Team Foundation Server Dogfood Update

On Friday, Brian Harry blogged an update about our (Developer Division) dogfooding of Team Foundation Server over the last month, which includes lessons learned about our SAN usage and the latest stats. 

The big learning (for me) in the past month or two has been around SAN configuration and performance. A month or so ago we started getting event log errors on our SQL Server during peak load times saying that some I/O operations were taking more than 15 seconds to complete. This has been coincident with us seeing some performance degradation for end users during these peak times.
