Abstract:
In one embodiment, a method includes replicating a production volume on a plurality of replica volume portions. Each replica volume portion is stored on a respective storage array with a respective journal. The replicating includes distributing data from a write command to a production volume across the replica volume portions using a coding scheme. A subset of replica volume portions, less than a total number of replica volume portions, includes data for a full replica volume of the production volume.
