HPE ProLiant DL345 Gen11 Networking Adapters
Genuine HPE network adapters for the HPE ProLiant DL345 Gen11, new and refurbished. The platform has no embedded networking — every build picks either an OCP 3.0 card or a stand-up PCIe adapter as its primary networking, then adds optional cards from there.
DL345 Gen11 Networking Specifications
- Form factors: two OCP 3.0 slots at PCIe 5.0 x8, plus PCIe 5.0 x16 stand-up slots on the primary and secondary risers
- Speeds: 1GbE BASE-T, 10GbE BASE-T and SFP+, 10/25GbE SFP28, 100GbE QSFP112, QSFP56 and QSFP28, and a 200Gb Slingshot SA210S PCIe NIC
- Silicon: HPE-qualified Broadcom, Intel, Mellanox, and NVIDIA adapters, most offered in both PCIe and OCP 3.0 versions
- OCP bandwidth: the OCP1 Upgrade Cable Kit supports PCIe x16 bandwidth at OCP slot 21, and is required for the Broadcom BCM57504 4-port SFP28 and the Intel E810 100GbE QSFP28 OCP3 adapters
- Cooling: 100/200 Gigabit Ethernet adapters require the Performance Fan kit
- Cabling: Direct Attach Cables for copper, or transceivers and cables for fiber, are purchased separately
Order networking with the server. The DL345 Gen11 has no embedded networking, so every build needs an OCP 3.0 card or a stand-up PCIe adapter. Both OCP 3.0 slots run at PCIe 5.0 x8, and x16 bandwidth at OCP slot 21 requires the OCP1 Upgrade Cable Kit.
Which network adapter fits the DL345 Gen11?
| Speed | Media | Form factors |
|---|---|---|
| 1GbE | 4-port RJ-45 BASE-T | OCP 3.0 or PCIe |
| 10GbE | 2-port BASE-T or SFP+ | OCP 3.0 or PCIe |
| 10/25GbE | 2-port and 4-port SFP28 | OCP 3.0 or PCIe |
| 100GbE | 2-port QSFP112 or QSFP28 | OCP 3.0 or PCIe |
| 200Gb | 1-port Slingshot SA210S | PCIe |
A few options are PCIe only, including the Mellanox 100Gb 2-port QSFP56 adapter and the NVIDIA 100Gb 2-port NVMe-oF Offload Adapter. Every speed from 1GbE to 100GbE has an OCP 3.0 option, which is what keeps the two default PCIe slots free for storage.
Choosing the Right DL345 Gen11 Network Adapter
- Use the OCP slots first: the default riser configuration gives you two PCIe 5.0 x16 slots (four with the 4PCIe enablement kit, six with the 6PCIe kit), and storage controllers compete for them.
- Check the OCP1 upgrade cable: both OCP 3.0 slots run at PCIe 5.0 x8, and x16 bandwidth at OCP slot 21 requires that kit — which the QuickSpecs name for the BCM57504 4-port SFP28 and the Intel E810 100GbE QSFP28 OCP3 adapter.
- Plan cooling with speed: 100/200 Gigabit Ethernet adapters require the Performance Fan kit.
- Order optics separately: DAC cables and fiber transceivers are not included with the adapter, and BASE-T cards use standard copper patch cables.

DL345 Gen11 Networking Adapters FAQ
Does the HPE ProLiant DL345 Gen11 have built-in Ethernet ports?
No. The QuickSpecs list network ports as none and note 'No embedded networking'. Networking comes from the two OCP 3.0 slots or from stand-up PCIe adapters. The dedicated 1Gb iLO management port is separate.
How fast are the OCP 3.0 slots in the DL345 Gen11?
The QuickSpecs list both OCP 3.0 slots as PCIe 5.0 x8. The OCP1 Upgrade Cable Kit supports PCIe x16 bandwidth at OCP slot 21.
Which adapters require the OCP1 upgrade cable kit?
The QuickSpecs name the OCP InfiniBand network adapters, the Broadcom BCM57504 10/25GbE 4-port SFP28 OCP3 adapter, and the Intel E810 100GbE 2-port QSFP28 OCP3 adapter.
Do 100GbE adapters need extra cooling in the DL345 Gen11?
Yes. The networking notes state that 100/200 Gigabit Ethernet adapters require the Performance Fan kit.
Do SFP28 and QSFP adapters include transceivers?
No. Direct Attach Cables for copper environments, or fiber transceivers and cables for fiber-optic environments, must be purchased separately.
Can I mix Broadcom, Intel and Mellanox adapters in one DL345 Gen11?
Yes. All are HPE-qualified for this platform and appear in both the PCIe and OCP 3.0 lists. A common build pairs an OCP adapter for primary networking with a PCIe card for storage or high-speed traffic.
