Publication number: 20190036880Abstract: An automated firewall-compliant customer support resolution provisioning system includes a customer support system coupled to a customer device. The customer support system receives a first secure request from the customer device that identifies an event in the customer device and, in response, sends a first secure response through a firewall subsystem to the customer device within a first timeout period enforced by the firewall subsystem. The customer support system then determines event resolution information for the event. Subsequent to the first timeout period and based on the first secure response, the customer device sends a second secure request to the customer support system requesting the event resolution and the customer support system sends the event resolution information through the firewall subsystem to the customer device within a second timeout period enforced by the firewall subsystem. The customer device then utilizes the event resolution information to address the event.Type: ApplicationFiled: July 26, 2017Publication date: January 31, 2019Inventors: Sundar Dasar, Divya Vijayvargiya, Sanjay Rao, Yogesh Prabhakar Kulkarni

Publication number: 20190034375Abstract: Serial Peripheral Interface (SPI) and a first remote access controller device located on the first motherboard and coupled to the first SPI. An off-motherboard SPI storage device is connected to the first SPI, and when the first remote access controller device determines that log entries have been generated, it automatically copies the log entries to the off-motherboard SPI storage device via the first SPI. A second motherboard includes a second SPI that couples to the off-motherboard SPI storage device when the second motherboard replaces the first motherboard in the chassis. A second remote access controller device located on the second motherboard and coupled to the second SPI will then retrieve the log entries that were automatically copied to the off-motherboard SPI storage device, and send the log entries through a network to a support device.Type: ApplicationFiled: July 26, 2017Publication date: January 31, 2019Inventors: Sundar Dasar, Divya Vijayvargiya, Sanjay Rao, Yogesh Prabhakar Kulkarni

Publication number: 20190026022Abstract: An information handling system includes storage drives, a first storage controller configured to map to a first subset of the storage drives, a second storage controller configured to map to a second subset of the storage drives different from the first subset, and a BMC. The BMC directs the storage controllers to detect storage traffic to the first and second subsets of storage drives, compares the storage traffic from the storage controllers, and remaps the first storage controller to map storage transactions on a third subset of the storage drives different from the first subset when the comparison indicates that the first storage traffic is greater than the second storage traffic.Type: ApplicationFiled: July 20, 2017Publication date: January 24, 2019Inventors: Chandrashekar Nelogal, Yogesh P. Kulkarni, Sanjeev Dambal, Sundar Dasar

Patent number: 10152432Abstract: A support information provisioning system a support device, an external device; and a customer device. The customer device includes an external connector and a remote access controller device that is coupled to the external connector. In situations where the customer device is experiencing at least one customer device issue that prevents the customer device from provisioning support information related to the operation of the customer device, the remote access controller device operates to detect that the external device has been connected to the external connector and, in response, automatically cause new support information about that customer device to be generated. When the external device is subsequently connected to the support device, it may then provide that new support information to the support device for analysis.Type: GrantFiled: July 26, 2017Date of Patent: December 11, 2018Assignee: Dell Products L.P.Inventors: Sundar Dasar, Divya Vijayvargiya, Sanjay Rao, Yogesh Prabhakar Kulkarni

Publication number: 20180331913Abstract: An information handling system (IHS) includes controller that performs a method of automating acquisition of link local Internet Protocol (IP) network address of servers. Controller acts as Group manager server (GMS) that maintains an inventory of a respective link local Internet Protocol (IP) network address and public key of each server that is addressable over a local area network (LAN). GMS receives an IP network address and credentials associated with a management console that are used to obtain a public key from the management console. GMS transmits to the management console a GMS IP network address and public key associated with the GMS. GMS encrypts the inventory with the public key of the management console to generate an encrypted inventory. GMS transmits the IP network address and the public key of the management console to each server. GMS forwards the encrypted inventory to the management console to enable secure communication.Type: ApplicationFiled: May 12, 2017Publication date: November 15, 2018Inventors: SUNDAR DASAR, RAKESH K.

Patent number: 9886580Abstract: A method and information handling system (IHS) that optimizes boot time. The method includes a basic input output system (BIOS) performing an authentication check of drivers during an initial boot process. The results of the authentication check are stored along with an unified extensible firmware interface (UEFI) image for each driver in an authentication results data structure (ARDS). In response to receipt of a subsequent request to enable a secure boot of the IHS, when the initial boot process was performed with the secure boot disabled, the ARDS is accessed to determine if any of the drivers failed the authentication check. When none of the drivers have failed the authentication check, the boot process is continued using the UEFI images of the drivers. When at least one of the drivers has failed its authentication check, a notification is output indicating a failure of the authentication check.Type: GrantFiled: December 23, 2014Date of Patent: February 6, 2018Assignee: Dell Products, L.P.Inventors: Sundar Dasar, Yogesh P.

Patent number: 9715423Abstract: A method and an information handling system (IHS) perform server boot failure recovery by disabling failed devices and/or failed functions within functional devices. According to one aspect, a processor-executed fault isolation module (FIM) initiates calls to detected devices during a binding phase. The FIM identifies devices corresponding to successfully completed calls as operational devices, and identifies devices corresponding to failed calls as failed devices. Following completion of the binding phase, the FIM initiates calls, via a pre-boot application, to individual protocol functions of each operational device identified during the binding phase. If a first protocol call to a first operational device is successfully completed, the FIM identifies a protocol function(s) corresponding to the first protocol call as an operational function(s).Type: GrantFiled: January 8, 2016Date of Patent: July 25, 2017Assignee: Dell Products, L.P.Inventors: Sundar Dasar, Yogesh Prabhakar Kulkarni, Mark W.

Publication number: 20170098084Abstract: A first firmware volume of a Unified Extensible Firmware Interface (UEFI) compliant information handling system is accessed. Authentication information is retrieved from the first firmware volume using a UEFI Secure Architecture Protocol. Based on the authentication information, it is determined if the first firmware volume is a first type of firmware volume. If the first firmware volume is the first type of firmware volume, the first firmware volume is authenticated using the first authentication information and an authentication procedure other than Secure Boot authentication. If the first firmware volume is a second type of firmware volume, the second type different than the first type, the first firmware volume is authenticated using the first authentication information and the Secure Boot authentication.Type: ApplicationFiled: December 19, 2016Publication date: April 6, 2017Inventors: Yogesh P.
