System Requirements: VMM Database in System Center 2012 and in System Center 2012 SP1

Updated: July 31, 2014

Applies To: System Center 2012 - Virtual Machine Manager, System Center 2012 SP1 - Virtual Machine Manager

This topic provides information about the system requirements for the SQL Server-based database for System Center 2012 – Virtual Machine Manager and for VMM in System Center 2012 SP1.

If you are using Software Defined Networking (SDN) in VMM, all networking information is stored on the VMM database. Because of this, you might want to consider high availability for the VMM database, using the following guidelines:

  • Failover clustering is supported and is the recommended configuration for availability within a single geographical area or datacenter. For more information, see AlwaysOn Failover Cluster Instances (SQL Server).

  • Use of AlwaysOn Availability Groups in Microsoft SQL Server in asynchronous-commit availability mode is not recommended.

    If you use AlwaysOn Availability Groups, and you are running an asynchronous-commit availability mode, the replica of the database can be out of date for a period of time after each commit. This can make it appear as if the database were back in time which might cause loss of customer data, inadvertent disclosure of information, or possibly elevation of privilege.

  • You can use AlwaysOn Availability Groups in Microsoft SQL Server in synchronous-commit availability mode as a configuration for remote-site availability scenarios. For more information, see Overview of AlwaysOn Availability Groups (SQL Server) and Getting Started with AlwaysOn Availability Groups (SQL Server).

Database hardware requirements

The following tables provide the minimum and recommended hardware requirements for the System Center 2012 – Virtual Machine Manager (VMM) database. These requirements are based on the number of hosts that you manage. For best performance, we recommend that you store the VMM database on a disk other than the disk on which the operating system is installed.

Managing up to 150 hosts

 

Hardware component Minimum Recommended

Processor

Pentium 4, 2.8 gigahertz (GHz)

Dual-core 64-bit, 2 GHz

RAM

2 gigabytes (GB)

4 GB

Hard disk (on which the operating system is installed)

80 GB

150 GB

Hard disk free space (on which the database is stored)

20 GB

50 GB

Managing more than 150 hosts

 

Hardware component Minimum Recommended

Processor

Dual-core 64-bit, 2 GHz

Dual-core 64-bit, 2.8 GHz

RAM

4 GB

8 GB

Hard disk (on which the operating system is installed)

150 GB

200 GB

Hard disk free space (on which the database is stored)

50 GB

75 GB

Supported versions of SQL Server

To host the VMM database, VMM supports the following versions of Microsoft SQL Server software.

 

SQL Server for System Center 2012 – Virtual Machine Manager Service pack Editions

SQL Server 2008 R2 (64-bit)

Service Pack 2 or earlier

Standard, Enterprise, and Datacenter

SQL Server 2008 (64-bit)

Service Pack 2 or Service Pack 3

Standard and Enterprise

 

SQL Server for VMM in System Center 2012 SP1 Service pack Editions

SQL Server 2008 R2

Service Pack 1 or Service Pack 2

Standard, Enterprise, and Datacenter (64-bit)

SQL Server 2012

With or without Service Pack 1

Standard and Enterprise (64-bit)

Additional requirements and information

  • You must use an instance of SQL Server that allows case-insensitive database objects.

  • The name of the computer on which SQL Server runs cannot exceed 15 characters in length.

  • When you install SQL Server, select the Database Engine Services and Management Tools - Complete features.

  • If the VMM management server and the computer on which SQL Server runs are not members of the same Active Directory domain, a two-way trust must exist between the two domains.
