South Pacific Web Mapping

Microsoft has released some new documentation for a very efficient way of swapping to a mirrored cluster (SQL level mirroring of the content DB)  while taking the primary cluster down for maintenance.

This could be particularly handy when you have a DR instance of MOSS 2007 which you want to serve your content of while upgrading/maintaining your production environment.

I have used SharePoint for storing and managing GIS content together with the Google maps API presentation layer and it works great, allowing a full blown content management environment with Google’s front-end scalability.

this functionality is supported from SP2 onwards and requires a separate route for each web farm(prod/DR)
