1. Am I potentially doubling the size of certain files in the stg pool by
running multiple compression algorithms.?
No - the drive logic won't compress already compressed data, so there's no
real risk of this.
2. By turning off DEVCLASS compression, is that effectively disabling
hardware compression performed by my tape device (IBM 3590 TAPE Device /
Cartridge)
Yes.
3. If client compression and hardware compression are turned on, and
hardware compression isn't really buying me anything... won't the attempt
at hardware compression prevent streaming? I think it
will.
Nope, not to the best of my knowledge. In fact, a pre-compressed data
stream is less likely to starve the drive.
I'm looking for YES/NO answers with a valid explanation. Anyone?????
