LTO-3 Hardware/Software Compression
Hi guys,
INFO:
Server: HP DL180 G6
TapeDrive: HP StorageWorks Ultrium 920 SAS
Software: Windows Server 2012 R2 / Backup Exec 15
Problem:
LTO-3 Tapes only have 400GB uncomp...
Haven't seen anything outlining that LTO3 can't do hardware compression, and the easiest way to test this is to download HP Library and Tape Tools, stop the BE services and run the compression test. This will tell you whether or not the drive can do this.
We used to get HW compression on 1/8 G2 autoloaders when doing this test on LTO3-based drives with no hassles.
It might be that your data is expanding if it is already compressed which would result in less space being used on a tape.
Thanks!
