Microsoft has released some documents to accompany their TechEd 2012 sessions on Continuous Availability.
Windows Server 2012 contains a set of continuously available storage solutions that provide a cost effective alternative to an expensive storage area network (SAN) without sacrificing availability and performance. These solutions are targeted towards traditional information worker workloads and application workloads, and they span the scalability and price point needs for different market segments. Systems go from entry-level solutions to scale-out solutions with up to 400 drives. These solutions are based on software that is developed by several teams at Microsoft, hardware that is already in the market, and hardware that is being developed in cooperation with industry partners. These documents supplement the Microsoft TechEd 2012 sessions related to continuous availability. They introduce the new and enhanced features of Windows Server 2012 and cover topics such as Scale-Out File Server, Cluster-Aware Updating, SMB 3.0, and NIC Teaming.
