Anyone have a particularly large HSM environment and been using it a while?
I'm curious on any experiences with the product, good or bad. I would
imagine there must be some people out there who need long term storage of
infrequently accessed files and have considered it as a solution for that.

Hi,

I have one customer that may fall into the large HSM category.  They
have a document management program that is based around HSM.  The last
time I did an update to the server they had about 6 Million documents
each of which contains a few to many different files.  They have about
500GB of local storage for the stub files and local cacheing and are
using several 3995 Optical libraries to migrate the data to.

I also work with a different customer that has a similar environment but
it is not as large.  They are only managing about 2.5 to 3 million files
and require only one 3995 library with just over 1 TB of data.

Both of these system work really well.  Performance is very good.  In
fact one of the customers has a requisite to be able to produce any one
of the millions of documents on the screen in under 3 minutes!  That
time includes doing the search thru the application database to
determine the needed files, issuing the recall from ITSM server, loading
the Optical platter, transmitting the data, assemble it and display it
on the screen!  I was quite impressed with how well it handles that.

Like any product it has its quirks but for the most part once it is set
up it just works!

If you have any specific questions or need help with your environment
please feel free to contact me.
