Abstract: A method includes determining a cluster reliability of a computing cluster including a maximum computing capacity and representative of a reliability of the computing cluster when utilizing an entirety of the maximum computing capacity. The operations include receiving a provisioning request of the computing cluster including a threshold reliability of the computing cluster. In response to the provisioning request, determining, using the cluster reliability, a reserved computing capacity of the computing cluster based on the threshold reliability. The reserved computing capacity is less than the maximum computing capacity. Based on the reserved computing capacity and the maximum computing capacity, the operations include determining an unreserved computing capacity of the computing cluster. The operations include provisioning the computing cluster for execution of a user workload. The user workload executes on the unreserved computing capacity.

Abstract: A cargo rack is usable to store electronic devices, such as servers, while the electronic devices operate. The cargo rack has a telescoping enclosure with one or two doors for selectively closing either or both ends of the enclosure. The cargo rack also includes an onboard electronic system. The electronic system includes a programmable controller and an access control system for selectively locking or unlocking the door or doors of the enclosure. The access control system includes a security interface at which access credentials may be presented from outside the enclosure for recognition by electronics within the enclosure.
