3 Abstract Fibre Channel has been the ubiquitous connection of choice for connecting storage within the datacenter for over fifteen years. Entering the sixth generation Where is Fibre Channel Going? Why has Fibre Channel been so popular for so long? Where does Fibre Channel fit with: Virtualization Data Center Workloads Cloud Computing Flash Storage

4 Fibre Channel: Timeline Cloud Ready 2016+: 128GFC (4 striped parallel lanes of 32GFC) Virtualization NPIV 2012: 16Gb FC 2009: FCOE 2008: 8Gb FC 2015+: 32Gb FC Converged Networks Arbitrated Loop 2005: 4Gb FC 1988: Work begins on protocol 2001: 2Gb FC 1997: 1Gb FC SAN products emerge Fabric Services

5 Fibre Channel: Continuing (and Growing) Relevance Fibre Channel storage remains dominant Total external storage revenue $22B $25B Block storage $17B $18B FC SAN iscsi SAN FCoE SAN.06 (Gartner Group, Forecast: External Controller-Based Storage, Worldwide, All Countries, , 3Q14 Update - October 2014) FC in the datacenter: 19% of data center switches are Fibre Channel IDC - Market Analysis Perspective: Datacenter Networks, 2014 Flash appliances, Flash arrays and Hybrid array deployments are mostly Fibre Channel FC for the cloud OpenStack is the largest OpenSource project ever. Significant (and growing) OpenStack ecosystem engagement FCIA member companies contributing to FC Openstack developments FC Switch zone management Storage vendors developing Openstack provisioning APIs FC HBA drivers inbox in OpenStack distributions Fibre Channel 43% of 2018 Storage Market FC Switch 18.9% Infiniband Switch 0.9% L2-3 Switch 80.2%

6 Why Fibre Channel? Non-Stop High Performance Scalable and Simple Fibre Channel is the only purposebuilt, data center proven network infrastructure for storage that keeps running, no matter what Enables resilient IT infrastructure that optimizes availability and minimizes application disruptions Industry leading network reliability minimizes management resources and costs Fibre Chanel delivers 16Gb Fibre Channel and 40Gb FCoE performance ideal for high density virtualization, cloud infrastructure, and SSD storage Lossless and deterministic networking ensures predictable performance under high utilization FC dedicated networks are inherently low latency and secure Fibre Channel fabrics are simple, and elastic networks that easily scale up and down as needed Backward compatibility enables scalability with new technology while leveraging legacy infrastructure

FCoE ports otherwise follow Ethernet standards and compatibility guidelines. *Dates: Future dates estimated.
