Patent number: 9385969Abstract: A Fiber (Fiber) Channel (FC) switch and related methods are provided for merging FC fabrics. During a merger process of two separate FC fabrics, a principal switch in a merged FC fabric allocates a domain identifier (ID) to each switch in the merged FC fabric. The principal switch is configured to build a complete domain ID list that identifies the domain IDs for all switches in the merged FC fabric. After the complete domain ID list is generated, the principal switch transmits a message to all switches in the merged FC fabric, the message including the complete domain ID list.Type: GrantFiled: September 3, 2013Date of Patent: July 5, 2016Assignee: Cisco Technology, Inc.Inventors: Kishan Kumar Kotari Uppunda, Prabesh Babu Nanjundaiah

Publication number: 20160072734Abstract: Presented herein are techniques for collecting and delivering consolidated nameserver information in a merged Fibre (Fiber) Channel (FC) fabric. A principal switch in a merged FC fabric collects information from one or more subordinate switches. The principal switch consolidates the information collected from the subordinate switches to generate consolidated nameserver information. The principal switch then pushes the consolidated nameserver information from the principal switch to each of the subordinate switches.Type: ApplicationFiled: September 10, 2014Publication date: March 10, 2016Inventors: Kishan Kumar Kotari U, Prabesh Babu NANJUNDAIAH, Chandrashekar Chikkalingaiah Manchanapuara, Vijayalakshmi Matada Chidanandaiah

Patent number: 9062725Abstract: A disc brake assembly includes a brake pad having a first pad abutment spaced from a second pad abutment and a third pad abutment positioned between the first pad abutment and the second pad abutment. An actuator is operable to apply a force to the brake pad to apply the brake. The disc brake assembly has a first reaction abutment facing the first pad abutment, a second reaction abutment facing the second pad abutment, and a third reaction abutment facing the third pad abutment. The first, second and third pad abutments are operable to transfer brake pad drag torque to the first, second and third reaction abutments respectively. The disc brake is configured such that under no load conditions with the third pad abutment engaging the third reaction abutment, the first pad abutment is spaced from the first reaction abutment.Type: GrantFiled: September 22, 2011Date of Patent: June 23, 2015Assignee: Meritor Heavy Vehicle Braking Systems (UK) LimitedInventors: Jason Morris, Paul Roberts, Norman Breakwell, Peter K.

Publication number: 20150103644Abstract: In one example embodiment, a time unconstrained fabric switch software upgrade function is described for an in-switch-software-upgrade/downgrade (ISSU) in a network switch. Prior to an ISSU, Hello protocol data unit (PDU) information is stored for relevant control protocols of associated interfaces of the switch. The Hello PDU information comprises information on messages and data exchanged by the control protocols that may be used to maintain communications links of the switch. During the configuring of the ISSU, and while the control plane of the switch is, at least partially, dysfunctional, Hello PDUs are sent on the interfaces according to the stored PDU information in order to maintain the communication links. The Hello PDU information may include a time interval value for each relevant protocol that determines when Hello PDUs are sent.Type: ApplicationFiled: October 11, 2013Publication date: April 16, 2015Applicant: CISCO TECHNOLOGY, INC.Inventors: Harsha Bharadwaj, Prabesh Babu Nanjundaiah, Sumanth Sindiri, Ankan Ghosh, Kishan Kumar Kotari Uppunda

Patent number: 8936138Abstract: A disc brake includes a brake disc, a sliding caliper, a single piston, and a brake pad carrier comprising a leading part and a trailing part. The brake pad carrier includes mounting features for securing the brake pad carrier to an associated structure of a vehicle. The mounting features define a mounting side and a non-mounting side of the brake. A mounting side brake pad comprises mounting side friction material and a non-mounting side brake pad comprising non-mounting side friction material. The center of pressure of the non-mounting side friction material is circumferentially aligned with the piston and the center of pressure of the mounting side friction material is offset in relation to the piston towards the leading part of the brake pad carrier.Type: GrantFiled: May 26, 2011Date of Patent: January 20, 2015Assignee: Meritor Heavy Vehicle Braking Systems (UK) LimitedInventors: Jason Morris, Paul Roberts, Norman Breakwell, Peter K.

Patent number: 8830871Abstract: According to one aspect, a Fiber Channel (FC) switch that is currently serving as a Principal Switch among a plurality of FC switches in a FC Fabric sends an Exchange Fabric Parameters (EFP) frame having an empty domain identifier list to neighboring FC switches during a first portion a Principal Switch Selection phase. During a second portion of the Principal Switch Selection phase that is after the first portion, the first Fiber Channel switch sends to neighboring FC switches an EFP frame having a non-empty domain identifier list to indicate to the neighboring FC switches that the first FC switch is to remain serving as the Principal Switch in the FC Fabric.Type: GrantFiled: February 15, 2012Date of Patent: September 9, 2014Assignee: Cisco Technology, Inc.Inventors: Christian Sasso, Siddharth Kasat, Ankur Goyal, Amitkumar Patel, Kishan Kumar Kotari Uppunda

Patent number: 8811227Abstract: A Fiber Channel (FC) switch and related methods are provided for merging the FC switch with an existing FC network. During a merge process of a stand-alone switch with an FC network, a first Exchange Fabric Parameters (EFP) frame is sent from the stand-alone switch to an FC switch in the existing FC network. The first EFP frame has an empty domain identifier (ID) list. The stand-alone switch receives a second EFP frame from the FC switch. The second EFP frame contains a domain ID list of domain IDs already in use in the FC network. The stand-alone switch compares the domain ID list in the second EFP frame with a stored list of one or more domain IDs associated with the stand-alone switch to determine if there is a domain ID overlap or conflict. If no conflict is detected, the stand-alone switch merges with the existing network without initiating a Build Fabric phase or a Principal Switch Selection phase that could cause disruption of traffic in the network.Type: GrantFiled: July 6, 2011Date of Patent: August 19, 2014Assignee: Cisco Technology, Inc.Inventors: Christian Sasso, Siddharth Kasat, Ankur Goyal, Amitkumar Patel, Kishan Kumar Kotari Uppanda
