Disk And Media Features - IBM Power 720 Overview

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.
Remember:
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.
