Thin Provisioning

The thin provisioning function permits the capacity of storage systems to be used efficiently. Devices (LUNs) with preconfigured virtual capacity are offered to the application, while internally the storage system provides the necessary physical capacity. Thin provisioning requires a corresponding configuration in the storage system.

SHC-OSD supports thin provisioning for the storage systems ETERNUS DX S2 and higher and for Symmetrix (where it is called "virtual provisioning"). SHC-OSD has monitoring and information functions for thin provisioning. A detailed description of the thin provisioning function is contained in the “SHC-OSD” manual [29 (Related publications)].
