When I wrote this article for The Register in October 2010, there was a torrent of naysayers and witch hunters spewing their opinions in the comments section. I don’t have a problem with that, I was only expressing an opinion myself, after all. I don’t actually own a time machine and so any of my predictions are only based upon observations in the industry. It is heartening, though, to see that the prediction is coming true a little bit sooner than I expected with the announcement from EMC that VMAX will be relegated to the Capacity Tier. At least it seems that EMC ‘get it’, and are doing the right thing.
Like it or not, solid-state storage is the future of high-performance storage, and the hardware/software architectures have to change to keep up with the dramatic reduction in latency solid-state storage brings. Flash storage isn’t perfect, but the next technologies in solid-state storage remove many of its deficiencies and retain or improve on those latency numbers. There is no going back, only forwards.
