| New ways of deploying Flash are reinforcing economic arguments that will see a growth in the market for 'Big Data Flash', argues Marcos Burnett, Sales Director for Northern Europe, SanDisk. According to IDC, over the next five years, more than 95% of all IT expenditure will go towards the "third platform" of computing infrastructure (cloud computing, big data, mobile computing and the Internet of Things). Older storage infrastructures are not suited to handle the scale of many of the processes required for the current and emerging world, such as evolving workloads, intense and high demand scalability and resource agility. This has been the principal driver for the changing expenditure. Traditional HDDs, for example, are better for capacity-intensive environments that not only require a low dollar-per-gigabyte cost for capacity but also need relatively few inputs/outputs per second or IOPS per gigabyte. However, using the same approach in today's data intensive world would not be economical at all and IDC has spoken at length about the potential of Flash to dominate spinning disk in the performance intensive storage environments.
MANIFOLD RETURNS Hitting all of them at once, as you can with Flash, brings manifold returns. Also, deploying Flash within storage arrays built significantly to take advantage of Flash based media will result in lower storage administration. Revolutionary internal architecture completely eliminates complex set-up and tuning steps, while inherently delivering maximum performance. Given that a single tier of Flash based media will be deployed there is no more management of storage tiers and the 'chasing of performance hotspots'. However, though Flash is the only storage solution that is able to adequately cope with the demands of the third platform, until recently it has not been available at a reasonable enough price point for many, as the dollar-per-gigabyte cost has been a large barrier to entry into the secondary market. Though the absolute cost of Flash storage has been coming down significantly over the last few years, making the relative cost per TB of storage more attractive than ever in a Flash vs. traditional array, the applications in the secondary market have been unable to justify the cost of Flash, as they are unable to take advantage of conventional Flash performance to fully leverage secondary economic benefits.
SECONDARY BENEFITS To compare a Flash-based configuration with a storage solution built entirely out of capacity-optimised HDDs, we would have to assume that we'd need 4 times the number of devices to meet IOPS requirements, a number that significantly raises not only the acquisition cost but also the TCO of the solution.
