Hi,

Here is my problem.  I have a Clariion CX500 connected to a Windows 2003
server that has a 2Tb filesystem.  I have 2 x LTO3 fiber drives that are
also directly connected to the windows server via the SAN.  The windows
server does not have anti virus installed or any third party apps.  When I
run a test backup on the C: of the server I get over 60MB/S throughput.
When I run a backup on the E: (which is SAN attached) I only get 25 MB/s.
The parallelism is set to 16 and 8 on each drive.  If someone knows why I
am only getting 25 MB/S and how I can increases this performance please
let me know.  These a flat files that are being backed up that have no i/o
on the them at the time of the tests.


Thanks

Raph
