Intel EXPI9404PTLBLK PRO/1000 PT 4-Port Low Profile PCI-E Server Adapter, Bulk

The dedicated I/O bandwidth of PCIe ensures priority performance on each port, without bus sharing, for Gigabit Ethernet connectivity in Category-5 networks. The Intel PRO/1000 PT Quad Port LP Server Adapter improves performance in multi-processor systems by balancing network loads across multiple central processing units (CPUs). Additionally, the Intel PRO/1000 PT Quad Port LP Server Adapter supports Intel® I/O Acceleration Technology (Intel® I/OAT) for faster I/O processing on the new Intel® Xeon® processor-based servers.
Load balancing: Increases performance on multi-processor systems by efficiently balancing network loads across CPU cores when used with Receive-Side Scaling from Microsoft or Scalable I/O on Linux
Intel® I/O Acceleration Technology (Intel® I/OAT): Accelerates I/O with higher throughput and lower CPU utilization by offloading processing overhead.
Compatible with x4, x8, and x16 full-height PCI Express slots: Allows quad-port operation in almost any PCI Express server slot, except x1 slots, and allows each port to operate without interfering with the other
Support for most network operating systems (NOS)
