Infiniband switches

Multiple switch options

We offer many different IB switch configurations, from eight-port standalone switches to 648-port behemoths to using multiple stacking 36-port switches in a fat tree topology (described below). We also offer InfiniBand in different subscription rates, and we’ll work with you to determine which speed is right for you. Rely on our experience in providing optimal solutions to your high performance computing needs.

Cost-effective approach to interconnecting large clusters

Using a fat tree topology is an effective way of holding down costs while not sacrificing bandwidth or latency. The key attribute of this non-blocking topology is that for any given level of the switch topology, the amount of bandwidth connected to the downstream compute nodes is identical to the amount of bandwidth connected to the upstream path used for interconnection. So when you compare the relative inexpensive cost of these 36-port top-of-the-rack switches to the modular chassis that support multiple line cards and spines, the amount of realized savings using this approach is often significant enough to allow for the purchase of additional computational power such as more nodes or better processors.

Subscription rates

With respect to subscription rates, not all applications require high bandwidth. In addition, many applications are limited by the number of processors on which they can run. In both of these instances, setting up an oversubscribed network makes sense, cutting down on the number of switches needed. So instead of a 1:1 non-blocking, full-bandwidth rate, you can consider a 2:1 or 3:1 oversubscribed network if your application warrants it.

Warranty information

Please note that our InfiniBand switches include manufacturer warranties, separate from the warranty service purchased for compute and head nodes. Should an issue arise, Advanced Clustering’s support team will work with you to get the issue resolved. There are multiple warranty options available.
