Nimble Replication Witness Support matrix

jlangmead — Wed, 01 Jun 2022 02:32:41 GMT

I'm trying to understand if it's supported to install the Nimble replication witness for Peer Persistence on an ESXi host running VMware 7.x

Looking at the Validated Configuration Matrix it infers it's only qualified for VMware 6.5 and 6.7. please can someone confirm this?

In addition to the above - can someone please confirm if the Witness needs to be on the same subnet as the Nimble Group management IP address or not as I'm seeing conflicting information:

HPE Nimble Storage and HPE Alletra 6000 Peer Persistence - Deployment considerations for NimbleOS 5.1 and later

Page 10

"Although the Witness does not need to be on the same subnet as the array group’s management network, the Witness IP addresses must be routable from the array group’s management address, ideally through the default gateway."

In the Nimble GUI Admin guide GUI Administration Guide (hpe.com)

Page 128 it says "Note: The Witness must be on the same management subnet as the arrays."

Kind regards

Hello,
The Witness IP addresses must be routable from the array group’s management address, ideally through the default gateway." Recommended is to keep them in same subnet. But the otherway also will work.

The Validation matrix is not yet updated. Nimble replication witness for Peer Persistence on an ESXi host running VMware 7.x is supported.

Please call our support team : https://h20195.www2.hpe.com/v2/Getdocument.aspx?docname=a00050207enw
