Intel® Gigabit VT Quad Port Server Adapter
Features and specifications

Note This adapter is sold and supported by Original Equipment Manufacturers (OEM). For technical support and driver downloads, you should contact the seller that provided your network adapter.

Overview
Conserve valuable PCI Express (PCIe*) server slots while adding four ports of Gigabit Ethernet capability with the Intel® Gigabit VT Quad Port Server Adapter. The dedicated input/output (I/O) bandwidth of PCIe ensures priority performance on each port — without bus sharing — for Gigabit Ethernet connectivity in Category-5 networks, as well as a low-profile design, which improves server throughput and rack density at the same time.

Intel Gigabit VT Quad Port Server Adapters are optimized for virtualized environments, supporting multiple queues, alleviating I/O bottlenecks between virtual machines. Additionally, the Intel Gigabit VT Quad Port Server Adapter enables Intel® I/O Acceleration Technology1 (Intel® I/OAT) with support for Intel® QuickData for faster I/O processing on the new Quad-Core and Dual-Core Intel® Xeon® processor-based servers.

The Intel Gigabit VT Quad Port Server Adapter represents the seventh generation of Intel® Network Adapters for Gigabit Ethernet, and features 10/100/1000 Mbps self-configuration for compatibility with mixed-speed network infrastructures.

Features

Feature Benefit
Two Intel® 82575GB Gigabit Controllers Enables four Gigabit Ethernet connections on a single adapter, delivering increased bandwidth for slot-constrained servers and providing high performance, reliability, and low-power use in two single, integrated, dual port PCI Express Gigabit Ethernet controller chips.
Low-profile Enables higher bandwidth and throughput from standard and low-profile PCIe slots and servers
Load balancing on multiple CPUs 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*
Interrupt moderation Delivers increased performance while significantly reducing CPU utilization.
Compatible with x4, x8, and x16 standard and low-profile
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
Remote management support Reduces support costs with remote management based on industry-wide standards
Category-5 unshielded twisted pair (UTP), 4-pair cabling Uses existing 4-pair cabling and saves re-wiring costs
RoHS compliant2, lead-free3 technology Compliant with the European Union directive (effective as of July 2006) to reduce the use of hazardous materials
Virtual Machine Device Queues (VMDq)4 In a virtualized environment, packets dedicated to different virtual machines can be routed to different queues, thus easing the routing of these packets to the target machine
Advanced packet filtering (per port) • 16 exact-matched packets (unicast or multicast)
• 4096-bit hash filter for multicast frames
• Promiscuous (unicast and multicast) transfer mode support
• Optional filtering of invalid frames
Direct Cache Access (DCA) The I/O device activates a pre-fetch engine in the CPU that loads the data into the CPU cache ahead of time, before use, eliminating cache misses and reducing CPU load
