## What you need to know

Which infrastructure assumptions need verification before deploying a two-node file-server cluster?

## Potentially affected

Use this review when preparing a two-node clustered file service.

## DSE recommendation

Draw the actual node-to-storage and node-to-client paths and have the infrastructure owners identify shared dependencies.

## Article

## Source facts

Microsoft describes failover as another cluster node taking over service after a node fails. File serving is one of several roles a failover cluster can host. The two-node deployment guidance requires appropriately certified hardware and software. It also instructs administrators to avoid single points of failure in the network connecting the nodes. [Microsoft documentation](https://learn.microsoft.com/en-us/windows-server/failover-clustering/deploy-two-node-clustered-file-server).

## Applicability

Use this review when preparing a two-node clustered file service. Identify the proposed nodes, storage, network paths, client population, and certification evidence. Review the complete deployment requirements before ordering or configuring the components.

## DSE recommendation

Draw the actual node-to-storage and node-to-client paths and have the infrastructure owners identify shared dependencies. Record which component failures the design is intended to withstand. Keep a separate list of dependencies that remain common to both nodes. Agree on file-access acceptance criteria and a controlled failover exercise before deploying the production role.

## Verification

Retain the required validation results and compare the implemented paths with the approved diagram. Test representative client file operations during the agreed node-transition exercise. Record observed interruptions and recovery time rather than assuming seamless access. Reconcile missing certification evidence, common-path risks, or failed client operations before declaring the file service ready.
