Intel® Server System SR2500AL 

New to this generation of high density server platform is the concept of the mid-plane. The mid-
plane is the interconnect between the server board and both the hot-swap backplane and 
control panel. It is also used to determine which hard drive technology is to be supported.  Two 
different Mid-plane options are available for this platform 1) a passive mid-plane capable of 
supporting SATA ports from the server board or SAS using ports from an add-in card; 2) an 
active SAS / SAS RAID mid-plane.  This section will describe the hard drive interface support of 
each of the mid-plane boards. 

The passive mid-plane is used as an interconnect, routing drive control signals from either the 
on-board SATA ports of the baseboard or SAS/SATA ports from an add-in card to the hot-swap 
backplane. The hard drive controller signals are cabled to the mid-plane which then routes the 
signals to the hot-swap backplane through two edge connectors that plug directly into it. See 
Table 22. Mid-plane-to-Backplane Card Edge Connector #1 Pin-out and Table 23. Mid-plane-to-
Backplane Card Edge Connector #2 Pin-out.
