Re: [Veritas-bu] Sun/StorageTek based LTO4 encryption

I am now using kms, and because the tape drive does the compression and
the tape drive does the encryption, I have not noticed any loss in
compression yet ( only have had it running for about 1 week) that was
something I was also concerned about. You have to compress before you
encrypt, and as far as I could find out the tape drive knows that.

I have also been looking at this as an option.
One of the considerations is the effect encryption has on compression.
I have heard you loose the ability to compress effectively when using
compression.
Have you noticed an effect on your tape drive compression when using
tape drive based encryption?

I have using the IBM LTO-4 drives with STK libraries, works great, as
long
the firmware is version 7BG2, I have seen the drive reset itself if the
firmware is any other version (more recent ones). Also using NBU & KMS.
It works good, note you can only have 2 volume pools that use
encryption.
