4.1.1 2.5'' Drive Hot-Swap Backplane Overview
Depending on the number of hard disk drives supported by a given system SKU, a system can
be configured with 1, 2, or 3 eight drive backplanes. Each backplane is attached to the back of
the drive bay assembly. On the front side of each backplane are mounted eight hard disk drive
interface connectors (A), each providing both power and I/O signals to attached hard disk
drives.
