vRanger 7.8 - Installation/Upgrade Guide

System requirements and compatibility

Requirements for the vRanger machine

To maximize application performance, and to ensure error-free operation, you must ensure that the machine on which vRanger is installed meets the requirements as documented in this topic.

Requirements for the vRanger machine are divided among these topics:

•	Minimum hardware requirements

•	Supported operating systems for installation

Review each of these topics thoroughly before installing vRanger.

 

NOTE: For LAN-free and HotAdd installation requirements, see Physical backup and restore.

Minimum hardware requirements

The minimum hardware requirements to run vRanger can vary widely based on several factors. Therefore, you should not do a large-scale implementation without first completing a scoping and sizing exercise.

vRanger: physical machine

The following describes the hardware recommendations for the vRanger physical machine:

 

Table 1. Requirements for a installing vRanger on a physical machine

CPU	Any combination equaling four cores of CPUs are recommended. Example one quad-core CPU; two dual-core CPUs.
RAM	4 GB RAM is required.
Storage	At least 4 GB free hard disk space on the vRanger machine.
HBA	For LAN-free, Quest recommends that you use two HBAs — one for read operations and one for writing.

vRanger: virtual machine (VM)

The following describes the hardware recommendations for using vRanger in a VM:

 

Table 2. Requirements for a installing vRanger on a virtual machine

CPU	Four vCPUs.
RAM	4 GB RAM is recommended.
Storage	At least 4 GB free hard disk space on the vRanger machine.

Requirements for physical backup and restore

When backing up from and restoring to a physical server, vRanger uses a client run on that server to perform backup and restore operations. To process the backup workload effectively, the physical server must meet the following requirements:

1

Windows 2008 R2 SP1 requires Windows Management Framework 3.0. Refer to Known Issue VR-177 in the vRanger Release Notes for more information.

2

The Windows Storage Server edition is not supported as an installation platform for vRanger.

Before installing vRanger on Windows Server 2012 R2, the updates listed in Additional required software must be installed.

Additional required software

In addition to a supported version of Windows® and a supported VMware® Infrastructure, you may need some additional software components, depending on your configuration.

•	Microsoft® .NET Framework: vRanger requires the .NET Framework 4.5. The vRanger installer installs it if not detected.

•	SQL Server: [Optional] vRanger utilizes two SQL Server® databases for application functionality. vRanger can install a local version of SQL Express 2014 SP3 or you can choose to install the vRanger databases on your own SQL instance.

•	Windows PowerShell 3 or above.If you are installing vRanger on Windows 2008 R2 SP1, you will need to install Windows PowerShell 3 or above before installing vRanger

•	vRanger virtual appliance (VA): The vRanger VA is a small, pre-packaged Linux® distribution that serves as a platform for vRanger operations away from the vRanger server. vRanger uses the VA for the following functions:

▪	Replication to and from VMware® ESXi™ hosts.

▪	File-level restore (FLR) from Linux machines.

▪	Optionally for backups and restores.

•	Updates for Windows Server 2012 R2: Before installing vRanger on Windows Server 2012 R2, ensure that the Windows updates listed below are installed:
