Abstract
A technique for allocating a write cache allowed data size of a write cache from a plurality of write caches to each of a plurality of storage volumes, calculating a write cache utilization of the write cache for each of the respective storage volumes, wherein the write cache utilization is based on a write cache dirty data size of the write cache allocated to the respective storage volume divided by the write cache allowed data size of the write cache allocated to the respective storage volume, and adjusting the write cache allowed data size of the write cache allocated to storage volumes based on the write cache utilization of the write cache of the storage volumes.
