning. You can update it like this:- For Gen8, download the Intelligent Provisioning recovery media image version 1.62b, and Gen9 - the latest version.
- Mount the image using iLO or burn it to CD/DVD. Do not write the image to a flash drive; Intelligent Provisioning will not update from it when you launch it.
- When the server is up and running, select the One Time Boot to CD-ROM option.
- If the server wants a disk (or image), then from the Gen9 menu select the Interactive HP Intelligent Provisioning Recovery Media option. On the Gen8 server, updates will occur automatically.
- On the next screen, press the Reinstall Intelligent Provisioning button, check for completion and restart normally (only for Gen9).
There are two options for completely upgrading the server.
- Manually download and install all the necessary drivers and firmware for your server model. This option is simple, since there is only one server and also the OS.
- If your servers are running Windows, it is best to use the Service Pack for ProLiant (SPP) service pack.
- It is necessary to capture the service pack image.
- Install HP USB Key Utility for Windows.
- With additional programs, an image of the service pack is burned on a flash drive with a capacity of at least 8 GB.
- We secure the server from a flash drive. It is recommended to select Interactive Firmware Update, so you can control the update process.
- After selecting the client, select Update Firmware. Once the property is verified, the system populates the list of updates that will be installed after pressing the Deploy button.
- After completing the update, you need to re-enable. The server will shut down and shut down once, installing firmware, after which it will be properly installed.
Adapters are not marked
If you update the Emulex drivers for tether adapters from version 3.x.x to 10.x.x, then if the tether adapters are reinstalled, they may no longer appear. To avoid this problem, it is recommended to install Emulex 4.x.x from the beginning, and then the latest version. You can get rid of this problem another way: first upgrade to the OneConnect image, and then upgrade to the Service Pack for ProLiant. And since the adapters are no longer displayed, you just need to update with the OneConnect image."Speciality" of HP DL360p Gen8 servers
Initially, the model of this series was equipped with E5-26xx processors of the first revision, and in 2013 Intel released another iteration - V2. Vendors, including HP, began to buy new lines. Dell and IBM did not begin to change the database, but motherboards began to have a different part number. But we took a different route to HP. As a result, there are two HP DL360p models on the market, which do not differ in any way, except for the problem of mounting radiators. In the first version the fastening is more important, in the other it is screw.Essentially, it's rubbish. However, you can bring up additional costs. If you plan to install another processor, be sure to check the revision of your server (by serial number, or by looking under the cover).
The part number of the old important radiator is 654770-B21.
The part number of the new quint radiator is 712731-B21.
Lack of life blocks
Dealers of HP servers with x4-backplanes of backup power supply (RPS), for example, ML350 Gen9, wonder why to start the machine it is necessary to connect at least three life blocks, whose total power outweighs the maximum utilization of the server.On the right, up to 9 PCI-E cards and up to 6 HDD backplanes can be installed in the ML350 Gen9 (or, for example, an internal streamer + 5 HDD backplanes). But you can still live even richly. RPS backplanes allow you to ensure the over-the-air server storage with a sharp increase in demand, as well as accumulated energy. The connection of life blocks to the backplane follows the N-1 scheme, where N is the number of connectors. If you need the server to live over-the-air, then the life blocks must be connected to all connections in the backplane. Since there is no need for overworld storage, then to start a server with x4-backplay you need three blocks of life, and with x2-backplay - one block.
Programming control via IPMI
IPMI can be used for remote networking by servers. Possible situations when it is not possible to establish a connection with the IPMI server service:Ipmitool -I lanplus -H $ip -U $user -P $pass
Error: Disabled before installing IPMI v2 / RMCP+ session
There could be two reasons:
This problem occurs rarely and occurs in chaotic, independent server restarts. There are no errors in the OS logs, and the iLO logs also contain nothing critical. In such situations, updating the software, replacing power cables, or replacing power supply cables does not help. The problem appears to be a change in the settings for managing the life of the server BIOS. Briefly, all mechanisms for reducing the processor clock frequency are turned on:- Power Management Options -> HP Power Profile -> Maximum Performance
- Power Management Options -> HP Power Regulator -> HP Static High Performance Mode
- Power Management Options -> Advanced Power Management Options -> Collaborative Power Control -> Disabled
- Power Management Options -> Advanced Power Management Options -> Minimum Processor Idle Power Core State -> No C-States
- Power Management Options -> Advanced Power Management Options -> Minimum Processor Idle Power Package State -> No Package State
Crash after server crash
We've had a lot of troubles when the lights are on when the server is turned on and there is no video signal. The machine does not ping, iLO does not respond, although the LEDs indicate iLO and Ethernet activity. The keyboard and Misha don’t work. Most often, this happened after a regular server shutdown, without manipulation, without interruptions. A similar problem occurred on servers from Gen5 to Gen8.The exact nature of this problem and its causes have not yet been revealed. In one phase, it was possible to switch all the System Maintenance Switch switches to the ON position, and after about an hour back to OFF. It seems that the server came back to life after the memory modules were swapped. Unfortunately, in many cases it was not possible to update the servers.
Loud noise from the refrigeration system
This problem was most common in ML350e Gen8 servers. Immediately after the server is warmed up, the fans go to high speed. The fluidity of the wrapper does not decrease due to any modification. As a result, a constant and high level of noise is created.In a number of cases, the problem occurred with various PCI-E expansion cards: edgebands and USB hubs. However, this problem was even worse on servers without expansion cards installed. Several times it was necessary to dismantle and reinstall all fans and their fans, with reconnections of the life wires. Once the fans turned to normal speed after updating the firmware and disabling iLO. It also happened that in the BIOS the cooling control settings were changed, and it turned out to be enough to change the value from Increased to Optimal Cooling.
Reset configurations on Gen8 servers
Finally, we would like to inform you not about the repair, but about a feature of HP servers of the Gen8 and Gen9 generations: on motherboards there are daily primary jumpers with a different configuration. If you need to quickly collect money, then you can earn it like this:
Installing another raid controller on Gen8 and Gen9 servers
If another raid controller is installed (for example, one raid is under the system, the other is under the data), the server may freeze at the OS stage or fail to pass POST. Most often this is achieved through the wrong boot code.To solve this problem, you need to create the following configuration:
- Raid 1 (for example, starting a P420i).
- Raid2 (software or embedded raid, for example, B120i, P222i).
- Raid3 (hardware P420).
Advantages of HP servers
It would be unfair to talk too much about the problems of HP servers, and it is not without reason that the products of its manufacturer are highly popular. Servers of the Proliant series are respected among the best in their class, and are certainly remembered for their reliability, low iLO and well-protected price. HP itself often sets the bar for the functionality and versatility of servers, using non-standard, but effective engineering solutions.The axis is as small as possible for HP servers:
- Availability of proprietary features: iLO, Intelligent provisioning, Active Health System.
- There is a line of budget and high-productivity models.
- The nomenclature of the entry has been limited (although for some it is not long) for the skin model, which allows for the elimination of irrational costs during a future upgrade.
- Advanced technical support.
- One of the shortest implementations of the updated PZ.
- Gen8 and Gen9 - the best implementation of diagnostic values on sleds under HDD.

Memory options
IMPORTANT: This server does not directly support LRDIMMs, RDIMMs, UDIMMs or HDIMMs.
Trying to mix any combination of these DIMMs may cause the server system to delay BIOS initialization. The memory subsystem on your server can support LRDIMMs, RDIMMs, UDIMMs or HDIMMs:
- UDIMMs represent the main types of memory modules and offer lower latency per DIMM per channel configuration and (obviously) low power consumption, or interconnection pressure.
- RDIMMs are larger than UDIMMs and include address parity protection.
- LRDIMMs support higher density, lower single-channel and dual-channel RDIMMs and higher fluidity, lower multi-channel RDIMMs. This support potentially allows for higher DIMM density to be installed, resulting in increased system capacity and high throughput.
- HDIMMs provide higher fluidity than lower DIMMs. 12 DIMMs are required per processor with HDIMMs.
All types are called DIMMs if the information is shared across all types. When specifying LRDIMM, RDIMM, UDIMM, or HDIMM, the information is reported to this type. All memories installed on the server are of the same type. The server supports the latest DIMM flexibility:
- Single- and dual-rank PC3-10600 (DDR3-1333) RDIMMs offer speeds up to 1333 MT/s
- Single- and dual-rank PC3-12800 (DDR3-1600) RDIMMs offer speeds up to 1600 MT/s
- Single- and dual-rank PC3-14900 (DDR3-1866) RDIMMs offer speeds up to 1866 MT/s
- Single- and dual-rank PC3-10600 (DDR3-1333) UDIMMs offer speeds up to 1333 MT/s
- Quad-rank PC3L-10600 (DDR3-1333) LRDIMMs, operating as dual-channel DIMMs, up to 1333 MT/s
- Quad-rank PC3L-14900 (DDR3-1866) LRDIMMs perform like dual-channel DIMMs up to 1866 MT/s.
For further information about memory configuration, see the short specification in the HP bulletin on the website (http://www.hp.com/go/productbulletin).
HP SmartMemory
HP SmartMemory, introduced for Gen8 servers, authenticates and opens capability songs available only to HP qualified memory and verifies that memory has been installed that has passed the qualification process ii and HP testing. Performance-qualified memory, tuned for HP ProLiant and BladeSystem servers, is trending toward HP's upcoming expanded support through HP Active Health and advanced software. Several productivity features are unique to HP SmartMemory. HP SmartMemory 1.35 DDR3-1333 memory is fragmented to achieve the same level of productivity as 1.5 Memory. For example, while the industry supports DDR3-1333 RDIMM at 1.5 V, this Gen8 server supports DDR3-1333 RDIMM up to 3 DIMMs per channel 1066 MT/s and operates at 1.35 V. This, obviously, with getting along up to 20% less energy on par with DIMMs without performance penalty. In addition, the galuz supports UDIMMs with 2 DIMMs per channel of 1066 MT/s. HP SmartMemory supports 2 DIMMs per channel with a speed of 1333 MT/s, or 25% more throughput.
Memory subsystem architecture
The memory subsystem on this server is divided into channels. The processor skin supports up to four channels, and the skin channel supports three DIMM slots, as shown in the table.
The expansion of serial numbers can be seen in the “DIMM Slot Location” section. This multi-channel architecture ensures increased productivity in advanced ECC mode. This architecture also includes Lockstep and Online Spare Memory. The DIMM on your server is identified by a number and letters. Letters indicate the order of retouching. The slot numbers indicate the ID of the DIMM slot to be replaced.
Single-, double-channel DIMMs
To understand and configure memory protection modes correctly, it is necessary to carefully work with one- or two-channel DIMMs. Actions before configuring DIMMs are based on these classifications. A single-channel DIMM contains one set of memory chips, which can be accessed when writing or reading from memory. A dual-channel DIMM is similar to two single-channel DIMMs, only with one rank and access to the same module at the same time. A four-channel DIMM is essentially two dual-channel DIMMs on the same module. Only one rhubarb available overnight. The server's memory management subsystem selects the appropriate rank for the DIMM memory at the time of writing or reading from the DIMM memory. Two-channel DIMMs provide the greatest performance with the latest memory technologies. For example, while threaded DRAM technology supports up to 8 GB of single-channel DIMMs, for dual-channel DIMMs 16 GB and four-channel DIMMs would be 32 GB. LRDIMMs are designated as multi-channel DIMMs, rather than functioning more like dual-channel DIMMs. It is clear that the rows of DRAM memory modules are DIMMs, but the LRDIMM buffer creates an abstraction that allows the DIMM to appear as a dual-channel DIMM in the system. With LRDIMM, the buffer also isolates electrical input from DRAM from the system, which allows for faster operation. These two changes allow the system to support up to three LRDIMMs per memory channel, providing 50% more memory capacity and higher RAM speed compared to four-channel RDIMMs .
DIMM identification
To check the characteristics of the DIMM, check out the labels attached to the DIMM, as well as the little ones in the table below.
To extract information about the remaining memory of the divas. QuickSpecs on the HP website (http://h18000.www1.hp.com/products/quickspecs/ProductBulletin.html). On the site, select a geographic region and find a product by name or product category.
Memory configurations
To optimize server availability, the server supports the latest AMP modes:
- ECC extensions - provide up to 4-bit error correction and increased productivity in Lockstep mode.
This mode is victorious for promotions for this server.
- Online spare memory – provides protection against damaged or degraded DIMMs. The memory is configured as spare, and the memory is automatically re-microfied when the system detects that a DIMM is plugged. This allows you to take that DIMM out of operation, which has a higher probability of removing non-overloading (which would lead, as a result, to system downtime).
Parameters for detailed memory protection can be adjusted at RBSU. Since powering AMP mode is not supported by the installed DIMM configuration, the server is forced into Advanced ECC mode. For additional information, see the HP ROM-Based Setup Utility section. The server can also operate in a single channel mode or a combined channel mode (lockstep). When you start the lockstep mode, you remove security in one of two ways:
- When operating with UDIMM (options with x8 DRAM devices), the system cannot fully cope with DRAM failure (SDDC). In the independent mode, the channel will be reduced to a non-overflow.
- When running with RDIMM (required with x4 DRAM devices), the system can survive double DRAM device failure (DDDC). When running offline, the server may only see one DRAM device (SDDC) fail.

Expanded ECC memory configuration
ECC memory has been expanded - this is a mode for protecting the memory of this server. The ECC standard can correct single-bit memory cuts and expose multi-bit memory cuts. When multi-bit forks are detected beyond standard ECC, a server fork is signaled and the server is down. Extended ECC protects the server from various multi-bit memory bypasses. Extended ECC can handle single-bit and 4-bit memory bypasses, since not all bits reside on a single DRAM device on a DIMM. Extended ECC provides additional protection compared to standard ECC, allowing it to correct memory errors that otherwise would not be corrected and would result in crashes on the server. Using advanced memory fault detection technology, the HP Advanced server provides notification when a DIMM is degraded, and there is a high rate of faulty memory faults.
Configuration Online Spare memory
Online memory backup provides protection against degraded DIMMs, reducing the risk of uncorrected memory degradation. This protection is provided without any support from the operating system. Online spare memory protection sees one rank for the cutaneous memory channel for vikorstan as a spare memory. Series solutions available for the OS and add-ons. Since the correction of memory damage occurs at an ever-increasing pace, even more so on any spare rows, the server automatically copies spare rows instead of the degraded memory. Then the server detects the faulty memory level and automatically switches to the online spare.
Lockstep memory configuration
The Lockstep mode will ensure the protection of high-volume memory data stored on the same DRAM device. The Lockstep mode can be corrected if I solve the problem of DRAM and install it on x4 and x8 DIMM types. DIMM modules in the skin channel are responsible for the same HP lot numbers.
General principles for replenishing DIMM slots
- install DIMM modules only if a supporting processor is installed;
- when installing two processors, balance the DIMMs across the two processors;
- The other DIMM slots indicate the first slot of the channel (Ch 1-A, Ch 2-B, Ch 3-C, Ch 4-D);
- do not mix LRDIMMs with UDIMMs, RDIMMs or HDIMMs;
- do not install more than two UDIMMs per channel;
- UDIMM modules should not be installed in slots Ch 1-I, Ch 2-J, Ch 3-K or Ch 4-L;
- HDIMM requires 12 DIMMs per processor;
- When installing two processors, install DIMMs in alphabetical order to balance between the two processors: P1-A, P2-A, P1-B, P2-B, P1-C, P2-C and so on.
For detailed information about rules and recommendations for memory configuration, you can access the Online DDR3 Memory Configuration Tool on the HP website (http://www.hp.com/go/ddr3memory-configurator). The fluidity of the DIMM is shown in the following table.
Basic principles for hosting an Extended ECC
For configuration in Advanced ECC mode, follow these rules:
- You can install DIMMs individually.
Restoration of memory Online spare
To configure in Online Spare Memory mode, follow these rules:
- Follow the basic principles in the area of DIMM placement in slots;
- the skin canal is to blame for the maternal configuration of Online Spare;
- the skin canal can change the operational configuration of the spare online;
- The skin filling channel is to blame for the reserve channel.
a) single dual-channel DIMM is an unacceptable configuration; b) LRDIMMs are considered to be dual-channel DIMMs.
Principles of memory expansion in Lockstep mode
For Lockstep memory configuration mode, follow these recommendations:
- Follow the basic principles in the area of DIMM placement in slots;
- DIMMs adjust all channels, the processors are at fault however;
- In multi-processor configurations, the processor is to blame due to the same Lockstep memory configuration;
- On multi-processor configurations, the processor may have different permissible Lockstep memory configurations.
The procedure for roztashuvannya
For a memory configuration with one or more processors, place the DIMM slots in the following order:
- LRDIMM: sequentially in alphabetical order (from A to L);
- RDIMM: sequentially in alphabetical order (from A to L);
- UDIMM: from A to H, sequentially in alphabetical order, do not place DIMM slots I through L;
- HDIMM: all 12 DIMM modules per processor are full.
After installing DIMM modules, use RBSU to configure Advanced ECC, Online spare, or Lockstep.
Installing DIMMs
The server supports up to 24 DIMMs. To install memory DIMMs:
1. open the server;
2. add life:
a) insert the leather life cord through the life cord;
b) disconnect the power cord from the server;
3. hang the server from the rack;
4. remove the access panel;
5. remove the wind deflector;
6. Unlock the DIMM slots;
7. Install the DIMM module.
8. install the access panel;
9. install the server on the rack;
10. connect the skin cable to the server;
11. connect the skin life cable to the life line;
12. Shut down the server.
Use RBSU (HP ROM-Based Setup Utility) to configure the robot mode with memory.

Most often this helps to eliminate possible problems.However, with the increased number of processors, it is impossible every time to install coolers on the skins of them, relying on the air conditioning of the server area. The skin fan cools the air zones on the motherboard. Without regular cooling, there is a significant risk of time-to-hour overheating of processors and RAM, even before the server exits due to melting or burning of electronic components.
After installing two processors on the server that are an order of magnitude stronger for one drain, it may not turn on. For example, our case ended up with an HP ML350p Gen8 server. The reason is that some models on the motherboard have a fault that blocks the power supply when the voltage exceeds a certain base threshold. If this blocking is necessary, then the only option is to replace the motherboard. If the server is not under warranty, it can cost you a fortune, since HP is famous for its low prices for its hardware.
Protein is a technique for bypassing this defense. It is possible that instead of one or two cob processors E5-2609 (v1/v2/v3), you need to install two productive E5-2690 (v1/v2/v3). To avoid problems when upgrading, do it this way:
- Update all software to the latest versions (iLO, BIOS, AHS, etc.)
- Please wait until the server is reinitialized with E5-2609 installed.
- Install two processors of the “intermediate” level, for example, E5-2640. Wait for the POST verification to be completed.
- And then install the E5-2690 tanks.
Intelligent Provisioning and Server Upgrades
HP ProLiant Gen8 and Gen9 servers have a powerful Intelligent Provisioning tool that allows you to configure the server, update the firmware of certain components, and monitor harmful parts of the machine. Sometimes, when you try to update, you see a warning about the impossibility of connecting to the HP database. The reason lies in the outdated version of Intelligent Provisioning. You can update it like this:- For Gen8, download the Intelligent Provisioning recovery media image version 1.62b, and Gen9 - the latest version.
- Mount the image using iLO or burn it to CD/DVD. Do not write the image to a flash drive; Intelligent Provisioning will not update from it when you launch it.
- When the server is up and running, select the One Time Boot to CD-ROM option.
- If the server wants a disk (or image), then from the Gen9 menu select the Interactive HP Intelligent Provisioning Recovery Media option. On the Gen8 server, updates will occur automatically.
- On the next screen, press the Reinstall Intelligent Provisioning button, check for completion and restart normally (only for Gen9).
There are two options for completely upgrading the server.
- Manually download and install all the necessary drivers and firmware for your server model. This option is simple, since there is only one server and also the OS.
- If your servers are running Windows, it is best to use the Service Pack for ProLiant (SPP) service pack.
- It is necessary to capture the service pack image.
- Install HP USB Key Utility for Windows.
- With additional programs, an image of the service pack is burned on a flash drive with a capacity of at least 8 GB.
- We secure the server from a flash drive. It is recommended to select Interactive Firmware Update, so you can control the update process.
- After selecting the client, select Update Firmware. Once the property is verified, the system populates the list of updates that will be installed after pressing the Deploy button.
- After completing the update, you need to re-enable. The server will shut down and shut down once, installing firmware, after which it will be properly installed.
Adapters are not marked
If you update the Emulex drivers for tether adapters from version 3.x.x to 10.x.x, then if the tether adapters are reinstalled, they may no longer appear. To avoid this problem, it is recommended to install Emulex 4.x.x from the beginning, and then the latest version. You can get rid of this problem another way: first upgrade to the OneConnect image, and then upgrade to the Service Pack for ProLiant. And since the adapters are no longer displayed, you just need to update with the OneConnect image."Speciality" of HP DL360p Gen8 servers
Initially, the model of this series was equipped with E5-26xx processors of the first revision, and in 2013 Intel released another iteration - V2. Vendors, including HP, began to buy new lines. Dell and IBM did not begin to change the database, but motherboards began to have a different part number. But we took a different route to HP. As a result, there are two HP DL360p models on the market, which do not differ in any way, except for the problem of mounting radiators. In the first version the fastening is more important, in the other it is screw.Essentially, it's rubbish. However, you can bring up additional costs. If you plan to install another processor, be sure to check the revision of your server (by serial number, or by looking under the cover).
The part number of the old important radiator is 654770-B21.
The part number of the new quint radiator is 712731-B21.
Lack of life blocks
Dealers of HP servers with x4-backplanes of backup power supply (RPS), for example, ML350 Gen9, wonder why to start the machine it is necessary to connect at least three life blocks, whose total power outweighs the maximum utilization of the server.On the right, up to 9 PCI-E cards and up to 6 HDD backplanes can be installed in the ML350 Gen9 (or, for example, an internal streamer + 5 HDD backplanes). But you can still live even richly. RPS backplanes allow you to ensure the over-the-air server storage with a sharp increase in demand, as well as accumulated energy. The connection of life blocks to the backplane follows the N-1 scheme, where N is the number of connectors. If you need the server to live over-the-air, then the life blocks must be connected to all connections in the backplane. Since there is no need for overworld storage, then to start a server with x4-backplay you need three blocks of life, and with x2-backplay - one block.
Programming control via IPMI
IPMI can be used for remote networking by servers. Possible situations when it is not possible to establish a connection with the IPMI server service:Ipmitool -I lanplus -H $ip -U $user -P $pass
Error: Disabled before installing IPMI v2 / RMCP+ session
There could be two reasons:
This problem occurs rarely and occurs in chaotic, independent server restarts. There are no errors in the OS logs, and the iLO logs also contain nothing critical. In such situations, updating the software, replacing power cables, or replacing power supply cables does not help. The problem appears to be a change in the settings for managing the life of the server BIOS. Briefly, all mechanisms for reducing the processor clock frequency are turned on:- Power Management Options -> HP Power Profile -> Maximum Performance
- Power Management Options -> HP Power Regulator -> HP Static High Performance Mode
- Power Management Options -> Advanced Power Management Options -> Collaborative Power Control -> Disabled
- Power Management Options -> Advanced Power Management Options -> Minimum Processor Idle Power Core State -> No C-States
- Power Management Options -> Advanced Power Management Options -> Minimum Processor Idle Power Package State -> No Package State
Crash after server crash
We've had a lot of troubles when the lights are on when the server is turned on and there is no video signal. The machine does not ping, iLO does not respond, although the LEDs indicate iLO and Ethernet activity. The keyboard and Misha don’t work. Most often, this happened after a regular server shutdown, without manipulation, without interruptions. A similar problem occurred on servers from Gen5 to Gen8.The exact nature of this problem and its causes have not yet been revealed. In one phase, it was possible to switch all the System Maintenance Switch switches to the ON position, and after about an hour back to OFF. It seems that the server came back to life after the memory modules were swapped. Unfortunately, in many cases it was not possible to update the servers.
Loud noise from the refrigeration system
This problem was most common in ML350e Gen8 servers. Immediately after the server is warmed up, the fans go to high speed. The fluidity of the wrapper does not decrease due to any modification. As a result, a constant and high level of noise is created.In a number of cases, the problem occurred with various PCI-E expansion cards: edgebands and USB hubs. However, this problem was even worse on servers without expansion cards installed. Several times it was necessary to dismantle and reinstall all fans and their fans, with reconnections of the life wires. Once the fans turned to normal speed after updating the firmware and disabling iLO. It also happened that in the BIOS the cooling control settings were changed, and it turned out to be enough to change the value from Increased to Optimal Cooling.
Reset configurations on Gen8 servers
Finally, we would like to inform you not about the repair, but about a feature of HP servers of the Gen8 and Gen9 generations: on motherboards there are daily primary jumpers with a different configuration. If you need to quickly collect money, then you can earn it like this:
Installing another raid controller on Gen8 and Gen9 servers
If another raid controller is installed (for example, one raid is under the system, the other is under the data), the server may freeze at the OS stage or fail to pass POST. Most often this is achieved through the wrong boot code.To solve this problem, you need to create the following configuration:
- Raid 1 (for example, starting a P420i).
- Raid2 (software or embedded raid, for example, B120i, P222i).
- Raid3 (hardware P420).
Advantages of HP servers
It would be unfair to talk too much about the problems of HP servers, and it is not without reason that the products of its manufacturer are highly popular. Servers of the Proliant series are respected among the best in their class, and are certainly remembered for their reliability, low iLO and well-protected price. HP itself often sets the bar for the functionality and versatility of servers, using non-standard, but effective engineering solutions.The axis is as small as possible for HP servers:
- Availability of proprietary features: iLO, Intelligent provisioning, Active Health System.
- There is a line of budget and high-productivity models.
- The nomenclature of the entry has been limited (although for some it is not long) for the skin model, which allows for the elimination of irrational costs during a future upgrade.
- Advanced technical support.
- One of the shortest implementations of the updated PZ.
- Gen8 and Gen9 - the best implementation of diagnostic values on sleds under HDD.

Resolving problems after installing new memory
If the computer does not start or Windows does not open after adding memory, sound signals are heard or indicators blink when using the keys. Caps Lock or else Num Lock, try the following activities:
Remove and reinsert the new memory module.
Remove the new memory module and clean the slot at the socket before it is installed. Blow through the compressed air through a thin nozzle, vikorist and dry eyepieces, for sawing or washing.
Remove a new memory module and try starting the computer again. As soon as the computer starts, check the correct type and capacity of the attached memory module.

SO-DIMM memory modules and options
U laptops Small memory modules from large-scale memory modules (SO-DIMM) are used. Smaller and thinner DIMMs are therefore used if they are located behind the chassis. SO-DIMM modules for HP computers are responsible for such problems
The number of contacts on the SO-DIMM module depends on the type of connector.
A 200-pin connector is required to install SO-DIMM modules.
DDR2 SO-DIMM is incompatible with DDR1 DIMM and DDR2 DIMM memory modules.
DDR3 SO-DIMMs are not compatible with DDR1 or DDR2 modules and require a 204-pin connector for installation.
If your computer is running 533 MHz or 667 MHz, use PC2-4200 memory (DDR2 DIMM 533 module).
Memory modules DIMMs and options
Memory modules with large DIMMs and small secondary boards that house groups of memory chips. The stinks are vikorist at most desktop computers. DIMMs have a larger connection path with two rows of contacts on the skin side, which ensures faster data transfer when compared to modules with single row memory chips (SIMMs). DIMMs can be manufactured in single-sided or double-sided format. DIMMs cannot be added in pairs and must be combined with other DIMMs with the same number of pins. For example, a 1 GB DIMM can be installed on the motherboard in addition to a 2 GB DIMM.
Note.The speed of operation of DIMM modules cannot be affected by the frequency of the system bus. If a number of DIMM modules with different operating frequencies are installed, then the operating frequency of all installed memory is the same as the operating frequency of the DIMM module with the lowest speed.
HP computer DIMMs are responsible for this behavior
The number of contacts on a DIMM module depends on the type of connector.
For memory DDR Requires a 184-pin connector and an operating voltage of 2.5 Art.
Memory DDR2 It is incompatible with DDR1 memory, and it requires a 240-pin connector, as well as an operating voltage of 1.8 st.
Memory DDR3 will provide about twice the throughput of DDR2.
Modules DDR3 It's crazy with DDR1 or DDR2.
To install modules DDR3 The DIMM will require a 240-pin connector and an operating voltage of 1.5 V. The connector for DDR3 memory is wired differently than for DDR2 or DAR. Do not hesitate to install a DDR3 module on a motherboard designed for DAR or DDR2. Otherwise, the motherboard and DIMMs may be permanently damaged.
SCRAM (synchronous dynamic memory with sufficient access): Choose SCRAM memory type DAR, if the computer comes with DDR-SDRAM modules.
RIMM memory modules and applications
DDR3 memory supports 3 DIMMs in tri-channel mode. The same size and type of memory must be installed in the corresponding DIMM sockets for channels A, B, and C. Typically, memory slots are color coded to make them easier to understand.
Memory addition for modernization
HP recommends that you purchase memory modules directly from an HP retailer, an authorized HP dealer, or from a trusted computer parts supplier such as Crucial .
Many computer components suppliers and HP partners can help you select the right memory for your computer model. Before adding memory modules, you need to know what kind of memory is needed and what type is suitable for your computer.
