Promise Array Management

Striping / Mirroring (RAID 0+1)

A combination of RAID 0 and RAID 1 arrays. It can increase performance by

reading and writing data in parallel while protecting data with duplication. A

minimum of four drives are required.

With a four-drive disk array, two pairs of drives are striped. Each pair mirrors the

data on the other pair of striped drives. The data capacity is similar to a standard

Mirroring array with half of total capacity dedicated for redundancy.
