Synchronous mirroring of NVLog to multiple destinations (architecture level)
Abstract:
Systems and methods herein are operable to simultaneously mirror data to a plurality of mirror partner nodes. In embodiments, a mirror client may be unaware of the number of mirror partner nodes and/or the location of the plurality of mirror partner nodes, and issue a single mirror command requesting initiation of a mirror operation. An interconnect layer may receive the single mirror command and split the mirror command into a plurality of mirror instances, one for each mirror node partner, wherein the mirror instances may be simultaneously launched. After the plurality of mirror operations has begun, the interconnect layer may manage completion reports indicating the completion status of respective mirror operations, and send a single return to the mirror client indicating whether the mirror command succeeded.
