Performance improvements for a thin provisioning device |
| 摘要 |
A computer reduces data fragmentation on a thin provisioned storage system. The computer receives a storage request. The computer determines a virtual storage size based at least in part on the received storage request. The computer creates an assigned virtual list that includes a list of reserved physical storage locations associated with the storage request. The computer further receives a WRITE command, and responsive to the WRITE command, allocates storage based at least in part on the created assigned virtual list. |

1. A method for reduced data fragmentation on a thin provisioned storage system, the method comprising:
receiving, by one or more processors, a storage request; determining, by one or more processors, a virtual storage size based, at least in part, on the received storage request and an over-provisioning ratio, wherein the over-provisioning ratio is determined based, at least in part, on previous storage usage; and creating, by one or more processors, an assigned virtual list that includes a list of reserved physical storage locations associated with the storage request. |
