  • Page 37: Chapter 3. Understanding Raid Technology

    This grouping technique greatly enhances logical-drive capacity and performance beyond the physical limitations of a single physical drive. When you group multiple physical drives into a logical drive, the ServeRAID controller can transfer data in parallel from the multiple drives in the array. This parallel transfer yields data-transfer rates that are many times higher than with nonarrayed drives.

  • Page 38: Selecting A Raid Level And Tuning Performance

    Generally, the more drives in the array, the better the performance. Supported RAID levels The ServeRAID controllers support RAID level-0, level-1, level-1E, level-5, level-5E, level-00, level-10, level-1E0, and level-50. The integrated RAID controllers support RAID level-1 only. The ServeRAID-5i controller does not support RAID level-5E.
  • Page 39 Understanding RAID level-0 RAID level-0 stripes the data across all the drives in the array. This offers substantial speed enhancement but provides no data redundancy. RAID level-0 provides the largest storage capacity of the RAID levels that are offered, because no room is taken for redundant data or data-parity storage.
  • Page 40 When you replace a failed drive, the ServeRAID controller can rebuild all the RAID level-1, level-1E, level-5, and level-5E logical drives automatically onto the replacement physical drive. However, any data stored in a failed RAID level-0 logical drive is lost.
  • Page 41 Notice that the data on the drive on the right is a copy of the data on the drive on the left. With RAID level-1, if one of the physical drives fails, the ServeRAID controller switches read and write requests to the remaining functional drive in the RAID level-1 array.
  • Page 42 Also, notice that each block on the mirror stripe is shifted one drive. With RAID level-1E, if one of the physical drives fails, the ServeRAID controller switches read and write requests to the remaining functional drives in the RAID level-1E array.
  • Page 43 The following illustration is an example of a RAID level-5 logical drive. Start with four physical drives. Create an array using three of the physical drives, leaving the fourth as a hot-spare drive. Then create a logical drive within that array.
  • Page 44 RAID level-5E, you can have a maximum of seven logical drives on the controller. The following illustration is an example of a RAID level-5E logical drive. Start with four physical drives. Create an array using all four physical drives. IBM ServeRAID: User’s Reference, Version 5.10...
  • Page 45 Higher performance than RAID level-5 v Cannot share a hot-spare drive with other arrays Note: The ServeRAID Manager program Configuration wizard does not default to RAID level-5E. If you have four physical drives, Express configuration defaults to RAID level-5 with a hot-spare drive.
  • Page 46 Understanding RAID level-x0 Note: RAID level-x0 is available only on the ServeRAID-4 and ServeRAID-5i controllers. RAID level-x0 refers to RAID level-00, level-10, level-1E0, and level-50. RAID level-x0 uses an array of arrays, or a spanned array. The operating system uses the spanned array logical drive in the same way as a regular array logical drive.
  • Page 47 RAID level-0 With RAID level-10, level-1E0, and level-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. With RAID level-00, a physical drive failure within the sub-logical drive results in loss of data.

  • Page 48: Drive-State Descriptions

    The ServeRAID controller recognizes a ready drive as being available for definition. Standby hot spare A standby hot spare is a hot-spare drive that the ServeRAID controller 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 49 If any of these is true, see “Rebuilding a defunct drive” on page 157. Okay The logical drive is working properly. It is in a good, functional state. System The ServeRAID controller uses this reserved state during logical-drive migration. Chapter 3. Understanding RAID technology...
