SRDF/A support for VMware vVols: Embedded VASA 3.0 Provider (EVASA) which supports SRDF/A replication for VMware vSphere Virtual Volumes (vVols) with an RPO of five minutes. EVASA is only supported on new PowerMax arrays and cannot be added to existing arrays.
SRDF/Metro Smart DR: SRDF/Metro and SRDF/A integration provides high-availability disaster recovery solution for SRDF/Metro active/active environments.
Smart DR provides SRDF/Metro with a single asynchronous target R22 volume which may be populated from either the R1 or R2 volume of an SRDF/Metro paired solution. Adding the capability for R1 and R2 to share a single asynchronous R22 volume simplifies setup, maintenance capabilities, system requirements, and reduces the amount of disk space required for a single target system.
Smart DR provides the ability to fail over or fail back to the DR site while retaining the metro environment. Smart DR can be implemented non-disruptively onto existing SRDF/Metro environments.
