Verify that your Windows environment meets the system requirements for the CommServe server.
Operating System
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.
For new installations of Commvault version 11.24 and later versions, Microsoft Windows Server 2012 is not supported. New installations of Commvault version 11.24 and later versions use MS SQL Server 2019, which requires a minimum of MS Windows Server 2016. Commvault upgrades are still supported.
Beginning with Commvault version 11.34 (Commvault Platform Release 2024), Microsoft Windows Server 2012 and 2012 R2 will not be supported for Commvault upgrades because Microsoft has ended mainstream support for these Windows versions.
Windows 2012 and 2012 R2 clients will continue to be supported.

Note
Beginning Commvault Platform Release 2022E, Windows Server 2012 and Windows Server 2012 R2 are no longer supported. For more information, see Announcements.
Hardware
For the hardware requirements for the CommServe sever, installed on either physical or virtual machines, see 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 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.

Cumulative Update 15 Cumulative Update 15 + GDR |
Microsoft SQL Server 2022 is not installed during a fresh CommServe server installation. You can only upgrade an existing SQL server standard installation on the CommServe server to Microsoft SQL Server 2022. For upgrade instructions, see Supported version and edition upgrades (SQL Server 2022). |

Microsoft SQL Server 2019 |
Enterprise, Standard, and Express Editions |
Standard edition only with Feature Release 11.24 and more recent releases. |
Cumulative Update 28, Cumulative Update 28 + GDR |
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 pre-installing MS SQL Server, see Pre-Installing the Microsoft SQL Server Software on a Non-Cluster Environment.
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 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.
CommServe Name Cannot Be "CommCell"
By default, the Commvault software uses the name of the server computer (where the CommServe component is installed) as the CommServe name. During the installation of the CommServe component, the software also allows you to specify a different CommServe name.
Caution
The CommServe name cannot be "CommCell". If you change the CommServe name during installation, do not change it to "CommCell".
Software That Is Automatically InstalledFor a complete list of third party applications that are automatically installed, see Third Party Applications Installed by the Commvault Installer.
.NET Framework
Microsoft .NET Framework 4.6.2 is required and is automatically installed.
Internet Information Services
By default, the Web Server and Web Console packages are installed with the CommServe computer. To install this software, Microsoft Internet Information Services (IIS) must be enabled on the CommServe computer and must meet the following requirements:
-
Internet Information Services Manager version 10.0 (on Windows 2016 only)
-
Internet Information Services Manager version 8.0 or 8.5 (on Windows 2012 only)
-
Internet Information Services Manager version 7.5
Java SE Platform
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
Starting with Service Pack 18, Microsoft Visual C++ Redistributable 2017 (vcredist2017.exe) is automatically installed.
If a computer does not have the most recent 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. The updates are not required on the most recent Windows operating system versions, such as Microsoft Windows 10 and Microsoft Windows Server 2016, because these versions have the Universal C Runtime already installed.
