Abstract
A method of writing to cache in a clustered environment. A first node in a storage cluster receives a request to write data from a user application. The first node determines if the data is owned by a remote node. If the data is owned by a remote node, the data in the remote node may be invalidated, if necessary. Such invalidation may not be necessary if a global cache directory is utilized. Thereafter, the data is written in a cache of the first node. Additionally, the data is written in a cache of a partner node of the first node. Confirmation of the cache write in the partner node is then received in the first node.
