Abstract: A flexible architecture for installing electronic equipment in a data center rack is provided, in the form of a virtual chassis. The virtual chassis simultaneously accepts multiple types of equipment items (e.g., computing devices, storage devices, communication devices) and/or multiple versions of a given type of equipment item, by altering the physical configuration of the chassis. As a result, cells or spaces of multiple different form-factors may be defined for receiving the equipment. Also, services such as data and power may be pre-attached to a virtual chassis so that when a computer server or other item is installed, it is automatically connected to the services without separate effort. One or more electronic equipment items, when installed in a cell of the chassis, may mate automatically with multiple data connectors and/or power connectors.

Abstract: Panels are extended from housings affixed to equipment racks that abut a cold aisle, during normal operation of the electronic equipment installed in the racks, in order to fully or partially contain the cold aisle (e.g., within a data center). The panels may extend automatically (e.g., during powering up of the equipment) and/or in response to a specific control. In response to an emergent condition (e.g., fire), and/or activation or deactivation of a control, the panels automatically retract. The retraction allows a fire suppression agent (e.g., water, foam) to enter the aisle, may allow easier access to the equipment, and/or provide other benefits. The panels are generally transparent in order to allow light to enter the aisle even when the panels are extended. In its extended orientation, a given panel may engage or be in contact with an opposing panel (e.g., across the cold aisle) and/or an adjacent panel.
