Assigning a disk for use as a global spare does not reserve space on that disk An automatic restore is not guaranteed if a disk fails If there is not enough disk space on the global spare make room for the fail over to complete or assign a different disk with enough capacity as the spare If there is enough space available on the global spare and a disk failure occurs the restore process starts automatically For additional information see Add or Remove Global Spares on page 61 24 Arrays Disks and RAID Levels RAID Performance Considerations With RAID technology performance is based on the following considerations e The number and organization of disks in an array e Caching attributes used for the array e Application workload Number and Organization of Disks RAID functions increase performance by putting more disks to work and by buffering data for the host Many disks can transfer data at greater than 50 MB per second RAIDXpert2 can aggregate this bandwidth in an almost linear fashion as more of the same disks are included in an array Caching Attributes RAIDXpert2 can also be configured to provide read and Write Back caching if desired Write Back caching has a large effect on most workloads but should be used with caution Application Workload When configuring an array workload is probably the most important performance variable Most applications do many more reads than writes The best performance is obta
