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.
Note: Also known as EXPI9404VT
|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.|
||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*|
||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|
|IEEE standards/network topology
||10BASE-T, 100BASE-TX, 1000BASE-T|
