20090052474 | SELECTIVE BUILD FABRIC (BF) AND RECONFIGURE FABRIC (RCF) FLOODING - In one embodiment, detecting an initialization of a synchronization phase of a network device in a fiber channel fabric, performing synchronization phase optimization of the network device to select a predetermined number of interfaces, and transmitting a synchronization request on the predetermined number of interfaces, are provided. | 02-26-2009 |
20090067430 | PARTIAL BUILD OF A FIBRE CHANNEL FABRIC - In one embodiment, a technique for performing partial build fabric operations when merging two or more Fibre Channel fabrics is provided. By maintaining a Principal Switch already assigned for one of two merging fabrics, a limited “partial build” may be performed for the other merging fabric. As a result, the time required for a Principal Switch selection phase may be greatly reduced. | 03-12-2009 |
20090219928 | RETURNING DOMAIN IDENTIFICATIONS WITHOUT RECONFIGURATION - In one embodiment, a technique for returning Domain IDs to a Fibre Channel fabric without a full build fabric (BF) phase is provided. A switch in the fabric may send a principal switch a message requesting the return of one or more Domain IDs assigned to that device. The principal switch may update the list of fabric Domain IDs to remove the Domain IDs identified in the message and send the updated list to devices in the fabric. | 09-03-2009 |
20110200330 | Increasing the Number of Domain identifiers for Use by a Switch in an Established Fibre Channel Switched Fabric - The number of domain identifiers is incrementally increased for use by a switch in an established fibre channel switched fabric. In other words, the number of domains assigned to a switch by the Principal Switch of the fibre channel switched fabric is increased without triggering the reconfiguration of the established fibre channel switched fabric. In one implementation, incrementally adding one or more additional domain identifiers includes requesting said one or more additional domain identifiers from a Principal Switch of the fibre channel switched fabric using a different World Wide Name (WWN) than used to acquire the original one or more domain identifiers used by the switch. | 08-18-2011 |
20110219183 | SUB-AREA FCID ALLOCATION SCHEME - Certain embodiments of the present disclosure generally relate to allocating a sub-area of Fibre Channel addresses (FCIDs) to a device. A range of addresses may be assigned to the device using a mask address, where the most significant bits represent a mask and the least significant bits represent a sub-range of FCIDs available to be assigned to the device. Therefore, routing information may be stored efficiently in a Ternary Content Addressable Memory (TCAM) by storing a single entry in the TCAM for each sub-area of FCIDs allocated to a device, instead of storing an entry for each FCID. The single entry may indicate the mask address and the width of the mask. | 09-08-2011 |
20110228670 | N_Port ID Virtualization node redundancy - In one embodiment, a method includes establishing a link between two N_Port Identifier Virtualization (NPIV) switches, the link having a high cost assigned thereto. The NPIV switches are in communication with a plurality of hosts through an N_Port Virtualization (NPV) device. The method further includes receiving at a first of the NPIV switches, an indication of a failure at a second of the NPIV switches, receiving data at the first NPIV switch, the data destined for one of the hosts associated with a domain of the second NPIV switch, and forwarding the data to the NPV device for delivery to the host, wherein a Fibre Channel Identifier (FCID) of the host is the same before and after the failure at the second NPIV switch. An apparatus is also disclosed. | 09-22-2011 |
20120082155 | RETURNING DOMAIN IDENTIFICATIONS WITHOUT RECONFIGURATION - In one embodiment, a technique for returning Domain IDs to a Fibre Channel fabric without a full build fabric (BF) phase is provided. A switch in the fabric may send a principal switch a message requesting the return of one or more Domain IDs assigned to that device. The principal switch may update the list of fabric Domain IDs to remove the Domain IDs identified in the message and send the updated list to devices in the fabric. | 04-05-2012 |
20130010638 | Merging a Stand-Alone Switch to a Fibre Channel Network - A Fibre 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. | 01-10-2013 |
20130208625 | Persistent Principal Switch for Fibre Channel Fabric - According to one aspect, a Fibre 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 Fibre 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. | 08-15-2013 |
20140050077 | HITLESS PRUNING PROTOCOL UPGRADE ON SINGLE SUPERVISOR NETWORK DEVICES - In Service Software Upgrade (ISSU) permits administrators to upgrade the control plane software of a network device without any disruption to the traffic passing through the data plane of the network device. However, because the control plane is unavailable, the network device is unable to transmit periodic messages to re-subscribe to specific VLANs. This may result in a service outage in end devices that rely on the network device to receive data assigned to those VLANs. To prevent the network device from being unsubscribed from the VLANs while the control plane is unavailable, the network device may transmit a control plane message before starting ISSU. Once a neighboring network device receives the message, the neighboring device delays unsubscribing the network device until the control plane is again available. Thus, the network device may perform ISSU without the possibility of data traffic not reaching end devices. | 02-20-2014 |
20140177431 | GRACEFUL FAILOVER OF A PRINCIPAL LINK IN A FIBER-CHANNEL FABRIC - In one embodiment, detecting a failure mode of a first communication link on a first port, selecting a second communication link on a second port associated with the first port, and transmitting a profile information associated with the second port are provided. | 06-26-2014 |
20150049767 | METHOD AND SYSTEM FOR PROVIDING DISTRIBUTED ALLOWED DOMAINS IN A DATA NETWORK - Method and system for providing distributed domains in a fiber channel fabric including determining a domain configuration of a resource, retrieving one or more current domain configuration parameters, determining a list of domains in a fiber channel fabric, and generating an updated domain list for the resource in the fabric is disclosed. | 02-19-2015 |

20090108684 | Rotary switching mechanism - A switching system includes two or more rotary switching mechanisms for selectively moving items. The switching system may be used for switching optical elements, such as filters, into and out of an optical path, for example selectively placing one of a group of available filters into the optical path. Each of the rotary switching mechanisms has a passive torque device, including a mechanical flexure and a magnetic latch, that provides most of the torque for moving an item between a retracted position and an extended position, and vice versa. The passive torque device has a pair of null positions or detents at the retracted and extended positions. A brushless DC motor is used to provide a force to get the passive torque device out of these null positions. Thereafter the passive torque device is able on its own to provide most of the torque for movement. | 04-30-2009 |
