Hi You can have few options: 1) Active/Active GPFS sites - with sync replication of the storage - take into account the latency you have. 2) Active/StandBy Gpfs sites- with a-sync replication of the storage. All info can be found at : https://www.ibm.com/support/knowledgecenter/en/STXKQY_4.2.1/com.ibm.spectrum.scale.v4r21.doc/bl1adv_continous_replication_SSdata.htm Synchronous mirroring with GPFS replication In a configuration utilizing GPFS? replication, a single GPFS cluster is defined over three geographically-separate sites consisting of two production sites and a third tiebreaker site. One or more file systems are created, mounted, and accessed concurrently from the two active production sites. Synchronous mirroring utilizing storage based replication This topic describes synchronous mirroring utilizing storage-based replication. Point In Time Copy of IBM Spectrum Scale data Most storage systems provides functionality to make a point-in-time copy of data as an online backup mechanism. This function provides an instantaneous copy of the original data on the target disk, while the actual copy of data takes place asynchronously and is fully transparent to the user.

Once it?s mirrored to a new cluster elsewhere what would be the step to get the filesystem back up and running. I know that AFM-DR is meant for this but in this case my client only has Standard edition and has mirroring software purchased with the underlying disk array. Is this even doable?
