Abstract:
A mechanism is provided in a data processing system for volume placement across remote replication relationships. Responsive to applying a volume placement optimization to a source storage pool having at least one volume with a replication target in a target storage pool, the mechanism determines whether the source storage pool and the target storage pool have identical storage volume membership. Responsive to determining the source storage pool and the target storage pool not having the same storage volume membership, the mechanism generates workload performance data for each non-shared storage volume in the target storage pool that does not have a corresponding member of the source storage pool. The mechanism generates a hardware profile for hardware of the target storage pool. The mechanism generates a volume placement optimization for the storage volumes in the target storage pool based on the workload performance data for each non-shared storage volume in the target storage pool and the hardware profile for the hardware of the target storage pool.
