Setting client-side optimization

Setting client-side optimization

Client-side optimization (also known as client-side deduplication) is a process that can contribute to saving time performing backup operations and reducing the data transfer overhead on the network.

To configure dedupe/passthrough before the client makes a connection, you need to use the DR Series system command line interface (CLI).

 
NOTE: To update a client in the DR Series system GUI, the client must already be attached (and therefore enabled to appear in the GUI). If a client connection exists, you can select the radio button in the GUI to modify it.

You can turn client-side optimization On or Off by using the CLI commands, rda --update_client --name --mode. For more information about DR Series system CLI commands, see the DR Series System Command Line Reference Guide.

Installing the Rapid NFS plug-in

Installing the Rapid NFS plug-in

The DR Rapid NFS plug-in must be installed on to the media server type you choose (for supported operating systems and DMAs, see the DR Series System Interoperability Guide). The plug-in software enables integration between DR Series system data storage operations and the supported data management applications (DMAs). Before you install, make sure you adhere to the Best Practices covered in another topic in this chapter.

The plug-in must be installed on the designated Linux-based media server in the following directory, /usr/openv/lib/. The plug-in is installed using a self-extracting installer that installs the Rapid NFS plug-in and all of its related components. The installer supports the following modes, with the default being Help (-h):

•
Help (-h)
•
Install (-install)
•
Upgrade (-upgrade)
•
Uninstall (-uninstall)
•
Force (-force)
$> ./DellRapidNFS-xxxxx-xxxxx-x86_64.bin -help
Dell plug-in installer/uninstaller
usage: DellRapidNFS-xxxxx-xxxxx-x86_64.bin [ -h ] [ -install ] [ -uninstall ]
-h : Displays help
-install : Installs the plug-in
-upgrade : Upgrades the plug-in
-uninstall : Uninstalls the plug-in
-force : Forces the installation of the plug-in

You can download the plug-in installer from the Quest website:

•
Go to support.quest.com/dr-series, select your specific DR Series model, and then navigate to Software Downloads.
•
Locate the DR Rapid NFS plug-in and download it to your system.

After it is downloaded, follow the steps that follow to run the Plug-In Installer to install the plug-in on your designated Linux-based media server.

 
NOTE: The plug-in needs to be installed on client systems to support client-side deduplication.
1.
Download DellRapidNFS-xxxxx-xxxxx-x86_64.bin.gz from the website, as detailed previously.
2.
Unzip the package.
unzip DellRapidNFS-xxxxx-xxxxx-x86_64.bin.gz
3.
Assign execute bit to change the permission of the binary package:
chmod +x DellRapidNFS-xxxxx-xxxxx-x86_64.bin
4.
Install the Rapid NFS package. Before installing, remove the stale NFS entry.
DellRapidNFS-xxxxx-xxxxx-x86_64.bin -install
5.
Load the file system in user space (FUSE) module, if not already loaded:
modprobe fuse
6.
Create a directory on the client. For example:
mkdir /mnt/backup
7.
Mount Rapid NFS as a file system type using the mount command. For example:
mount -t rdnfs 10.222.322.190:/containers/backup /mnt/backup

If you are using a DMA that supports a marker, set the marker by using -o in the mount command. 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
 
NOTE: If you want to do a mount on AIX, you must set the nfs_use_reserved_ports and portcheck parameters first. The parameters cannot be set to 0. For example: root@aixhost1 / # nfso -po portcheck=1 root@aixhost1 / # nfso -po nfs_use_reserved_ports=1

To ensure that the plug-in is running successfully, check the log file at: tail -f /var/log/oca/rdnfs.log.

Installing the Rapid CIFS plug-in

Installing the Rapid CIFS plug-in

The DR Rapid CIFS plug-in must be installed on to the media server type you choose (for supported operating systems and DMAs, see the DR Series System Interoperability Guide). The plug-in software enables integration between DR Series system data storage operations and the supported data management applications (DMAs). Before you install, make sure you adhere to the Best Practices covered in another topic in this chapter.

You can download the plug-in installer from the Quest website as follows

•
Go to support.quest.com/dr-series, select your specific DR Series model, and then navigate to Software Downloads.
•
Locate the DR Rapid CIFS plug-in and download it to your system.

After it is downloaded, follow the steps below to run the plug-in installer to install the plug-in on your designated media server.

 
NOTE: The plug-in needs to be installed on client systems to support client-side deduplication.
1.
On the media server, map a network share to your CIFS-enabled container.
2.
Download the plug-in installer from the website, as detailed previously.
3.
Open a command prompt with the “Run as Administrator” option selected. To do this using the Windows Start menu, click Start → All Programs → Accessories. Right-click Command Prompt and select Run as Administrator.
This gives all the required privileges to install/copy the driver files to the Windows drivers folder.
4.
Run DellRapidCIFS-xxxxx.msi.
5.
Follow the installation prompts.

To ensure that the plug-in is running successfully, check the Windows Event log file.

Determining if your system is using Rapid NFS or Rapid CIFS

Determining if your system is using Rapid NFS or Rapid CIFS

Use this procedure to identify whether Rapid NFS or Rapid CIFS is installed and enabled on your DR Series system.

To determine if your system is using the Rapid NFS or Rapid CIFS accelerator:

1.
In the GUI, go to the Dashboard, and then click Container Statistics.
2.
In the Container Name drop-down list, select a NFS or CIFS container that is associated with your client.
3.
In the Connection Configuration pane of the statistics page, locate the NFS Write Accelerator or CIFS Write Accelerator field, depending on the protocol selected.
4.
Next to the Write Accelerator field is a value. Active indicates that the accelerator plug-in is installed and enabled. Inactive indicates that the plug-in is not installed or not working correctly.
