Patent number: 8255922Abstract: A mechanism is disclosed for enabling multiple processes to share the same portion of physical memory. The first time an instance of a process is executed, a list of common components is compiled. The compiled code is then written into a newly created mappable data structure, which is stored into persistent storage. The next time an instance of that process is executed, the mappable data structure is mapped into a portion of the process instance's virtual memory space. This enables the process instance to invoke the compiled code for the common components. Multiple instances of the process may have their virtual memory spaces mapped to the same mappable data structure in this way. Thereafter, it is up to the operating system to load the contents of the mappable data structure into a portion of physical memory, and to ensure that all of the process instances share that physical memory portion.Type: GrantFiled: January 9, 2006Date of Patent: August 28, 2012Assignee: Oracle America, Inc.Inventors: Nedim Fresko, Jiangli Zhou, Dean R.

Patent number: 8219576Abstract: Multiple Network Attached Storage (NAS) appliances are pooled together by a virtual NAS translator, forming one common name space visible to clients. Clients send messages to the virtual NAS translator with a file name and a virtual handle of the parent directory that are concatenated to a full file-path name and compressed by a cryptographic hash function to generate a hashed-name key. The hashed-name key is matched to a storage key in a table. The full file-path name is not stored, reducing the table size. A unique entry number is returned to the client as the virtual file handle that is also stored in another table with one or more native file handles, allowing virtual handles to be translated to native handles that the NAS appliance servers use to retrieve files. File movement among NAS servers alters native file handles but not virtual handles, hiding NAS details from clients.Type: GrantFiled: July 9, 2010Date of Patent: July 10, 2012Assignee: Sanwork Data Mgmt L.L.C.Inventor: Juergen Brendel

Patent number: 8180842Abstract: A communication device management program that enables efficient use of memory space in receiving data using remote direct memory access (RDMA) techniques. The receiving node transmits a virtual ID corresponding to a receiving process to a remote sending node. A sending process in the sending node specifies this virtual ID when starting data transmission. If the receiving node has not reserved a memory area corresponding to that virtual ID, the sending node transmits a reservation request to the receiving node, which causes a data receiving memory area to be reserved for use by a communication device in the receiving node. In the sending node, the sending communication device begins sending transmission data in RDMA mode, from a memory area managed by the sending process to the reserved data receiving memory area. The receiving communication device directs incoming transmission data to a memory area managed by the receiving process.Type: GrantFiled: December 16, 2004Date of Patent: May 15, 2012Assignee: Fujitsu LimitedInventor: Koichi Hirai

Patent number: 8180843Abstract: A NAS switch provides file migrations in a NAS storage network that are transparent to the clients. A source file server exports an original NAS file handles indicative of object locations on the source file server to the NAS switch. The NAS switch modifies the original NAS file handles to an internal file system and maps the original NAS file handles to a switch file handles independent of location. The NAS switch exports the switch file handles to a client. The client looks-up objects and makes NAS requests to the source file server using switch file handles. The NAS switch performs file migration by first replicating the namespace containing data to be migrated from source file server to a destination file server. Separately, the NAS replicates data which is a relatively longer process than the namespace replication. During data replication, namespace access requests for objects are directed to the replicated namespace.Type: GrantFiled: January 24, 2008Date of Patent: May 15, 2012Assignee: Neopath Networks, Inc.Inventors: Thomas K.

Patent number: 8176142Abstract: Techniques are disclosed for sharing programmatic modules among isolated virtual machines. A master JVM process loads data from a programmatic module, storing certain elements of that data into its private memory region, and storing other elements of that data into a “read-only” area of a shareable memory region. The master JVM process copies loaded data from its private memory region into a “read/write” area of the shareable memory region. Instead of re-loading the data from the programmatic module, other JVM processes map to the read-only area and also copy the loaded data from the read/write area into their own private memory regions. The private memory areas of all of the JVM processes begin at the same virtual memory address, so references between read-only data and copied data are preserved correctly. As a result, multiple JVM processes start up faster, and memory is conserved by avoiding the redundant storage of shareable data.Type: GrantFiled: December 21, 2010Date of Patent: May 8, 2012Assignee: Oracle America, Inc.Inventors: Erez Landau, Dean R.

An input/output supervisor (IOS) record in a couple dataset is checked to retrieve PGIDs in the cluster. The metadata record, control unit list, and IOS record are compared, and if a PGID is found in the metadata record that is not in the IOS record and if the found PGID is not in the control unit list, the found PGID is not active on the shared device. The found PGID of the different cluster is removed from metadata record, and members of the cluster can R/W to file system.Type: GrantFiled: December 16, 2009Date of Patent: April 17, 2012Assignee: International Business Machines CorporationInventor: Harry M.

Patent number: 8135855Abstract: The subject matter herein relates to a method to “accelerate” the delivery of a portion of a data stream across nodes of a stream transport network. A portion of a live stream is forwarded from a first node to a second node in a transport network at a high bitrate as compared to the stream's encoded bitrate, and thereafter, the stream continues to be forwarded from the first node to the second node at or near the encoded bitrate. The disclosed technique of forwarding a portion of a stream at a high bitrate as compared to the encoded bitrate of the stream is sometimes referred to as “prebursting” the stream. This technique provides significant advantages in that it reduces stream startup time, reduces unrecoverable stream packet loss, and reduces stream rebuffers as the stream is viewed by a requesting end user that has been mapped to a media server in a distributed computer network such as a content delivery network.Type: GrantFiled: January 17, 2011Date of Patent: March 13, 2012Assignee: Akamai Technologies, Inc.Inventor: Ramesh K.

Patent number: 8117276Abstract: Some embodiments provide different frameworks for seamlessly issuing and executing commands across servers of different federation participants. Each framework facilitates issuance and execution of a command that originates from a first federation participant and that is intended for execution at servers of a second federation participant. In some embodiments, a framework implements a method for enabling command interoperability between distributed platforms that each operate a set of servers on behalf of content providers. The method involves receiving a command targeting a particular configuration that a first distributed platform deploys to a server that is operated by a second distributed platform. The method identifies the server of the second distributed platform that is deployed with the particular configuration.Type: GrantFiled: September 27, 2011Date of Patent: February 14, 2012Assignee: Edgecast Networks, Inc.Inventors: Jayson G.

Patent number: 8117274Abstract: Protocol is provided for safe transfer of files from between nodes of a communication system. The protocol includes a handshake operation between a source (local or initiating) node sending one or more files and a remote (responding) node receiving the files to ensure that control of the file remains with the source node until the file is successfully transferred. The protocol is provided by a file transfer manager that controls the transfer process through a series of file moves that include moving the file into a directory associated with the file transfer manager, from which the file is sent and moving the file out of that directory after the remote node acknowledges a safe copy operation of the file. Files are maintained in the sending directory and under control of the source node at least for a configurable amount of time until the file is safely transferred.Type: GrantFiled: April 11, 2002Date of Patent: February 14, 2012Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventor: Koen Schilders
