hey, this is Rami .. I lead hw team in Cloudflare.

Great observation! these chassis are designed for 19" racks, not OCP spec. But, who does not love green thumb screws!

Can I ask the chassis and motherboard combination? I know previous generations have been based on QCT chassis and motherboard components. I am curious what the non-hotswap, shallow depth, 1S is as it probably saves a fair amount of money dropping the HPC/density and hot swap premiums.

We're still using ODM built servers that are available for the public. Yes, moving off the shared infra chassis helps us improve reliability & cost thru simplicity, and enables us to scale our infrastructure using single nodes vs. X nodes as the smallest scaling unit. Our machines are stateless as our globally interconnected infra is widely distributed and replicated. Hence we moved to no-hotplug.

Looks like an OCP mezzanine interface tho.

If a server can take OCP mezz cards and the BMC can be managed in the same manner and with the same tools as a fully OCP-spec system, does it really matter that it's not in an OCP-spec chassis and rack?

Yes, the chassis form factor does not matter much to us at this point.

Yes, we're using OCP Nic ... and many other components that are used by other servers/clouds. Nothing proprietary except our SW stack.
