DATA SHEET Gigabit Server Network Interface Cards— Copper and Fiber Key Benefits Tenfold Throughput Boost Cost-Effect, Scalable Migration Accelerate your Fast Ethernet server connection to 1000 Mbps. 3Com® gigabit server network interface cards (NICs) and switches give you room for future growth. 3Com gigabit server NICs also provide a cost-effective, instant performance boost over your existing Category 5 UTP copper cabling. The gigabit server NICs for Category 5 cabling support variable-speed autonegotiation, providing a scalable upgrade from Ethernet and Fast Ethernet without replacing your existing network infrastructure. Automated Link Failover Link aggregation and failover allow you to install multiple NIC connections, boosting server availability and bandwidth. Centralized Management Standards-compliant remote management—including WfM, DMI, PXE, EFI, and remote wake up—helps lower network administration time and total cost of ownership (TCO). Compatibility and Reliability Faster Throughput 64-bit 133 MHz PCI-X bus mastering and support for Jumbo Frames deliver faster transmissions with lower CPU utilization. 3Com gigabit server NICs are fully compliant with global Ethernet standards and backed by our Lifetime Limited warranty. Advanced Server Features Server-enhancing capabilities help maximize the availability, scalability, and fault tolerance of your businesscritical servers. Increase Network Performance and Availability with Gigabit Ethernet It’s frustrating enough that your employees face traffic jams on their way to the office. They shouldn’t have to deal with the aggravation of a congested network, too. Chances are, your enterprise LAN provides a vast array of network services— e-business transactions, database processing, group messaging, and Web hosting—to an ever-growing user group. But if your server link is limited to 100 Mbps, you’re risking an access bottleneck that slows down server access, restricts user bandwidth, and hurts overall productivity. Migrating to 1000 Mbps Gigabit Ethernet is a simple and cost-effective upgrade that significantly improves application and system performance across the network. If your future plans include organizational expansion, Gigabit Ethernet is a necessary investment. Best of all, with our gigabit server NICs— both copper and fiber versions—you get 3Com advanced server features that boost system performance, improve network manageability, improve link fault tolerance, and reduce application response times. 3 C O M ® G I G A B I T S E R V E R N E T W O R K I N T E R FA C E C A R D S — C O P P E R A N D F I B E R Features and Benefits End-to-End Gigabit Networking 3Com gigabit server NICs accelerate network performance to 1000 Mbps. Like our 10/100 Mbps server NICs, our 1000 Mbps NICs are built to industry standards so they’ll work seamlessly with your Fast Ethernet hardware and cabling*. Designed for enterprise servers and backbones, they deliver outstanding throughput, renowned reliability, and timesaving management capabilities. 3Com Gigabit Ethernet solutions include NICs and switches, over copper or fiber cabling. Get in-depth information about our end-to-end Gigabit solutions, by visiting www.3com.com. Processing Offloads These server NICs offload cycle-intensive processing, reducing the burden imposed on the host CPU by TCP/UDP/ IP checksum and TCP segmentation tasks. They’ll help your server perform better and last longer. Faster, More Reliable Transmissions High-performance capabilities include 64-bit 133 MHz PCI-X bus mastering, interrupt coalescence, Jumbo Frames, Microsoft large send, deep packet buffer, and flow control. These features help speed data transmissions through the server, with fewer errors and lost packets. Copper vs. Fiber 3Com’s family of gigabit server NICs deliver the fastest throughput available, standardsbased compatibility, and innovative management support. But which version, copper or fiber, is the right choice for your enterprise? Gigabit Over Copper The simplest and most cost-conscience way to migrate to Gigabit Ethernet is by installing a 3Com gigabit server NIC. This multi-speed, autonegotiating NIC lets you keep your existing Category 5 UTP backbone. The only other hardware you’ll need to modify is the backbone switch. 3Com SuperStack® 3 Switch 3300, for example, is easily upgraded with a simple gigabit plug-in module. Or upgrade to a gigabit-ready SuperStack 3 Switch 4900. Gigabit Over Fiber Building a fiber-optic backbone is a bigger investment because it requires special switches and cabling, but the rewards are numerous. Fiber cabling is highly resistant to electromagnetic interference, packet snooping/ sniffing, and signal degradation—making it ideal for longer cabling distances, high-security LANs, and electrically “noisy” environments. For growing companies, consider this—fiber optic cabling supports unlimited throughput (copper cabling’s limit is 1000 Mbps). You’ll have room to grow your business, and plenty of bandwidth when the 10-Gigabit Ethernet technologies arrive. offline; PCI 2.2-compatible remote wake up over the bus; and PCI-X for a wider, faster data path. Centralized Management for Lower TCO Advanced Server Performance 3Com gigabit server NICs include innovative features designed to optimize server performance and bandwidth: • Link Aggregation lets you install multiple NICs in a single server for increased throughput, automatic link failover, and maximum availability. • Bidirectional load balancing distributes data traffic across multiple NICs and switches. • Support for multiple VLANs lets your security administrators monitor and secure traffic streams— without relying on traffic-slowing router hops. • Advanced PCI-bus support includes PCI Hot-Plug, which lets you hotswap NICs without taking the server 2 Standards-based remote management helps reduce the single biggest cost of running your LAN—configuring and troubleshooting all those PCs. Centrally controlled capabilities—such as remote wake up, DMI, and SNMP MIB—help you manage networked systems without having to physically visit each machine. It saves your precious time as well as some big TCO expenses. Choose 3Com for Effortless Connections 3Com has the most experience in delivering network connections that access your network’s increasingly complex infrastructure. Reliable, open standards-based 3Com server NICs work within your existing environments to help ensure network availability and high-speed performance, while lowering your TCO. 3 C O M ® G I G A B I T S E R V E R N E T W O R K I N T E R FA C E C A R D S — C O P P E R A N D F I B E R Features and Benefits 3Com Service and Support 3Com offers the support options you need—anytime, anywhere.
