That is what my var has told me recently, but was hoping there was someone
that had found another way to make it work. We were lead to believe
originally that our three tiered solution to our storage problem would work.

If someone knows a third party software package that can handle this on an
NT platform to reduce the storage on a SAN, please let me know. It seems
that there is one package that runs on a SUN called LSC that might work, but
we would rather have this management software on a Windows platform since
our SAN is comprised of several storage nodes in Legato that run on Windows
2000 and will run on Windows 2003 in the future. Though we run some SUN
servers, our future for Unix will largely be on HP. Most support staff is
more knowledgeable of Windows than Unix.

If a vendor replies, send it privately to me, since I do not want to have
this question turn into a marketing campaign.

Ello,

Ok im shooting from the hip here (just had a chat with a colleague to
confirm):

As far as I (the proverbial we) know DiskX2000 "doesnt" (at this stage)
support the three tier approach. DXUL does.

Having spoken to our channel supplier a while ago we beleive it is on the
books for a future (i.e. not at the moment) release of DiskX2000. (this
being what quite a few people want to do).

I know you can have numerous move groups and rules within the same system -
but - as soon as you go external DiskX2000 has trouble following the action
to completion (i.e.: rename a file at the front end and it will do it - but
will then attempt to rename it on your secondary or third or fourth media
(down the chain). If any of these processes fail there is no way for the
original rename to know about it and to "fail". Hence you could potentially
get into a corrupt scenario.

What you should be reading in the above is that DXUL (Unix / Linux) does
allow you to do this (if memory servers me right - up to 15 locations). But,
this is a complete different code base from DX2000 and you need a
"certified" DXUL person to install / setup the application.

Now I might be talking complete garbage so I suggest you talk with your
local supplier or your channel support to confirm this.

Regards,

Riaan

Has anyone here used Legato's HSM product. Want to set a three tiered system
where data that os old is first moved to Blade Store disk from a SAN. If a
user accesses the file again it would be moved back to the SAN from the
Blade Storage. If the data is not accessed on the blade store for a period
of time it will be moved to tape only.

This would be a three tiered HSM solution. Would want the capapbility to
access the data from any of the three levels.
