How to Configure RAID on the BIOS Page

How to Configure RAID on the BIOS Page

This Avago SAS3508 RAID (TaiShan 200 server) is used as an example to describe how to configure RAID on the BIOS page.

Impact on the System

You need to restart the server to access the configuration management page, which will interrupt services on the server.

Procedure

  1. Access the server desktop using the Remote Virtual Console.
  2. Restart the server.
  3. During the restart process, press Delete when information shown in Figure 13-7 is displayed.

    Figure 13-7 BIOS boot screen

  4. Type the password and press Enter.

    The screen is displayed in Figure 13-8.

    The default BIOS password is Admin@9000.

    The default BIOS password of TaiShan 2280 and 5280 servers is Huawei12#$. The default BIOS password of other TaiShan servers is Admin@9000.

      Figure 13-11 Create Virtual Drive screen (1)
      Figure 13-12 Create Virtual Drive screen (2)
      Table 13-9 Parameter description

      Parameter

      Description

      Select RAID Level

      Selects a RAID level.

      Protect Virtual Drive

      Status of virtual drive data protection.

      Select Drives From

      Source of member drives of the virtual drive.

      Member drive sources are as follows:

      • Unconfigured Capacity: Idle drives that are not added to any virtual drives.
      • Free Capacity: Remaining space of the virtual drive.

      Select Drives

      Selects member drives.

      Virtual Drive Name

      Name of the virtual drive.

      Virtual Drive Size

      Capacity of the virtual drive. The default value is the current largest capacity supported.

      Virtual Drive Size Unit

      Unit of capacity.

      Strip Size

      Strip size of the virtual drive. Options include 64 KB, 128 KB, 256 KB, 512 KB, and 1 MB.

      Read Policy

      Read policy of the virtual drive. The options are as follows:

      • No Read Ahead: disables the Read Ahead function.
      • Read Ahead: enables the Read Ahead function. The controller pre-reads sequential data or the data predicted to be used and saves it in the cache.
      NOTE:

      To achieve optimal disk performance, set the policy to Read Ahead for HDDs and No Read Ahead for SSDs.

      Write Policy

      Write policy of the virtual drive. The options are as follows:

      • Write Back: Once all data in the cache is received, the controller card notifies the host that data transmission is complete.
      • Write Through: Once the drive subsystem receives all data, the controller card notifies the host that data transmission is complete.
      • Always Write Back: The controller card goes to the Write Back mode when supercapacitor is absent or faulty.
      NOTE:

      In Always Write Back mode, DDR write data of the controller card will be lost if the supercapacitor is not installed or being charged. This mode is not recommended.

      I/O Policy

      I/O policy of the virtual drive. The policy does not affect the Read Ahead function. The options are as follows:

      • Direct: has different definitions in read and write scenarios.
        • In a read scenario, data is directly read from hard drives. (If Read Policy is set to Read Ahead, data is read from the RAID cache.)
        • In a write scenario, data is written into the RAID cache. (If Write Policy is set to Write Through, data is directly written into hard drives.)
      • Cached: Data is read from or written into the RAID cache. Set IO policy to Cached only when configuring CacheCade 1.1.

      Access Policy

      Data access policy. The options are as follows:

      • Read/Write: Read and write operations are allowed.
      • Read Only: The virtual drive is read-only.
      • Blocked: The virtual drive is blocked from access.

      Drive Cache

      Physical hard drive cache policy. The options are as follows:

      • Unchanged: uses the current cache policy.
      • Enable: writes data to the cache before writing data to the hard drive. This option improves data write performance. However, data will be lost if there is no protection mechanism against power failures.
      • Disable: writes data to a hard drive without caching the data. Data is not lost if power failures occur.

      Disable Background Initialization

      Enables or disables background initialization.

      Default Initialization

      Default initialization mode. The options are as follows:

      • No: Initialization is not performed.
      • Fast: Fast initialization.
      • Full: Full initialization.

      Emulation Type

      Sets the sector size reported to the OS.

      • Default: If there are any 512e drives in member drives, the physical bytes per sector are shown as 512e (4k). If there are no 512e drives, the physical bytes per sector are shown as 512n.
      • Disable: If there are no 512e drives in member drives, the physical bytes per sector are shown as 512n.
      • Force: Even though there are no 512e drives in member drives, the physical bytes per sector are shown as 512e (4k).
