Announcing the System Center Capacity Planner Tool *Beta* Models for WSS 3.0 and SharePoint Server 2007
I'm excited to share information about a new beta capacity planning tool built by the solution accelerator team with the SharePoint team. This new capacity planning tool based on System Center Capacity Planner has two new models. These models based on WSS 3.0 and MOSS 2007 are not perfect. They are designed to fit into the System Center Capacity Planner framework. The tool is designed to provide you with some ideas and help you figure out early planning and design ideas. It should not be seen as a replacement for a good consultant or experienced architect to help you design the topology and layout of your systems. Especially for large and complex deployments the tool should be seen as a simple design tool to provide some suggestions. To be honest with you in early versions we started with 1 million users and 50TB, but found some of the large results to be misleading. Beta limits for these models are at 100K users and 2 TB to help provide estimates that we can more easily compare with existing and common deployments. These limits in the tool should not be seen as farm limits as they are arbitrary limits in the tool. Deployments with more than 2TB and more than 100K should really involve experienced consultants and not rely on a simple capacity tool alone. The larger and more complex the environment the less likely the results will address the needs of the environment. SharePoint deployments can be one scaled up server with a single web app with one large document library to a large spread out my site deployment for example. Information architecture and database, disk configuration, storage designs are all NOT part of the model and were not addressed with the test.
The tool is give you some general idea... designed to evaluate number of users, basic concurrency with requests per second, authentication (anonymous or NTLM/AD), internet or intranet, with configurable transaction based (i.e. light/average/heavy) user profiles. There are a number of hard coded assumptions around average file sizes, and home page sizes. The SCCP framework provides some limited hardware configurations that can be used.
