Abstract
Improved techniques for maintaining cache coherence in a consistent state are provided. These techniques implement a data storage system using a journaled mirrored cache that ensures that storage operations making up certain transactions be performed atomically, so that a system failure does not result in data loss. The improved techniques also allow for efficient communication of mirroring information.
