Hardware and Software Requirements for Installing SQL Server 2005

Updated: 17 November 2008

The following sections list the minimum hardware and software requirements for running Microsoft SQL Server 2005.

ms143506.note(en-US,SQL.90).gifNote:
Requirements for running SQL Server on the 32-bit platform are different from requirements for the 64-bit platform.

Monitor

SQL Server graphical tools require VGA or higher resolution: at least 1,024x768 pixel resolution.

Pointing Device

A Microsoft mouse or compatible pointing device is required.

CD or DVD Drive

A CD or DVD drive, as appropriate, is required for installation from CD or DVD media.

Cluster Hardware Requirements

On 32-bit and 64-bit platforms, eight-node cluster installations (that is, the maximum number of nodes supported by Microsoft Windows Server 2003) are supported. For more information on high availability solutions, see Configuring High Availability and Before Installing Failover Clustering.

Network Software Requirements

Network software requirements for the 64-bit versions of SQL Server 2005 are the same as the requirements for the 32-bit versions. Windows Server 2003, Windows XP, and Windows 2000 have built-in network software.

ms143506.note(en-US,SQL.90).gifNote:
SQL Server 2005 does not support the Banyan VINES Sequenced Packet protocol (SPP), Multiprotocol, AppleTalk, or NWLink IPX/SPX network protocols. Clients previously connecting with these protocols must select a different protocol to connect to SQL Server 2005.

Stand-alone named and default instances support the following network protocols:

  • Shared memory
  • Named pipes
  • TCP/IP
  • VIA

Note   Shared memory is not supported on failover clusters.

Internet Requirements

Internet requirements for both the 32-bit and 64-bit versions of SQL Server 2005 are the same. The following table lists the Internet requirements for SQL Server 2005.

Component Requirement

Internet software1

Microsoft Internet Explorer 6.0 SP1 or later is required for all installations of SQL Server 2005, as it is required for Microsoft Management Console (MMC) and HTML Help. A minimal installation of Internet Explorer is sufficient, and Internet Explorer is not required to be the default browser.

However, if you are installing client components only and you will not connect to a server that requires encryption, Internet Explorer 4.01 with Service Pack 2 is sufficient.

Internet Information Services (IIS)

IIS 5.0 or later is required for Microsoft SQL Server 2005 Reporting Services (SSRS) installations.

For more information about how to install IIS, see How to: Install Microsoft Internet Information Services. For more information about how to install IIS 7.0 on Windows Vista, see this Microsoft Web site.

ASP.NET 2.02

ASP.NET 2.0 is required for Reporting Services. When installing Reporting Services, SQL Server Setup will enable ASP.NET if it is not already enabled.

1Microsoft Internet Explorer 6.0 SP1 or later is required for SQL Server Management Studio, Business Intelligence Development Studio, and the Report Designer component of Reporting Services.

2For Reporting Services (64-bit) installations on 64-bit servers, the 64-bit version of ASP.NET must be installed. For Reporting Services (32-bit) installations on the 32-bit subsystem (WOW64) of a 64-bit server, the 32-bit version of ASP.NET must be installed. Reporting Services is not supported in side-by-side configurations on the 64-bit platform and on the 32-bit subsystem (WOW64) of a 64-bit server at the same time. For more information, see How to: Install 32-bit Reporting Services on a 64-bit Computer.

Software Requirements

SQL Server Setup requires Microsoft Windows Installer 3.1 or later and Microsoft Data Access Components (MDAC) 2.8 SP1 or later. You can download MDAC 2.8 SP1 from this Microsoft Web site.

SQL Server Setup installs the following software components required by the product:

  • Microsoft .NET Framework 2.0
  • Microsoft SQL Server Native Client
  • Microsoft SQL Server Setup support files
ms143506.note(en-US,SQL.90).gifNote:
SQL Server 2005 Express Edition does not install the ..NET Framework 2.0. Before installing SQL Server 2005 Express Edition, you must download and install the .NET Framework 2.0 from this Microsoft Web site.

If not already installed, SQL Server Setup installs each of these components separately; only the Microsoft SQL Server Setup support files are automatically removed when you uninstall SQL Server 2005. For more information on uninstalling this release, see How to: Uninstall an Existing Instance of SQL Server 2005 (Setup).

ms143506.note(en-US,SQL.90).gifNote:
The .NET Framework 2.0 Software Development Kit (SDK) is not installed by SQL Server 2005. The SDK contains documentation, a C++ compiler, and other tools that are useful when using the .NET Framework for SQL Server development. You can download the .NET Framework SDK from this Microsoft Web site.

After installing required components, SQL Server Setup will verify that the computer where SQL Server will be installed also meets all of the other requirements for a successful installation. For more information, see Check Parameters for the System Configuration Checker.

SQL Server 2005 failover clusters require Microsoft Cluster Server (MSCS) on at least one node of your server cluster. MSCS is only supported if it is installed on a hardware configuration that has been tested for compatibility with the MSCS software. For more information, see Before Installing Failover Clustering.

Cross-Language Support

For upgrades:

  • English-language versions of SQL Server can be upgraded to any localized version of SQL Server 2005.
  • Localized versions of SQL Server can be upgraded to localized versions of SQL Server 2005 of the same language.
  • Localized version of SQL Server cannot be upgraded to the English-language version of SQL Server 2005.
  • Localized versions of SQL Server cannot be upgraded to localized SQL Server 2005 versions of a different localized language.

All localized upgrades must follow supported upgrade paths. For specific information on supported upgrade paths, see Version and Edition Upgrades.

Additional cross-language support:

  • The English-language version of SQL Server 2005 is supported on all localized versions of supported operating systems.
  • Localized versions of SQL Server 2005 are supported on localized operating systems that are the same language as the localized SQL Server version.
  • Localized versions of SQL Server 2005 are also supported on English-language versions of supported operating systems through the use of Windows Multilingual User Interface Pack (MUI) settings. However, you must verify certain operating system settings before installing a localized version of SQL Server 2005 on a server that is running an English-language operating system with a non-English MUI setting. You must verify that the following operating system settings match the language of the localized SQL Server to be installed:
    • The operating system user interface setting
    • The operating system user locale setting
    • The system locale setting
    If these operating system settings do not match the language of the localized SQL Server, then you must correctly set these operating system settings as described in How to: Change Operating System Settings to Support Localized Versions.

Virtual Operating System Support

You can install SQL Server 2005 on Microsoft Virtual Server and on Microsoft Virtual PC on supported operating systems and hardware. For information about Virtual Server, see this Microsoft Web site. For information about Virtual PC, see this Microsoft Web site.

ms143506.Caution(en-US,SQL.90).gifCaution:
Do not install SQL Server 2005 on Microsoft Virtual Server or Microsoft Virtual PC on hardware that is not listed in the Hardware and Software requirements sections below.

4 SQL Server Evaluation Edition supports the same feature set as SQL Server 2005 Enterprise Edition.

ms143506.note(en-US,SQL.90).gifNote:
SQL Server 2005 software works on the hardware certified for use with the Microsoft Windows operating system. For more information about hardware certified for use with the Windows operating system, see this Microsoft Web site: Products Designed for Microsoft Windows - Windows Catalog and HCL.

Hard Disk Space Requirements (32-Bit and 64-Bit)

During installation of SQL Server 2005, Windows Installer creates temporary files on the system drive. Before you run Setup to install or upgrade to SQL Server 2005, verify that you have 2.0 GB of available disk space on the system drive for these files. This requirement applies even if you install all SQL Server components to a non-default (system) drive. Many files will be installed to the system drive, usually drive C:. For example, Setup log files will be written to the system drive, and can require 80 MB for a stand-alone installation, and more for a failover cluster installation. For more information, see File Locations for Default and Named Instances of SQL Server 2005.

Actual hard disk space requirements depend on your system configuration and the applications and features you choose to install. The following table provides disk space requirements for SQL Server 2005 components.
