Abstract
Mirrored volatile memory in a storage system is configured with a dual cast region of addresses. Buffers in the dual cast region are allocated for data associated with a received Write IO. A host IO device associates the dual cast addresses with the data. A switch or CPU complex recognizes the dual cast addresses associated with the data and, in response, creates and sends a first copy of the data to a first volatile memory mirror and creates and sends a second copy of the data to a second volatile memory mirror. The second copy may be sent via PCIe NTB between switches or CPU complexes.
