    How Broad All-Flash Vendor Portfolios Help IT Customers

    White Paper How Broad All-Flash Vendor Portfolios Help IT Customers Sponsored by: Dell EMC Eric Burgener May 2017 IDC OPINION In the current 3rd Platform computing era, enterprises of all sizes are being asked to continue to support legacy applications while providing support for next-generation applications (NGAs) in mobile computing, social media, big data/analytics, and cloud environments. At the same time, most information technology (IT) organizations are consolidating around virtual infrastructure for both legacy and new applications. This has significantly changed the I/O profiles that storage infrastructure has to deal with, and it has become clear that for most primary storage workloads, and even now for some secondary workloads, hard disk drives (HDDs) no longer adequately meet requirements. As a result, we are seeing overall enterprise storage revenue shift away from HDD-based designs toward newer flash-based designs with the following results: . Flash is rapidly coming to dominate primary workloads as a persistent storage medium. For latency-sensitive workloads, flash offers performance, capacity, storage density, energy and floor space consumption, efficiency, and reliability benefits that are compellingly better than the benefits systems based around HDDs can offer for 3rd Platform computing workloads, and 76% of enterprises plan to deploy or evaluate all-flash array (AFA) platforms in the next 12 months. Differing workload requirements are driving the rise of new storage architectures. In the past, most enterprise storage designs were based around a scale-up, dual-controller model, but in the past several years, new architectures have emerged, which include scale-out, software- defined, converged and hyperconverged infrastructure, and cloud designs.
