Patent number: 10002087Abstract: A request is received via a message submission queue. The request is sent from a core associated with an external processor coupled by a communication interface. The message submission queue is associated with a memory access engine circuit configured to perform one or more memory access functions. The memory access engine circuit is used to dequeuer a next message from its corresponding message submission queue. The memory access engine circuit is used to perform a message function invoked by the message. The memory access engine circuit is used to receive a result of performing the message function. The memory access engine circuit is used to prepare and send to an external processing core that sent the message a response message determined based at least in part on the result.Type: GrantFiled: March 31, 2016Date of Patent: June 19, 2018Assignee: EMC IP Holding Company LLCInventors: Samir Rajadnya, Karthik Ramachandran, Michael Nishimoto, Richard H.

Patent number: 8904093Abstract: A cache server receives wear usage information associated with a storage device, and receives an object to be cached in the storage device. The cache server also determines whether to store the object in the storage device based on the wear usage information. The cache server provides the object to the storage device for storage when it is determined that the object is to be stored in the storage device, and prevents the object from being stored in the storage device when it is determined that the object is not to be stored in the storage device.Type: GrantFiled: June 15, 2012Date of Patent: December 2, 2014Assignee: Juniper Networks, Inc.Inventors: Michael Nishimoto, Jaspal Kohli

Patent number: 8745262Abstract: A method and apparatus stores media content in a variety of storage devices, with at least a portion of the storage devices having different performance characteristics. The system can deliver media to a large number of clients while maintaining a high level of viewing experience for each client by automatically adapting the bit rate of a media being delivered to a client using the client's last mile bit rate variation. The system provides clients with smooth viewing of video without buffering stops. The client does not need a custom video content player to communicate with the system.Type: GrantFiled: January 14, 2013Date of Patent: June 3, 2014Assignee: Juniper Networks, Inc.Inventors: Jaspal Kohli, Kumar Narayanan, Prabakar Sundarrajan, Junxiao He, Michael Nishimoto, Mohammed Zubair Visharam, Vikram Venkataraghavan

Patent number: 8612668Abstract: A method and apparatus optimizes storage on solid-state memory devices. The system aggregates object storage write requests. The system determines whether objects associated with the object storage requests that have been aggregated fit in a block of the solid-state memory device within a defined tolerance. Upon the aggregation of object storage write requests that fit in a block of the solid-state memory device, the system writes the objects associated with the aggregated object storage write requests to the solid-state memory device.Type: GrantFiled: March 18, 2010Date of Patent: December 17, 2013Assignee: Juniper Networks, Inc.Inventors: Michael Nishimoto, Jaspal Kohli, Kumar Narayanan
