Integrated rack architecture for distributing two phase coolant

A data center system, comprising:

• an array of electronic racks, wherein each electronic racks comprises:
• a condensing region comprising:
• a condensing container housing condensing coils, and
• a coolant container situated at a height lower than the condensing container to contain two phase coolant;
• a coolant distribution region, comprising:
• a set of rack manifolds having at least a rack liquid supply line to receive a two phase coolant from the coolant distribution region, and
• a vapor line to return a vapor to the coolant distribution region;
• and
• a server region coupled to the condensing region and the coolant distribution region, the server region comprising a plurality of server slots to receive a plurality of servers, wherein each of the servers is at least partially submerged within two phase liquid coolant, wherein, when the servers operate, the servers generate heat that is transferred to the two phase liquid coolant thereby causing at least some of the two phase liquid coolant to turn into a vapor,
• wherein the server, coolant distribution, and condensing regions are integrated within the electronic rack.
