Ok, I
I'm wondering if there are filesystem fragmentation issues when using
devclass=file on an NFS mounted DD volume. Filesystem fragmentation is an
issue when using devclass=file on most filesystems that I'm aware of. How
long have you been running this way on the DD?

Ben,
First, thanks for sharing your experiences. Very enlightening.
I'm curious why you decided to use devclass=file volumes, instead of using
the DD580 as a VTL. It does have a VTL personality, doesn't it?

Most large organizations I work with have a Standard build for their
systems - the OS, applications, etc - so they only need to backup data (we
do that internally in IBM as well). Minimizes what needs to be backed up,
and makes deploying systems MUCH easier (1 DVD, just over an hour, all
set).

Charles,
You're statement about the SL8500 make me nervous. We are planning to
move to a configuration where we are sharing the SL8500 with our
mainframe. We will use ACSLS with a library manager and 3 clients, 16
LTO3 drives.
Are you having TSM issues? Or ACSLS
But the 3584 we have remotely is
bloody -fast-. Scary fast.
I flinch evertime I watch the robot in the 3584 and it moves to
the home frame. I keep thinking it's going to fail to stop and break
through the window.
