The Why, When and How of Storage Convergence Zeus Kerravala March 2012 © Copyright 2010. Yankee Group Research, Inc. All rights reserved. Storage Convergence Page 1 The Era of Virtual Computing is Here Each era of computing: • Raised the strategic value of the network • Lowers the cost of computing • Increases the level of integration between network and computing © Copyright 2010. Yankee Group Research, Inc. All rights reserved. Storage Convergence Page 2 Drivers of Virtual Computing • Server virtualization and beyond • Resource efficiency • Cloud computing • Computing and network convergence © Copyright 2010. Yankee Group Research, Inc. All rights reserved. Storage Convergence Page 3 The Data Center is the Backbone of the Enterprise Consumerization, mobility and virtualization has transformed the way we work Information needs to be available on any device no matter where a worker is Local information that has to be moved between user devices, backed up and continually synchronized does not scale today Delivering information from the data center has become the most cost effective, scalable method. Data center transformation needs to be among the most crucial IT initiatives today Application optimization is best done in the data center © Copyright 2010. Yankee Group Research, Inc. All rights reserved. Storage Convergence Page 4 Limitations of Current Data Center Network Three tier architecture has too much latency to support real time and large workloads Spanning Tree Protocol (STP) leads to inefficient network infrastructure usage Traditional technology is not designed for virtual or cloud environments Poor management tools and high up front cost drive up TCO © Copyright 2010.

Storage Convergence Page 5 Defining a Network Fabric Flat network Every port virtually connected to every other Active / active switching High speed network; 10 GigE, roadmap to 40 Gig-E and 100 Gig-E Operationally simple Optimized for virtual traffic and east west traffic flows Optimized packet processing © Copyright 2010. Yankee Group Research, Inc. All rights reserved. Storage Convergence Page 6 Why Storage Convergence Will Occur • Current architecture is inefficient • Infrastructure consolidation and green IT will be easier to attain • IT better aligns with the vision of virtual IT • Creates fluid, efficient IT © Copyright 2010. Yankee Group Research, Inc. All rights reserved. Storage Convergence Page 7 Why Convergence Will Not Happen Overnight • • • • • • • • Storage is mission critical IT silos and separation of responsibility Unclear ROI Lack of a de facto standard Slow adoption of high speed Ethernet Complexity of convergence Lack of IT skills Requires forklift upgrade © Copyright 2010. Yankee Group Research, Inc. All rights reserved. Storage Convergence Page 8 Converged Storage Decision Criteria • Choice of migration path • Support for iSCSI and FCoE • High density 10 Gig-E, upgradeable to 40 and 100 © Copyright 2010. Yankee Group Research, Inc. All rights reserved. • • • Fabric architecture Designed for the virtual data center era Optimized for east-west and north-south traffic Storage Convergence Page 9 Steps to Storage Convergence 1. 2. 3. 4. 5. Consolidate Data Centers Migrate to a network fabric Move to advanced use of virtualization Implement lossless Ethernet Migrate to a converged environment over time © Copyright 2010. Yankee Group Research, Inc. All rights reserved. Storage Convergence Page 10 Conclusion Virtualization has transformed every part of IT – its now time for the network to evolve • Migration to a virtualized network and converged data center are necessary components of the virtual data center • Journey to a converged network is not trivial – stick to a structured, multi step process • Evaluate at least three solution providers • Start with a small deployment and grow at a manageable pace • Roll up data center operations to a single owner • © Copyright 2010.
