server board (on-board SATA only), from installed add-in SAS/SATA RAID cards, or from an optionally
installed SAS expander card for drive configurations of greater than eight hard drives.
Power harness connector
– The backplane includes a 2x2 connector supplying power to the backplane.
Power is routed to each installed backplane via a multi-connector power cable harness from the server
board.

PCIe OCuLink* Connectors
The backplane has support for up to eight (8) NVMe SFF SSDs. The backside of
the backplane includes eight OCuLink* cable connectors, one for each drive connector on the front side of
the backplane. Each installed NVMe drive must have PCIe signals cabled to the appropriate backplane
OCuLink connector from any of the following PCIe signal sources:
Available onboard PCIe* OCuLink connectors on the server board
Optional PCIe 4 or 8 Port Switch Add-in Card
Optional Tri-Mode Raid Module or Add-in Card
Optional PCIe 4 port Retimer Add-in Card
See section 7.4 for NVMe support information.

8 x 2.5” Drive Dual Port SAS Backplane
This section applies to the 8 x 2.5” drive dual port SAS backplane (accessory kit iPC – A2U8X25S3DPDK).
With the 8 x drive dual port backplane accessory kit installed, the server can support up to eight dual port
SAS drives. The front side of the backplane includes 8 x 29-pin drive interface connectors, each capable of
supporting 12 Gb SAS or 6 Gb SAS/SATA. The connectors are numbered 0 through 7. Signals for each set of
four drive connectors (0-3 and 4-7), are routed to a pair of mini-SAS HD connectors on the back side of the
backplane, one for the primary port and one for the secondary port.
