Recommended configuration:

  • 100 GB of disk volume
  • 2 CPU cores
  • 8 to 16 GB RAM memory

Primary Disk Set example: two, 144 GB, 15K RPM SAS drives, RAID 1

The software installation requires 10GB 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 MediaAgent), see the corresponding system requirements pages.

For information on Input Output Operations per second (IOPs) requirements, see IOPs for CommServe Database Volumes.

Database Engine

Microsoft SQL Server 2012 with Service Pack 2 is automatically installed during the installation of the CommServe software. Later SQL Server service packs and updates must be installed manually. We recommend to maintain the SQL Server up-to-date with any important updates released by Microsoft. For other important recommendations, see Considerations for SQL Server 2012.

The CommServe also supports Microsoft SQL Server 2008 (including R2 Editions).

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.

In a clustered environment, SQL Server 2012 with the appropriate service pack must be installed and clustered prior to installing the CommServe software. The CommServe software automatically uses the default or the named instance created during the SQL Server installation.

Recommended SQL Server Settings

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

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 MB 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 20%

Service Accounts

For Service Accounts, use the same Local System account for each service and enable auto-start for SQL services.

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

Hardware Validation for CommServe Database

The CommServe database needs to be on a fast disk for optimal backup performance. Before setting up the CommServe, the storage volumes must be validated for high performance. This can be done using IO meter tool which measures the IOPs (Input Output Operations per second). For more information, see IOPs for CommServe Database Volumes.

Miscellaneous

Internet Explorer

Microsoft Internet Explorer (IE) version 8.0, 9.0

.NET Framework Requirements

.NET Framework 4.0 is automatically installed. Make sure to install the hotfix for this .NET version from the Microsoft Site to avoid future issues.

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 7.0 (on Windows 2008 only)
  • Microsoft Internet Information Services (IIS) Manager version 7.5
  • All components of Microsoft Internet Information Services (IIS) Manager version 7.0 should be installed on Windows 2008

CommServe Name

By default, the SnapProtect 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".

CommServe Database on CIFS

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

Recommendation for Using Virtual Machines

Memory

  • Allocate multiple virtual CPUs to a virtual machine, if the anticipated SQL Server workload can take advantage of all the virtual CPUs.
  • Memory page sharing and memory ballooning must be enabled on the virtual machine.

Storage

SQL Data files and log files must reside on different disks (different VMFS). It is recommended to place the log files on RAID 1+0 or RAID 1 disks.

Network

Make sure to use the VMXNET virtual network adapter and separate virtual switches, each connected to its own physical network adapter.

Java Runtime Environment (JRE)

The software supports Java 7, JRE version 1.7.0_17 or higher.

If version 1.7.0_17 or higher is available on the computer, the software uses the existing JRE software.

If the JRE version is lower than 1.7.0_17, or no JRE is available at all, you will be prompted to install JRE version 1.7.0_17.

Notes on CommServe Installation

The CommServe is a resource intensive application and should be installed on a dedicated server. Therefore, it is recommended that the CommServe not be installed on a computer running other applications, such as Microsoft Exchange Server, an Oracle database, etc. Additionally, CommServe installed on virtual machines generally perform at about 60% capacity compared to physical machines with similar configurations.

The software should not be installed on a compressed drive.

If you wish to install the CommServe on Microsoft Windows Small Business Server platforms, you must install the CommServe along with the Microsoft SQL Desktop Engine (MSDE). However, if you already have a CommServe with the SQL Desktop Engine and you want to upgrade to the SQL Enterprise edition, see SQL Server Edition Upgrade for step-by-step instructions.

The computer on which the software is installed must have a static IP address. The software does not support Dynamic Host Configuration Protocol (DHCP).

Installing on a VMware Environment

If installing the CommServe on a VMware virtual machine, consider the following recommendations for optimal performance:

  • The ESX Server hosting the virtual machine should be vSphere (4.0) or above.
  • Disable vMotion for the virtual machine and the storage.
  • The virtual machine on which the CommServe will be installed should have:
    • Minimum 2 64-bit vCPUs
    • Minimum 16 GB RAM
    • All VMware tools and utilities installed
  • Minimum bandwidth of 1 Gbps for data transfer.
  • The CommServe's SQL database should be configured on shared storage (such as a SAN or FAST disk).

Installing on a Hyper-V Environment

If installing the CommServe on a Hyper-V virtual machine, consider the following recommendations for optimal performance:

  • Hyper-V Server 2008 R2 with Service Pack 1 (or higher) should be used to host the virtual machine.
  • The virtual machine on which the CommServe will be installed should have:
    • Minimum 4 64-bit vCPUs
    • Minimum 16 GB RAM
    • All Hyper-V Integration tools installed using the latest versions
  • A fast and dedicated storage as well as network interfaces for optimal performance of the CommServe SQL database.

Notes on Combined Installations

You will often install more than one module (For example, CommServe, MediaAgent, Client) on a single computer so that it can perform two or more functions. For example, you may want to back up the file system of a MediaAgent; hence, you would install both the MediaAgent and client software on that computer.

When you combine two or more functions on a single computer, the storage resources required to support the software for that computer are not essentially cumulative. This is because modules share some of the same software. As a result, combined installations require about 30 MB less disk space than installations where the software resides on separate computers.
