This Microsoft HCI Solutions from Dell Technologies infrastructure type offers two to four nodes in a switchless configuration for storage traffic. This infrastructure can be implemented using any of the validated and supported AX nodes. However, the number of nodes in a cluster varies between the AX node models and the number of network adapters that each model supports.
- Single-link
- Dual-link
For the two-node cluster deployment, configure a cluster witness. For details, see Configuring a cluster witness.
The switchless storage configuration has been validated with back-to-back connections for storage connectivity.
The following figure shows the switchless storage networking infrastructure:
