Publication number: 20090077208Abstract: Information handling system network addresses are managed to support a consistent MAC address for iSCSI and fibre channel host bus adapter. For example, a management controller retrieves a MAC address from persistent memory, such as a network location, and assigns the MAC address to a non-persistent memory of a predetermined information handling system network component so that the MAC address remains consistent even if the network component is replaced. For example, an offload engine that supports network communications with iSCSI receives a MAC address from a network location and applies the MAC address for use by a host bus adapter. Alternatively, an offload engine supports Fibre Channel with World Wide Name or World Wide Identifier address assignments.Type: ApplicationFiled: December 2, 2008Publication date: March 19, 2009Inventors: Cuong Nguyen, Michael A. Brundridge, Bruce Holmes, Michael Roberts

Publication number: 20080198749Abstract: A technique for handling a service request in an information handling system includes receiving, at a data link layer device, a packet transmitted from a client, the data link layer device including multiple ports. The packet is examined to determine whether the packet includes a first-type request. The packet is then routed to a server via a trusted port, included within the multiple ports, when the packet includes the first-type request.Type: ApplicationFiled: February 20, 2007Publication date: August 21, 2008Applicant: DELL PRODUCTS, LPInventors: Cuong T. Nguyen, Joseph D. DeNiro, Joseph Farrell, Bruce Holmes, Mohana Rao Mullapudi

Publication number: 20080101351Abstract: Information handling system network addresses are managed based on the location of the information handling system. For example, a blade information handling system chassis has network addresses stored in persistent memory and associated with each of plural slots. A blade information handling system inserted in a slot receives network addresses associated with the slot from a chassis management controller. A baseboard management controller of the blade information handling system receives the network addresses and applies the network addresses to power up networking components to communicate over a network with the network addresses, such as MAC addresses or WWN addresses.Type: ApplicationFiled: October 30, 2006Publication date: May 1, 2008Inventors: Cuong Nguyen, Michael A.

Publication number: 20070274239Abstract: A method for automatically detecting a port configuration mismatch between a switch and its peer switch comprises listening, by the switch, to its peer switch's advertisement of its duplex setting, generating a warning notification in response to the peer switch advertising as capable of only operating at half duplex and the switch being set to an auto-negotiate setting, and transmitting the warning notification to a user.Type: ApplicationFiled: May 26, 2006Publication date: November 29, 2007Applicant: Dell Products L.P.Inventors: Cuong T.

Publication number: 20070220618Abstract: Network communication cables that provide power, such as Ethernet cables in compliance with the Power over Ethernet standard, are secured so that unauthorized devices are restricted from receiving power. After a PoE connection is established between a powered device (PD) and power source equipment (PSE) over an Ethernet cable, the PD communicates security information to the PSE with low frequency variations in the current drawn by the PD through the Ethernet cable. The PSE terminates power to the PD if the PD fails to communicate the security information in a predetermined time period or if the security information fails to match authorized security information. Alternatively, the PSE generates an unauthorized device message for presentation at the network if the security information fails to match the authorized security information.Type: ApplicationFiled: March 20, 2006Publication date: September 20, 2007Inventors: Bruce Holmes, Joseph DeNiro, Joseph Farrell, Robert Luis, Mohana Mullapudi, Cuong Nguyen, Liam Quinn, Robert Winter

Publication number: 20070165539Abstract: A system and method is disclosed for configuring a network device. The system and method involves a network device that includes an external button for toggling the device between a managed mode and an unmanaged mode. When the device is toggled to a managed mode, an Internet Protocol (IP) address is temporarily assigned to the device and the device may be remotely configured. After configuration, the device can be returned to an unmanaged state, and the IP address assigned to the device is cleared. During the period that the device is in a managed state, an external indicator on the device is turned on to confirm that the device is in a managed state.Type: ApplicationFiled: January 13, 2006Publication date: July 19, 2007Inventors: Bruce Holmes, Joseph DeNiro, Joseph Farrell, Travis Hart, Mohana Mullapudi

Publication number: 20060235824Abstract: A method and system for improving the efficiency of a database processing system for evaluating candidate data items representing search listings that are submitted for inclusion into a search engine database. Candidate search listings are automatically assessed for quality, style, and relevance to evaluate risk of unfavorable reception by a user and of potential exposure volume. Search listings which are higher-risk or higher-volume are routed through manual editorial review while lower-risk, lower-volume search listings are routed for immediate inclusion in the search database without manual editorial evaluation. Accordingly, human editorial efforts can be devoted to manual review of high-risk or high-volume search listings while efficiency is simultaneously improved in the processing system as a whole.Type: ApplicationFiled: October 11, 2005Publication date: October 19, 2006Inventors: Dominic Cheung, Dennis Wu, Barry Laffoon, Alan Lang, Scott Snell, Jie Zhang, Pierre Wang, Jennifer Wu, Peter Goodwine, Wai-Yin Wong, Carey Sublette, Stephan Cunningham, Bruce Holmes
