NVMe SSD? Not yet, says Pure, but promises to deliver it Pure's NVMe-Ready Guarantee promises every newly purchased FlashArray//M can be upgraded to full NVMe through their Evergreen Storage program. NVM Express (NVMe) is a standard memory-class protocol for CPU-to-media communication, and came into being generally as a standard driver for PCIe-connected flash cards. The protocol …
Not really - there are two aspects here.
1.) SSDs and shelves - these can be swapped pretty easily and without interruption. Don't need to go into detail.
2.) Their heads work in an active/passive manner. Again, these swap out non-disruptively and you get free ones anyway with maintenance.
Job done - I don't think that's a fork lift, your understanding of a fork lift (or their architecture) is flawed.
Most storage vendors can perform controller swaps without bringing the system down. That's not really new.
Pure's argument is that there is no Forklift upgrade because there is no migration of data from one array to another. Swapping controllers is just like your grandfather's axe. You might never have bought a new axe, but you certainly don't have the old one either.
"Pure's argument is that there is no Forklift upgrade because there is no migration of data from one array to another."
That's not "an argument", that's just the definition of "no forklift upgrade".
"Swapping controllers is just like your grandfather's axe. You might never have bought a new axe, but you certainly don't have the old one either."
So what happened to the axe?

Lets put this FUD to rest... a Nimble controller CAN be a live upgrade.
We can also do firmware upgrades live in the middle of the day without needing support intervention/handholding/dictation on an enterprise, 6x9 primary storage system. All thanks to Infosight.
I'll just leave this here...

By the way - that's not to say either is a good idea. Maintenance windows should ALWAYS be taken.
Last time i checked, most of the storage vendors out there were calling larger SSD's innovation. The sooner people start talking about NVMe the better. It's just unfortunate that the companies who retrofitting disk systems for Flash know that talking NVMe and Flash futures burns their own architectures at the stake.
While it's always a dangerous move to talk about futures, the proof will play out in the coming year.
