Oxide reimagines private cloud as... a 2,500-pound blade server?

Re: Betting Factors

We certainly hope we're successful. So far the folks that have deployed the platform have been thrilled with the experience and the system as a whole.

The rack fits inside the standard 24" (600mm) floor tile common for most enterprise class data centers and colos. We're not trying to squeeze this in a telco CO or something.

The power shelf and rectifiers are common off the shelf parts from Murata used by hyperscalers and the public cloud providers. We'll replace them if you have a support contract, or folks can go source their own.

The coolest connectors in the product are coming from Samtec, we did a whole podcast on it. Really interesting stuff:

The casters are just to roll it into place, I can roll a fully populated rack by myself but we use 2 people for safety. Once in place on the floor tile you drop the feet for stability. If people are bumping into stuff that much maybe install the seismic kit too?

The zero used in the name is more about hexadecimal: 0x1de like 0x denotes hex, so more like mid 1800's.

Fun side note, our PCI ID is 01de

Re: ...yet you cannot buy a DC bus-bar-based system from Dell, HP, or Supermicro

The DC bus-bar is not a DC power supply.

The DC bus-bar is a large copper bar that runs the length of the back of the rack and distributes DC to all the compute sleds and switches in the rack.

The rack is AC powered and utilizes a Murata power shelf with 6 rectifiers for AC to DC conversion.

Re: Liquid cooling?

The rack is fully air cooled.

There is no liquid cooling in the product at this time and none planned at the moment.

There is a trio of 80mm fans in each compute sled along with 4x80mm fans for each of the two network switches. There are fans in the rectifiers inside the Murata power shelf. Because we paid a great deal of attention to thermodynamics and leverage 80mm fans for the entire rack we're able to achieve far better compute density and lower power utilization than comparable configurations.
