Standard deduplication is the elimination of redundant data on a single storage system. Whether that system is used for backup or primary data, the goal is to put as much data as possible on a single storage system so that…

At its core, deduplication is an enabling technology. First, it enabled disk based backup devices to become the primary backup target in the data center. Now it promises to enable the all-flash data center by driving down the cost of…
Short of buying a new storage system with storage efficiency (deduplication and compression) built in, it is difficult to add the technology to an existing storage array. Today there are two ways to accomplish this. First, you can wait for…
In recent months there has been a lot of attention given to how primary storage deduplication is being implemented; should it be implemented selectively, or always on? The problem with this discussion is that it first assumes that the existing…
Retroactive deduplication is the ability to add deduplication to an existing storage array without the vendor having to change its storage software. One vendor that seems to be out in front with retroactive deduplication is Permabit. On a recent Podcast…
Deduplication, along with compression, provides the ability to more efficiently use premium priced flash capacity. But capacity efficiency comes with at least some performance impact. This is especially true on all-flash arrays where data efficiency features can’t hide behind hard…
Tier-1 vendors are falling behind startups in offering a complete data efficiency solution. As we discussed the reasons why they are so far behind in our recent article, “The Tier-1 Storage vendor Deduplication and Compression challenge“, integrating a new technology…
Data centers are ready for increased data efficiency that they can get from primary storage deduplication and compression, especially for flash based storage systems. The cost of flash justifies these data reduction technologies and flash’s high performance actually enables their…
IT professionals expect a lot from their storage systems; they want volume management, thin provisioning, snapshot, clones, automated tiering, replication etc. Increasingly today, they want deduplication and compression as well, so they can squeeze every ounce of capacity out of…
Compression has been available in one form or another for decades, but most of the time compression is applied as data is moving off of primary storage. For example, most backup software or hardware compresses data as it moves into…
