IBM has revealed a new TS7530 virtual tape system with no deduplication capabilities at all, just hardware compression. The Virtualization Engine TS7530 is presented by IBM as an intervening system between open systems servers and tape with tape being the final resting place for data. It is designed to augment the tape backup …
VTLs of that size usually really seem constant input at far above of what a few thumpers can handle - maybe this is just too much for current deduplication implementations - otherwise it shouldn't be hard to add a "few" nodes into the VTL that are dedicated for deduplication. I dont know if FalconStor also uses dedicated nodes for compression like the "competitior" system we got at our site.
(of course they didnt use a hw gzip engine... nono... never use anything fancy if you can bill much anyway)
also, I could well imagine that the customers in question dont want to rely on some magic black box but rather have a more easily recoverable state on the tapes, in case the datacenter and VTL blow up.
