Wow! This is riddled with inaccuracies
This is a huge load of stupid.
"Every byte of flash storage that you buy from a hybrid vendor is more expensive than the same amount in an all-flash array, he argued.".
Based on what evidence? Just dropped there like there was an IDC report with that as the title. So only companies that don't sell spinning rust can discount SSDs?
"Customers might want to use all-flash arrays as the primary system, and then send snapshots from that system to a hybrid one. In the real world, that’s not really possible, he says. It would take a lot of technical work to make it happen."
That's just weirdly wrong. Does that person quoted actually have experience with SAN arrays? You can do that in the NetApp array he dismisses earlier in the story quite easily. I know lot of clients who do. It's not a special feature. EMC can replicate from flash to spinning even if you have to use RecoverPoint. It took 10 seconds to Google how to replicate from XtremIO to Vmax or VNX.
Just terribly stupid writing.
