6.3 Hot-Swap Hard Drive Support

The Intel

Server System SR1695WB can support up to four hot-swap SATA or SAS hard

drives. Hard drives interface with the passive backplane through a blind mate connection

when drives are installed into a hard drive bay using hot-swap drive trays.

The passive backplane acts as an intermediate pass-through interface board where SATA

ports of the server board or add-in SAS/SATA controller are cabled to the backplane. The on

board Intel

82801Jx I/O Controller Hub provides the necessary drive interface. You can

also connect the passive backplane to an add-in PCI Express* based SAS/SATA RAID card.

The following sections describe the feature and connections between the backplane and

server board.
