Agenda

!   Using FCoE as a storage overlay !   Single-hop, multi-hop and beyond !   40GbE and 100GbE !   Real-world use cases !   OpenStack, Network Functions Virtualization (NFV) and

FCoE

Ethernet As We Know It

802.1Qbb – Priority Flow Control (PFC)

!   VLAN Tag enables 8 priorities for Ethernet traffic

!   PFC enables Flow Control on a

Per-Priority basis !   Provides the ability to have

lossless and lossy priorities at the same time on the same wire

!   Allows FCoE to operate over a lossless priority independent of other priorites

STOP PAUSE

802.1Qaz – Enhanced Transmission Service (ETS)

!   Allows you to create priority groups

!   Can guarantee bandwidth !   Can assign bandwidth

percentages to groups !   Not all priorities need to be used

or in groups.

History of Convergence – Using FCoE to Provide Consolidated I/O

!   Traditional Data Centers had separation at the host

!   Separate Ethernet-based networks and Fibre Channel-based networks

!   Multiple cards per server !   2 HBAs !   Average of 6 (or more!) NICs per server !   High underutilization drives up unnecessary

power, cooling, and asset costs

* not to scale

11

History of Convergence – Using FCoE to Provide Consolidated I/O

!   Access-Layer Convergence !   Consolidate I/O on 10G links !   Drastically reduced CapEx and OpEx !   Multiprotocol connectivity eased

purchasing decisions for server refreshes !   Prepared Data Centers for VM mobility

requirements !   Any VM could connect to FC storage if

necessary, not just the ones with HBAs pre-installed

* not to scale

12

History of Convergence – Using FCoE to Provide Consolidated I/O

!   Multi-hop Convergence !   Standardize on Ethernet assets

!   One physical infrastructure !   Keeps best practices for both Ethernet

and Fibre Channel

!   Reduction of Additional Equipment !   Protected investment and future-

proofed deployments

* not to scale

FCoE Overlay

13

Traditional SAN North South

!   Traditional storage topologies north-south

!   Physical air gap between fabrics

!   Requires large amounts of planning

14

Next Evolution of Convergence due to Hardware and Software Improvements

!   How to address new topologies? !   What about multiprotocol storage? !   Can we get true consolidated I/O throughout the fabric?

Evolution of Convergence

!   Use IEEE ETS to guarantee bandwidth for traffic types !   Use IEEE PFC to create lossless traffic for FCoE !   Use advanced Ethernet fabric forwarding for ECMP traffic flows !   Use Ethernet infrastructure for all kinds of storage (including connections to traditional FC storage

environments !   Increase IT agility and operational and resource efficiency while speeding delivery of services to application

owners !   Improve scalability for all application needs and maintain high, consistent performance for all traffic types,

not just storage 16

iSCSI/ NFS FCoE Fibre

Server

Logical Separation of SAN A/B

!   Storage sees an edge-core topology equivalence

!   Complete, load-balance ISLs dynamically created between FCF leafs

!   Logical separation instead of physical separation

!   Creates relationships between Fibre Channel Forwarders (FCFs)

!   Increases redundancy and resiliency

!   Storage traffic is load-balanced across Equal-Cost Multipathing Topology

!   If a spine switch fails, SAN A is not interrupted!

Boeing Aerospace and Defense – Case Study

!   Reduced deployment times for each server by 25% !   Saved 35% in Cap-ex and cut 90% of power costs

!   “…utilizing the cores better, and increasing I/O with fewer cables and switches” !   “…use our existing personnel to manage both IP and FCoE resources quickly and

efficiently, increasing their value within the company.”

Major Telco – Case Study

!   FCoE in Data Center consolidation project !   Migrated to 10G using multichannel

technology with DCB protocols !   Multiple virtual NIC interfaces and

FCoE on single 10G port for CAPEX and OPEX savings

!   Benefits !   Consolidated from multiple 1G

interfaces to redundant 10G interface while maintaining QoS per interface

20

OpenStack and FCoE

!   Open Source Cloud Computing Platform !   Enables Infrastructure as a Service (IaaS)

!   Cinder component provides block storage support !   Major Block Storage Platforms supported including EMC VMAX

& VNX, HDS, IBM Storwize, HP 3PAR StorServ

Network Functions Virtualization

!   Initiative to transform traditional network appliances into virtualized network function !   Examples include load

balancers, firewalls, intrusion detection

!   Enables migration from appliances to standard hardware and cloud based infrastructure

!   Is not Software Defined Networking

“Direct Connect” FCoE FC-BB-6 VN2VN Support

!   ANSI Standard enabling direct FCoE Virtual Node to Virtual Node (VN2VN) connectivity !   Specified in Fibre Channel

Backbone 6 (FC-BB-6) standard !   Similar to Fibre Channel Arbitrated

Loop !   Still requires DCB support for

lossless Ethernet link or fabric

!   Configurations !   Can be server and storage back to

back or using a DCB capable switch

!   Can be multiple servers connected to storage, or a server connected to multiple targets
