  • Page 57: Internal Sata Raid Controller

    EVGA Z790 CLASSIFIED (121-RL-E798) Internal SATA RAID Controller This section covers the basics of what RAID does, how RAID works, and why you may or may not want to use RAID. There are other means of creating a RAID drive on this...
  • Page 58 EVGA Z790 CLASSIFIED (121-RL-E798) RAID LEVELS There are three main considerations when creating a RAID array: performance, capacity, and redundancy. Fortunately, each RAID mode offered has unique characteristics that make choosing one fairly simple, based on your needs.  Performance – Quite simply, which array type is the fastest? o RAID0 is considered the best performance option here.
  • Page 59 EVGA Z790 CLASSIFIED (121-RL-E798) RAID0 : RAID0 is considered “Striping” or a “Striped Array.” RAID0 takes a data set and spreads it equally across two or more drives. Reading a file, for example, will be much faster if the file is spread across multiple drives and read from each drive simultaneously.
  • Page 60 EVGA Z790 CLASSIFIED (121-RL-E798) RAID5 : RAID5 is a stripe with fault tolerance, which attempts to bridge the gap between speed and redundancy. It is the most all-around type of array. This array-type will reserve, essentially, a capacity size equivalent to one drive for fault-tolerance. This means that if you use four 1TB drives to create your RAID5, you will only have the capacity of three 1TB drives.
  • Page 61 EVGA Z790 CLASSIFIED (121-RL-E798) RAID10 : RAID10 is a nested RAID, which is a type of RAID utilizing multiple arrays within a single configuration. This type of virtualization allows you to have an array where each node has its own level of redundancy. RAID10 is highly scalable, but this motherboard supports arrays of only four drives –...
  • Page 62 EVGA Z790 CLASSIFIED (121-RL-E798) Configuring the Array 1. Attach all SATA devices you intend to use, and make sure power is attached. Power the system on. Press the “Delete” key repeatedly to enter BIOS. Once into BIOS you will need to enable the RAID function of the board.
  • Page 63 EVGA Z790 CLASSIFIED (121-RL-E798) 3. Similar to the M.2 RAID instructions, set Enable VMD Controller to “Enabled”, then Save and Reboot. Upon entering the menu again, you will notice that your SATA port information will be empty. This mode includes both the RAID controls and the same options/functions/commands as AHCI.
  • Page 64 EVGA Z790 CLASSIFIED (121-RL-E798) 4. Return to the SATA Configuration menu and enter the Intel Rapid Storage ® Technology menu. 5. Once in the RAID controller, you will see a list of all detected drives and a “Create RAID Volume” button. To begin, click on “Create RAID Volume.”...
  • Page 65 EVGA Z790 CLASSIFIED (121-RL-E798) 7. Next, select your intended array type. Please see the bottom of Page 61 for a quick reference on different RAID levels and RAID types based on your total number of drives. For the purpose of this guide, we will make a RAID5.
  • Page 66 EVGA Z790 CLASSIFIED (121-RL-E798) 10. The controller defaults the capacity to the maximum available space for the RAID. Leaving the capacity at default is recommended because reducing the size is not beneficial, except in limited cases. 11. To complete the setup process, please select “Create Volume” at the bottom of the page.
  • Page 67 EVGA Z790 CLASSIFIED (121-RL-E798) 13. For OS installation, provided that the array is configured properly, the operating system will detect the array and see it as a single drive or a bootable RAID array – as opposed to several drives – and allow you to install the OS to the array without any further steps.
  • Page 68 EVGA Z790 CLASSIFIED (121-RL-E798) 1. To begin the repair, select the degraded RAID volume to see your array status and all remaining drives currently configured in the RAID array.

  • Page 74 EVGA Z790 CLASSIFIED (121-RL-E798) 4. The build progress will be displayed on the Manage page. Once the RAID is fully built, the percentage will disappear, and your array will be shown. For further information about the array or your drives, click on the array for more details, including the option to delete or repair the array, if necessary.
  • Page 75 EVGA Z790 CLASSIFIED (121-RL-E798) Repairing an array within IOMSM This section of the guide will illustrate how to repair a degraded array from within the IOMSM. For purposes of this guide, we will repair a degraded RAID1 array using a third drive plugged into the controller, but not currently in use.
  • Page 76 EVGA Z790 CLASSIFIED (121-RL-E798) Click “Rebuild to another disk” to begin the repair process. On the next page, the IOMSM will explain why you need to repair your drive, warn you that you will delete any data on the spare drive, and ask you to select the disk where you want to rebuild the array.
  • Page 77 EVGA Z790 CLASSIFIED (121-RL-E798) The rebuild process will begin. As with any RAID array with Fault Tolerance, the rebuilding time depends on several factors, such as array size, array type, CPU, etc. You may keep track of the rebuilding progress in the Manage tab. Once repairs are complete, the warning will disappear and the array will update to “Status: Normal.”...
  • Page 78 EVGA Z790 CLASSIFIED (121-RL-E798) Partitioning and Formatting a drive Once you have created your array, either from within the BIOS or from the IOMSM, you will not initially see your array in “This PC.” This is expected, because even though you have created the array, you have not yet prepared the array to be used.
