Everybody knows that the hottest thing in storage in 2008 was data deduplication. Don't expect it to cool off in 2009.

By Dave Raffo

Even with all of the data deduplication product rollouts in 2008, we can expect plenty more throughout this year. CommVault got the ball rolling when it launched Simpana 8 with block-level deduplication and dedupe for data on tape and disk in January. Quantum Corp. brushed up the integration and replication capabilities of its DXi7500 dedupe backup box around the same time. While there was plenty of news and new products in 2008, we don't expect the onslaught to let up -- even more data deduplication products, including some for primary storage, are slated to roll out soon. The following is a roundup of dedupe products currently in the pipeline:

Dell Inc. In November, Dell said it would bring out dedupe products in 2009 that will integrate with Quantum's dedupe products. Quantum also licenses its target deduplication software to Dell's storage partner EMC Corp., so it's expected that Dell's products will be compatible with EMC's Disk Library, if not an outright OEM deal. Dell said it would also sell Quantum's replication software to copy deduped data for disaster recovery.

EMC's Celerra. EMC will offer primary storage dedupe for file systems with the next upgrade of its Celerra NAS platform, due early this year. EMC will use single instancing from its Avamar dedupe product

and compression from its RecoverPoint appliance. The Celerra dedupe will compress files with low usage activity, and single-instance files to remove duplicates. EMC's NAS rival NetApp began offering dedupe for primary storage a few years back, but no other major storage vendors have followed suit until now.

Hewlett-Packard (HP) Co. There have been no public announcements, but David Rogers, manager of product marketing for HP StorageWorks data protection, tells SearchStorage.com that the company will add replication on the firmware of its dedupe products, the StorageWorks D2D Backup System and StorageWorks Virtual Library System (VLS). Rogers says the replication was developed specifically for the dedupe products and will be a licensed feature.

In addition to these new products, expect enhancements to the dedupe products already out. For instance, FalconStor Software Inc. added a NAS interface to its virtual tape library (VTL) dedupe product in early December.
