SYSTEM OF HOST CACHES MANAGED IN A UNIFIED MANNER

摘要

A method and system for host caches managed in a unified manner are described. In an example, a server in a clustered environment designates cache ownership for a cluster application to the cache on one of the hosts. While the application is running on this host, the server monitors data writes made by the application. Upon detecting that the application is running on a different host in the clustered environment, the server can transfer cache ownership to the new host and selectively invalidate cache blocks in the cache of the new host based on the data writes that were previously monitored.

1. A system for managing a plurality of caches, the system comprising:
a plurality of hosts in a clustered environment, each host coupled to a cache of the plurality of caches; and a server to (1) designate cache ownership to a first cache of the plurality of caches on a first host of the plurality of hosts for an application running on the first host, (2) monitor data writes made by the application while the application is running on the first host, (3) detect that the application is running on a second host in the clustered environment, (4) transfer the cache ownership to a second cache on the second host, and (5) selectively invalidate cache blocks in the second cache based on the monitored data writes.
