Intel PRO/1000PT Dual Port Gigabit Server Adapter

The Intel PRO/1000 PT Dual Port Server Adapter is a PCI Express x4 network interface card that provides two independent Gigabit Ethernet ports for server and workstation use. Each port supports 10/100/1000BASE-T speeds with auto-negotiation, connecting via standard RJ-45 cabling. By consolidating two network connections onto a single expansion card, the PRO/1000 PT conserves PCIe slots in servers where expansion capacity is at a premium, while still providing the bandwidth and redundancy options that multi-homed server configurations require.

Built on Intel's well-established PRO/1000 platform, this adapter benefits from mature driver support across major operating systems including Windows Server, Linux distributions, and VMware ESXi. Intel Advanced Network Services enable features like adapter teaming, where both ports can be bonded together for increased throughput or configured for automatic failover so that network connectivity is maintained if one link goes down. The full-height retail form factor fits standard server and tower chassis, and the adapter is designed to balance network processing loads across multiple CPUs in multi-processor systems, reducing the overhead on any single processor and improving overall server responsiveness under heavy network traffic.
