Abstract

Fibre Channel has been the ubiquitous connection of choice for connecting storage within the datacenter for over fifteen years. The start of the sixth generation is being celebrated this year by introducing a staggering leap in performance and new features. We will discuss why fibre channel holds the enduring popularity it has as well as an in-depth look at the new Gen 6 features and what the future holds. We will discuss how fibre channel fits in with key datacenter initiatives such as Virtualization, the pervasive adoption of SSD

Fibre Channel: Continuing (and Growing) Relevance

Fibre Channel storage remains dominant 2012 2018 Total external storage revenue $22B $25B

Block storage $17B $18B – FC SAN 10.2 10.8 – iSCSI SAN 2.7 4.0 – FCoE SAN .06

(Gartner Group, Forecast: External Controller-Based Storage, Worldwide, All Countries, 2014-2018, 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

L2 - 3 Switch 80.2%

FC Switch 18.9% Infiniband

Switch 0.9%

Fibre Channel 43% of 2018

Storage Market


• 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

Non-Stop Scalable and Simple

• 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

High Performance

Why Fibre Channel?

• Fibre Channel is the only purpose-built, 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

• “FC” used throughout all applications for Fibre Channel infrastructure and devices, including edge and ISL interconnects. Each speed maintains backward compatibility at least two previous generations (I.e., 8GFC backward compatible to 4GFC and 2GFC)

FCoE

Fibre Channel over Ethernet tunnels FC through Ethernet. 10GFCoE was not available until after FC-BB-5, the FCoE protocol standard, was completed in 2007. For compatibility, all 10GFCoE FCFs and CNAs are expected to use SFP+ devices, allowing the use of all standard and non-standard optical technologies and additionally allowing the use of direct connect cables using the SFP+ electrical interface. FCoE ports otherwise follow Ethernet standards and compatibility guidelines. *Dates: Future dates estimated

FC Generational Cycles

Historical Assumptions New generation introduced every 3-4 years

Each generation spans up to 10 years Three generations overlap at any point in time

New generations are less defined by protocol speed, more by service level

16GFC & Gen6 Adoption *16GFC reaching 15% point now, 50% expected late 2016

**Gen 6 adoption may be accelerated with 16G optics

Generation Intro / GA Up to 10% shipments

What will drive the need for Gen 6

Performance Unleash application

performance with SSD storage
