Handle multiple disk RAID Level Disk Striping Mirroring Parity failures? RAID 0 No. RAID 0 offers no data redundancy or protection against disk failure. RAID 0 should only be used for non- critical data. The failure of a single disk in a RAID 0 LUN will result in the loss of all data on the LUN.
Page 47
ÃÃ Relative Read Performance Relative Write Performance LUN Configuration for Large Sequential Access for Large Sequential Access RAID 0 The read and write performance of a RAID 0 LUN increases as the multiple of the number of disks in the LUN. For example, a 4-disk RAID 0 LUN will achieve close to four times the performance of a single disk.
Page 48
RAID Level General Performance Characteristics RAID 0 – Simultaneous access to multiple disks increases I/O performance. In general, the greater the number of mirrored pairs, the greater the increase in performance. RAID 1 – A RAID 1 mirrored pair requires one I/O operation for a read and two I/O operations for a write, one to each disk in the pair.
Page 49
RAID level Application and I/O Pattern Performance RAID 0 RAID 0 is a good choice in the following situations: – Data protection is not critical. RAID 0 provides no data redundancy for protection against disk failure. – Useful for scratch files or other temporary data whose loss will not seriously impact system operation.

Note RAID level Setting: Function: Sets the RAID level used by the LUN. Performance Impact: The RAID level selected impacts the entire performance profile for the LUN. Read I/O and write I/O performance are directly influenced by the RAID level. See "RAID Level Comparisons"...
Page 132
Cache flush threshold (default 80%) Setting: Function: Sets the level at which the disk array controller begins flushing write cache content to disk media. The setting is specified as the percentage of total available cache that can contain write data before flushing begins. The cache flush threshold can be set independently for each controller.
Page 133
Cache flush limit (default 100%) Setting: Function: Determines how much data will remain in write cache when flushing stops. It is expressed as a percentage of the cache flush threshold. For optimum performance this value is set to 100% by default. This ensures that the entire amount of cache specified by the cache flush threshold will contain write cache data, increasing the number of write cache hits.
