How to choose a DL325 Gen12 network adapter

Rule 1

Match the cabling to the switch

Orders record the cable type with a tracking option: AOC P79630-B21 or DAC/ACC P79633-B21; BASE-T cards on RJ45 cable use P79633-B21, and no transceivers can be configured with it.

HPE: “Transceivers cannot be configured if P79633-B21 is selected.” (page 28)

Rule 2

Check the cooling

Networking cards used with active optical cables (AOC) need a lower ambient temperature than with DAC; HPE gives an AOC thermal matrix per card, chassis and processor wattage, and cards not in it are supported at 30°C with AOC.

HPE: “30 °C is the default ambient temperature. The lower the temperature, the higher the wattage processors or high-speed networking cards can be supported.” (page 26)

Rule 3

Mind the slot rules

Shared-NIC (NC-SI) and Wake-on-LAN work in rear OCP slots A and B and the front Primary OCP slot; the front Secondary OCP slot has Wake-on-LAN only.

HPE: “Both rear OCP slots (slot A and B) and Front Primary OCP (Box3 Bay3) support shared-NIC and WOL (Wake on LAN) functions. Front Secondary OCP (Box3 Bay1) only supports WOL without the shared-NIC function.” (page 12)

DL325 Gen12 adapter questions

How many network adapters can a DL325 Gen12 take?

The DL325 Gen12 takes network adapters in its two OCP 3.0 slots and in up to six PCIe 5.0 slots. Up to two rear PCIe 5.0 x16 slots: slot 2 full-height as default, slot 1 optional in full-height or low-profile; the GPU CTO server lists up to six; how many PCIe and OCP slots a configuration supports depends on the Smart Chassis config ID chosen.

Does the DL325 Gen12 have network ports built in?

No embedded network ports; networking comes from an OCP or stand-up card. CTO servers are configured with PCIe stand-up or OCP 3.0 adapters, including Ethernet and InfiniBand adapters and Fibre Channel HBAs.

What does “Listed in QuickSpecs version 13” mean?

It means the adapter is in version 13 of HPE's QuickSpecs for the DL325 Gen12, the edition this page is built from.

Which Fibre Channel HBAs does HPE list for the DL325 Gen12?

HPE lists QLogic 32Gb and 64Gb Fibre Channel HBAs and Emulex 32Gb and 64Gb SecureHBAs. HPE's QuickSpecs list 6 Fibre Channel HBAs for it, by model: SN1610Q, SN1620E, SN1700Q and SN1720E. They are in the Fibre Channel HBAs section of this page.

What if the adapter I need is out of stock?

Out of stock today does not mean unavailable: we can often source this part. Add it to a quote request and we reply with current pricing and availability. Every message, quotes included, is answered within 24 hours.
