The Abstracts

Fibre Channel Over Ethernet (FCoE)
John Hufferd
Download

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.

Learning Objectives

  • The audience will gain a general understanding of the concept of using a Data Center type Ethernet for the transmission of Fibre Channel protocols. 
  • The audience will gain an understanding of the benefits of converged I/O and how a Fibre Channel protocol can share an Ethernet network with other Ethernet based protocols. 
  • The audience will gain an understanding of potential business value and configurations that will be appropriate for gaining maximum value from this converged I/O capability.

Convergence in the Data Center
Ahmad Zamer
Download

This session explores the trends driving convergence in the data center. It examines the potential for convergence and where it may take place from the perspectives of data center architecturem applications, and storage & networking technologies. The session will also discuss the need for more resilient L2 infrastructure and how it may be established. Finally, a review of deployment models for converged data center utilizing Lossless Ethernet, TRILL, FCoE and iSCSI will be provided.

Learning Objectives

  • Current trends in the data center are driving the need for convergence, which places special requirements on L2 infrastructure and server I/O channers 
  • Not all things will converge. Progress will be evolutionary and will come in stages requiring new technologies such as lossless Ethernet, FCoE, TRILL and L2 infrastructure enhancements that will lead to new data center architectures 
  • What to converge, how to do it and where to deploy convergence in the data center

pNFS, Parallel Storage for Grid Virtualization and Database Computing
Alex McDonald
Download

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

Tutorial Agenda

  1. agenda (the information below + core message)
  2. intro - nfs, one slide - soup to nuts
  3. nfsv4 (two slides on SHIP - Security, HighAvail, International and Performance + lead in to v4.1)
  4. the problem (virtualization acting like grids, vertical scaling, lower costs with commodity heads/controllers i.e. mid vs high-end) (two-three slides)
  5. nfsv4.1 ietf status, graphical depiction of nfsv4.1 + layout protocols (one-two slides)
  6. brief about layout's + operations (one-two slides)
  7. database access (NFSv4.1 – file delegations using host-flash, trunking and parallel storage) (two slides)
  8. enterprise virtualization (NFSv4.1 – directory delegations using host-flash, trunking, density, parallel storage) (two slides)
  9. desktop virtualization (NFSv4.1 – directory delegations using host-flash, trunking and parallel storage) (two slides)
  10. client/server status update CITI/UMICH/Open Solaris (one slide)
  11. summary/call to action (one slide on three takeaways)

Learning Objectives

  • Learn the four reasons to deploy NFSv4 today; a prelude to pNFS 
  • Understand the three storage layouts for parallel NFS; not just files, but blocks and objects too 
  • Uses cases for databases, enterprise and desktop virtualization

PCI Express Impact on Storage Architectures and Future Data Centers
Ron Emerick
Download

PCI Express Gen2 and Gen3, IO Virtualization, FCoE, SSD are here. Discussions about PCI Express Storage Devices – what are they? This session describes PCI Express, Single Root and Multi Root IO Virtualization and the implications on FCoE, SSD and impacts of all these changes on storage connectivity, storage transfer rates. The potential implications to Storage Industry and Data Center Infrastructures will also be discussed. What does the 2020 Data Center look like?

Learning Objectives

  • Knowledge of PCI Express Architecture, PCI Express Roadmap, System Root Complexes and IO Virtualization 
  • Expected Industry Roll Out of latest IO Technologies and required Root Complex capabilities. IO Virtualization connectivity possibilities in the Data Center (via PCI Express). 
  • Implications and Impacts of FCoE, SSD and PCI Express Storage Devices to Storage Connectivity. What does this look like to the Data Center?

iSCSI:  A Loss-less Ethernet Fabric With DCB
Gary Gumanow and Jason Blosil
Download

A look at different storage technologies and a brief look at each; benefits/tradeoffs, making the case for a SAN. Then looking at making your SAN a lossless, high-performance, predictable, resource for your business. Well look at the iSCSI and TCP/IP stack and how the new DCB protocol interacts with Ethernet. And lastly, I'll present some findings of using these technologies.

Learning Objectives

  • A comparison between three storage models; iSCSI, FC, and FCoE. Comparing all three to the OSI model. A discussion of the requirements for each layer of the networking stack. 
  • A look at the benefits that DCB can provide iSCSI, as a lossless Ethernet fabric. A review of performance and contention issues.
