alternatives to EMC DiskXtender

| Hi all,
I am new to ILM & HSM. Right now I am looking for a archival solution.
Looking thru EMC's website, Centera CAS & DiskXtender caught my eyes.
Although one is hardware and the other is software, it seems that the
roles of Centera CAS & DiskXtender overlapped. Both seems to have the
intelligence of organising objects with policies. Is somebody able to
explain this distinction between the two.
Also, is there any other good products out there that is able function
the role of DiskXtender?
Thanks to all.

| Actually they are very different.
Centera is a storage platform based on 'CAS' - Content Addressed
Storage. Centera doesn't support traditional protocols (i.e.
NFS/CIFS/WebDAV/FTP etc. It only talks it's own API.
DX is software that provides a file system front end to Centera (and
other devices) with HSM.
Would love to chat - I used to be at EMC (was 'The Centera Guy') and am
now with StorageSwitch - an alternative to DX. Drop me a note on
clark@lodge.org with a good time.

| This would be a shamelss plug, but the software is open source, so....
There is software at http://dvdvault.sourceforge.net that we wrote that
uses
optical libraries to create an HSM environment. I am working on a tape
solution now, but it will be a couple of months before anything is
released.
Nearly all the work has been on ASACA Blu-Ray and DVD libraries, but
I have used a Plasmon once with UDO drives. It only runs under LINUX,
but ASACA uses it to build an appliance that they sell that looks like
a
Windows 2000 server to remote systems. Also supports FTP and NFS
access. There are currently 9 commercial sites using the software
(that
I know of). Basically the software just exports /cache, and
transparently
(somewhat) moves the files to optical media later. It retrieves the
file back
to hard disk whenever you try to read it (one the first read, so that's
where the
delay will show up).
I have used DX for many years (starting back when it was OTG, before
Legato/EMC
bought it) and the product is very good. Only works on Windows (they
have UniTree too
under *NIX, but that is an entirely different product), but it is one
of the best
archival solutions I have ever used.
Veritas has a good product (they keep changing the name over the
years), also.
All commercial products have a distinct cost issue to address. Keep in
mind that
yearly software support is probably where the real cost is, and that
can be
15-20% of the purchase price per year. You can go without support, but
you better
not upgrade to a new O/S or new hardware without support.
