What are the port specifications and cable support for HPE 864985-001?

Features two RJ-45 10GBASE-T ports supporting 10/100/1000/10000 Mbps half/full-duplex auto-negotiation. Uses Category 5e or better for 1GbE up to 100m; Cat 6A or better required for 10GbE up to 100m. Includes link/activity/speed LED indicators per port for troubleshooting.

Which workstations is the 864985-001 compatible with?

Optimized for HP Z6 G4 and Z8 G4 workstations with factory-tested fit for internal module slots. Ensures mechanical/electrical integration preserving airflow and system scalability for high-core CPUs and large memory configs.

What advanced networking features does it provide?

Includes IEEE 1588 Precision Time Stamping, 802.1AS, 9.5K jumbo frames, TCP/IP checksum offload, large send offload, PXE boot, IPv6, Intel I/O virtualization, and power savings via 802.3az EEE and DMAC coalescing.

What is the system interface and power draw?

PCI Express v2.1 x4 (operable in x1 with potential degradation), dimensions 5.1x2.7in (14.5x6.9cm), 11.2W typical power requirement. Operates 32-131°F (0-55°C) with robust construction for enterprise durability.

How does it benefit virtualization deployments?

Supports VMware NetQueue and Microsoft VMQ for optimized multi-VM networking, reducing host CPU utilization. Combined with low-latency design and offloads, it excels in workstation virtualization for CAD, simulation, and VDI scenarios.

What controller powers the adapter?

Intel Ethernet I210 Controller (per port basis in dual config) enables industry-leading throughput, near line-rate 40Gbps bi-directional potential, and features like Data Direct I/O for reduced latency in iSCSI/unified networking.
