Best Practices: Rapid CIFS
This topic introduces some recommended best practices for using Rapid CIFS operations with the DR Series system.
- Containers must be of type NFS/CIFS
- RDA containers cannot use Rapid CIFS. If you have existing NFS/CIFS containers, you do not need to create new containers to use Rapid CIFS; you can install the plug-in (driver) to existing clients.
- The Rapid CIFS plug-in (driver) must be installed on client systems
- After the plug-in is installed, write operations will go through Rapid CIFS while metadata operations such as file creates and permission changes will go through the standard CIFS protocol. Rapid CIFS can be disabled by uninstalling the plug-in.
- Your DR Series system must meet the minimum configuration
- Rapid CIFS is available with a DR Series system and a client with a minimum of 4 CPU cores running at a minimum of 4 GHz cumulative processing power and 2 GB memory. For a list of supported operating systems, see the Dell DR Series System Interoperability Guide.
- Rapid CIFS is stateful
- If the DR Series system goes down, the connection will terminate. DMAs will restart from the last checkpoint.
- Rapid CIFS and passthrough mode
- If Rapid CIFS mode fails for any reason, the DR Series system falls back to regular CIFS mode automatically. For details, see Monitoring Performance.
- Rapid CIFS acceleration constraints
- Rapid CIFS does not support:
- NAS functionality
-
Optlocks (but supported if a single client is writing)
-
Byte-range locks
-
- Optimization of very small files (less than 10 MB). File size can be adjusted using configuration settings.
-
FILE_NO_IMMEDIATE_BUFFERING and FILEWRITE_THROUGH operations (sent via CIFS only).
- File path size greater than 4096 characters
- NAS functionality
