Hardware and Software Requirements

Hardware requirements:

Intel or compatible platform

Pentium 166 MHz or higher (Pentium II, Pentium III and compatible)

32MB RAM (minimum for Desktop Engine), 64MB RAM (minimum for all other editions) 128 MB RAM or more recommended

270MB (full installation), 250MB (typical), 95MB (minimum), 44 MB (Desktop Engine) plus Analysis Services: 50 MB minimum and 130 MB typical and 80MB for the English Query

By the way, there is no hardware restriction on the processor speed (you can run SQL Server 2000 on the Pentium with minimum mhz), I have checked it on Pentium 120, but don't use this hardware on production server, only for the test purpose.
SQL Server 2000 will run under Windows 98, Windows NT Server 4.0 with Service Pack 5 or later, Windows NT Workstation 4.0 with Service Pack 5 or later and Windows 2000 (all editions).
SQL Server 2000 also requires Internet Explorer 5.0 or later, as it is required for Microsoft Management Console and HTML Help. Internet Explorer is not required to be the default browser and a minimal install is sufficient.

SQL Server Editions

There are three main SQL Server 2000 editions:

Personal Edition

Standard Edition

Enterprise Edition

Personal Edition can works on the Windows 98, Windows NT Server 4.0 with Service Pack 5 or later, Windows NT Workstation 4.0 with Service Pack 5 or later and on the all editions of Windows 2000. This edition is related to SQL Server 7.0 Desktop Edition


This edition has some restrictions:

maximum 2 CPU

no Distributed Partitioned Views

no Log Shipping

no Parallel DBCC

no Parallel index creation

no Failover clustering

no publishing for transaction replication

maximum 2Gb RAM

Standard Edition can works on the Windows NT Server 4.0 with Service Pack 5, Windows NT Server 4.0 Enterprise Edition and on the Windows 2000 Server/Advanced Server/DataCenter.
This edition has the following restrictions:

maximum 4 CPU (up to 8 CPU on the Windows NT Enterprise Edition)

no Distributed Partitioned Views

no Log Shipping

no Parallel index creation

no Failover clustering

maximum 2Gb RAM

Enterprise Edition can works on the Windows NT Server 4.0 with Service Pack 5, Windows NT Server 4.0 Enterprise Edition and on the Windows 2000 Server/Advanced Server/DataCenter.
This edition can uses:

up to 32 CPU on the Windows 2000 DataCenter up to 8 CPU on the Windows 2000 Advanced Server and on the Windows NT Server 4.0 Enterprise Edition up to 4 CPU on the Windows NT Server 4.0 and on the Windows 2000 Server

up to 64Gb RAM on the Windows 2000 DataCenter up to 8 Gb RAM on the Windows 2000 Advanced Server up to 4 Gb RAM on the Windows 2000 Server up to 3 Gb RAM on the Windows NT Server 4.0 Enterprise Edition up to 2 Gb RAM on the Windows NT Server 4.0

Distributed Partitioned Views

Log Shipping

Parallel index creation

Failover clustering

There are also Developer Edition, Desktop Engine, SQL Server CE and Evaluation Edition.
The Developer Edition can be used by developer to create and debug stored procedures, triggers used by client applications. This edition comes with its own compact disc and can be upgraded to SQL Server 2000 Enterprise Edition.
The Desktop Engine has no graphical user interface and is related to the MSDE, not to the SQL Server 7.0 Desktop Edition. The size of Desktop Engine databases cannot exceed 2 GB. The Desktop Engine can use maximum 2 CPU.
The SQL Server CE edition can works only on the Microsoft Windows CE, so it has all restrictions of this operation system (can use only 1 CPU, no Parallel index creation, no Full-Text Search and so on).
The Evaluation Edition can be used only for the test purposes to learn more about the new features and enhancements and should be uninstalled after a 120-day evaluation period.

Installation Types

SQL Server Setup offers three installation types in the Setup Type dialog box, when you install the SQL Server 2000 Enterprise Edition, SQL Server 2000 Standard Edition, or SQL Server 2000 Personal Edition, There are three installation types:

Typical

Minimum

Custom

Typical

The Typical installation option is recommended for most users. This is the default installation options. The Typical option installs the upgrade tools, replication support, client management tools, online documentation and so on.

Minimum

This installation can takes only 95Mb on your hard drive and contains the minimum configuration necessary to run SQL Server.
There are no upgrade tools, full-text search, client management tools, online documentation, development tools and code samples.
Microsoft recommends this installation for users who have computers with minimum available disk space.

Custom

This type of installation allows you to change any or all of the default options. Custom installation is recommended for advanced users. You can install code samples, choose to install the development libraries, network libraries, code samples and so on.

Testing an installation

There are several ways to test SQL Server 2000 installation. When the installation is complete, you can verify SQL Server installation with osql (or isql) utility. This is the description: 1. Start MSSQLServer service.
You can start MSSQLServer service by entering from a command prompt:

net start mssqlserver

or by run SQL Server Service Manager and start MSSQLServer service manually.
2. Run osql utility.
Once the server is running, type the following command-line options:

OSQL -Usa -P

If successful, this osql prompt appears:
1>
Now you can verify SQL Server 2000 installation by entering this simple query:

SELECT @@SERVERNAME GO

If successful, this query returns the name of the server on which SQL Server 2000 is running. Now you can exit by typing exit command.
