Midplane Options
The midplane is designed and used, along with that of the bridge board and hot-swap
backplane, to improve cable routing within the system. The midplane is the key system board of
the system. It serves as a primary interface between the server board, hot-swap backplane, and
control panel. Two midplanes are offered for this system: a passive SATA/SAS, and an active
SAS/SAS RAID.
7.2.1
Passive Midplane
The passive midplane is used as an interconnect, routing drive control signals from either the
on-board SATA ports of the server board or SAS/SATA ports from an add-in card to the hot-
swap backplane. The hard drive controller signals are cabled to the midplane, which then
routes the signals to the hot-swap backplane through two edge connectors that plug directly
into it.
