TECHNIQUES FOR MANAGING DATA IN A STORAGE CONTROLLER |
摘要 |
A technique for limiting an amount of write data stored in a cache memory includes determining a usable region of a non-volatile storage (NVS), determining an amount of write data in a current write request for the cache memory, and determining a failure boundary associated with the current write request. A count of the write data associated with the failure boundary is maintained. The current write request for the cache memory is rejected when a sum of the count of the write data associated with the failure boundary and the write data in the current write request exceeds a determined percentage of the usable region of the NVS.
