Hard-drive or SSD backplane

Table 1. Hard-drive or SSD backplane configurationsThis table describes all the hard drive or SSD backplane configurations available on M830.
Backplane	Configuration
2.5-inch (x4) SAS backplane	A full-length SAS hard drive/SSD backplane with a backplane cable. It supports up to four 2.5-inch SAS hard drives or SSDs.
2.5-inch (x4) SAS backplane
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.

Table 2. Hard-drive or SSD backplane configurationsThis table describes all the hard drive or SSD backplane configurations available.
Drive backplane configurations		Connectors
Drive backplane configurations		SATA_BP connector on the system board	J_PERC connector on the system board
2.5-inch (x4) SAS backplane		-	SAS backplane cable connector that connects four hard drives or SSDs to the system board.
2.5 -inch (x4) SATA backplane		SATA backplane cable connector that connects four hard drives or SSDs to the system board.	-
2.5-inch (x2) SATA and 2.5-inch (x2) PCIe backplane		SATA drive backplane cable connector that connects two hard drives or SSDs to the system board.	PCIe drive backplane cable connector that connects two PCIe SSDs to the system board.
1.8-inch (x12) SAS SSD backplane		SAS drive backplane cable connector that connects SSDs populated in bays 6–11 to the system board.	SAS backplane cable connector that connects SSDs populated in bays 0-5 to the system board through an expander card. For more information about installing an expander card, see the Expander card section.

NOTE: Ensure that you install the expander card on the system board if you are using 1.8-inch (x12) SSD system. For information about the installation procedure, see the Expander card section.

NOTE: For more information about hard drive or SSD bay numbering, see the Hard drive or SSD bay numbering.

NOTE: To locate SATA_BP and J_PERC connectors on the system board, see the System board connectors section.
