CPU and bulk storage purchase 2009

Updated on Wed, 2009-06-17 10:14 by testadmin. Originally created by jeromel on 2009-06-17 09:47.

The assumed CPU profile will be:

  • 2 GB of memory per core
  • Nearly 6 TB of disk space per node
  • Several CPU model will be investigated for best price/performance ratio (bulk purchase pricing matters in this purchase hence coordination between STAR/Phenix is likely needed) - currentely being considered are
    • Xeon 5550 @ 3350 SI2k (scenario A)
    • Xeon 5560 @ 3526 SI2k (scenario B)

The share between space and CPU is as below within the following caveats:

  • THe additional massive amount of storage (+170 TB for production) requires a secondary Titan head and the proper network switches. The total cost is projected to be ~  50k$ and we agreed to leave a ~ 20k$ unspent fund to move in this direction (cost shared with facility budget)
