Mellanox ConnectX Ethernet – I/O Consolidation for the Data Center

10 Gigabit Ethernet, Data Center, Enterprise, Virtualization

Today’s data center requires a low-cost, low-power I/O solution with network flexibility to provide I/O consolidation on a single adapter. Network administrators want the best performance, scalability, latency while solving all their LAN, SAN and IPC (Clustering) needs packed into one adapter card in a virtualized or data center environment.

ConnectX® is a single chip solution from Mellanox that provides these features for the Data Center I/O unification with its hardware and software capabilities.  ConnectX® EN 10 Gigabit Ethernet drivers provide seamless connectivity by providing optimized 10 Gigabit Ethernet I/O services that easily scale with multi-core CPUs and virtualized servers and storage architectures.

Mellanox entry into the 10GigE landscape was rather late if you consider 10GigE started showing up in 2001 on servers as PCI-X followed by PCIe adapters. With Mellanox’s extensive experience in high-performance computing and broad range of industry relationships, it has forged ahead with this technology and was the first company to offer 10GigE with PCIe 2.0. Along the way, our products have matured to become the market-leader for performance, latency, as well as consolidating all data center networking onto a single adapter.

In a span of less than 2 years, Mellanox has introduced a broad range of products supporting various media interconnects and cabling options including UTP, CX4 for copper and SR, LR and LRM for fiber optics.

Technology leadership in networking requires that a company not only have the best hardware solution, but compliment this with the best software solution to make a winning combination.

In my experience, working at other early startups, as well as network technology bellwether 10Gigabit Ethernet companies, the Gen1/Gen2 10GigE products introduced lacked the vision of what the end-customer requirements were. The products were a “mish-mosh” of features addressing 10GigE for LAN, clustering (iWARP), TCP acceleration (aka TOE) and iSCSI acceleration. They missed the mark by not solving the pain-points of a data center, be it blazing performance, low-latency, CPU utilization or true I/O consolidation.

Mellanox took the holistic approach to data center networking with a deep understanding from its InfiniBand leadership and knowledgebase, server and system configuration, virtualization requirements and benefits, driver software requirements, and most importantly, understanding customer requirements for each vertical segment.

Today, ConnectX® EN 10 Gigabit Ethernet drivers support a broad array of major operating systems, including Windows, Linux, VMware Infrastructure, Citrix XenServer and FreeBSD.

The ConnectX® EN 10 Gigabit Ethernet drivers provide:

– All Stateless offload features
– Virtualized accelerations
– Data Center Ethernet (DCE) support
– FCoE with full hardware offload for SAN consolidation on 10GigE
– Lowest 10GigE (TCP/IP) latency comparable to expensive iWARP solutions
– Single Root – IO Virtualization (SR-IOV) for superior virtualization performance
– Linux Kernel and Linux Distribution support
– WHQL certified drivers for Windows Server 2003 and 2008
– VMware Ready certification for VMware Virtual Infrastructure (ESX 3.5)
– XenServer 4.1 inbox support
– Line-rate performance with very low CPU utilization
– Replace multiple GigE NICs with a single ConnectX Ethernet adapter

To complete the last piece of the puzzle, i.e. IPC (clustering) for the Data Center, I’ll soon post in my blog on Industry’s Low Latency Ethernet (LLE) initiative and its advantages compared to current available clustering solutions on 10GigE.
