7.2.2 Active Midplane with Intel
®
SAS /SAS RAID Support
The active midplane is used to provide SAS/SAS RAID support. It has an integrated LSI
LSLSAS1078 3 Gb/s RAID On-a-Chip (ROC) device. It provides support for up to eight SAS
drives in this system. By default, this midplane option provides software RAID levels 0, 1, and
10 and utilizes Intel
®
IT/IR RAID. With the installation of optional RAID enablement devices, the
midplane can support hardware RAID levels 0, 1, 5, 10, 50, 6 and 60. The midplane attaches to
the hot-swap backplane by two card edge connectors, which eliminates the need for any hard
drive cables. The following sub-sections describe the board level SAS/SAS RAID functionality.
