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
