To briefly summarize what this tool can do for you, here is a copy/paste of the Capabilities section from the SharePoint Capacity Planning Tool Reference 1.0:
SCCP supports capacity planning for Microsoft Exchange Server 2003 and Microsoft Operations Manager (MOM) 2005 and 2007. This existing capacity modeling capability made SCCP the logical choice as the base software program to use in developing the SharePoint Capacity Planning Tool. The tool utilizes the proven functionality, capabilities, and easy-to-use interface provided by SCCP to generate a topology that reflects the needs of your enterprise.
This version of the SharePoint Capacity Planning Tool provides specific types of assistance for your planning process:
· In-scope capabilities. The tool is designed to assist you in planning the following elements of a WSS/MOSS installation:
· Deployment of WSS 3.0 on servers running Windows Server 2003 SP2.
· Deployment of MOSS 2007 on servers running Windows Server 2003 SP2.
· Determining storage requirements for MOSS.
· Ensuring high-availability needs are met.
· Planning for scalability and expansion of existing installations.
· Out-of-scope capabilities. Several areas that are beyond the scope of the tool include:
· Modeling memory usage. SCCP does not model memory usage.
· Upgrade scenarios for WSS and MOSS. The tool models only the latest version of WSS 3.0 and MOSS 2007.
· Self discovery of existing WSS/MOSS installations. The tool models only green-field and previously saved models.
· Deployment migration from competitor products. The tool models only WSS and MOSS.
· Real-time customer usage profiling. SCCP does not deploy agents into your server farm to monitor usage patterns in existing SharePoint installations. This may be addressed in future versions.
· Virtualized WSS/MOSS deployment. The tool assumes that you are doing capacity planning for a production environment and are using physical server boxes to deploy your SharePoint farm.
· Disaster recovery scenarios. Disaster recovery scenarios introduce levels of complexity that make efficient modeling prohibitive.
· Side by side installations. The tool models only new installations of the latest WSS and MOSS releases. Incremental upgrades involving server farms with multiple versions of WSS or MOSS are not handled.
· Extranet installation. Authentication complexity precludes implementing extranet modeling.
· E-mail integration: Exchange Server integrated with SharePoint. E-mail integration may be included in a future release.
· Microsoft Excel® services. Excel services may be included in a future release.
· High-end scenarios. The tool does not model high-end scenarios such as multi-terabyte Web applications or multiple Web applications.
· Authentication methods other than NTLM and Anonymous.
