207. uRAID 8 Series has been traditionally implemented using an even number of disks some hybrids can use an odd number of disks as well Illustration is an example of a hybrid RAID 1E array comprised of five disks A B C D and E In this configuration each strip is mirrored on an adjacent disk with wrap around In fact this scheme or a slightly modified version of it is often referred to as RAID 1E and was originally proposed by IBM When the number of disks comprising a RAID 1E is even the striping pattern is identical to that of a traditional RAID 1E with each disk being mirrored by exactly one other unique disk Therefore all the characteristics for a traditional RAID 1E apply to a RAID 1E when the latter has an even number of disks RAID 1E offers a little more flexibility in choosing the number of disks that can be used to constitute an array The number can be even or odd Chapter 1 Introduction Dae ary EL PME DM uuum hII Logical Disk 1 2 4 RAID 3 RAID 3 provides disk striping and complete data redundancy through a dedicated parity drive RAID 3 breaks up data into smaller blocks calculates parity by performing an exclusive or on the blocks and then writes the blocks to all but one drive in the array The parity data created during the exclusive or is then written to the last drive in the array If a single drive fails data is still available by computing the exclusive or of the contents in the corresponding strips of t
