Abstract: The present disclosure describes embodiments of a computing system having a circuit for detecting a leak of a liquid in the cooling system and associated techniques and configurations. In some embodiments, the computing system includes a server board having a cooling system, and the circuit, wherein the circuit includes a first conducting element disposed on a substrate and coupled to a first voltage and a second conducting element disposed on the substrate and coupled to a second voltage. The first and second conducting elements are proximately disposed near each other, and the proximate positions are selected such that voltage across the conducting elements changes when a liquid is in simultaneous contact with the two conducting elements. In some embodiments, a detection circuit is coupled to the two electrodes to detect when the liquid is in simultaneous contact with the two conducting elements. Other embodiments may be disclosed and/or claimed.

Abstract: A system that may optionally be partitioned into multiple domains is disclosed. Each domain is capable of independently powering on, executing a firmware program, and loading an operating system, including a legacy operating system, as well as running an application program that is distinct from programs running on another domain. Interrupts, including boot interrupts, reset handlers, and inter-chassis communications are initialized differently, depending on whether the system is to be partitioned or not. The cost of redundant hardware and/or firmware is substantially avoided, yet the system fully supports multiple domains.
