Intersight Standalone Mode (ISM)
In an ISM deployment, nodes are connected to two Top-of-Rack (ToR) switches and do not require Fabric Interconnects (FIs). Only rack-mount servers are supported. Servers are centrally managed using Cisco Intersight.
-
We recommend deploying three nodes for a standard Nutanix production cluster.
-
Single node and two-node clusters can be deployed in Edge and branch locations with an existing high-performance network fabric.
For detailed cluster deployment instructions using ISM, see the Cisco Compute Hyperconverged with Nutanix ISM Field Guide.
