Abstract
Provided are a computer program product, system, and method for determining server write activity levels to use to adjust write cache size. Information on server write activity to the cache is gathered. The gathered information on write activity is processed to determine a server write activity level comprising one of multiple write activity levels indicating a level of write activity. The determined server write activity level is transmitted to a storage server having a write cache, wherein the storage server uses the determined server write activity level to determine whether to adjust a size of the storage server write cache.

A method, comprising:
- gathering information on server write activity at a server;
- processing the gathered information on write activity to determine a server write activity level comprising one of multiple write activity levels indicating a level of write activity;
- and
- transmitting the determined server write activity level to a storage server having a write cache, wherein the storage server uses the determined server write activity level to determine whether to adjust a size of the storage server write cache.
A method, comprising:
- receiving, from servers, server write activity levels comprising one of multiple write activity levels indicating levels of write activity at the servers;
- processing the server write activity levels of the servers to determine whether to adjust a size of a write cache for receiving writes from the servers;
- and
- adjusting the size of the write cache in response to determining to adjust the size of the write cache.
