Pegasus32 R4/R6/R8

A RAID 5 on Pegasus R4 consists of three or four physical drives. A RAID 5 on Pegasus R6 consists of

three to six physical drives.

Recommended Applications for RAID 5:

•

File and Application servers

•

WWW, E-mail, and News servers

•

Intranet servers

RAID 6 – Block and Double Parity Stripe

RAID level 6 stores dual parity data is rotated across the physical drives along with the block data. A

RAID 6 logical drive can continue to accept I/O requests when any two physical drives fail.

Figure 5. RAID 6 stripes all drives with data and dual parity

Hence, a RAID 6 logical drive with (7) 100 GB physical drives has a capacity of 500 GB. A RAID 6

logical drive with (4) 100 GB physical drives has a capacity of 200 GB.

RAID 6 becomes more capacity efficient in terms of physical drives as the number of physical drives

increases.

RAID 6 provides double fault tolerance. Your logical drive remains available when up to two physical

drives fail.

RAID 6 is generally considered to be the safest RAID level. A RAID 6 on Pegasus R4 consists of four

physical drives.
