vRanger 7.8.1 - Integration Guide for NetVault SmartDisk

System requirements

System requirements

Before installing vRanger and NetVault SmartDisk, ensure that you read and understand the requirements and limitations of both products.

For vRanger and NetVault SmartDisk to integrate, you must use the following versions:

•	vRanger Backup & Replication 7.6.5 or later

•	NetVault SmartDisk 11.4.5 or later.

Software requirements

Software requirements

NetVault SmartDisk has the following software requirements for Windows®:

•	Microsoft Visual C++: If it is not already installed, NetVault SmartDisk automatically installs the applicable portions of the Microsoft Visual C++ 2005 SP1 Redistributable Package. No additional steps are required by you.

•	System-memory requirements: Verify that your Windows system has at least 2 gigabytes (GB) plus 400 megabytes (MB) for every terabyte (TB) of data that the Chunk Store must address.

▪	If you use a 32-bit platform, you are limited to a Chunk Store of 5 TB of unique data.

▪	If you use a 64-bit platform, you are limited to a Chunk Store of 15 TB of unique data.

Hardware requirements

Hardware requirements

The use of NetVault SmartDisk in a production environment is only supported when run on a physical machine.

The NetVault SmartDisk server must meet the following hardware requirements:

•

Processor requirements: Processor requirements vary based on the required NetVault SmartDisk Deduplication Rate (the rate at which NetVault SmartDisk deduplicates data) — the higher the Deduplication Rate requirements, the higher the CPU requirements for the machine where NetVault SmartDisk software is installed. Generally, the NetVault SmartDisk machine should be equipped with two dual-core processors.

The NetVault SmartDisk Deduplication Rate must be greater than or equal to the Ingest Rate to ensure that the deduplication process completes during the backup window or before the next weekly backup window begins. For more information, see Deduplication Rate < Ingest Rate.

•	Memory requirements:

Required minimum: 2 GB

Recommended minimum: An extra 400 MB per 1 TB of NetVault SmartDisk-unique data

Example

10 TB of NetVault SmartDisk Unique Data

2 GB + (400 MB * 10) = 2 GB + 4000 MB = 6 GB

•	Network requirement for all NetVault SmartDisk Instances: TCP/IP name resolution. After the machine that hosts the NetVault SmartDisk software has been identified, verify that the machine can resolve its own host name.

•	Storage Pool requirements: For Storage Pool requirements based on whether your goal is simplified management or optimal performance, see Defining a NetVault SmartDisk Storage Pool strategy.

Authentication requirements

Authentication requirements

•	Administrator account for installation: Administrator credentials are only required for use during the installation process, removal process, and, if necessary, manually restarting the NetVault SmartDisk Services.

•

NetVault SmartDisk Non-privileged Group and User: Security group with full NetVault SmartDisk configuration and monitoring rights. You are not required to create the non-privileged user before installation. You can enter the applicable information during the installation process. The installer verifies that the account meets all applicable system requirements before continuing with the installation process.

•

UNC path and credentials if using a network share on Windows: You can specify a path that includes a network share, whether it is mapped or using Universal Naming Convention (UNC). To do so, the parent directory of the target directory must exist — the target directory does not have to exist yet — and you must have the access credentials.

Important notes regarding Windows and the Non-Privileged User

The NetVault SmartDisk installer grants read- and write-access permission to the specified non-privileged user during the installation process. This access, which lets NetVault SmartDisk report Windows® Events, only applies to the Application log.

If you change the non-privileged user by using smartdisk password, the same rights are granted to the new user. The rights are retained for the original user because the original user might be assigned to multiple services on the same system. For the same reason, this access is also retained if you remove NetVault SmartDisk.

The modified registry key is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ Eventlog\Application

Therefore, if you know that a non-privileged user is not needed for other services, manually update the registry key and user account.
