supports up to four 2.5-inch SAS hard drives or SSDs.
2.5-inch
(x4) SATA backplane
A
full-length SAS hard drive/SSD backplane with a backplane cable. It
supports up to four 2.5-inch SATA hard drives or SSDs.
2.5-inch
(x2) SATA and 2.5-inch (x2) PCIe backplane
A
full-length backplane with two backplane cables. It supports up to
two 2.5-inch SATA hard drives or SSDs and two 2.5-inch PCIe SSDs.
For information about populating drives in the bay, see the Hard drive
or SSD bay numbering.
1.8-inch (x12) SAS SSD backplane
A full-length SAS SSD backplane with two
backplane cables. It supports up to twelve 1.8-inch SAS SSDs.
NOTE: All drives
connect to the system board through the hard-drive or SSD backplane
cable connector.
The following table provides information about
connecting different backplane configurations to the respective connectors
on the system board and expander card.
