Hey! The current generation rack is compatible with the current generation compute sleds, switch, and power shelves. The next-generation compute sleds will be compatible as well. Possibly the next-generation switch but I would have to defer to my colleagues for that answer.

We'll ultimately ship a next-generation rack to take advantage of changing constraints (e.g., physical form factor, power requirements) and we'll provide a mechanism for upgrading to that generation of rack as well. Likely, in the form of multi-rack connectivity to move workloads or perhaps even financial incentives to purchase the latest and greatest.

I don't work on the hardware side at Oxide so I don't have further details to share. Great question!
