1Technical Setup/configuration Best Practices
This section highlights key configuration and setup best practices to successfully add the DR backup Disk
appliance for the use with NetVault Backup and NetVault SmartDisk. Please review this section carefully
before embarking on the DR4X00 and NetVault install/configuration sequences outlined in chapters 2
through 4 of this guide
NOTE: For NetVault SmartDisk, native DR4X00 replication support is not available at this time.
1.1 General Setup /configuration Best Practices
Refer to the manufacture’s documentation for additional details on the following prerequisites.
Ensure cabling configured correctly.
Configure interfaces, protocol and addressing.
oConfigure Networking infrastructure to support Jumbo Frames (MTU=9000).
Preconfigured system to run as the NetVault Backup Server and NetVault SmartDisk Server.
Alternatively a separate server can be provisioned and configured to host the NetVault SmartDisk
software.
DR4X00 preconfigured for use with the following attributes established:
oProper network connectivity with IP address or DNS name of DR4X00 Backup Appliance.
oDR4X00 Backup Appliance(s) configured with the appropriate containers needed to host
the NetVault SmartDisk instance.
oFor each container defined a network share exported via CIFS or NFS of appropriate
permission and size.
oAll authentication requirements fulfilled such as Domain name, username and password
for users setup on DR4X00 unit to provide full access to the predefined containers and
network share(s) for use as backup repositories.
1.2 DR4X00 Setup/configuration Best Practices
Each NetVault SmartDisk instance should be created and configured to run within the domain of a
single DR4X00 Storage Container. This will allow for easy management of storage consumption
therefore each SmartDisk instance should run within its own container.
Users should be created so that the NetVault Backup server user has full Read/Write access to the
container. This is a requirement for NetVault to be able to manage the configuration items and
respective objects created within said container during backup, access during recovery, and deletion
upon retirement.
1.3 NetVault SmartDisk Setup /configuration Best Practices
During installation the stage and store spaces should be defined to run from a remote location. This will be
configured during installation as the UNC network path of the CIFS share or locally defined mount points
for NFS level use over the network.

After the basic installation of NetVault SmartDisk there are various attributes and settings that need to be
made in order to tune the software for use within the DR4X00 Backup Appliance domain. These will
include the following attributes post installation and prior to adding the instance to a NetVault Backup
domain:
oCreate and configure a Chunk Index and Disk Index directory within the DR4X00 container defined
for use. This will be in the same directory structure as the stage and store spaces defined during
basic installation.
oDisable Software DeDuplication. So as to not conflict with the inline deduplication of the DR4X00
this feature must be disabled before the environment is used.
oConfigure Garbage Collection (GC) utility to run anytime. This will enable the reclamation of
retired backup segments to occur without the need to predefine windows for this activity.
oWhen using CIFS / UNC Paths: Configure the block size to be 512KB.
During installation a stage and store path are defined. These paths will host directory structures needed to operate the
SmartDisk software solution.
When prompted for the stage and store paths input the UNC path of the storage container for Windows systems or
the predefined NFS mount for Linux and Unix based systems.
After the initial installation the SmartDisk instance must be configured to run exclusively from the DR4X00 space. By
default both the SmartDisk Chunk Index and Disk Index run within predefined directory structures. The goal is to
consolidate these two object stores and define them to be hosted within a known space running on the DR4X00 in
case a migration or disaster remediation situation occurs. In order to accomplish this, this directory must be manually
created and configured for use. It is recommended that an index directory be created within the same directory level
as the store and stage directories.
Once this directory is create, following the same guidelines as those outlined for the stage and store spaces, a set of
commands can be issued to configure the SmartDisk instance as follows:
Smartdisk Home >> foundation >> bin >> smartdisk(.sh/.bat) config --add --volume <Index directory path hosted
on the DR4X00 Container> --favour “Chunk Index” --favour “Disk Index” --deny “Staging” --deny “Storage”
Smartdisk Home >> foundation >> bin >> smartdisk(.sh/.bat) config --update --volume <Store directory path hosted
on the DR4X00 Container > --deny “Chunk Index” --deny “Disk Index” --deny “Staging” --favour “Storage”
Smartdisk Home >> foundation >> bin >> smartdisk(.sh/.bat) config --update --volume <Stage directory path
hosted on the DR4X00 Container > --deny “Chunk Index” --deny “Disk Index” --favour “Staging” --deny “Storage”
This will configure the SmartDisk instance to host all the appropriate data segments and indexing information from
backup operations in separate and distinct volume locations hosted on the DR4X00 backup appliance.
Once all the appropriate volumes have been defined and attributes configured the rest of the recommended settings
should be applied to the SmartDisk instance which will include disabling software deduplication, setting Garbage
Collection to run anytime, and configuring block size settings depending on whether the DR4X00 is hosting the
SmartDisk instance via CIFS or NFS protocols.
To disable software deduplication, run the following command:
Smartdisk Home >> foundation >> bin >> smartdisk(.sh/.bat) config --dedupe-enable FALSE
To configure the proper space reclamation cycles run the following commands:

8 Setting up NetVault SmartDisk on the Dell™ DR4X00 Disk Backup Appliance
Smartdisk Home >> foundation >> bin >> smartdisk(.sh/.bat) config --add --gc-window Anytime
Smartdisk Home >> foundation >> bin >> smartdisk(.sh/.bat) config --add --dedupe-window Never
Finally if you are configuring SmartDisk on a CIFS / UNC path hosted on the DR4X00 it is recommended that a block
size of 512000 be set before data protection operations are conducted from the target configuration. In order to set
the block size of the SmartDisk instance run the following command:
Smartdisk Home >> foundation >> bin >> smartdisk(.sh/.bat) config --update –webdav 37453 --block-size 512000
Note: By default the block size is set to 32 and the webdav port to 37543. These settings should be considered when
using the above for reference.
Once the configuration settings have been applied the SmartDisk services should be restarted. Execute the following
command as needed:
Smartdisk Home >> foundation >> bin >> smartdisk(.sh/.bat) restart
The newly configured SmartDisk instance should be ready for use within a given NetVault Backup domain. Verification
of the newly configurated volumes and attributes should be conducted by running the following command:
Smartdisk Home >> foundation >> bin >> smartdisk(.sh/.bat) config --show
Once all settings have been verified and the configuration has been deemed fit for use the SmartDisk instance can
now be added to the NetVault Backup server.
