There is no data redundancy. All data is lost if any drive fails.•RAID 1 (drive mirroring): Data is written simultaneously to both drives in the drive group, providing complete data redundancy if one drive fails. RAID 1 supports an even number of drives from 2 to 32 in a single span.•RAID 5 (drive striping with distributed parity): Data is striped across all drives in the group. Part of the capacity of each drive stores parity information that reconstructs data if a drive fails. RAID 5 provides good datathroughput for applications with high read request rates.•RAID 00 (data striping across RAID 0 drive groups): RAID 00 is a spanned drive group that creates a striped set from a series of RAID 0 drive groups.Attention:The battery in the ServeRAID M5000 Series Battery Assembly must charge for at least sixhours under normal operating conditions. Toprotect your data, the firmware changes the WritePolicy to write-through until the battery unit issufficiently charged. When the battery unit ischarged, the controller firmware changes theWrite Policy to write-back to take advantage ofthe performance benefits of data caching.IBM P/N: 49Y0898First Edition (June 2009)© Copyright International Business Machines Corporation 2009.
