The speakers are Brian Johnson (Solutions Architect, Intel) and Jim Pinkerton (Windows Server Architect, Microsoft).

Pinkerton starts the session with a discussion of why Microsoft is able to speak to network virtualization via their experience with large-scale web properties (Bing, XBox Live, Outlook.com, Office, etc.). To that point, Microsoft has over 100K servers across their cloud properties, with >200K diverse services, first-party applications, and third-party applications. This amounts to $15 billion in data center investments. Naturally, all of this runs on Windows Server and Windows Azure.
So why does networking need to be transformed for the cloud? According to Pinkerton, the goal is to drive agility and flexibility for your business.
...
Pinkerton now takes over again, talking about VM density and the changes that have to take place to support higher VM density in private cloud environments (although I would contend that highly virtualized data centers are not private clouds). In particular, Pinkerton feels that SMB3 and SMB Direct (RDMA support) are important developments. According to Pinkerton, these protocols address the need for lower network and storage CPU overhead, higher throughput requirements, lower variances in latency and throughput, better fault tolerance, and VM workload isolation.
Pinkerton insists that using file sharing semantics is actually a much better approach for cloud-scale properties than using block-level semantics (basically, SMB3 is better than iSCSI/FC/FCoE). That leads to a discussion of RDMA (Remote Direct Memory Access), and how that helps improve performance. Standardized implementations of RDMA include iWARP (RDMA over TCP/IP) and RoCE (RDMA over Converged Ethernet). InfiniBand also typically leverages RDMA. In the context of private cloud, having the ability to route traffic is important; that's why Pinkerton believes that iWARP and RoCE v2 (not mentioned on the slide) are important.
That leads to a discussion of some performance results, and Pinkerton calls out incast performance (many nodes sending data to a single node) as an important metric in private cloud environments.
