Dual-Port 10Gb Adapter for HPE Servers

This HPE 544M adapter adds two 10GBase-X ports through a single PCI Express x8 slot. It suits administrators upgrading rack-mounted HPE systems that need extra bandwidth for storage or cluster traffic. The card is new and carries REACH and RoHS environmental certifications.

PCI Express x8 Host Interface

The card requires a physical x8 PCI Express slot that can negotiate at least x8 electrical width. A shorter x4 or x1 slot will not provide the lanes this adapter expects, so the server board must expose a full-length x8 connector. Verify the slot layout in the server manual before ordering.

Plug-In Card Installation

The adapter follows a standard plug-in card form factor measuring 8.5 inches wide by 7 inches tall, so it fits full-height brackets in 2U and larger chassis. Low-profile or half-height servers cannot accommodate the bracket height. Driver support must be added through the operating system or HPE firmware repository after the card is seated.

Questions about this item

What does the 10 Gb/s speed rating mean when the 544M is installed in a server?

Each port runs at 10 Gb/s using 10GBase-X signalling, so the adapter provides two independent 10 Gb/s links for InfiniBand QDR or Ethernet traffic.

What does the PCI Express x8 interface limit in practice?

The x8 host interface supplies enough lane bandwidth for both 10 Gb/s ports to operate at line rate simultaneously.

What physical space does the plug-in card need to fit?

The card measures 8.5 inches wide, 7 inches tall and 3 inches deep, so it requires a full-height PCIe x8 slot with that much clearance.
