A modular data storage tape library includes a modular frame having a form factor similar to other types of computing racks. The modular data storage tape library includes a hermetically sealed enclosure within the modular frame and a cooling portion within the modular frame. Data storage tapes, data storage drives and robotics for moving the data storage tapes are included within the hermetically sealed enclosure. A heat exchanger transfers heat from the hermetically sealed enclosure to the cooling portion outside of the sealed enclosure through a boundary of the hermetically sealed enclosure without introducing air from the data center into the hermetically sealed enclosure. Because air is neither introduced nor removed from the hermetically sealed enclosure, humidity fluctuations are minimal, if existent, and contaminants are prevented from entering the hermetically sealed enclosure, thus increasing the life spans of the data storage tapes included in the hermetically sealed enclosure.

Retention mechanisms for retaining compute components within server racks are described. In one example, a retention mechanism includes a latching component configured to move between a locked position and an unlocked position. The retention mechanism also includes a retaining component configured to position the latching component in the unlocked position. Movement of the retaining component releases the latching component thereby allowing the latching component to move into the locked position.

Rack component retention mechanisms

Latching components for retaining rack component cases within server racks are described. In one example, a latching component is installed at an interior surface of a rack component case. The latching component includes a protrusion. The latching component is biased in a locked position in which the protrusion is outside the rack component case. The latching component is moveable from the locked position to an unlocked in which the protrusion is removed from outside the rack component case using an unlatching component.

A method for migrating a power shelf between being supplied single-phase power and three-phase power includes coupling a second power adapter to an input of a power shelf of a rack while power is being supplied to the power shelf via a first power adapter coupled to another input of the power shelf. The first power adapter includes a multi-pin connector coupled to the input and three other connectors each coupled to respective single-phase power sources and the second power adapter includes a multi-pin connector configured to couple with the other input and another connector configured to couple with a three-phase power source.

A patch panel assembly mounts in a rack on a side of the rack other than the front side of the rack and other than the back side of the rack and fits within a volume of space not occupied by rack slots of the rack. In some embodiments the patch panel assembly includes brackets that articulate into out of the volume of space in the rack in which the patch panel assembly is mounted to allow access to patch cable connectors coupled in the brackets of the patch panel assembly.

An expansion card mounting assembly includes a mounting structure and a circuit board coupled to the mounting structure. Expansion cards are mounted on a top side and a bottom side of the circuit board and secured at opposite ends by a moveable plate of the expansion card mounting assembly. The mounting structure includes an opening along a length of the expansion cards that allows air to flow over the expansion cards in multiple directions including a vertical direction. The moveable plate and mounting structure are configured to allow a position of the moveable plate on the mounting structure to be adjusted to mount expansion cards having different lengths in the expansion card mounting assembly.
