FIG. 1 representatively illustrates embeddedcomputer system 100 in accordance with an exemplary embodiment. As shown inFIG. 1 , embeddedcomputer system 100 may include an embeddedcomputer frame 102,backplane 104,shelf 109 with software and a plurality of slots for insertingcomputing blade 108,power distribution units 106, and the like.Backplane 104 may be used for coupling blades placed in plurality of slots and power distribution. - In an embodiment, a
computing blade 108 may comprise a switch blade, payload blade, and the like, coupled to any number of other computing blades viabackplane 104.Backplane 104 may accommodate any combination of a packet switched backplane including a distributed switched fabric or a multi-drop bus type backplane. Backplanes may support AdvancedTCA™, CompactPCI®, CompactTCA™, and the like.Computing blade 108 may add functionality to embeddedcomputer system 100 through the addition of processors, memory, storage devices, I/O elements, and the like. In other words, acomputing blade 108 may include any combination of processors, memory, storage devices, I/O elements, and the like, to give embeddedcomputer system 100 any functionality desired by a user. In the embodiment shown, there are sixteen slots to accommodate any combination ofpower distribution units 106 andcomputing blades 108. However, an embeddedcomputer frame 102 with any number ofshelves 109 or slots may be included in the scope of the disclosure. - In an embodiment, embedded
computer system 100 can use a switch blade as a central switching hub with any number of payload blades coupled to the switch blade. Embeddedcomputer system 100 may support a point-to-point, switched input/output (I/O) fabric. Embeddedcomputer system 100 may include both node-to-node (for example computer systems that support I/O node add-in slots) and chassis-to-chassis environments (for example interconnecting computers, external storage systems, external Local Area Network (LAN) and Wide Area Network (WAN) access devices in a data-center environment). Embeddedcomputer system 100 may be implemented by using one or more of a plurality of switched fabric network standards, for example and without limitation, InfiniBand™, Serial RapidIO™, Ethernet™, AdvancedTCA™, CompactPCI®, CompactTCA™, PCI Express™, and the like. Embeddedcomputer system 100 is not limited to the use of these switched fabric network standards and the use of any switched fabric network standard is within the scope of the disclosure. - In one embodiment,

distribution unit frame 210 may have afrontal length 213. The frontal length may be chosen by a systems designer, and may correspond to one of several industry standard frontal lengths. For example, afrontal length 213 of substantially 19″, 23″ and 600 mm are well known. Other frontal lengths are within the scope of the disclosure. In an embodiment, thefrontal length 213 may be smaller than that accepted by an embeddedcomputer frame 102. In this embodiment, powerdistribution unit frame 210 may include anadaptor module 215 on one or both ends.Adaptor module 215 may function to allow a powerdistribution unit frame 210 with a smaller frontal length to interface with an embeddedcomputer frame 102 designed to accept a power distribution unit frame with a larger frontal length. Although powerdistribution unit frame 210 is shown in a horizontal configuration, this is not limiting of the disclosure. Powerdistribution unit frame 210 may be in a vertical configuration, withfrontal length 213 being the height of powerdistribution unit frame 210, and be within the scope of the disclosure. -
FIG. 3 representatively illustrates apower distribution unit 306 in accordance with an exemplary embodiment. In the embodiment shown inFIG. 3 ,power distribution unit 306 has a2U form factor 312. -
Rear portion 320 of powerdistribution unit frame 310 may include a plurality ofpower ingress sites 330 where power may enterpower distribution unit 306. Each of plurality ofpower ingress sites 330 may include aningress pin 332 coupled to interface with an ingress, in-linehyperboloid radial socket 334. In an exemplary embodiment, eachpower ingress site 330 may include twoingress pins 332, a power input pin and a return pin. Eachingress pin 332 is coupled to interface with an ingress, in-linehyperboloid radial socket 334. - In an embodiment, ingress, in-line
hyperboloid radial socket 334 may be comprised of multiple contacting elements that are hyperbolically arrayed around the inner diameter of the socket. Each of the contact elements may be skewed with respect to the axial direction of the socket. When theingress pin 332 is coupled with the socket, the contacting elements mechanically wrap around the ingress pin providing a normal force for a positive mechanical and electrical connection. Coupling ingress, in-linehyperboloid radial socket 334 toingress pin 332 does not require mechanical fasteners. An example of an embodiment of an ingress, in-linehyperboloid radial socket 334 is the RADSOK® connector as described in the “RADSOK® High Amperage Electrical Terminals, Technical Brief” May 2001. - Ingress, in-line
hyperboloid radial socket 334 may be coupled toingress power conductor 336, whereiningress power conductor 336 is coupled to bring power topower distribution unit 306.Radial socket 334 has an in-line configuration such that the axial direction of both theradial socket 334 and theingress power conductor 336 are in substantially the same direction. This is as opposed to a non-in-line radial socket where the axial direction of theradial socket 334 and aningress power conductor 336 are offset substantially ninety degrees with respect to each other. - The in-line configuration of
radial socket 334 allows morepower ingress sites 330 in the limited space defined by a projection of therear portion 320 ofpower distribution unit 306. This also allows for a greater current capacity density of thepower distribution unit 306 and plurality ofpower ingress sites 330, which may be defined as the amount of current input through therear portion 320 of apower distribution unit 306. - In an embodiment, each of
power ingress sites 330 may have a current capacity of at least one hundred amperes. That is to say, eachpower ingress site 330 is capable of conducting at least one hundred amperes intopower distribution unit 306. In an embodiment,power distribution unit 306 may have at least sixpower ingress sites 330, giving thepower distribution unit 306 and plurality of power ingress sites 330 a current capacity density of at least six hundred amperes. -
Rear portion 320 of powerdistribution unit frame 310 may include a plurality of power egress sites 340 where power may exitpower distribution unit 306. Each of plurality of power egress sites 340 may include anegress pin 342 coupled to interface with an egress, in-linehyperboloid radial socket 344. In an exemplary embodiment, each power egress site 340 may include twoegress pins 342, a power output pin and a return pin. Eachegress pin 342 is coupled to interface with an egress, in-linehyperboloid radial socket 344. - In an embodiment, egress, in-line
hyperboloid radial socket 344 may be comprised of multiple contacting elements that are hyperbolically arrayed around the inner diameter of the socket. Each of the contact elements may be skewed with respect to the axial direction of the socket. When theegress pin 342 is coupled with the socket, the contacting elements mechanically wrap around the egress pin providing a normal force for a positive mechanical and electrical connection. Coupling egress, in-linehyperboloid radial socket 344 toegress pin 342 does not require mechanical fasteners. An example of an embodiment of an egress, in-linehyperboloid radial socket 344 is the RADSOK®connector as described in the “RADSOKO® High Amperage Electrical Terminals, Technical Brief” May 2001. - Egress, in-line
hyperboloid radial socket 344 may be coupled toegress power conductor 346, whereinegress power conductor 346 is coupled to distribute power frompower distribution unit 306 to any number of computing blades.Radial socket 344 has an in-line configuration such that the axial direction of both theradial socket 344 and theegress power conductor 346 are in substantially the same direction. This is as opposed to a non-in-line radial socket where the axial direction of theradial socket 344 and anegress power conductor 346 are offset substantially ninety degrees with respect to each other. - The in-line configuration of
radial socket 344 allows more power egress sites 340 in the limited space defined by a projection of therear portion 320 ofpower distribution unit 306. This also allows for a greater current capacity density of thepower distribution unit 306 and plurality of power egress sites 340, which may be defined as the amount of current output through therear portion 320 of apower distribution unit 306. - In an embodiment, at least a portion of the plurality of power egress sites 340 may have a current capacity of at least one hundred amperes. That is to say, at least a portion of the plurality of power egress site 340 is capable of conducting at least one hundred amperes out of
power distribution unit 306. In an embodiment,power distribution unit 306 may have at least ten power egress sites 340. In an embodiment, a power egress site 340 may supply power to a computing blade requiring at least two hundred Watts. - In the foregoing specification, the disclosure has been described with reference to specific exemplary embodiments; however, it will be appreciated that various modifications and changes may be made without departing from the scope of the present disclosure as set forth in the claims below. The specification and figures are to be regarded in an illustrative manner, rather than a restrictive one and all such modifications are intended to be included within the scope of the present disclosure. Accordingly, the scope of the disclosure should be determined by the claims appended hereto and their legal equivalents rather than by merely the examples described above.
