Oracle Database's ASM Integrated into 3PAR's Thin Provisioning
[Database Journal]
3PAR, with this latest co-development with Oracle, has become the the first storage vendor to bring ASIC-accelerated space reclamation. In the environments that use ASM, Oracle's Database's integrated file system and volume manager and 3PAR Thin Provisioning deleting a tablespace or database, adding disks to an ASM disk group can result in unused disk space. The unique 3PAR technology works with Oracle's ASM Storage Reclamation utility to increase the storage utilization and operational efficiency in Oracle Database environments by capturing previously unused space. Identify unused disk space with Oracle utility and compact the ASM environment and write zeros to the free space in a single command then use 3PAR Thin Persistence to detect the zero writes and eliminate the capacity. These quick processes are performed online and non-disruptively.
