This is for a customer who wants to run a benchmark today. Wish we had a JackRabbit in the lab, but our engineering machine is at a customer site.
One “blade” of a “CX1” with 3.2 GHz Nehalem’s, 24 GB ram (about to bump this to 72 GB for customer benchmark), an SDR Infiniband connection (1GB/s max).
DeltaV3 (ΔV3) with an 8 disk RAID6 (6 data drives, maximum read speed of about 660 MB/s), and a 6 disk RAID10 (not being used for this test). Infiniband SDR connection (1GB/s max).
A Cisco 24 port SDR switch (our engineering lab switch)
