I have 3 HP StorageWorks ULTRIUM 460 (LTO2) tape drives connected in a V880
Sun Fire server running Solaris 8.
Each tape drive has a SG-XPCI2SCSI-LM320 controller card.
The problem is that the performance is very bad!!
The tape drives are writing at 37GB/h (10MB/s) in compress mode.
The specifications for these tape drives are 210MB/s (60MB/s) in compress
mode.
I have used the ufsdump:
ufsdump 0f /dev/rmt/1cn <filesystem>
Has somebody some experience about it, please?
Thank you.
EDSON
