Symantec announced that their widely-used Veritas Storage Foundation software (more commonly known as Veritas Volume Manager and filesystem) will now include thin provisioning, migration, and a new API which allows it to directly communicate with thin-capable storage arrays. This is a smart step, certainly, and ought to be useful, but storage managers should still try to manage storage use aggressively.
Update: More details have come out about Symantec’s new capability. Read my follow-up post on Symantec’s Thin API for clarification!
Here’s the gist (as near as I can tell). Veritas Storage Foundation will include the following capabilities:
- Native thin provisioning which will cause Veritas volume manager to allocate space in the Veritas filesystem only when data is written
- A thin provisioning API which allows the volume manager to communicate with certain storage arrays (3PAR is highlighted, along with HDS and HP) to allocate and reclaim space as it is used in the filesystem
- A thin migration API which allows the volume manager to tell these storage arrays to migrate existing volumes to thin-provisioned space
This is great stuff, and ought to allow folks to make better use of thin provisioning. In fact, it nicely addresses many of my concerns about thin provisioning, including un-provisioning. It’s especially nice to see that Symantec already has interested partners, and that one system (3PAR) is up and running already. Way to go!
