RSSMany technologies promise to help us get a handle on storage, but data deduplication delivers-if it's done right. Network Computing's latest Tech Center delivers news, opinion and exclusive research reports on all aspects of data dedupe and WAN replication technology: Best practices, emerging trends, and new products and strategies.

Sepaton Goes DeDupe
Sepaton adds deduplication along with capacity and bandwidth optimization to its enterprise storage platform with today's introduction of the S2100-MS2. The S2100-MS2 sits in the midrange of the Sepaton products. A rack-ready device with capacity to back-up and restore of up to 40TB is aimed at small enterprises, the MS2 can be equipped for up to 160TB of useable data, while the existing ES3 can be configured for up to 1.6 Petabytes of data. The 2100-MS is currently available, listing for a two-node 30 Terabyte system starts at $321,000.
Nexenta Deduplicates ZFS
Nexenta Systems Inc. has enhanced its NexentaStor 3.0 product to include in-line deduplication for Zettabyte File System (ZFS). The company also used NexentaStor 3.0 as the basis for its Nexenta Virtual Machine Datacenter (VMDC) 3.0 product, which adds support for Microsoft's Hyper-V virtualization environment.

Is All Storage Hype Bad?

Posted by George Crump
Cloud Storage, Automated Tiering, FCoE and deduplication are the current over-discussed technologies in storage. At some point, a technology gets discussed so much that it becomes over-hyped. The reality is that most of the potential users of any of these technologies are not even close to adopting them. Especially right now, most IT professionals are just trying to keep their heads above water. Is all storage hype bad, though?

Deduplication Replication - CommVault
February 19, 2010 10:00 AM
Posted by George Crump
CommVault was one of the first enterprise back-up software vendors to integrate deduplication into their product offering. While it wasn't a surprise that they did this, it was a surprise that they were able to add the ability to deduplicate to tape. In my most recent regular blog post on Network Computing, I covered the trend to deduplicate on media other than traditional disk-based systems. CommVault's hybrid approach is a unique compared to how others perform deduplication, and worth examining.

Deduplicating Elsewhere

Deduplication technology discussions usually center on deduplicating the backup target. That makes sense, as this is where the biggest payoff is for the technology. Increasingly, the discussion is moving more to using deduplication as a part of archive disk or primary storage. Deduplication, however, is also branching out beyond standard disk, and there are areas to consider whether applying the technology is worth the investment.

Deduplicating Replication - Atempo

Posted by George Crump
Enterprise Backup Software manufacturer Atempo has entered the deduplication marketplace, as have a growing list of other software manufacturers. Hopefully, we can cover all or most of them in future entries. Atempo has integrated deduplication as part of its Time Navigator agent software that is installed on a server to be backed-up. Atempo deduplication is source-side, meaning not only does it reduce the amount of data stored on disk, it also reduces the amount of data transferred across the network. The agent that includes deduplication has been available for Linux, Macintosh, Windows, AIX and HP-UX operating systems. They recently added support for Solaris, Windows 2008 and Windows 7.

Is D2D2C The Next Big Thing In Backup?
February 2, 2010 9:30 AM
Posted by Howard Marks
Today CommVault announced that their Simpana integrated backup and archiving software can now use public cloud providers in addition to local disk and tape as a data store. I hope that CommVault is, as they were with deduplication, leading a new wave of disk-to-disk-to-cloud (D2D2C)backup and archive solutions. While I firmly believe that there's a lot of life left in tape, especially for long retention archives with relatively low access rates, 25 years of consulting to organizations has taught me that tape drives, like backhoes and other heavy equipment, should be left to trained professionals. Small and even mid-size organizations rarely handle tape properly, leaving them exposed to data loss.

Deduplicating Replication - NetApp
February 1, 2010 10:00 AM
Posted by George Crump
NetApp made headlines last year in its attempt to purchase Data Domain. While the story of that not working out has been very well documented, NetApp also had two other deduplication technologies. One leverages the ability of OnTap (the NetApp OS) to do deduplication and the other is available with their VTL solution. This entry will focus on the former.

One of the great ironies of storage technology is the inverse relationship between efficiency and security: Adding performance or reducing storage requirements almost always results in reducing the confidentiality, integrity, or availability of a system.
