RE: LTO3 VS Virtual Tape.

[ChadB@xxxxxxxxxxxxxxxxxxxx]

I did some basic testing when it was first available, and it's not speedy
by default unless you do the setup work that Lukas is describing (splitting
out another ask, spec'ing the right IO/arms, etc.).  Didn't LTO4 just come
out as an option?

You can't really compare a given tape drive to Virtual Tapes without
exactly specifying what kind of IO subsystem you have for your virtual
tapes.

It would make a lot of sense to separate the virtual tapes into their
own ASP, so your reads don't interfere with your writes.

Virtual tape speed is only limited by your IO subsystem aka buy more
disks, get more speed.

Subject: LTO3 VS Virtual Tape.

Has anyone done any performance comparisons between LTO3 Drives versus
Virtual tape?  I'm looking for some help with my shrinking backup
window.
