RAZOR cluster at CSSB
Razor is a 35 ton, 1000-node IBM cluster e1350 powered by dual core AMD processors and using Gigabit Ethernet as the interconnect. Consuming ~230kW of electricity, it is capable of performing 8.5 trillion calculations per second. Water-chilled rack doors and datacenter layout customized for large-scale, high-density system allow us to keep it operational. Behind the computing environment that is presented to its users there are:
- Twenty racks that house the computer cluster. Four of them hold the core infrastructure (switches, storage and management systems), twelve are filled with compute nodes, and four empty racks are available for future expansion.
- Each compute node rack holds six BladeCenter chassis. Each chassis holds fourteen nodes. Each of the thousand compute nodes has two dual core 2.0GHz Opteron CPUs, 4Gb of RAM and two 73 Gb SCSI hard drives in RAID 1 configuration.
- Force10 e1200 and s50 switches provides connectivity
- Four front-end nodes provide the interface to the cluster.
- Eight storage nodes provide access to 20 TB of cluster file system (GPFS) that spans two DS4800 storage arrays.
The original configuration made it as #51 on Jun 2006 edition of Top500 list
Razor's blade count was further increased in January 2007 to the total of 1154 Opteron based LS20 blades (4616 cores total).
