This talk will appeal to Virtual Data Center Managers, Database Server administrators, and those that are seeking a fundamental understanding of NFSv4.1 with pNFS. It will cover the four key reasons to start working with NFSv4.1 today; explain the storage layouts for parallel NFS; NFSv4.1 Files, Blocks and T10 OSD Objects; and improvements in security. We’ll conclude the session with use cases for grid, database access, enterprise and desktop virtualization.

NFSv4 has been a standard file sharing protocol since 2003, but has not been widely adopted. Yet, NFSv4 improves on NFSv3 in many important ways. In this white paper, we explain the how NFSv4 is better suited to a wide range of datacenter and HPC use than its predecessor NFSv3, as well as providing resources for migrating from v3 to v4. And, most importantly, we make the argument that users should, at the very least, be evaluating and deploying NFSv4.1 for use in new projects; and ideally, should be using it wholesale in their existing environments.
The Fibre Channel (T11.3) standards committee developed a Standard called Fibre Channel over Ethernet (FCoE). The FCoE standard specifies the encapsulation of Fibre Channel frames into Ethernet Frames and the amalgamation of these technologies into a network fabric that can support Fibre Channel protocols and other protocols such as TCP/IP, UDP/IP etc. A “Direct End-to-End” FCoE variant has been accepted for the next version of the Standard The tutorial will show the Fundamentals of these FCoE concepts and describe how they might be exploited in a Data Center environment.

Since the earliest days of data networking, congestion control and management have been a major effort to ensure the best throughput. Years ago we had technologies such as Frame Relay Forward Explicit Congestion Notification (FECN) and Backward Explicit Congestion Notification (BECN), and others to achieve simple and effective methods of congestion notification and avoidance.

NFSv4 and the minor versions that follow it are designed to address many of the issues that NFSv3 poses. While adequate for many purposes and a familiar and well understood protocol, NFSv3 has become increasingly difficult to justify.
With the release of vSphere 4.1, VMware has added support for 10GbE iSCSI adapters that simplify deployment of iSCSI connectivity for virtualized servers. iSCSI adapters present separate network and storage devices to the ESX hypervisor that can be managed using the VMware vSphere client.
This paper focuses on an overview of the important issues that should be considered while migrating from an NFSv3 to NFSv4 environment. Throughout, there are practical suggestions (Action:) about what to look out for.
