Alternate plan for HA config for Unity

Hi RPe

thanks for the reply...

what you saying is have 2 hosts AS  ESRS GW sever for One Unity in the first place ?  (Those 2 ESRS GW servers are independent )

Am I getting you ?

thanks !

If you want to take advantage of High availability feature of ESRS, I recommend you implement 2 ESRS-VE servers and deploy the Unity in that environment rather than enabling integrated esrs on your unity.

More information on this can be found in

Correct : Deploy 2 separate ESRS-VE virtual machines in separate environments to leverage HA requirements.

In this way you create an HA environment that is capable to support almost any device from Dell EMC for remote support.

I am on the ESRS Connectivity Support team.
We have been told by Unity Engineering that Unity does not support Centralized ESRS in an HA configuration.
I still cannot find any documentation on the Unity site to support this.

I have dealt with many customers that have run into this problem and there are only two options, of which I believe only the latter as a viable option.

1. Use the integrated ESRS in your Unity.

Drawbacks:

• If you have lots of Unity boxes, each one uses its own embedded ESRS.
• The latest Unity release has a very old version of ESRS built in. This version has multiple known bugs and security vulnerabilities outlined in ESA 2017-136, KB # 509178 (EMC ESRS Virtual Edition Security Update for Multiple Embedded Component Vulnerabilities
• There is no WebUI to the integrated ESRS, so even ESRS Support cannot diagnose ESRS issues.

    2. Deploy and provision a separate and single, non-HA Centralized ESRS VE Gateway, and have all of your Unity Boxes use this gateway.

Drawbacks:

• A waste of additional VM resources.
• No centralized solution to manage all EMC devices.

If anyone runs across any hard documentation that Unity does not Support ESRS VE, please provide a link.

Thank you!

UPdated info ....

Unity now does supports HA config but cannot HA for Call Home functionality ...
