Active Mid-plane with SAS /SAS RAID Support
The active mid-plane is used to provide SAS / SAS RAID support. It has integrated on to it an
Intel IOP80333 IO processor and an LSI* LSLSAS1068 3Gb/s SAS controller. Together they
provide support for up to six SAS drives in this chassis. By default, this mid-plane option
provides software RAID levels 0, 1, and 10 utilizing Intel
the installation of optional RAID enablement devices, the mid-plane can support hardware RAID
levels 0, 1, 5, 10, and 50. The mid-plane 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.

Active Midplane2 with SAS/SAS RAID Support
The active midplane2 is used to provide SAS/SAS RAID support. It has an integrated LSI
LSISAS1078 3 Gb/s RAID On-a-Chip (ROC) device. It provides support for up to eight SAS
drives in this system. By default, this midplane2 option provides software RAID levels 0, 1, and
®
10 and utilizes Intel
Embedded RAID Technology II. With the installation of optional RAID
enablement devices, the midplane2 can support hardware RAID levels 0, 1, 5, 6, 10, 50 and 60.
The midplane2 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.
