SAS/SATA Midplanes
The midplane serves as the primary interface between the server board, the hot-swap
backplane, and the control panel. Two midplanes are offered for this system:
• Passive SATA/SAS
• Active SAS/SAS RAID.
Passive Midplane
The passive midplane s 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 following diagram show the location for each connector
found on the passive midplane.
