operations. It can withstand two simultaneous drive failures without downtime
or data loss. RAID 10 is mirroring and striping without parity. It is the most
popular of the multiple RAID levels, allowing large arrays with high
performance in most cases and superior fault tolerance. RAID 50 combines
the block striping and parity of RAID 5 with the straight block striping of RAID
0, yielding higher performance than RAID 5 through the addition of RAID 0,
particularly during writes.
Performance Performance Performance Performance Performance numbers are a guideline as established by tests in a lab
environment. Forty-eight 300GB 15K SAS drives were used in
dual controller configurations of four vDisks with 12 physical drives per
vDisk. Each vDisk presented a
single volume of maximum capacity according to RAID level.
Number and type of applications, number of hosts will affect overall
performance.
