Mass Storage (Disk) Backplane
Internal mass storage connections to disks are routed on the mass storage backplane, having connectors and
termination logic. All hard disks are hot-plug while removable media disks are not hot-plug. The HP Integrity
rx8620 Server accommodates two internal, removable media devices. Therefore, power connectors for a
removable media device are required on the mass storage backplane. For more information, refer to
Figure 1-12.
