Overview of SMB Signing:
- SMB (Server Message Block) protocol is crucial for file sharing, print sharing, and remote administration over networks.
- SMB Signing provides digital signing for each packet, enhancing security by preventing tampering during transmission by unauthorized parties.
- Compatibility: SMB Signing is supported across all SMB protocol versions.
Performance Impact:
- Activating SMB Signing introduces a significant CPU workload for packet signing on the client side, impacting performance.
- Example: Throughput may decrease from 875 MiB/s to approximately 250 MiB/s for non-multichannel sequential read operations.
Mitigation:
- To address the performance impact:
- Deactivate Server Signing in the SMB settings within the D5000 series GUI.
- Client Deactivation: Instructions to disable SMB signing on Windows, Linux, and macOS can be found via a quick online search.
By disabling SMB Signing on both server and client sides, users can achieve optimized performance for SMB shares on the VTrak D5000 series.
