Chris I agree with your assessment here on the reality of flash arrays. Customers are reporting the following outcomes: CAPEX savings with predictability in the performance tier of storage as they no longer need hundreds of spindles to reach the requisite performance. They also report CAPEX savings with snapshot copies on flash arrays eliminating the need for full physical copies for test and dev and on separate arrays. They also report OPEX savings with not only power and cooling but also with improved staff productivity (no more complex database-storage tuning required for example). Lastly because of the speed of flash they also report that they can now process significantly more data and analytic workloads are completing faster and they can do more in the same amount of time
According to IDC’s Marketscape WW AFA In 2015-2016 Vendor Assessment, AFAs are expected to generate $2.53 billion in revenue and grow at a compound annual growth rate (CAGR) of 21.6% to crest $5.5 billion in 2019. At that point, AFA revenue is expected to account for 60-70% of all external primary storage spend.
This data tells us that the adoption of flash technology in primary storage is in full swing and it’s become more affordable for general purpose workloads, not just those that demand the highest levels of performance.
