1.5 Disk and media features
The Power 720 and Power 740 systems feature an integrated SAS controller, offering
RAID 0, 1, and 10 support with two storage backplane options:
The FC 5618 option supports up to six SFF SAS HDDs or SSDs, a SATA DVD, and a
half-high tape drive for either a tape drive or USB removable disk. This feature does not
provide RAID 5, RAID 6, a write cache, or an external SAS port. Split backplane
functionality (3x3) is supported with the additional FC EJ02.
The FC EJ01 option is a higher-function backplane that supports up to eight SFF SAS
HDDs or SSDs, a SATA DVD, a half-high tape drive for either a tape drive or USB
removable disk, Dual 175 MB Write Cache RAID, and one external SAS port. The
FC EJ01 supports RAID 5 and RAID 6; no split backplane is available for this feature.
All HDDs/SSDs are hot-swap and front accessible.
