Planning for Performance and Scalability in Service Manager 2010
Updated: December 1, 2010
Applies To: System Center Service Manager 2010
This section describes general performance and scalability planning guidance for System Center Service Manager 2010. While Service Manager is built to meet a performance standard on minimum recommended hardware, the hardware requirements for your specific scenario may be higher or lower than the generalized guidelines presented here. Also presented here are considerations for both hardware and Service Manager software.
Service Manager is a 3-tiered application consisting of a database, a data access module, and a console.
Every deployment topology from the largest to smallest includes all three tiers, whether physically or virtually.
The smallest deployment topology supported requires 2 servers, either physical or virtual, and the largest will contain more than 4 servers.
Hosted on the servers are the Service Manager console and Service Manager database on the management server, the Self-Service Portal is usually hosted on another server, and the data warehouse management server hosts the Service Manager data warehouse.
Service Manager Sizing Helper Tool
The Service Manager Sizing Helper tool can help you size the hardware and software pieces that you will later deploy with more detail contained this guide. The tool is included in the Service Manager job aids documentation set. (http://go.microsoft.com/fwlink/?LinkId=186291). Specifically, the sizing tool:
Helps to give you an idea of the type of hardware such as individual computers, CPU, free and used hard drive space, and RAID level that is needed for different usage and deployment scenarios. Usage is indicated by the number of configuration items in the Service Manager database, work items per month, and days of data in the data warehouse.
Provides topology diagrams for each scenario, which map the hardware to scenarios such as single physical server, 2 server, 4 server, and more than 4 servers.
Helps you to calculate free and used hard drive space needed for a scenario, based on what you input. The calculation is an estimate, not a fixed value that you must meet.
