Abstract: Systems, methods, and storage mediums storing executable instructions are disclosed for providing efficient cache mirroring, particularly in a distributed storage environment. In particular, in an aspect, a machine-implemented method, comprises: receiving an I/O request from an application; splitting the I/O request into cache LBAs and non-cache LBAs; storing the cache LBAs in a cache LUN; preparing one or more mirror write descriptors based on the cache LBAs, wherein each mirror write descriptor includes a data location and a data length; and sending the mirroring data structure and the cache LBAs to a mirroring device to store a back-up of the cache LUN. In an aspect, sending the mirroring data structure and the cache LBAs is accomplished in a single I/O request to the mirroring device.
