• SR-IOV Capability: Up to 64 Virtual Functions (VFs) per port.

• Flexible Port Partitioning (FPP): Virtualization of physical ports into multiple logical paths with custom bandwidth constraints.

• Tunneling Offloads: VXLAN and NVGRE stateless offloads to preserve CPU cycles in virtualized overlays.

Performance Offloads

• Storage Over Ethernet: Supported protocols include native iSCSI, FCoE, and NFS.

• Stateless Offloads: TCP/UDP/IP Checksum Offload, Large Send Offload (LSO), Receive Side Scaling (RSS), and Transmit Segmentation Offload (TSO).

Electrical, Thermal & Physical Profiles

Power Consumption

The X550 architecture integrates the MAC and PHY into a single piece of silicon, significantly reducing thermal footprints compared to older X540 units:

Link Speed / Mode	Typical Power	Maximum Power
Dual-port 10 GbE	11.2 W	13.0 W
Dual-port 1 GbE	5.5 W	6.4 W
Dual-port 100 Mb/s	3.9 W	4.9 W

(Note: HPE 562T variants note an edge-case maximum board draw up to 15.56 W depending on active chassis cooling models).

Environmental & Physical

• Operating Temperature: 0°C to 55°C (32°F to 131°F)

• Storage Temperature: -40°C to 70°C (-40°F to 158°F)

• Dimensions: Roughly 167 mm x 69 mm (Standard MD2 Low-profile design length)

Operating System & Ecosystem Compatibility

Fully supported across almost all enterprise network architectures:

• Microsoft Windows Server: 2012, 2012 R2, 2016, 2019, 2022, 2025

• Linux: Red Hat Enterprise Linux (RHEL) 6/7/8/9, SUSE Linux Enterprise Server (SLES) 11/12/15, Ubuntu, Debian.
