NOTES:

The DR4X00 build version and screen shots used for this paper may vary slightly, depending on the

version of the DR4X00 operating system.

See NetVault DR Series Backup Appliance Application notes, DR4X00 and NetVault SmartDisk

documentation for additional information.

6 Setting up NetVault SmartDisk on the Dell™ DR4X00 Disk Backup Appliance

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.
