Large Scale MSCS Deployment

I have a customer that provides Profiles (1TB) and user data (1TB) for 1800 User today on shared storage.

The customer wants to move this services to a Windows 2008 R2 Server with a Microsoft Cluster (Profiles and User Data). Does anyone have any reference architectures or customer references that are using MSCS for filesharing for +1800 users and over 2TB of data?

Thanks
