Patent number: 9813283Abstract: Methods and apparatus are provided for transferring data between servers and a remote entity having multiple peripherals. Multiple servers are connected to a remote entity over an Remote Direct Memory Access capable network. The remote entity includes peripherals such as network interface cards (NICs) and host bus adapters (HBAs). Server descriptor rings and descriptors are provided to allow efficient and effective communication between the servers and the remote entity.Type: GrantFiled: August 9, 2005Date of Patent: November 7, 2017Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Ariel Cohen, Abhinav Anand, Pierre Aulagnier, Gerald Cheung, Naveed Cochinwala, Greg Lockwood, Ganesh Sundaresan, Susheel Tadikonda, Vikram Venkataraghavan, Ming Wong

Patent number: 9264384Abstract: Methods and apparatus are provided for virtualizing resources such as host bus adapters connected to a storage area network. Resources are offloaded from individual servers onto a resource virtualization switch. Servers are connected to the resource virtualization switch using an I/O bus connection. Servers are assigned resources such as virtual host bus adapters and share access to physical host bus adapters included in the resource virtualization switch. Redundancy can be provided using multipathing mechanisms.Type: GrantFiled: March 16, 2005Date of Patent: February 16, 2016Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Ganesh Sundaresan, Raymond Lim, Shreyas Shah

Patent number: 8848727Abstract: A Small Computer System Interface (SCSI) transport for fabric backplane enterprise servers provides for local and remote communication of storage system information between storage sub-system elements of an ES system and other elements of an ES system via a storage interface. The transport includes encapsulation of information for communication via a reliable transport implemented in part across a cellifying switch fabric. The transport may optionally include communication via Ethernet frames over any of a local network or the Internet. Remote Direct Memory Access (RDMA) and Direct Data Placement (DDP) protocols are used to communicate the information (commands, responses, and data) between SCSI initiator and target end-points. A Fiber Channel Module (FCM) may be operated as a SCSI target providing a storage interface to any of a Processor Memory Module (PMM), a System Control Module (SCM), and an OffLoad Module (OLM) operated as a SCSI initiator.Type: GrantFiled: December 11, 2009Date of Patent: September 30, 2014Assignee: Oracle International CorporationInventors: Nakul Pratap Saraiya, Ganesh Sundaresan, William E.

Patent number: 8428463Abstract: Consistent with the present disclosure, a method and apparatus for providing a uniform spectral gain of an optical amplifier is provided. Namely, a “balancing” step is carried out in which an optical channel having the lowest power level input to an optical circuit, such as an dynamic gain equalizer (DGE), is assigned a zero “attenuation error” and is substantially un-attenuated by the DGE. The lowest power level optical signal does not require further attenuation and effectively serves as a reference power level, which the power levels of the remaining optical signals are set to. For example, remaining optical signals are assigned either positive or negative attenuation errors relative to the zero attenuation error based on optical signal input powers to the DGE and accumulated DGE attenuations over time. Those optical signals having a negative attenuation error are substantially unattenuated by the DGE, because such optical signals are adequately attenuated and do not require further attenuation.Type: GrantFiled: May 10, 2010Date of Patent: April 23, 2013Assignee: Infinera CorporationInventors: Benjamin A. Warren, Saurabh Kumar, Abhijeet D. Deore, Brian B. Shia, Ganesh Sundaresan

Patent number: 7602774Abstract: Methods and apparatus are provided for allowing quality of service (QoS) configuration for storage applications running on servers connected to a storage area network (SAN). Resources such as host bus adapters (HBAs) are offloaded from individual servers onto a resource virtualization switch. Servers are connected to the resource virtualization switch using an I/O bus connection. The resource virtualization switch provides storage applications running on connected servers with different quality of service levels. The resource virtualization switch can also apply traffic shaping policies associated with QoS.Type: GrantFiled: July 11, 2005Date of Patent: October 13, 2009Assignee: Xsigo SystemsInventors: Ganesh Sundaresan, Raymond Lim, Shreyas Shah, Ariel Cohen, Ming Wong
