Controlling electromagnetic ('EM') radiation in a data center having a number EM sections, including: receiving, by an EM controller, a specification of preferred EM radiation characteristics for the data center; and setting, by the EM controller, a state of each EM section in accordance with the specification, where the state of each EM section may be one of: an absorption state in which the EM section absorbs EM radiation or a reflection state in which the EM section reflects EM radiation.

Controlling electromagnetic radiation in a data center

Techniques are disclosed for managing a switch fabric. In one embodiment, a server system is provided that includes a midplane, one or more server cards, switch modules and a management controller. The midplane may include a fabric interconnect for a switch fabric. The one or more server cards and the switch modules may be operatively connected to the midplane. The switch modules may be configured to switch network traffic for the one or more server cards. The management controller may be configured to manage the switch modules via the fabric interconnect.

Switch fabric management

Techniques are disclosed for reducing impact of a repair action in a switch fabric. In one embodiment, a server system is provided that includes a first interposer card that operatively connects one or more server cards to a midplane. The first interposer card may include a switch module that switches network traffic for the one or more server cards. The first interposer card may be hot-swappable from the midplane, and the one or more server cards may be hot-swappable from the first interposer card.

Reducing impact of a repair action in a switch fabric

Techniques are disclosed for reducing impact of a switch failure in a switch fabric. In one embodiment, a server system is provided that includes a midplane, one or more server cards and one or more switch cards. The midplane may include a fabric interconnect for a switch fabric. The one or more server cards may be coupled with the midplane, where each server card is hot-swappable from the midplane. The one or more switch cards may also be coupled with the midplane, where each switch card is also hot-swappable from the midplane. Each switch card includes one or more switch modules, and each switch module is configured to switch network traffic for at least one server card.

Reducing impact of a switch failure in a switch fabric via switch cards

Techniques are disclosed for reducing impact of a switch failure and/or a repair action in a switch fabric. In one embodiment, a server system is provided that includes a first interposer card that operatively connects one or more server cards to a midplane. The first interposer card may include a switch module that switches network traffic for the one or more server cards. The first interposer card may be hot-swappable from the midplane, and the one or more server cards may be hot-swappable from the first interposer card. The server system may further include an interconnect between the first interposer card and a second interposer card.

A method and circuit for implementing an enhanced availability personality card for a chassis computer system, and a design structure on which the subject circuit resides are provided. The personality card includes a first erasable programmable read only memory (EPROM) and a second EPROM, each EPROM storing Vital Product Data (VPD) and a first temperature sensor and a second temperature sensor sensing temperature. A primary bidirectional bus and a redundant bidirectional bus are respectively connected between the first EPROM and the first temperature sensor and the second EPROM and the second temperature sensor, and a pair of chassis management modules. Each chassis management module includes a switch connected to both the primary bidirectional bus and the redundant bidirectional bus providing redundant paths, enabling continued function with failure of any critical personality card component.

Methods and systems for implementing such methods for providing server fault notifications, diagnostic and system management information may include, but are not limited to: receiving a network fault status request input; illuminating one or more server node fault indicators for one or more degraded server nodes having one or more faults; receiving a server node fault status request input for a degraded server node having one or more faults; and displaying one or more diagnostic service notifications for one or more faults of the degraded server node. The displaying of the diagnostic service notifications may allow for the completion of various service operations associated with the service notifications once the information specific to a fault is presented.

Server network diagnostic system

Methods, apparatus, and product are disclosed for expanding functionality of hard drive bays in a computing system that include: providing, by a connector in a hard drive bay, access to two or more data communication busses of different type; receiving, by the connector of the hard drive bay, a device mounted within the hard drive bay; and communicately coupling, by the connector of the hard drive bay, the device to one of the data communication busses.

Expanding functionality of one or more hard drive bays in a computing system

A system comprises a server chassis and first and second hard disk drive carriers, wherein each carrier supports a hard disk drive. A first hinge rotatably connects a distal end of the first hard disk drive carrier to a first side of the chassis, wherein the first hinge allows the carrier to rotate about a first hinge axis between an open position and a closed position. The first hard disk drive carrier rotates in a first plane between an open position extending beyond the front of the chassis and a closed position within the chassis. A second hinge rotatably connects a distal end of the second hard disk drive carrier to a second side of the chassis that opposite the first side of the chassis, wherein the hinge allows the carrier to rotate about a second hinge axis between an open position and a closed position. The second hard disk drive carrier rotates in a second plane between an open position extending beyond the front of the chassis and a closed position within the chassis, wherein the second plane is parallel to the first plane.
