Fault Tolerant Network Server Having Multiple Slideably-Mounted Processing Elements Sharing A Redundant Array Of Independent Disks Through Scsi Isolators
US Patent:
6618821, Sep 9, 2003
Filed:
Jan 12, 2000
Appl. No.:
09/481954

Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
G06F 1100
US Classification:
714 14, 714 7
Abstract:
A fault tolerant network server is described. This server has a pair of processing units, each processing unit has at least one CPU, system memory, an interface for a RAID system, at least one disk drive, a network interface, a cluster network interface, a power supply, and a case. The cases of both processing units are slideably mounted in a rack-mountable server case. The server also has a RAID system mounted in the server case and powered by two, redundant, power supplies and coupled to the processing units through isolators for blocking transactions when a processing unit has insufficient power or is being serviced.
Method And Apparatus For Detecting The Presence Of A Hot-Pluggable Component In A Computer System
US Patent:
6990544, Jan 24, 2006
Filed:
Dec 17, 1999
Appl. No.:
09/466025

Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
G06F 13/00
US Classification:
710302, 710301, 710303, 710304
Abstract:
A method and apparatus for detecting the presence of hot-pluggable components in a computer system. The method and apparatus includes an electromagnetic energy source located on a first side of a system board proximate an edge connector, the electromagnetic energy source for generating electromagnetic energy directed at least toward a second opposing side of the system board. The method and apparatus further includes an electromagnetic energy detector located on the second side of the system board, the electromagnetic energy detector for detecting a presence of electromagnetic energy when a hot-pluggable component is not mated to the edge connector and the electromagnetic energy is thereby unobstructed by the hot-pluggable component, the electromagnetic energy detector further for detecting an absence of electromagnetic energy when the hot-pluggable component is mated to the edge connector and the electromagnetic energy is thereby obstructed by the hot-pluggable component.
