To make VNXe products even easier to maintain, EMC has incorporated EMC Secure Remote Support (ESRS) into the VNXe Operating Environment (v2.2.x or greater), and it is also 100% customer installable. To see a brief overview of the steps for enabling ESRS on your VNXe to receive the benefits of connectivity, take a look here: https://community.emc.com/docs/DOC-18499

Note that VNXe products can also support ESRS using a Gateway server, which would be appropriate in a heterogeneous environment including multiple EMC products. However, if your environment includes only one (or more) VNXe systems, no Gateway server is needed.
