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
