Why is Intel getting into the InfiniBand business? This is big news; bigger than the size of the acquisition would suggest.
Certainly it signals Intel’s growing interest in the infrastructure business. But perhaps more interesting is what it says about InfiniBand.
While InifiniBand is best known for HPC applications, I suspect Intel may have its sights on a much broader market than university labs. InfiniBand incorporates a number of technologies that make it very well suited for the enterprise.
Several current data center trends highlight why InfiniBand is well-positioned as the fabric of the future:
1) Server virtualization: To run a large number of VMs, virtualized servers need a lot of bandwidth. InfiniBand delivers by far the most cost-effective, power-efficient performance.
2) Convergence: The only solution for the growing connectivity needs of virtualized servers is to converge the infrastructure. It’s not hard to see the benefit of two cables vs 20 cables. InfiniBand provides the ideal transport for this. It is and always has been a reliable connection. You can run both Fibre Channel and Ethernet traffic over it without packet reordering.
3) Data Center Fabrics: The next challenge for the data center is to fix the East/West problem. Multiple Ethernet vendors are proposing solutions that simplify and accelerate server-to-server communications. Well, InfiniBand was designed as a fabric. The networking challenges faced by Ethernet were addressed in the original InfiniBand design.
Even the knock that InfiniBand is “just for HPC” is not true.
Xsigo has offered for years a data center fabric that converges FC + Ethernet server connections to a single InfiniBand link within the rack. The top-of-rack device fits right in with conventional data center core switching gear. It’s successfully deployed in hundreds of data centers today. And, Oracle uses InfiniBand as the cluster interconnect of their flagship database machine, Exadata.
Intel would probably not undertake a strategic move like this simply to better serve the HPC market. The big prize is the market for servers and infrastructure in next-generation cloud data centers.
Server virtualization dramatically altered the way we look at processors. The sky’s now the limit when it comes to multi-core / multi-socket implementations.
Infrastructure virtualization is the next big wave. Data center fabrics are the products riding that wave. Like virtualized servers, fabrics too will be built on significantly faster underpinnings. With an InfiniBand offering, Intel may be positioning themselves as a leader with a proven technology that was originally designed for exactly that application.
