SMB Direct on Windows client

Answer: Windows 10 and Windows 11 can use SMB Direct as clients when the edition/build and RDMA hardware requirements are met, but Windows client cannot act as an SMB Direct server. Windows Server remains the server-side platform for this workload.

Administrator playbook

Decide, verify, and document

Use the curated answer as a starting point, then prove the outcome against the target tenant or device.

What it means

An RDMA-capable network adapter is required
Current Windows client support includes Enterprise, Education, Pro for Workstations, and qualifying Windows Pro 22H2 clean installations or later
Windows 10 and Windows 11 are client-only for SMB Direct and cannot provide the SMB Direct server role

What to check next

Confirm both endpoints, the client edition and build, and RDMA-capable adapters
Verify SMB Multichannel and RDMA state rather than inferring SMB Direct from link speed
Use Windows Server when the Windows system must provide the server side of an SMB Direct connection

Verify success

Confirm the feature is present or enabled on the target edition and build.
Test the intended workflow with a pilot device and least-privileged user.
Confirm policy reports success from the actual management authority.

Escalate when

The documented edition and hardware requirements are met but the feature is absent.
Policy reports success while the user or device state is incorrect.
Licensing or OEM terms—not technical prerequisites—control the outcome.
