The Definitive Report on 10G Ethernet Server Connectivity
The market for 10GbE server connectivity remains extremely dynamic with rapid shifts in technology and vendor market share. Evaluating the long-term outlook for adapter and controller vendors requires an in-depth understanding of their products and roadmaps. Now in its fifth edition, "A Guide to 10G Ethernet Controllers and Adapters" provides a uniquely detailed look at the vendors and products in this market. This report offers complete chapters on the leading 10GbE controller vendors. Because OEMs source both board-level and chip-level products, we include full coverage and comparisons for both 10GbE NICs and 10GbE controller chips. Covered applications include LAN-on-motherboard (LOM), standard adapters (NIC), blade-server mezzanine cards, and converged network adapters (CNA).
With the transition to 10GbE, many new technologies are being added to Ethernet-controller designs. Most of these new features are designed to offload processing from the host CPU and therefore increase throughput or lower CPU utilization. These offloads are divided into three basic categories: stateless offloads that work with traditional operating system stacks; stateful offloads such as TOE that require stack changes; and virtualization offloads for environments such as VMware and Xen. For converged networks, new protocols such as Fibre Channel over Ethernet (FCoE), iSCSI, and iWARP/RoCE (RDMA) also come into play. With all of this complexity, no single vendor can satisfy the requirements of all potential customers. We help you sort out which vendors meet your specific needs.
We Map Out the Crowded Vendor Landscape
"A Guide to 10G Ethernet Controllers and Adapters" begins with an extensive overview of this fast-growing market. The report provides tutorials that help you plow through the alphabet soup of acronyms and standards. We explore the market and technology trends for 10GbE and 40GbE server connections, followed by an explanation of the common attributes of these products.
Following these introductory chapters, the report delivers a complete chapter on six major vendors of 10GbE controller chips and NICs: Broadcom, Chelsio, Emulex, Intel, Mellanox, and QLogic. Each major-vendor chapter includes company background information, full details of announced products, product-roadmap information where available, and our conclusions about the vendor and its products. An additional chapter covers vendors that primarily sell adapters: Brocade, Myricom, and Solarflare. We then dedicate a chapter to detailed head-to-head comparisons of the many available controller, NIC, and CNA products.
The report concludes with our outlook for the server market for Ethernet and the leading vendors.
