How we tested

Our test rig consisted of a host server and the RAID DAS unit under test. The host configuration was:
  • Dell PowerEdge 6600

  • Quad Xeon processors

  • 3GB of DDR

  • Adaptec Fibre Card 9210LP

  • HP Smart Array 64X Controller

  • Windows Server 2003
Two file transfers were performed. One was a single large file and the other test a large number of small files the test files were as follows:

Large File Test
A 1,812,838,470 bytes (1.68GB) ZIP file that cannot be further compressed

Small File Test
A folder containing 4,567 files in 227 folders with a total size of 844,952,770 bytes (805MB). In each case the time taken to transfer the file to and from the Dell server from the RAID DAS unit under test was recorded and the throughput calculated.
