Assessing Read/Write Performance as a Function of Workload

Infiniband IPoIB datalink partition and IP interface configuration is easy and painless using the same network BUI page or CLI contexts as ethernet, says Fishworks blogger Cindi in her update on “Infiniband for Q3.2009.” Port GUID information is available for configured partitions on the network page, she continues, which makes it easy to add Sun Storage 7000 Unified Storage System HCA ports to a partition table on a subnet manager.

Aggregate up to 72 QDR 4x Ports into a Single 1RU Switch 

The Sun Datacenter InfiniBand Switch 72 joins the Sun Datacenter InfiniBand Switch 648 and Sun Datacenter InfiniBand Switch 36 in Sun’s third generation family of InfiniBand (IB) switches. The one rack unit (RU) switch is a complete, ultra-slim, ultra-dense switch fabric solution for Sun server clusters up to 72 Quad Data Rate (QDR) IB nodes. Most importantly, the switch integrates with the Sun Blade 6048 InfiniBand QDR Switched Network Express Module, scaling up to over 576 end nodes.

Self-contained, Multi-purpose 36-node, QDR InfiniBand Switch Fabric Solution

The Sun Datacenter InfiniBand Switch 36 is a 36-port Quad Data Rate (QDR) InfiniBand leaf switch enabling users to bind Sun Blade and Sun Fire servers and storage systems into a 36-node cluster. This multi-purpose switch can act as a self-contained fabric solution for smaller InfiniBand clusters or as a building block for hierarchical fabric topologies supporting larger clusters of Sun Blade or Sun Fire servers and storage systems.

High-density, QDR, Standards-based, Fully Non-blocking IB Core Switch

The Sun Datacenter InfiniBand Switch 648 is a high-density, Quad Data Rate (QDR) IB core switch that offers capacity for up to 648 servers and storage systems. It can replace up to 152 discrete switching elements and thousands of cables in large-scale solutions, Sun reports. It is an ideal solution for cluster sizes that range from 200 servers to 5000+ servers. This full industry standard Infiniband switching platform fits into a standard 19-inch rack. With an 11u height, up to three switches can be mounted in a single rack for 1,944 4x QDR InfiniBand ports in 33 rack units.
