  • Page 16: Stripe-Unit Size

    Stripe-unit size With RAID technology, data is striped across an array of physical drives. This data-distribution scheme complements the way the operating system requests data. The granularity at which data is stored on one drive of the array before subsequent data is stored on the next drive of the array is called the stripe-unit size.
  • Page 17 Create an array using the two physical drives. Then, create a logical drive within that array. The data is striped across the drives, creating blocks. Notice that the data is striped across all the drives in the array, but no redundant data is stored. A physical drive failure within the array results in loss of data in the logical drive assigned RAID level-0, but only in that logical drive.
  • Page 18 Because the data is mirrored, the capacity of the logical drive when assigned RAID level-1 is 50% of the array capacity. The following illustration shows an example of a RAID level-1 logical drive. Start with two physical drives. Create an array using the two physical drives. Then, create a logical drive within that array.
  • Page 19 RAID level-1E requires a minimum of 3 drives and, depending upon the level of firmware and the stripe-unit size, supports a maximum of 8 or 16 drives. The following illustration is an example of a RAID level-1E logical drive. Start with three physical drives. Create an array using the physical drives.
  • Page 20 RAID level-5 offers both data protection and increased throughput. RAID level-5 gives you higher capacity than RAID level-1, but RAID level-1 offers better performance. RAID level-5 requires a minimum of 3 drives and, depending upon the level of firmware and the stripe-unit size, supports a maximum of 8 or 16 drives. The following illustration is an example of a RAID level-5 logical drive.
  • Page 21 If a physical drive fails in the array, the ServeRAID controller switches read and write requests to the remaining functional drive in the RAID level-5 array, which is a hot-spare drive. Understanding RAID level-5 Enhanced RAID level-5 Enhanced (RAID level-5E) requires a minimum of four physical drives. RAID level-5E is also firmware-specific.
  • Page 22 The operating system uses the spanned array logical drive the same as a regular array logical drive. Note: RAID level-x0 is only available on the IBM ServeRAID-4H Ultra160 SCSI controller. RAID level-x0 requires a minimum of 2 drives and supports a maximum of 60 drives.
  • Page 23 The following illustration is an example of a RAID level-10 logical drive. Start with six physical drives. Create three arrays (labeled A, B, and C), each array using two physical drives. Then, create a spanned array 1 1 1 (labeled as 1) that spans the three arrays.
  • Page 24: Selecting A Raid Level And Performance Tuning

    RAID level means the sub-logical drive is and the spanned array logical drive is RAID level-0 RAID level-0 RAID level-1 RAID level-0 RAID level-1E RAID level-0 RAID level-5 RAID level-0 With RAID level-10, 1E0, and 50, if one of the physical drives fails in a sub-logical drive, the ServeRAID controller switches read and write requests to the remaining functional drives in the sub-logical drive.
  • Page 25 Drive State Meaning Ready The ServeRAID controller recognizes a ready drive as being available for definition. Standby Hot A standby hot spare is a hot-spare drive that the ServeRAID controller Spare has spun down. If an online drive becomes defunct and no suitable hot-spare drive is available, a standby hot-spare drive of the appropriate size automatically spins up, and enters the rebuild state.

  • Page 31: Using A Serveraid Controller In A Server With Hot-Plug Pci Features

    To use Hot-plug PCI with Windows NT 4.0 and a ServeRAID-4H controller, you must install the IBM Netfinity Hot Plug for Windows NT 4.0 Package, version 4.1 or later. This package is available from the IBM Support Web site; select downloadable files for the IBM Netfinity server you are using.
  • Page 32 Note: Some IBM Netfinity servers support Hot-plug PCI features, which allow you to install or remove PCI controllers without turning off the server. If your Netfinity model provides Hot-plug PCI support and you are using Windows NT, Windows 2000, or NetWare 5.x, you do not need to turn off your server to install this controller.

  • Page 40 Attention: The new controller stripe-unit size is set at the factory to 8 KB. If you need to change this setting, you must change the stripe-unit size before you store data in the logical drives. After you store data in the logical drives, you cannot change the stripe-unit size without destroying data in the logical drives.
