Are you running the latest Emulex driver? Make sure you are using the
latest driver and firmware, and especially using the Emulex EMC driver.
Once you have that done, use the HBAnywhere to setup the EMC parameters
(The release notes should show you how)

Emuex 10000-E and mcdata switches.  Yeah Navi agent is installed and
also access logix. Switches are zoned and there is only one HBA in the
server.

What type of HBA cards and what type of SAN switch do you have? Are you
running access-logix in Navisphere? Are the switches zoned? what speed
are the fibre hba's running at?

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
