Converged fabric and multi-tenancy pose new challenges in the data center where businesses are required to provide predictable network performance and SLAs. Today, a common solution is costly hardware overprovisioning and complex wiring. In this session, we will describe how Windows Server 8 enables data centers to use QoS and DCB-capable hardware to guarantee network bandwidth to a service. Because Windows Server 8 provides predictable network performance in a converged fabric environment, businesses will be able to virtualize and consolidate network I/O intensive workloads on a single 10GbE NIC thereby reducing costs and improving service. Partners, through familiar PowerShell and WMI interfaces, will be able to integrate these QoS features to provide a better service on Windows Server 8.
