Again, that is why I went with KMS, (kms is NOT MESO) it is application
managed encryption that tells the tape drive to do the encryption NOT
the media server, kms just has the keys on the master server and NB
talks
encryption?

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

Tal,
I can only speak of the IBM LTO4 tape drives, I assume the others are
the same.
IBM says that each block of data to be written to the tape is compressed
or not then encrypted. They do not compress blocks

Hi,
I have read others' reviews on MSEO-- from what I understand it will peg
the CPU and reduce throughput dramatically to high-speed drives.
Has anyone not seen that?
