ConnectX-8 adapter cable routing

This section provides cable routing information for the ConnectX-8 InfiniBand adapter.

Note

Depending on the riser bracket, the cable routing might be slightly different from the following illustrations.

ConnectX-8 adapter cable routing in scenario 1

Scenario 1:

Table 1: The server is equipped with one processor and one ConnectX-8 adapter (cable 1).
Table 2: The server is equipped with two processors and two ConnectX-8 adapters (cable 1 and cable 2)

Table 1. One processor and one ConnectX-8 adapter
Configuration	Riser bracket	From ConnectX-8 adapter on:	To
Servers with Processor Neptune Air Module	Full-height Full-height + rear 2.5–inch drive	Slot 1	`1a` PCIe 9A `1b` PCIe 9B
Servers without Processor Neptune Air Module	Full-height Full-height + rear M.2 drive	Slot 1	`1a` PCIe 9A `1b` PCIe 9B

Table 2. Two processor and two ConnectX-8 adapters
Configuration	Riser bracket	From ConnectX-8 adapter on:	To
Servers with Processor Neptune Air Module	Full-height + full-height	Slot 1	`1a` PCIe 9A `1b` PCIe 9B
Servers with Processor Neptune Air Module	Full-height + full-height	Slot 3	`2a` PCIe 13A `2b` PCIe 13B
Servers without Processor Neptune Air Module	Full-height + low-profile	Slot 1	`1a` PCIe 9A `1b` PCIe 9B
Servers without Processor Neptune Air Module	Full-height + low-profile	Slot 3	`2a` PCIe 15A `2b` PCIe 15B
Server with Compute Complex Neptune Core Module (10x2.5-inch chassis)	Full-height + low-profile	Slot 1	`1a` PCIe 9A `1b` PCIe 9B
	Full-height + low-profile	Slot 3	`2a` PCIe 15A `2b` PCIe 15B

Scenario 2:

Table 3: The server is equipped with two processors and one ConnectX-8 adapter (cable 1).

Table 3. Two processors and one ConnectX-8 adapter
Configuration	Riser bracket	From ConnectX-8 adapter on:	To
Servers with Processor Neptune Air Module	Full-height + full-height	Slot 1	`1a` PCIe 13A `1b` PCIe 13B
	Full-height + full-height	Slot 3	`1a` PCIe 9A `1b` PCIe 9B
	Full-height + rear 2.5–inch drive	Slot 1	`1a` PCIe 13A `1b` PCIe 13B
	Full-height + low-profile +low-profile	Slot 1/2	`1a` PCIe 15A `1b` PCIe 15B
	Full-height + low-profile + M.2	Slot 1	`1a` PCIe 15A `1b` PCIe 15B
	Full-height + low-profile + M.2	Slot 2	`1a` PCIe 9A `1b` PCIe 9B
Servers without Processor Neptune Air Module	Full-height + low-profile + low-profile	Slot 3	`1a` PCIe 9A `1b` PCIe 9B

	Full-height + low-profile	Slot 1	`1a` PCIe 15A `1b` PCIe 15B
	Full-height + low-profile	Slot 3	`1a` PCIe 9A `1b` PCIe 9B
Server with Compute Complex Neptune Core Module (EDSFF chassis)	Low-profile	Slot 1	`1a` PCIe 15A `1b` PCIe 15B
	Full-height	Slot 1	`1a` PCIe 9A `1b` PCIe 9B
Server with Compute Complex Neptune Core Module (10x2.5-inch chassis)	Full-height (8x2.5-inch NVMe, 10xU.3 AnyBay)	Slot 1	`1a` PCIe 9A `1b` PCIe 9B
