  • Page 14: Understanding Raid Technology

    RAID levels that you assign to the logical drives. The ServeRAID controllers support RAID level-0, RAID level-1, RAID level-1 Enhanced (1E), RAID level-5 and RAID level-5 Enhanced (5E). IBM ServeRAID-3H, ServeRAID-3HB, and ServeRAID-3L, Controllers...

  • Page 15: Understanding Raid Level-0

    Understanding RAID level-0 RAID level-0 stripes the data across all the drives in the array. This offers substantial speed enhancement, but provides for no data redundancy. RAID level-0 provides the largest capacity of the RAID levels offered, because no room is taken up for redundant data or data-parity storage. RAID level-0 requires a minimum of one drive and, depending upon the level of firmware and the stripe-unit size, supports a maximum of eight or 16 drives.

  • Page 16: Understanding Raid Level-1

    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. IBM ServeRAID-3H, ServeRAID-3HB, and ServeRAID-3L, Controllers...

  • Page 17: Understanding Raid Level-1 Enhanced

    Understanding RAID Level-1 Enhanced If you have three or more physical drives in the array, you can no longer select RAID level-1, but you can select RAID level-1 Enhanced (also called RAID level-1E). RAID level-1E combines mirroring with data striping. This RAID level stripes data and copies of the data across all of the drives in the array.

  • Page 18: Understanding Raid Level-5

    Notice that the storage of the data parity (denoted by also is striped, and it shifts from drive to drive. A parity block ( ) contains a representation of the data from the other blocks in the same stripe. IBM ServeRAID-3H, ServeRAID-3HB, and ServeRAID-3L, Controllers...

  • Page 19: Understanding Raid Level-5 Enhanced

    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 (also called RAID level-5E) requires a minimum of four physical drives. RAID level-5E is also firmware-specific.
