Configuring CIFS optimization
This section describes how to optimize CIFS. It includes these topics:
You display and modify CIFS optimization and SMB Signing settings in the Optimization > Protocols: CIFS (SMB1) page and the Optimization > Protocols: SMB2/3 pages.
CIFS enhancements by version
This section lists and describes new CIFS and SMB features and enhancements by RiOS version.
• RiOS 9.5 added the following support:
– Ability to optimize Distributed File System (DFS) shares over SMB2/3.
– Ability to make SMB2 files, directories, and shares case insensitive by entering the protocol smb2 caseless enable command.
• RiOS 9.2 provides support for SMB 3.1.1 latency and bandwidth optimization. It also provides support for SMB file sharing as well as Windows domain integration for Windows 10 and Windows Server 2016 Technical Preview 2.
• RiOS 9.0 and later provide support for SMB 3.02 latency and bandwidth optimization.
• RiOS 8.5 and later support Active Directory integration with Windows 2012 domain function level.
• RiOS 8.5 and later provide support for SMB3 latency and bandwidth optimization.
• RiOS 8.0 and later provide support for SMB1 signing settings for macOS Lion (10.7) and Mountain Lion (10.8). RiOS 8.0 doesn’t support SMB2 signing settings for macOS Lion (10.7) and Mountain Lion (10.8).
CIFS latency optimization doesn’t require a separate license. SMB1 is enabled by default.
Typically, you disable CIFS optimizations only to troubleshoot the system.
