HP 3PAR Thin-to-Fat and Fat-to-Thin Conversion
In previous releases of the HP 3PAR OS, customers had to perform an offline transition in order to change the provisioning attributes of a volume. This used the legacy physical copy technology where upon completion of the copy, all the VLUNs and applications had to be manually moved from the old VV to the new one. With HP 3PAR OS 3.1.2 you now have the ability with HP 3PAR Thin-to-Fat and Fat-to-Thin Conversion to convert from a thinprovisioned volume to a fully-provisioned volume (or vice versa) without requiring an offline transition.
Fat-to-thin saves space for volumes that are sparsely consumed VMware datastores while thin- to-fat saves on thin provisioning license usage for data stores that are currently thin provisioned volumes and mostly or completely allocated.
