I hope they treat words as well as Mr. Dumpty, who also said: "When I make a word do a lot of work like that, I always pay it extra."
So, dearest vendors, you can't jump into a market you're already in; there's no such thing as file-level de-duplication (that's single instance storage, as even EMC calls it when talking about Centera); you can't call it revolutionary or the first when you're adding a set of features that a competitor has had for years; and finally -- and most significantly -- you're only a "leading vendor of whatever you sell" if you're No. 1 or 2 in sales.
Thats not to say Nexsan and EMC didn't announce useful additions to their product lines. Nexsan's iSeries appliances, which bear a striking resemblance to SanRad's V-Switches, do add snapshots, mirroring, and replication to the basic feature set of the SAS/SATA Boys and Beasts, which already had just about the best spin-down MAID features on the market.
EMC's Celerra single instance storage and compression will save many users a bunch of disk space while avoiding the creation of storage I/O hotspots that could be de-dupe's Achilles heel for some primary storage applications. Once an administrator turns on de-dupe for a file system, a background process identifies duplicate files using a hash function and inserts intelligent links into the file system to replace the duplicate copies.
