EMC Solutions Group is currently in the process of certifying the new SRA for VNXe with SRM 5.1. This SRA allows VNXe customers, running release MR4, to use VMware's Site Recovery Manager. We expect the certification process to complete soon. In the meantime, here's a preview of the SRA and associated Release Notes. The SRA is pre-release software, and until certification is complete, it is not supported by either EMC or VMware in production SRM environments. Try it out and respond to this posting with your feedback. Please read the Release Notes for pre-reqs and necessary set up information.
