Hi Steve, The reason that neither Veritas Storage Replicator or other HSM packages currently support HSM migration of data to and from NetApp filers is because DataONTAP does NOT support DMAPI protocol. DMAPI means Data Management Application Programming Interface and this along with the X/Open Data Storage Management (XDSM) standard allow HSM functionality across a wide range of operating environments without sacrificing system reliability. Without this, the HSM software has no idea of file attributes or location. This reason I'm giving you all this exciting info (YAWN) is that most, if not all, HSM packages use these protocols. Until NetApp is able to support these protocols, or the 3rd party companies are able to come up with some other way of doing HSM, we will not be able to offer an HSM solution to our customers. Now, Good news/ Bad News. The good news is we are receiving more and more requests for this functionality, and I do know that engineering is looking at possibly adding support for the DMAPI protocol. The bad news is that no date has been set for beginning to implement this. Sorry we can't tell you anything better.

Hello everyone!
We are considering implementing an F840 with around 4TB into a mixed UNIX and Win2K environment. My question to this much respected community is can we implement an HSM solution like say Veritas Storage Replicator to extract stale files and put them out to tape with a Netapp? I have been told know but am hoping yes.
Thanks in advance

I had a customer who had excellent luck doing this operation from a Windows 2000 PC. What they did was have one of their software engineers create a simple Visual Basic application that used the Windows 2000 search facility to scan for files older than some date, and then mark them for archive. The next time they backed up, they moved the files off the filer with this utility and onto tape. They even made it so that they could restore in the same way. It was simple, but worked perfectly with very little overhead. Kind of like a filer!
:)
My only problem was that this customer went out of business before I got a chance to get a copy of this utility. Perhaps something work considering. It shouldn't be a big deal to do in VB. You could of course do it in Unix as well. While not HSM, execution of the concept does deliver the functionality most people are after.
