Intel® PRO/1000 PT/PF Quad Port Bypass Server Adapters

The world’s first native PCI Express* Gigabit Ethernet Quad Port Bypass Server Adapters

with the Intel® 82571GB GbE Controller provide in-line server appliances, such as intrusion prevention servers, with high-performance, low-latency, in-line connectivity, and a bypass mode to help ensure business continuity.

Enterprises are growing more complex with data and voice convergence, collaboration over wide area networks (WANs), and dynamic Web services. To meet this challenge, information technology (IT) managers must be able to monitor, analyze, and optimize local area network (LAN) traffic to ensure quality of service, application service levels, and security. This has resulted in a proliferation of application-specific server appliances for real-time traffic analysis and inspection, data acceleration, and traffic shaping.

Application-specific server appliances are commonly built with standard server building blocks—often Intel® architecture blocks—and perform an application-specific function. These appliances are not typically in-line devices. Because they are not endpoints and do not process network data packets, the network sees them as “bump-in-the-wire” networking devices. Many of these appliances hang off a span or an expensive tap, allowing the traffic to be duplicated and sent to the server appliance for analysis.

Today, however, there is an increasing need for server appliances that can act in real time on network traffic to prevent problems, especially network intrusions, rather than just detect them. To do this, server appliances are being moved in line with the network traffic flow. Examples of server appliances that are now moving in line are the intrusion prevention server and the internal security gateway.
