CommServe Server: System Requirements

The following requirements are for the CommServe server.

Best Practice

Important

Use the most recent version of the operating system that is listed. The Commvault software fully supports the most recent version of an operating system, until the vendor ends support. More recent versions of the Commvault software might not install on operating systems that are not supported by the vendor anymore. For information about the support lifecycle of an operating system, contact the vendor.

Operating Systems

Windows
Microsoft Windows Server 2022 Editions
Microsoft Windows Server 2019 Editions
Microsoft Windows Server 2019 Core Editions
Microsoft Windows Server 2016 Editions For more information, see Considerations for Microsoft Windows Server 2016.

Cluster Support

You can install the software on a cluster, if clustering is supported by the operating system. For information about supported cluster types, see Support for Cluster Configuration.

Processor

All Windows-compatible processors are supported

Hardware Specifications

The hardware requirements for CommServe installed on either physical or virtual machines is explained in Hardware Specifications for CommServe.

Note

The software installation requires 10 GB of disk space on the operating system drive. This space is used for temporary files copied during the installation or upgrade of the CommServe and Microsoft SQL Server software.
For hard drive requirements details of other components (such as the Hardware Specifications for Deduplication Mode), see the corresponding system requirements pages.

Database Engine

The Microsoft SQL Server application that is installed on the computer must be dedicated to support the software and cannot be shared by other applications.

Microsoft SQL Server Build	Supported Edition	Default with Fresh CommServe Software	Certified Service Pack/ Cumulative Update	Supported Feature	Notes
Microsoft SQL Server 2019	Enterprise, Standard, and Express Editions	Feature Release 11.24 and more recent releases	Cumulative Update 15	Features Supported by the Editions of SQL Server 2019
Microsoft SQL Server 2017	Enterprise, Standard, and Express Editions		Cumulative Update 22 (RTM-CU22)	Features Supported by the Editions of SQL Server 2017
Microsoft SQL Server 2016	Enterprise, Standard, and Express Editions	Feature Release 11.16 and more recent releases	Service Pack 3	Features Supported by the Editions of SQL Server 2016	If you set up the CommServe server in a virtual environment and use Microsoft SQL Server 2016, set the socket count to 4 and the core count to 4.

Later MS SQL Server service packs and updates must be installed manually. You must update MS SQL Server with any important updates released by Microsoft.

For information about scalability (such as CPU, socket, and memory limits), performance, and other supported features, see "Editions and supported features of Microsoft SQL Server" on the Microsoft website.

Recommended SQL Server Settings

The database instance used by the software requires specific SQL server settings.

Note

For information about SQL Server on Linux, see Microsoft guidelines for SQL Server on Linux on the Microsoft website.

Using the SQL Management Studio, verify the SQL properties listed below.

SQL Memory Size

Access the server properties and navigate to the Memory page. The maximum server memory should be 50% of the physical memory available in the computer on which the software is installed.

Server Collation

Run the sp_helpsort system stored procedure, and verify that the server default collation has the following properties:

Character Set is 1252/ISO (default)
Sort Order is Dictionary order, and case is Insensitive
Unicode Collation includes General Unicode, case Insensitive, width Insensitive
SQL Server collation is SQL_Latin1_General_CP1_CI_AS

Temp Database Properties

Navigate to the tempdb database (under the Databases | System Databases node), and access its properties to verify the following:

The tempdb database has at least 100 GB of disk space. Depending on the components that you decide to install later, additional space may needed.
Click the Files page to check the autogrowth properties of the database files. The Enable Autogrowth option must be selected, and the file growth should be set to 10%.

For more information about the CommServe Server hardware requirements, see Hardware Specifications for the CommServe Server.

Service Accounts

For Service Accounts on non-clustered environments, use the domain administrator account or a gMSA (Group Managed Service Account). Alternatively, you can use the same Local System account for each service and enable auto-start for SQL services.

Note

gMSAs provide enhanced security.
Ensure that the gMSA is a part of the Domain Administrators group.

On clustered environments, use an account with administrator privileges (such as, a member of the Administrator local group of the computer or domain).

Note

For SQL Server 2014, the license is limited to 4 sockets or 16 cores, whichever is less or whichever comes first.
For SQL Server 2016, 2017, and 2019, the license is limited to 4 sockets or 24 cores, whichever is less.
For the SQL Server scheduler, use NUMAs for distributing or scheduling the SPID load.
For VMs that have more than 4 sockets, SQL Server uses only the first 4 sockets. This configuration is considered to be a bad configuration.
Each VM socket must have its own NUMA association for SQL Server Schedulers and for CPUs that have more than 4 sockets per NUMA.
SQL Server VMs must have matching, dedicated physical CPUs on the VM Host. For the best performance, the VMs must not be shared.
For a SQL Server VM used in the CommServe environment, I/O per second (IOPS) must be at least 150.

CommServe Database on CIFS

The CommServe SQL database is not supported on a CIFS share.

Miscellaneous

Internet Explorer

Microsoft Internet Explorer (IE) version 11.0

.NET Framework

The Microsoft .NET Framework 4.6 is required and is automatically installed.

Internet Information Services (IIS)

By default, the Web Server and Web Console packages are installed with the CommServe. To install this software, IIS must be enabled on the CommServe computer and meet the following requirements:

Microsoft Internet Information Services (IIS) Manager version 10.0 (on Windows 2016 only)
Microsoft Internet Information Services (IIS) Manager version 8.0 or 8.5 (on Windows 2012 only)
Microsoft Internet Information Services (IIS) Manager version 7.5

CommServe Name

By default, the Commvault software uses the name of the server computer (where the CommServe component is being installed) as the CommServe name. During the installation of the CommServe component, the software also allows you to specify a different CommServe name.

Note: The CommServe name cannot be "CommCell". If you change the CommServe name during installation, do not change it to "CommCell".

Java SE Platform

The software supports Java 11.

Java is installed automatically during the installation of this software. If you already have a system-installed Java version, the software installs another instance of the supported Java version in the software installation path.

All Commvault binaries (JAR files) are signed by SHA-256 Digest. To verify that the downloaded JAR files from Java webstart/netx.jar are not modified, use SHA 256.

Note

Commvault always updates the Java version with the most recent security updates, so that the components using Java do not have any vulnerabilities that are reported by the open source community. To manually upgrade the Java Runtime Environment (JRE) for the Commvault software, see KB article 57019.

Microsoft Visual C++ Redistributable 2017 is Automatically Installed

Starting in Service Pack 18, Microsoft Visual C++ Redistributable 2017 (vcredist2017.exe) is automatically installed. If a computer does not have the latest Windows updates, the installation of Microsoft Visual C++ Redistributable 2017 will fail in installing Universal C Runtime.

The following Windows updates must be installed to prevent the installation failure:

KB2919355

KB2939087

KB2975061

KB2999226

Updates are not required on latest Windows operating system versions, such as Microsoft Windows 10 and Microsoft Windows Server 2016, as these versions come with the Universal C Runtime already installed.

Disclaimer

Third-party maintenance (minor) releases or service packs that are supported by the Commvault software may not be listed in our System Requirements. When possible, Commvault provides information on any known issues related to these minor releases or service packs. In some cases, these minor releases or service packs affect how the Commvault software works. Commvault software may experience changes in functionality as the result of the third-party minor release or service pack. These changes are beyond the control of Commvault. Platforms that are supported in the current version of Commvault software may not be supported in earlier versions of the software. Contact your software provider to ensure that third-party minor releases or service packs are compatible with the Commvault software. Additional considerations regarding minimum requirements and End-of-Life policies from third-party vendors also apply.
