This one sort of snuck out the door: with the latest version of the DL3D code, EMC has added support for Symantec's OST initiative.
OST is a way for Symantec NetBackup to address "disk as disk" rather than as virtual tape. More important than this, in my mind, is the ability of an OST enabled device to replicate in a much more intelligent way, and in a way that tightly integrates with the backup application.
What do you need from Symantec? Well you need NetBackup v6.5. And you need the OST plug-in installed on any media server that is going to connect to the DL3D. Connection over IP (only) is supported. And in Symantec's parlance, the DL3D becomes a "storage server".
This storage server contains Logical Storage Units which are available to Media Servers. The Media Servers then access the pool of deduplicated storage on the DL3D as they would any other NFS or CIFS attached storage.
The big deal here is that the Media Servers can now instruct the DL3D to replicate to a target DL3D, and the NBU catalog will be updated to reflect the fact that the backup data now exists in two locations. Just as significantly, because it is the DL3D doing the replication (not the NBU Media Server), only deduplicated data needs to be transmitted; typical bandwidth savings can be 90% or more.
In short: it is the best of both worlds. All the goodness of deduplication, in that you get capacity savings in both storage and network for replication. And all the goodness of letting your backup application catalog where all backup data is, and what retention policy it follows.
There are a few other features that made their appearance along with OST support, and I will talk about those in upcoming posts.
