9. Facts e Each array may have several hot spare drives If a drive in a RAID 5 1 or 1 0 volume fails a hot spare drive is assigned and the Sun StorEdge RAID Manager Sun StorEdge A1000 array or VERITAS Volume Manager software Sun StorEdge D1000 array detects the failure and automatically rebuilds the data from the failed drive onto a hot spare drive e Striped data organizations RAID 0 1 0 3 and 5 can be tuned to optimize for either random or sequential I O performance e To optimize for random performance the I O load must be evenly balanced across the disk spindles This is done by setting the stripe width as large or larger than the typical application I O request For example if the typical I O request is 8 KB setting the stripe width to 64 KB might be appropriate This tends to evenly distribute I O requests across all the disk spindles in the LUN e Sequential performance is optimized when data is spread out so that each application I O spans all the drives in the RAID group This requires setting the stripe width so that it is small relative to the size of the typical I O request For example in a RAID group with four data disks if typical application I O size is 8 KB to 16 KB a stripe width of 2 KB may be best S amp SUN Just the Facts microsystems August 1999 1N 99 142 IY JEMYOS System Management Performance Summary e The Sun StorEdge A1000 array s highest bandwidth is 32 MB per second when performing
