InfiniBand might be the obvious choice in the HPC world, but compared to the well-known and widely-used Ethernet standard, the comfort level of InfiniBand might be equated to sleeping on a bed of nails. IT executives, network administrators, server vendors, and managed service providers around the world understand Ethernet. They can integrate and update an Ethernet installation within an existing infrastructure, without specialized gateways. They know how to manage it and how to benchmark it. They know what to do if something goes wrong. When it comes to Ethernet, familiarity breeds peace of mind.
With costs going up, power at a premium, and manageability critical, it's no surprise that converging and consolidating have become central themes in networking. Converged voice and data networks are becoming pervasive. Fibre Channel over Ethernet (FCoE) will merge storage and standard network applications on a common infrastructure. Virtualization is fast becoming a critical technology to support server and storage consolidation in the datacenter.
When it comes to reducing capital and operating expenses, one infrastructure is simply better than two -- or more -- and the HPC environment is no exception. High-performance computing clusters that use an InfiniBand interconnect also use Ethernet. Ethernet is necessary for user and storage connectivity, and for the management network that orchestrates the cluster. Replacing the InfiniBand interconnect with 10GE to create a single, all-inclusive infrastructure will cut hardware and power costs, and simplify manageability. And, that infrastructure combines high performance with low power needs and a sufficiently low latency for many HPC applications, making it an excellent fit for technical and budget requirements.
