Ironically I'm almost the last to blog it, but the SCCP team is really happy to announce the release of System Center Capacity Planner 2007. You can get it now, it's totally free, and it'll help you size deployments for Exchange Server 2007. But wait! There's more. The fabulous Solutions Accelerator team have released plug-in models for SCCP 2007 that let you do capacity-planning for Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 as well. And in the near future we'll be releasing a model for System Center Operations Manager 2007. Did I mention that these are all free??
A big thankyou to everyone involved who made this release possible. I'd especially like to thank everyone involved with the Exchange model - the free publicity doesn't hurt either :)
As always, your first port of call for feedback and questions about SCCP 2007 - after the FAQ, of course - is our web forum.
