Abstract: In computing scenarios involving an aggregation of multiple computational units into a server or computer set, many architectures may be devised to provide physical storage and logical aggregation of the computational units. Presented herein are variations of one such architecture, comprising a chassis having a set of slots, into which may be inserted a tray storing the computational units of one or more blades. Respective trays and chassis slots comprise a power connector and a network connector that are positioned to connect directly (i.e., without a cable or manual interaction) when a tray is inserted into a slot. The chassis stores a set of power supplies, and may connect each blade with a power supply, optionally providing power routing and failover capabilities. The chassis may also provide a management component that connects to and provides management capabilities of the blades of the trays, power supplies, and climate regulating components.
