Creating a raid array windows 10. What is a RAID array? We connect and configure
Raid array is a mirror image of data that is stored on a user's computer device on several hard drives. When one drive becomes unusable, you can easily replace it with another one without losing your personal files.
In order to install the operating system Windows 7, 8.1 or 10, it is not enough just to purchase two hard drives and connect them using programs into one hard drive array, which will have a lower cost. In this situation, you should use a more complex method.
Configuring a Raid array and installing the latest versions of Windows operating systems on it
After creating a software Raid array using the operating system tools, many users begin to wonder whether it is possible to install the operating system itself on this Raid and whether it is possible to transfer an already pre-installed and filled Windows array to the created Raid 1 array. There is a high probability that the hard drive itself with the operating system and all programs, and not just the hard drive, on which there is a set of files, can fail.
It should be noted that if a hard drive with an operating system and all files stops working in a company, then it will suspend its activities immediately for a number of days. Therefore, the procedure for creating a Raid array with an installed operating system belongs to the category of mandatory processes.
It is also worth considering that in addition to the Raid 1 array, there is also the possibility of creating a Raid 0 array. The second allows you to significantly increase the speed of the operating system.
In this article we will try to figure out how you can create a Raid 1 array from two hard disks and install an operating system on it. In this case, the motherboard can be any.
It should be noted that you can use the method of regular BIOS launch and the use of Raid technology. You need to select it to transfer an already installed operating system to it using a different set of utilities. First, however, we will take a look at how you can install Windows.
To get started, you need to create in the simplest way a USB flash drive for boot purposes.
In order to assemble a Raid 1 array, you need to stock up on two hard drives or SSD drives. It is very important to check whether a particular motherboard model supports Raid technology. You can purchase a pair of hard drives with a capacity of 250 gigabytes.
They must be placed in the system unit in the correct way.
In order to configure the system with the Raid array, open the BIOS and select the appropriate section there. Each model of computer device will have their own.
After turning on the computer device, you must enter through the BIOS and press the Delete key.
In the window that appears, visit the Advanced section and open it. Select SATA Configuration from the list.
You must set the Raid position to Sata Mode Selection.
HotPlug should be in the Enabled position for the hard drives that we will be combining into Raid.
In order for all settings to be saved, press the F10 button. Then the procedure for restarting the computer device will occur.
In order to go to the Raid configuration settings, the system prompts us to press CTRL + I with its notification. This action should be taken.
On the new page that appears, you need to find the Create a Raid Volume item and click on it. After that, immediately press Enter.
On the new page, you must enter the name of the Raid array. It can be anything. To enter the Raid name, press the space bar.
After entering the name, press Enter.
In the new window, we need to select Raid1 (Mirror). If this is not done, then all data will remain on the other hard drive. The controller will be on another hard drive in automatic mode.
Settings are made using the arrow keys on the keyboard. After they are carried out, you must click on Create Volume and on Enter.
A new window will display a warning about the user's consent that his data may be lost. In it, you need to click on Yes using the Y button.
Thus, it turns out that the creation of Raid 1 is complete and you can exit by pressing the esc button.
To agree to exit, you need to click again on Y.
After restarting the computer device, you need to go to the boot menu and select a USB flash drive from the list of priority downloads. The Raid that we created earlier should also be here.
Then select Install.
In a new window, after reading the license agreement, click on Accept.
On the page that appears, select the second item.
Now it is noticeable that the system detects two hard drives that were combined into a Raid array as a single whole.
On the Connect page, you must select Skip this step.
In the new window, you need to Use the standard parameters.
You can create a local account and click on done.
Today we will learn interesting information about what a RAID array is and what role these arrays play in the life of hard drives, yes, in them.
The hard drives themselves play a rather important role in the computer, since with the help of them we start the system and store a lot of information on them.
Time passes and any hard drive can fail, it can be any that we are not talking about today.
I hope that many have heard of the so-called raid arrays, which allow not only to speed up the work of hard drives, but also, if something happens, to save important data from disappearing, perhaps forever.
Also, these arrays have serial numbers, which makes them different. Each has a different function. For example, there is RAID 0, 1, 2, 3, 4, 5 etc. Today we will talk about these very arrays, and then I will write an article on how to use some of them.
What is a RAID array?
RAID Is a technology that allows you to combine several devices, namely, hard drives, in our case something like a bundle of them goes. Thus, we improve data storage reliability and read / write speed. Perhaps one of these functions.
So, if you want to either speed up your disk or just secure your information, it's up to you. More precisely, it depends on the choice of the required configuration of the "Raid", these configurations are marked with serial numbers 1, 2, 3 ...
Raids are a very useful feature and I recommend everyone to use it. For example, if you use 0th configuration, then you will feel an increase in the speed of the hard disk, after all, the hard disk is almost the lowest-speed device.
If you ask why, then I think everything is clear. every year they become more powerful, they are equipped with a higher frequency, more cores, and much more. The same with and. And so far, hard drives are growing only in volume, and the turnover rate has remained as it was 7200, and has remained. Of course, there are also rarer models. The situation is still being saved by the so-called, which speed up the system several times.
Let's say you went to build RAID 1, in this case, you will receive a high guarantee of the protection of your data, since they will be duplicated on another device (disk) and if one hard disk fails, all information will remain on the other.
As you can see from the examples, raids are very important and useful and should be used.
So, a RAID array is physically a bundle of two hard disks connected to the motherboard, you can either three or four. By the way, it should also support the creation of RAID arrays. Connecting hard drives is carried out according to the standard, and the creation of raids takes place at the software level.
When we programmatically created the raid, nothing really changed by eye, you just work in the BIOS, and everything else will remain as it was, that is, looking into My Computer, you will see all the same connected disks.
It doesn't take much to create an array: a motherboard with RAID support, two identical hard drives ( it is important). They should be the same not only in volume, but also in cache, interface, etc. It is desirable that the manufacturer is the same. Now we turn on the computer and, there we are looking for the parameter SATA Configuration and put on RAID... After restarting the computer, a window should appear in which we will see information about disks and raids. There we must press CTRL + Ito start configuring the raid, that is, add or remove disks from it. Then its setting will begin.
How many raids are there? There are several of them, namely RAID 1, RAID 2, RAID 3, RAID 4, RAID 5, RAID 6... In more detail, I will talk about only two of them.
- RAID 0 - allows you to create a disk array in order to increase the read / write speed.
- RAID 1 - allows you to create mirrored disk arrays for data protection.
What is RAID 0?
Array RAID 0, also called "Striping" uses 2 to 4 hard drives, rarely more. They work together to increase productivity. Thus, the data with such an array is divided into data blocks, and then written to several disks at once.
Performance is improved because one block of data is written to one disk, to another disk, another block, and so on. I think it is clear that 4 disks will increase performance more than two. If we talk about security, then it suffers on the entire array. If one of the disks fails, then in most cases, all information will be lost forever.
The fact is that in a RAID 0 array, information is located on all disks, that is, the bytes of a file are located on several disks. Therefore, if one disk fails, a certain amount of data will be lost, and recovery is impossible.
It follows from this that it is necessary to make permanent on external media.
What is RAID 1?
Array RAID 1, it is also called Mirroring - mirror. If we talk about the drawback, then in RAID 1 the volume of one of the hard disks is, as it were, "unavailable" to you, because it is used to duplicate the first disk. In RAID 0 this space is available.
From the advantages, as you probably already guessed, it follows that the array provides high data reliability, that is, if one disk fails, all data will remain on the second. Failure of two disks at once is unlikely. Such an array is often used on servers, but this does not prevent it from being used on ordinary computers.
If you choose RAID 1, then know that performance will drop, but if data is important to you, then use the data approach.
What is RAID 2-6?
Now I will briefly describe the rest of the arrays, so to speak, for general development, and all because they are not as popular as the first two.
RAID 2 - needed for arrays that use Hamming code (not interested in what kind of code). The principle of operation is approximately the same as in RAID 0, that is, the information is also divided into blocks and alternately written to disks. The rest of the disks are used to store error correction codes, with the help of which, in the event of a failure of one of the disks, you can restore data.
True, for this array it is better to use 4 disks, which is quite expensive, and as it turned out, when using so many disks, the performance gain is rather controversial.
RAID 3, 4, 5, 6 - I will not write about these arrays here, since the necessary information is already on Wikipedia, if you want to know about these arrays, then we read.
How to choose a RAID array?
Suppose that you often install various programs, games and copy a lot of music or movies, then you are advised to use RAID 0. When choosing hard drives, be careful, they must be very reliable so as not to lose information. Be sure to back up your data.
Is there important information that needs to be safe and sound? Then RAID 1 comes to the rescue. When choosing hard drives, their characteristics must also be identical.
Output
So we have sorted out for someone new, but for someone old information on RAID arrays. I hope this information is useful to you. I will write about how to create these arrays soon.
The problem of increasing the reliability of information storage is always on the agenda. This is especially true for large amounts of data, databases on which the operation of complex systems in a wide range of industries depends. This is especially important for high-performance servers.
As you know, the performance of modern processors is constantly growing, for which modern ones clearly do not keep pace in their development.
hard drives. The presence of one disk, be it SCSI or, even worse IDE, is already can't decide tasks relevant to our time. You need a lot of disks that will complement each other, replace if one of them is released, keep backups, work efficiently and efficiently.
However, just having multiple hard drives is not enough, you need them integrate into the systemthat will work smoothly and prevent data loss in case of any disk-related failures.
You need to take care of creating such a system in advance, because, as the well-known proverb says - while fried cock will not bite - will not be missed. You can lose your data irrevocably.
This system can be RAID - technology of virtual storage of information, combining several disks into one logical element. RAID array is called redundant array independent disks. Usually used to improve performance and reliability.
What do you need to create a raid? At least two hard drives. The number of storage devices used varies depending on the level of the array.
What are raid arrays
There are basic, combined RAID arrays. The Berkeley, California Institute proposed to split the raid into specification levels:
- Basic:
- RAID 1 ;
- RAID 2 ;
- RAID 3 ;
- RAID 4 ;
- RAID 5 ;
- RAID 6 .
- Combined:
- RAID 10 ;
- RAID 01 ;
- RAID 50 ;
- RAID 05 ;
- RAID 60 ;
- RAID 06 .
Let's consider the most frequently used ones.
Raid 0
RAID 0 intended to increase speed and recording. It does not increase storage reliability, and therefore is not redundant. His name is also stripe (striping - "striping"). Usually used by from 2 to 4 discs. 
The data is divided into blocks, which are written in turn to disks. Speed read / write increases by a multiple of the number of disks. Of disadvantages the increased likelihood of data loss with such a system can be noted. It makes no sense to store databases on such disks, because any serious glitch will lead to the complete inoperability of the raid, since there are no recovery tools.
Raid 1
RAID 1 provides mirror storage of data at the hardware level. Also called an array Mirror, What means « mirror»
... That is, the data of the disks in this case is duplicated. Can use with the number of storage devices from 2 to 4. 
Speed writing / reading practically does not change, which can be attributed to advantages... The array works if at least one disk of the raid is in operation, but the volume of the system is equal to the volume of one disk. In practice, when failure one of the hard drives, you will need to take measures to replace it as soon as possible.
Raid 2
RAID 2 - uses the so-called hamming code... Data is partitioned across hard drives in the same way as RAID 0, the remaining drives are stored error correction codes, in case of failure on which you can regenerate information. This method allows on the fly findand then correct system crashes. 
Rapidity read / write in this case versus using one disk rises... The downside is the large number of disks, in which it is rational to use it so that there is no data redundancy, usually 7 and more.
RAID 3 - In an array, data is split across all but one disk, which stores parity bytes. Resistant to system failures... If one of the disks breaks down... Then its information is easy to "raise" using the data of the parity checksums. 
Compared to RAID 2 no possibility error correction on the fly. This array is different high performance and the ability to use from 3 disks or more.
The main minus such a system can be considered an increased load on the disk storing parity bytes and low reliability of this disk.
Raid 4
In general, RAID 4 is similar to RAID 3 with that the differencethat the parity data is stored in blocks rather than bytes, allowing for faster transmission of small data.
Minus the specified array turns out to be the write speed, because write parity is generated on a single disk, like RAID 3. 
This is a good solution for those servers where files are read more often than written.
Raid 5
RAID 2 through 4 have disadvantages related to the inability to parallelize write operations. RAID 5 eliminates this flaw. Parity blocks are written at the same time to all disk devices in the array, no asynchrony in data distribution, which means parity is distributed. 
Number used hard drives from 3. The array is very common due to its universality and profitability, the more disks will be used, the more economical disk space will be spent. Speed wherein high due to data parallelization, but performance decreases in comparison with RAID 10, due to the large number of operations. If one drive fails, reliability is degraded to RAID 0. It takes a long time to recover.
Raid 6
RAID 6 technology similar to RAID 5, but increasing reliability by increasing the number of parity disks. 
However, disks already require at least 5 or more powerful processor to handle the increased number of operations, and the number of disks must be equal to a prime number of 5,7,11 and so on.
Raid 10, 50, 60
Next come combinations of the previously mentioned raids. For example, RAID 10 is RAID 0 + RAID 1. 
They inherit and advantages their constituent arrays in terms of reliability, performance and number of disks, and at the same time efficiency.
Creating a raid array on a home PC
The advantages of creating a raid array of a house are not obvious, due to the fact that it uneconomical, data loss is not so critical in comparison with servers, and information can be stored in backups, periodically making backups.
For these purposes you will need raid controller, which has its own BIOS and its own settings. In modern motherboards, the raid controller can be integrated to the south bridge of the chipset. But even in such cards, another controller can be connected by connecting to a PCI or PCI-E slot. Examples include devices from Silicon Image and JMicron.
Each controller can have its own configuration utility.
Consider creating a raid using the Intel Matrix Storage Manager Option ROM.
Transfer all data from your disks, otherwise they will be cleared.
Go to BIOSSetup Your motherboard and turn on the operating mode RAID for your sata hard drive. 
To run the utility, restart your PC, click ctrl + i during the procedure POST... In the program window you will see a list of available disks. Click Create massive, Next select required array level.
Further following the intuitive interface enter array size and confirm its creation.
Hello to all readers of the site! Friends, I have long wanted to talk to you about how to create a RAID array (redundant array of independent disks) on a computer. Despite the seeming complexity of the question, in fact, everything is very simple and I am sure that many readers immediately after reading this article will adopt and will be happy to use this very useful technology related to the security of your data.
How to create RAID array and why is it needed
It's no secret that our information on a computer is practically not insured by anything and is located on a simple hard disk, which tends to break down at the most inopportune moment. It has long been recognized that the hard drive is the weakest and most unreliable place in our system unit, since it has mechanical parts. Those users who have ever lost important data (including myself) due to the failure of the "screw", after burning for a while, wonder how to avoid such a nuisance in the future, and the first thing that comes to mind is creating a RAID array.
The whole point of a redundant array of independent disks is to save your files on the hard disk in the event of a complete disk failure! How to do this - you ask, but it's very simple, you only need two (maybe even different in size) hard drives.
In today's article, we will use the Windows 8.1 operating system to create the simplest and most popular of two blank hard drives RAID 1 array, it is also called "mirroring". The meaning of the "mirror" is that information on both disks is duplicated (written in parallel) and the two hard drives are exact copies of each other.
If you copied a file to the first hard disk, then exactly the same file appears on the second, and as you already understood, if one hard disk fails, then all your data will remain intact on second hard drive (mirror). The likelihood of breaking two hard drives at once is negligible.
The only drawback of a RAID 1 array is that you need to buy two hard drives, and they will work as one single one, that is, if you install two 500 GB hard drives in the system unit, then the same 500 will be available for storing files. GB, not 1TB.
If one of the two hard drives fails, you just take and replace it, adding it as a mirror to the already installed data hard drive and that's it.
Personally, for many years, i use at work RAID 1 array of two 1 TB hard drives and a year ago there was a nuisance, one "hard" ordered to live a long time, I had to replace it right there, then I thought with horror that if I didn't have a RAID array, a little chill ran through on the back, because the data accumulated over several years of work would have disappeared, and so, I just replaced the faulty "terabyte" and continued working. By the way, at home I also have a small RAID-array of two 500 GB hard drives.
Creation of softwareRAID 1 an array of two empty hard drives using Windows 8.1
First of all, we install two blank hard disks in our system unit. As an example, I'll take two 250GB hard drives.
Opening Disk Management
Disc 0 - SSD solid state drive with Windows 8.1 operating system installed on partition (C :).
Disc 1 and Disc 2 - hard drives with a capacity of 250 GB from which we will assemble a RAID 1 array.
Right-click on any hard drive and select "Create Mirrored Volume"
Add a disk that will be a mirror for the previously selected disk. We selected Disk 1 as the first mirrored volume, so on the left side we select Disk 2 and click on the "Add" button.
We select the letter of the software RAID 1 array, I leave the letter (D :). Further
Check the box Quick formatting and click Next.
In disk management, mirrored volumes are shown in blood red and have a single drive letter, in this case (D :). Copy any files to any disk and they will immediately appear on another disk.
In the "This PC" window, a software RAID 1 array appears as one disk.
If one of the two hard disks fails, the RAID array will be flagged with a Failed Redundancy error in disk management, but all data on the other hard disk will be intact.
Just the other day, I finally made my long-awaited little "upgrade": in addition to the already operating SEAGATE ST3120026AS hard drive, I purchased SEAGATE ST3120813AS. The essence of the purchase, as it seemed to me, had to resolve two of my pressing problems, namely: the recent catastrophic shortage of disk space or, more simply, free "GIGO-SHMIGO bytes" and the extremely low (by my standards) speed of the disk subsystem. The first problem is complete arithmetic clarity, which can be reduced to an addition level problem. But the second, which is a partial consequence of the first, involved the creation of a certain array of media in order to increase the speed of read and write operations. And I decided to make a RAID ...
I will briefly recall the main provisions describing the functioning of a zero-level RAID array, as the most appropriate in my particular case. I'll start with a pleasant one, that is, with a listing of the positive aspects. Level 0 RAID array:
STEP 1 - Pros and Cons
Theoretically, a twofold increase in the speed of the disk subsystem (read acceleration of read and write operations), on the "practical test range" gives a result far from transcendental (double gain) and is from 30 to 50% percent, which is still quite good, given the fact that most manufacturers initially put support for this feature into the south bridge and an end user like me does not have to shell out money for a separate expansion fee. For clarity, I will give an agit leaflet from Intel ...
The picture, in my opinion, is very commercially attractive, but there is one flaw in it - the numbers are overstated. Expressed in relative units (the conditional speed of devices relative to the speed of one IDE screw), the performance is measured in test packages, and therefore cannot reflect the real picture of the chaotic work of an ordinary user on a computer. Yes, there is certainly an increase and, as I mentioned earlier, from 30 to 50 percent, depending on the specifics of the work performed on the PC, but a pair of SATA screws installed in RAID 0, in real life, it seems to me rarely when an ordinary IDE screw is equipped with 76% , if only it is not covered with badges .... "Let's go" further: picture number two ....
The diagram shows the 865PE in person, I want to pay attention to the speed, or more precisely the bandwidth of the channels ... Let me explain, for example, according to the figure, the "percent" is "used" with the north bridge at the maximum theoretical speed 6.4, 4.3, 3.2GB / s, the spread of speeds is associated with different options for the system bus frequency: 800/533 / 400MHz, then the memory is exchanged for 6.4GB / S, with a video card for 2GB / s, but the south bridge with a SATA screw will work at the maximum possible 150 MB / s. Thus, it is time to mention here a beautiful phrase like "bottleneck", which in normal translation means only one thing - the bottleneck in any PC is initially the disk subsystem. Based on this and returning to the above, it becomes clear that even a 30-50 percent increase is a huge plus to the speed of the entire system. "Let's go" further: picture number three ....
The picture is nothing more than a confirmation of the very possibility - taken from the instructions for the ASUS P4P800 motherboard, the R index in the south bridge marking just indicates this. "Let's go" further: picture number 4 ....
Briefly: the principle of operation of a RAID 0 array is to write data in parallel to two media at once, based on the division of the data stream by the controller (when reading, the reverse process occurs). That's where the performance gain comes from.
We pass to the "minuses", or negative sides of the "resulting structure". One of the obvious drawbacks is the inability to use media separately from the array, i.e. the functionality of the array elements is limited by the framework of the system being created. An "extremely inflated" minus in my opinion is the statement about the extreme degree of instability and unreliability in data storage, in case of an unexpected "death" of a component of the array (hard drive), the data system dies next. I agree that the problem really gets worse with the increase in the number of drives participating in the creation of a RAID array, because theoretically the risk of system failure increases, which is the sum of the risks of failure of individual array elements. But do not forget that in practice RAID arrays do not "fly" more often than their single counterparts. The financial side of the issue is also not in favor of RAID, one hard drive of double capacity is about one and a half times cheaper than two drives of equal (single) capacity. Doubling the number of drives also results in increased system power consumption, which can be fatal in systems with low power supplies. Alas, no one removed the acoustic question from the agenda - the noise, although not double, from the use of RAID, is still noticeably higher. To summarize all the disadvantages, I would say that they are half-hearted. And this half-heartedness lies in the apparent seriousness of the negative sides, in practice most of them are quite surmountable.
STEP 2 - What is required for ....
To create a zero-level RAID array, you must have at least two drives of identical capacity and identical interfaces. It is desirable, and I would say it is imperative, that the drives are as similar as possible in technical terms, that is, the parameters affecting the device's performance were similar (buffer size, average seek time, etc.). Motherboard manufacturers offering support for RAID arrays in their "offspring" strongly recommend using only identical disks in the array! And this appeal has a very serious "ground", first of all, this is due to the achievement of maximum performance (we abstract from reality and believe that two identical drives will work the same) and at the same time a significant reduction in problems with the subsequent operation of the array. It is logical to believe that a RAID created from heterogeneous (not in terms of capacity and connection interface, but in terms of technical characteristics) disks will be somewhat "lopsided" one of the devices, which has a much lower performance, will in a way slow down the entire array. I will not hide, these are just my guesses, but I am sure on "real" test applications they will translate into a significant decrease in performance compared to an array of homogeneous drives. Next, you need to support the creation of a RAID array by the south bridge of the motherboard. As for the powerful power supply unit, the situation in no way resembles the SLI mode, which requires truly "animal" power from the power supply unit or power supplies. Unless you have a Chinese noname of 250 watts or a 100% loaded car, then you will most likely pass the energy requirements. Without being unfounded, I will give an example of my machine, a 300 watt PowerMan functions as a power supply unit, while a Pentium 4 2.8GHz processor (Presscott stepping C0, heats up terribly), overclocked to 3.36, gig operatives with 2 512 KingStone strips, video card read, Audigy, TV tuner Aver Media 203rd, DVD-RW drive, 2 screws mentioned above, and enough power ...
STEP 3 - Install and Create RAID Level 0
We connect two SATA disks with interface cables to the motherboard. All subsequent manipulations are performed on a software level. The attached print screens are excerpts from the instructions for installing and configuring REID, alas, I can not remove my own no digicam :(. First of all we go into the BIOS .....
We translate the highlighted option to YES, thereby activating support for the RAID function at the BIOS level. We save and exit, after the reboot we see the picture ...
The meaning of the displayed information boils down to the following: the REID array does not include a single disk, and not the Raid ones "hang" on ports 0 and 1, indicating their marking, status, and the ability to boot from them. Next, it is suggested to press CTRL + I to "visit" the configuration utility. What we actually do:
Briefly about the menu:
1. Creating a Raid Array.
2. Removing the Raid array.
3. Reset disks to their original, non-Raid state.
We select the first item and go ...
On this tab we select the size of the "stripe" (translated from English :), ours - 128KB - the best performance for most home computers and workstations. Next, select the type of REID - RAID 0 and finally click Create Volume.
Do you really want to create a REID array - such persistent warnings like a warning, as if we are launching Gagarin into space. We press "ENTER" ..... We get the result ...
The only note is that when installing Windows XP, at the first stage, press F6 when asked, and install the drivers from a previously created floppy disk for the normal detection of REID. And here's what the visual confirmation looks like that my drives are working in a REID array ..
STEP 4 - Summary (very brief)
Not the most sophisticated test suite showed the following result:
It should be noted that the indicators of SATA 150 and ATA UltraDMA 6 according to my observations are purely hypothetical, since I remember from memory that the values \u200b\u200bI obtained for these positions were always lower than the "exemplary" ones, so for SATA 150, at a time when I had one screw from SEAGATE the result was somewhere in the region of 126-135MB / s. These are the pies ... So, working now on a system with a RAID array, I can say with full confidence that it is worth it, the gain is not colossal and does not bring staggering acceleration to the system, but it is stable and very noticeable and feel not only with the "test eye" ...
p.s And don't forget to put a radiator on the south bridge :)
Maslenkov Andrey
Operational practice shows that a zero-level read array gives excellent speed indicators, which is indirectly confirmed in the results of synthetic tests sent to me by a site visitor Igor Alexandrovich on his system, the configuration of which is presented below:
