Intel® PRO/1000 PT Quad Port Server Adapter Conserve valuable PCI Express (PCIe*) server slots while adding multi-port Gigabit Ethernet capability with the Intel® PRO/1000 PF 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 fiber optic networks.
The Intel PRO/1000 PF Quad Port Server Adapter improves performance in multi-processor systems by balancing network loads across multiple central processing units (CPUs). Additionally, the Intel PRO/1000 PF Quad Port Server Adapter enables Intel® I/O Acceleration Technology (Intel® I/OAT)2 for faster I/O processing on the new Intel® Xeon® processor-based servers

Features and benefits
Feature Benefit
Two Intel® 82571GB 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 integrated, dual port PCI Express Gigabit Ethernet controller chips
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*
Intel® I/OAT 2 Accelerates I/O with higher throughput and lower CPU utilization by offloading processing overhead
Virtualization Multi-port cards provide the platform with the port density required for virtualized environments
LC connectors Small connector design is compatible with the latest fiber-optic cabling standards
1000BASE-SX multi-mode fiber Ensures compatibility with fiber-optic cable lengths up to 275 meters
Support for most network operating systems (NOS) Enables widespread deployment
Remote management support Reduces support costs with remote management based on industry-wide standards
RoHS compliant 3, lead-free1technology Compliant with the European Union directive (effective as of July 2006) to reduce the use of hazardous materials
Intel® PROSet Utility for Windows* Provides point-and-click power over individual adapters, advanced adapter features, connection teaming, and Device Manager virtual local area network (VLAN) configuration
Advanced cable diagnostics Dynamically tests and reports network problems (error rate, cable length) and automatically compensates for cable issues
(cross-over cable, wrong pin-out/polarity)
Intel backing Backed by an Intel® limited lifetime warranty, 90-day money-back guarantee (U.S. and Canada), and worldwide support

1 Lead has not been intentionally added, but lead may still exist as an impurity below 1000 ppm, or an approved RoHS exemption applies.
2 Intel® I/O Acceleration Technology (Intel® I/OAT) requires an operating system that supports Intel I/OAT.
3 Lead and other materials banned in RoHS Directive are either (1) below all applicable substance thresholds as proposed by the EU and China, or (2) an approved/pending exemption applies.
