摘要:
A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a memory module system and DIMM connector is provided. A DIMM connector includes a plurality of DIMM sockets for receiving a corresponding plurality of DIMMs in a radially oriented, angularly spaced orientation. The DIMM sockets are connected in parallel at a memory module junction so that socket terminals of each DIMM socket are joined to the same relative terminal of all the other DIMM sockets along electronic pathways of substantially equal length. A memory controller selectively communicates with the DIMMs via the DIMM junction. By virtue of the improved topology, impedance within the DIMM connector may be better matched to minimize reflections and improve signal quality.

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×1200 mm floor tile.

A computer system includes a plurality of blade servers, a midplane, a supplemental midplane, and a peripheral device separate from the blade servers. The midplane includes a plurality of connectors connecting the midplane to the plurality of blade servers. The supplemental midplane is separate from the midplane and includes a body, a plurality of connectors, and a peripheral connector. The plurality of connectors are attached to the body and connect the supplemental midplane to the plurality of blade servers. The peripheral connector is attached to the body and connects the supplemental midplane to the peripheral device. The plurality of connectors of the supplemental midplane communicate with the peripheral connector of the supplemental midplane. The plurality of connectors of the supplemental midplane are configured to be removably connectable to the midplane.

A method and system for packaging a computer system is disclosed. The computer system is capable of including a plurality of blades, a first plurality of devices, and a second plurality of devices. The method and system include providing a chassis having a first cavity, a first plenum, a second plenum and a common plenum therein. The first cavity retains the blades in parallel. The chassis is configured such that air sufficient to cool the blades is drawn into the chassis and through the blades. The first plenum is configured such that a first portion of the air sufficient to cool the first plurality of devices is drawn from the blades into the first plenum, through the first plurality of devices and into the common plenum. The second plenum is configured in an analogous manner for the second plurality of devices. The common plenum is configured such that a remaining portion of the air from the blades is drawn into the common plenum, and such that the first and second portions of the air are received into the common plenum from the first and second plurality of devices, respectively.

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 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.

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.

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.
