These things are very hard to find concrete data about for outsider, which I am one of, but at least nVidia has published that they're building their new Falcon controller chips based on a custom RISC-V architecture. It's hard to tell how widespread it is since they are not buying chips from Renesas or MIPS and looking at the board wouldn't necessarily show you there's a RISC-V chip in there. All we need now is a high performance variant of lowRISC to combine it with its safety features, port seL4 and MirageOS to it. Then would get finally get back what we had with the old Burroughs machines and enjoy safety and performance without having to choose.

Anyway, they announced this publicly in 2016 so I assume it's already hidden in some nVidia hardware. I also read about a storage vendor (Seagate? or WD?) working on a transition to RISC-V, but I cannot find it right now.

The reasons cited sound like those we heard about Linux and Samba or Linux and Apache in the past.
