Dual-port server adapter for System x

This IBM PRO/1000 PT network card adds two Gigabit Ethernet ports to a server using a PCI Express x4 slot. It is built for administrators who need reliable wired connectivity on IBM System x platforms. The dual-port design supports link aggregation or separate networks without occupying an additional slot.

PCI Express x4 host interface

The card requires an available PCI Express x4 connection on the motherboard. Compatibility depends on the server providing that physical and electrical interface. Systems limited to x1 or x8 slots with different keying will not accept this adapter.

Intel IOAT offload included

Intel I/O Acceleration Technology moves network processing tasks from the main CPU to the adapter. This reduces host overhead during high-throughput workloads such as file serving or virtualization traffic. The feature operates automatically once the appropriate driver is loaded.

Questions about this item

What throughput does the 10/100/1000Base-T rating actually deliver in a server?

The adapter negotiates 10, 100 or 1000 Mbps per port over twisted-pair cable, giving up to one gigabit per second on each of the two RJ-45 connections.

How does the PCI Express x4 host interface affect bandwidth?

The x4 lane link provides enough PCIe throughput for both gigabit ports to run at line rate simultaneously without saturating the bus.

Will the 2.6 by 5.1 inch plug-in card fit a standard low-profile server slot?

The card measures 2.6 inches tall and 5.1 inches long with a 700 mil thickness, matching a typical full-height PCIe bracket; verify your chassis clearance before installing.
