Re: MagStar Tape Library #3575 vs. LTO
2001-02-08 19:06:37
The LTO roadmap includes two paths
Ultrium, which is the "LTO" that everyone here is talking about
and Accelis, which is the next generation 3570 tape, with the same shape and
size, emphasis on fast access to data and considerably higher capacity
I assume that when the accelis drives become available you'll be able to
field-upgrade your 3575 to them.
*BUT*
This is all marketing hype and there have been no announcements since the
original roadmap.
If you want to drool a bit, do a search on Accelis at www.ibm.com and there are
specs at www.lto.org
In the meantime you could set up a three level hierarchy
disk-> 3575 -> something slow
to get the best of both worlds

Hi LuAnn,
we are also in the exact same situation. We backup a large database and many
smaller filesystems. We also have and SP and L32 3575. My thoughts are this:
keep the magstar _and_ buy LTO. I plan to use LTO for the database backups (few
but large files) and my offsite storage pool. Then keep using the magstar for
the many, but smaller filesystem files.

We are reaching storage capacity limit in our current MagStar Tape Library.
We have TSM 3.7 (will upgrade to 4.1 later in the summer). Our TSM
environment is in an AIX environment. We have 6 RS/6000 AIX nodes on an SP
switch and about 30 NT servers that we back up nightly.
We are looking at upgrading or adding on to our existing library. One
option our vendor would like us to consider is the use of a LTO system. He
said that although it is not quite as fast our as MagStar the storage
capacity on the tapes are 100 gig native and 200 gig compressed. Does
anyone have any opinions on that?
Thanks.
