BackupExec 2010 w/ Win2k8 x64 and IBM TS3100 running slow
I recently installed BackupExec 2010 R2 in Windows 2008 x64 server.
I'm using TS3100 over SCSI/LVD connect (directly to the server, not storage)
My local storage is netapp fas2020, both server and storage ethernet is bonded to 2gbit.
HBA is HP(LSI) 2000 series SCSI320.
During product evaluation i tried the following configuration:
1. Backup from disk to tape
2. Backup from NDMP (over ethernet) to tape
Both tests shows the following results:
1. NDMP to tape never passed 1000mb/m
2. Disk to tape never passed 1500mb/m
I'm using Symantec drivers for the tape library, and Microsoft drivers for HBA.
block size is set to 512KB, Buffer is 1MB, buffer count is 32 and high water count is 30.
Backups through NDMP starts very slow, after a while it reaches a maximum speed of 1000mb/m
