Abstract
Described herein is a novel technique for implementing an unordered delivery (UOD) of write logs between nodes in a cluster to optimize processing resources during log mirroring operations. A mirroring entry may be generated for each write log in a local log cache constituting the write log and an order indicator for the write log. The order indicator may be, for instance, a storage location of the write log in the local log cache. The mirroring entry may then be forwarded across a network from the local node to the remote node, where the mirroring entry may be stored at a next available location of an interim cache at the remote node independent of the write log storage location in the local log cache.
