Determining server write activity levels to use to adjust write cache size

摘要

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.

主权项

1. A computer program product comprising a non-transitory code module implementing code for indicating a server write activity level for a server in communication with a storage server having a write cache, wherein the code executes to perform operations, the operations comprising:
gathering server write activity information at the server on a per page basis for multiple memory pages which are accessed in the server; processing the server write activity information to determine a server write activity level comprising one of multiple write activity levels indicating a level of write activity by performing:
determining a page write activity level for each of the pages being accessed in the server; andprocessing the page write activity level of each page to determine the server write activity level; and transmitting the determined server write activity level to the storage server, wherein the storage server uses the determined server write activity level to determine whether to adjust a size of the storage server write cache.
