I've also heard good things about Data Domain.
On the other hand, does anyone have any experience with the A-SIS deDupe technology from NetApp? Sounds great, except for the 'out of band' nature of it.

Wilbur:
What are your performance requirements? Adding compression/deDup into this has a serious impact on I/O performance, it will pretty much totally screw any read-ahead optimization.
If you still want to go ahead, look at Data domain's Gateway series. It doesn't formally support Netapp, but i'm sure you could use it. This will do exactly what you want, as long as you want NFS!

Hi toasters,
We have a couple of 100 TBs of heterogenous storage (some from netapp), and see that our storage grows close to 60% over year. We were looking at alternatives for managing this data growth. Compression was one of the techniques we were considering for our nearline and (possibly) primary storage. Our applications cannot change to do their own compression, so it boils down to doing this in the storage layer or through an external device. Also, we'd like to not have any performance impact and compression to happen transparently. Deduplication technology from storage vendors would help, but it is not a hetrogenous solution.
I am not aware of any compression technology from netapp. Are you folks aware of any solutions? Would love to hear your experience with those or other alternative ways you deal with the storage growth problem while managing costs.
Thx, Wilbur
The issue with any compression technology is the latency it adds to any workload and what happens with a large number of people doing the same thing.
Would you not be better at looking at an archiving product that can archive off the older files leaving stub files behind so any application can carry on working with no interruption. Assuming that the data is stored as lots of files.
Perhaps you need to look at some traditional HSM type product that integrates with a tape library except instead of using a physical tape library you use a VTL which will do the deduplication and compression for you. You then have the added advantage that the VTL can spit out copies of the virtual tapes to be taken off site for DR. This type of solution should then be platform independent.
