An application may issue write operations intended for a SAN via a server cache. Monitoring of the SAN (e.g., the autonomous persistent cache of the storage arrays of the SAN), allows caching performance to be controlled by a write caching policy. The server cache memory may be increased, decreased or eliminated according to the write caching policy. In one embodiment, a storage volume manager may adjust the latency of write operations in the server cache. In some embodiments, the write caching policy may adapt and learn characteristics of the storage environment, which may include calibrated values for messaging timestamps.
