BlogCadre just made the upgrade from Media Temple's shared server platform to their new "Grid Server" system.

New GS Features
Instead of a shared server, the GS system places all your data on an NFS server. There are apparantly several load-balanced front end web servers that then access this data from the common data location. Ben over at cuddletech has some more details on the Grid Server set up.

Read on for more info about the transition, including migration notes and my skepticism as to whether or not this service is even a good move. If you want the 5 second version: the transition is frightening with no staging process or backout plan, and the "upgrade" leaves us with half the bandwidth and the real potential for expensive new mystery charges.
