Installing NetVault SmartDisk: an overview

Installing NetVault SmartDisk involves the following main steps:

•
Verifying that the system requirements are in place.
•
Installing the software.
•
Installing the license key.
•
Updating the Storage Pool structure, if applicable.
•
Adding the NetVault SmartDisk Devices to your backup product.
•
Protecting the NetVault SmartDisk identity.

System requirements

The following sections identify the prerequisites that must be met before you install NetVault SmartDisk:

•
Software requirements
•
Hardware requirements
•
Authentication requirements

Software requirements

NetVault SmartDisk has the following software requirements:

•
Windows: NetVault SmartDisk has the following requirements on 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 TB of data that the Chunk Store must address. If you use a 32-bit platform, you are limited to a Chunk Store of between 1.8 TB and 2.5 TB of unique data, depending on the OS.
 
* 
IMPORTANT: If you intend to use deduplication, Quest recommends that you use the 64-bit (Pure64) versions of NetVault SmartDisk instead of the 32-bit or Hybrid versions whenever possible. Deduplication is memory-intensive; 32-bit memory allocation is limited, and capacity varies by OS and by usage.
•
Linux: NetVault SmartDisk has the following library requirements on Linux. Installation might fail if these packages are not installed on the system. For instructions on installing the required packages, see the relevant OS documentation.
•
Asynchronous I/O Library: Depending on the Linux distribution, verify that the libaio.so.1 package is installed in the following directory:
•
32-bit OS: /lib or /usr/lib
•
64-bit OS: /lib64 or /usr/lib64
Some distributions of Linux do not install the Asynchronous I/O Library package by default. If necessary, install this package.
•
Standard C++ Library
•
NetVault SmartDisk Linux x86_Hybrid and Linux IA64 Builds: Verify that the libstdc++.so.6 package is installed in the /usr/lib directory. If NECESSARY, install the Standard C++ Library package.
•
NetVault SmartDisk Linux x86_Pure64 Build: Verify that the libstdc++.so.5 package is installed in the /usr/lib64 directory. If necessary, install the Compatibility Standard C++ Library package.

Hardware requirements

NetVault SmartDisk has the following hardware requirements:

•
Deduplicated NetVault SmartDisk Instances: If the NetVault SmartDisk Deduplication Option is enabled, verify that the following requirements are met:
•
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 processor requirements for the machine where NetVault SmartDisk software is installed.
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 Calculating the required number of NetVault SmartDisk Instances.
•
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
For more information, see Calculating the required number of NetVault SmartDisk Instances.
•
Nondeduplicated NetVault SmartDisk Instances: If the NetVault SmartDisk Deduplication Option is not enabled, verify that the following requirements are met:
•
Processor requirements: Use a machine with a 24-to-36-month-old Intel Core 1, AMD Athlon, or Intel Celeron processor. Quest recommends that you use faster processors for best performance.
•
Memory requirements: The minimum requirement is 512 MB.
•
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 Storage Pool strategy.

For additional information, see the Quest NetVault Backup Compatibility Guide.
