A latch comprises a frame securable to a device enclosure, and a handle slidably secured to the frame, wherein the handle can slide between an inward position and an outward position, and wherein the distal end of the handle has a drive pin. The latch further comprises a rigid pawl having a latch key, a distal end pivotally secured to the frame, and a slot that receives the drive pin. Inserting the handle causes the drive pin to move within the slot, push the pawl toward a side of a chassis bay, and deploy the latch key into engagement with a slot in the side of the chassis bay. Withdrawing the handle causes the drive pin to move within the slot, pull the pawl away from a side of the chassis bay, and withdraw the latch key out of engagement with the slot in the side of the chassis bay.

Latch for securing a compute node in a component storage rack

A latch selectively secures a compute node enclosure into a chassis bay. The latch comprises a frame securable to a proximal end of the compute node enclosure. A handle is pivotally secured to the frame intermediate a proximal end of the handle and a distal end of the handle so that the handle can be pivoted between a closed position and an open position. A proximal end of a pawl is pivotally coupled at to the distal end of the handle, wherein the pawl includes a landing at a distal end of the pawl and a latch key intermediate proximal and distal ends of the pawl. Movement of the handle positions the pawl into engagement with a slot in chassis bay to assist installation and removal of the compute node enclosure.

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

An embodiment of a computer rack is capable of supporting up to 48U of electronic devices, including a central rack space for up to 42U and six 1U side bays. The side bays are fully accessible from the rear of the rack, so that all of the components may be serviced without pulling the rack out from a row and removing side panels. Optional strip PDUs may be mounted at the rear. The rack complies with standard dimensions for a 19-inch rack, including standard vertical and horizontal rail dimensions, and fits on a standard 600 mm&#xd7;1200 mm floor tile.

High-capacity computer rack with rear-accessible side bays

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.

Reducing impact of repair actions following a switch failure in a switch fabric

A latch comprises a frame securable to an enclosure, and a handle pivotally secured to the frame for pivoting between a closed position and an open position. The distal end of the handle has a drive pin extending therefrom. The latch also comprises a pawl having a latch key, a distal end secured to the frame, and a proximal end coupled to the drive pin. Closing the handle causes the drive pin to move the pawl toward a side of the chassis bay and deploy the latch key into engagement with a slot in the side of the chassis bay. Opening the handle causes the drive pin to move the pawl away from a side of the chassis bay and withdraw the latch key out of engagement with the slot in the side of the chassis bay.

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.

Implementing ultra high availability personality card

A reduced insertion force mezzanine connector is used to couple first and second circuit boards. In one embodiment a connector frame has a first end disposed against the first circuit board and defining a first wall, and an opposing second end disposed against the second circuit board and defining a second wall generally parallel with the first wall. A plurality of wafers are disposed. Each wafer has a first edge in sliding contact with the first wall and an opposing second edge in sliding contact with the second wall. A plurality of electrically conducting pathways extend along each wafer from the first edge to the second edge. A wafer guide structure defines a plurality of wafer-support aisles on the first and second walls for receiving the edges of the wafers to constrain the wafers with a fixed spacing and generally parallel alignment. A plurality of terminals are biased to protrude laterally into each wafer support aisle, and are spaced along the wafer support aisle such that each wafer is movable within the respective wafer support aisle between a first position, wherein each electrically conducting pathway is disposed between adjacent terminals, to a second position, wherein each electrically conducting pathway is in electrical contact with a terminal on the first wall and an associated terminal on the second wall.

Method for establishing a high speed mezzanine connection

A latch apparatus and method to facilitate leveraged insertion of a component into a component bay to an interfaced position, securing of the component in the component bay when the component interfaces with a host computer, leveraged dislodgement of the component from its interfaced position for removal of the component from the component bay, and proper positioning of the latch apparatus upon insertion of the component housing to ensure proper engagement of the latch apparatus with the component bay for leveraged insertion and removal. One latch apparatus comprises a frame adapted to be secured to a proximal end of a component housing, a handle pivotally secured to the frame, and an extendable arm slidably secured to a distal end of the handle and biased toward an extended position, wherein the distal end of the extendable arm has a distally extending latch key for engaging a slot in the component bay.
