Patent number: 10855805Abstract: A centralized storage-connected switch port auto-configuration system includes an SDN controller device that receives, from an SDN switch device subsequent to a storage device being connected to a switch port on the SDN switch device, discovery information and uses it to identify the switch port. The SDN controller device then provides SDN communications to the SDN switch device that include a port packet data unit size configuration, a port traffic suppression configuration, and a port loop prevention configuration. The SDN switch device applies the port packet data unit size configuration to configure a packet data unit size transmittable via the switch port, the port traffic suppression configuration to configure the amount of bandwidth of the switch port that will be available to transmit at least one type of data traffic, and the port loop prevention configuration to configure loop prevention designations that will be available for the switch port.Type: GrantFiled: May 26, 2017Date of Patent: December 1, 2020Assignee: Dell Products L.P.Inventors: Ajan Daniel Kutty, Srinivasa Rao Nagalla

Patent number: 10574596Abstract: An FSB-enabled SDN system includes an FC storage device coupled to an FSB device by an FCF device. An SDN FSB device couples a server device to the FCF device, and is also coupled to an SDN controller device. The SDN FSB device prevents first FCoE data traffic while allowing FIP data traffic between the server device and the FCF device based on SDN communications from the SDN controller device. The SDN FSB device then forwards FC login communications included in the FIP data traffic to the SDN controller device. If the FSB device then receives a third SDN communication from the SDN controller device that includes an FC source identifier for the server device, it may allow second FCoE data traffic between the server device and the FC storage device if that second FCoE data traffic is associated with the FC source identifier.Type: GrantFiled: May 23, 2017Date of Patent: February 25, 2020Assignee: Dell Products L.P.Inventors: Ajan Daniel Kutty, Srinivasa Rao Nagalla

Publication number: 20180367319Abstract: A power over Ethernet (PoE) system includes a device and a power sourcing equipment (PSE) device that is configured to couple to the device through an Ethernet cable. The PSE device detects, in response to the device being coupled to the PSE device, that the device is a powered device. Subsequent to detecting that the device is a powered device, the PSE device determines whether a powered device identifier has been received from the device. In response to determining that a powered device identifier was received from the device, the PSE device determines that the powered device identifier identifies an authorized powered device. The PSE device then identifies a powered device classification of the powered device, and provides to the device via the Ethernet cable, first power according to the powered device classification.Type: ApplicationFiled: June 15, 2017Publication date: December 20, 2018Inventors: Rabah S.

Patent number: 9727110Abstract: A power distribution system includes a manager provided on a network controller and an agent provided on a line module. The manager is operable to receive a configuration for a port on the line module. A connection to the port is then detected by the agent and communicated to the manager. At least one of the manager and the agent determines that the connection is for a powered device that is operable to receive power and data through the port. The manager then classifies the powered device. If the manager determines that the classification of the powered device corresponds to the configuration of the port, the manager provides power to the powered device through the port according to an allocation for the powered device from a global power budget.Type: GrantFiled: February 25, 2013Date of Patent: August 8, 2017Assignee: Dell Products L.P.Inventors: Rabah S.
