StorageServicesP2

Background

New in this phase

• 8/31: perform simple load tests of gridftp-based storage on all sites w/ gridftp doors, and establish benchmarks. Capture this data and report on bencharks.
• 8/31: perform similar load tests with srm-managed storage
  • AGLT2
    • Wenjing Wu (wuwj@umich.edu) will coordinate for AGLT2 tests
    • Now I am carrying on the test of the IO rate of Local disk and raid system by using IOZONE
    • Additional tools: 'hdparm -tT', 'time dd if=/dev/zero of=/atlas/data08/dq2/test_io', 'bonnie++ ', etc.
  • BNL
  • MWT2_IU
  • MWT2_UC

Results

• No reported tests of local tranfers or file system performance.
• See LoadTestsP2 for results of memory-to-disk, and disk-to-disk load tests to NFS and dCache disks.
• Results indicate up to ~ 112 MB/s using Globus gridftp and up to 60 MB/s for dCache gridftp.
