Best Practices: Rapid NFS
This topic introduces some recommended best practices for using Rapid NFS operations with the DR Series system.
- Containers must be of type NFS/CIFS
- RDA containers cannot use Rapid NFS. If you have existing NFS/CIFS containers, you do not need to create new containers to use Rapid NFS; you can install the plug-in (driver) to existing clients.
- The Rapid NFS plug-in (driver) must be installed on client systems
- After the plug-in is installed, write operations will go through Rapid NFS while metadata operations such as file creates and permission changes will go through the standard NFS protocol. Rapid NFS can be disabled by uninstalling the plug-in.
- Markers must be set on the client, not in the DR Series GUI
- If you are using a DMA that supports a marker, should explicitly
set it. Your containers should have the marker type of
None until you set the marker using the Mount command
on the client (after installing the Rapid NFS plug-in). For existing
containers, re-set the marker using the procedure that follows.
For example, if you wanted to set the CommVault marker (cv):
mount -t rdnfs 10.222.322.190:/containers/backup /mnt/backup -o marker=cv
Mount command usage:
rdnfs [nfs mount point] [roach mount point] -o marker=[marker]
where:
nfs mount point = Already mounted nfs mountpoint
roach mount point = A new mount point
marker = appassure, arcserve, auto, cv, dump, hdm, hpdp, nw, or tsm
- Your DR Series system must meet the minimum configuration
- Rapid NFS is available on 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. Kernels must be 2.6.14 or later. For a list of supported operating systems, see the Dell DR Series System Interoperability Guide .
- Rapid NFS is stateful
- If the DR Series system goes down, the connection will terminate. DMAs will restart from the last checkpoint.
- Rapid NFS and passthrough mode
- If Rapid NFS mode fails for any reason, the DR Series system falls back to regular NFS mode automatically. For details, see Monitoring Performance.
- Rapid NFS performance considerations
- When using Rapid NFS on your client, Dell recommends that you do not run other protocols to the DR in parallel, as this will adversely affect your overall performance.
- Rapid NFS acceleration constraints
- Rapid NFS does not support:
- Direct I/O memory
-
Mapped files
- File path size greater than 4096 characters
-
File write locks across clients
