Notes: Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here. IBM hardware products are manufactured from new parts, or new and serviceable used parts. Regardless, our warranty terms apply. All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved.

  12. Enterprise Computing Community – ECC 2009 What is FCoE ? • Fibre Channel over Ethernet (FCoE) • T11.3 FC-BB-5 standard under development • August adoption looks promising • Encapsulate Fibre Channel frames in Ethernet • Desire to converge on a single wire for storage & networking • Leverage years of effort on Fibre Channel Standards • Compatibility with today’s installed FC infrastructure

  13. EthernetFrame FCoEEncapsulation FCPacket FC-4 (FCP for SCSI) FC-4 (e.g. FCP or FICON) FC-3 (Common Services) FC-3 (Common Services) FC-2 (Framing, Flow-Control) FC-2 (Framing, Flow-Control) FC-1 (Encode/Decode) Enet MAC FC-0 (Phy) Enet Phy Fibre Channel over Ethernet Overview • FC over Ethernet • Layers FC frames directly over Ethernet. • Replacing lowest level of FC with Ethernet • Requires FC equivalent no-drop behavior • …But… Ethernet needs enhancements, to: • Provide no-drop behavior in face of congestion • Manage traffic interferences

  14. Enterprise Computing Community – ECC 2009 CEE Components • Priority-based Flow Control (PFC) • Improves on current 802.3x PAUSE mechanism by allowing link level flow control to be applied separately on 8 traffic classes. This is necessary (esp. on FC traffic) to eliminate packet drops due to congestion. • Enhanced Transmission Selection (ETS) • Supports bandwidth allocation to Priority Groups. Enables bandwidth sharing between Priority Groups carrying bursty high offered loads. It allows other traffic classes to use the available bandwidth when the offered load in a traffic class doesn’t use its allocated bandwidth. Additionally, it allows strict priority for time-sensitive and management traffic requiring minimum latency • Data Center Bridging Exchange (DCBX) Protocol • discovery/management framework for CEE-specific features and used to exchange CEE capabilities between peers. It leverages IEEE 802.1AB Link Level Discovery Protocol for these exchanges.

  15. Traffic Examples DCB and CEE • LAN • Storage • Clustering • Streaming • Management Ethernet Convergence • DCETM - Cisco marketing term (does not refer to industry standard) • Data Center Bridging (DCB) refers to a set of Ethernet enhancements currently being pursued in IEEE 802.1 • Per-priority Flow Control • Enhanced Transmission Selection • Discovery and Capability Exchange • Congestion Notification • Converged Enhanced Ethernet (CEE) is the name folks (EMC, HP, IBM and trade press) have given to the output DCB specifications for the following 3 functionswhich are viewed as required for FC convergence with Ethernet: • Per-priority Flow Control • Enhanced Transmission Selection • Discovery and Capability Exchange • These are currently being developed by the CEE Authors Group as a “version 0” of the standards to be used as input to IEEE 802.1 (http://tech.groups.yahoo.com/group/cee-authors/)

  16. Enterprise Computing Community – ECC 2009 What is Cloud Computing? A delivery method, a user experience, and a business model • Cloud computing is an emerging style of IT delivery in which applications, data, and IT resources are rapidly provisioned and provided as standardized offerings to users over the web in a flexible pricing model. An infrastructure management and services delivery methodology • Cloud computing is a way of managing large numbers of highly virtualized resources such that, from a management perspective, they resemble a single large resource. This can then be used to deliver services with elastic scaling.
