-- A new wave of storage array vendors has joined in support of Symantec's Veritas Thin Reclamation API. Compellent, EMC, Fujitsu, HP and NetApp have announced support for the API, which allows Veritas Storage Foundation to automatically reclaim storage capacity on disk arrays with thin provisioning.
The aim of the Thin Reclamation API is to give Veritas Storage Foundation the tools to keep thin-provisioned LUNs thin over time by allowing servers and storage arrays to continually and automatically return unused capacity to the storage pool in the array.
Dan Lamorena, senior manager in Symantec's Storage and High Availability Group, says migrating volumes from "thick to thin" is easy, but that reclaiming unused capacity while keeping applications online is the key to keeping thin volumes from getting "chubby" again.
Compellent, EMC, Fujitsu, HP and NetApp join 3PAR, Hitachi Data Systems and IBM, all of which announced support for the Thin Reclamation API last year.
The aforementioned array vendors are supporting – or plan to support – Storage Foundation Thin Reclamation in the coming months.
Symantec's list of supporting platforms includes 3PAR's InServ, Compellent's SAN, EMC's Clariion CX and Symmetrix DMX lines, the Fujitsu Eternus family, HP's EVA and XP24000 systems, Hitachi Data Systems' USP-V and AMS arrays, IBM's DS8000 and XIV systems, and as yet unnamed arrays from NetApp.
Thin Reclamation is supported on Windows, Unix and Linux, and requires Storage Foundation for Windows 5.1 SP1 or Storage Foundation for Unix & Linux 5.0 MP3 and above.
