If using a managed network switch, verify the miSAN-V-Series is
synchronizing at 1000Base-T. If not, change the networking hardware.
Directly connect the miSAN-V-Series to the backup server.
Disable all virus scanning software on the backup server and the data source
machines.
b. SCSI Attached
Isolate the miSAN-V-Series as the only device on the SCSI bus.
Check the SCSI cable for any bent or damaged pins/connectors.
Verify you are using an Ultra 3 Wide SCSI (Ultra 160) or better SCSI HBA and
that the miSAN-V-Series is synchronizing at 160 MB/sec.
Verify that the manufacturer’s drivers are loaded for the SCSI HBA.
Disable all virus scanning software on the backup server and the data source
machines.
2. Slower than expected speeds from the miSAN-V-Series (copying virtual to physical
tape).
a. Make sure “Drive compression for copying” is enabled before copying from
virtual to physical tape (See “Drive compression for copying” on page 52).
Selecting this feature enables the built-in data compression (if available) for
the physical tape drive.
b. Check the SCSI cable for any bent or damaged pins/connectors.
c. Clean the tape drive, and then retry normal operation with a new, never-
before-used tape cartridge.
