Midplane Connectors
The enclosure midplane supports 24 2.5" SSD drive connections. It contains the SAS drive SFF-8680
connectors and the drive and enclosure status LEDs. These LEDs are made visible on the front of the
enclosure via light pipes / fiber optics. The midplane also contains two redundant Vital Product Data (VPD)
EEPROMS as required by the SBB specification. This midplane has been designed with stub elimination
(back-drilling) to reduce high-speed signal losses. It is mounted to the drive cage as shown in the following
image.
