| 20080201444 | FILE SHARING SYSTEM AND FILE SHARING METHOD - A system includes a client device to which mount information representing a server device associated with the client is set; a first server corresponding to the mount information set to the client device; a second server communicably connected to the first server; a first disk device controlled by the first server; and a second disk device controlled by the second server. When the client device sends a request to register a data file to the first server, the first server stores the data file in the first disk device and sends a command to make a tag file including information on a location of the data file to the second server. When receiving the command to make the tag file from the first server, the second server makes the tag file and stores it in the second disk device. | 08-21-2008 |

The system includes a data writer which writes data into the shared memory in one of the servers and then generates write state information on the write state of data written in the shared memory; and a data communicator which reads out the written data and positional information about a position on the shared memory of the written data on the basis of the write state information, and transfers the read data and positional information from the one server to another or some other servers. | 03-26-2009 |
| 20090307329 | ADAPTIVE FILE PLACEMENT IN A DISTRIBUTED FILE SYSTEM - In a distributed system that includes multiple machines, a scheduler attempts to schedule a task on a machine that is not currently overloaded with work. If a task is scheduled on a machine that does not yet have copies of the portions of the data set on which the task needs to operate, then that machine obtains copies of those portions from other machines that already have them. Whenever a “source” machine ships a copy of a portion to another “destination” machine in the distributed system, the destination machine persistently stores that copy on the destination machine's persistent storage mechanism. The copy also remains on the source machine. Thus, portions of the data set are automatically replicated whenever those portions are shipped between machines of the distributed system. Each machine in the distributed system has access to “global” information that indicates which machines have which portions of the data set. | 12-10-2009 |

A group of multiple server block data storage systems that store block data volumes may in some situations be co-located at a data center, and programs that use volumes stored there may execute on other computing systems at that data center, while the archival storage systems may be located outside the data center. The data stored on the archival storage systems may be used in various ways, including to reduce the amount of data stored in at least some volume copies. | 02-11-2010 |

| 20100268789 | NETWORK CACHING FOR MULTIPLE CONTEMPORANEOUS REQUESTS - A live caching system is described herein that reduces the burden on origin servers for serving live content. In response to receiving a first request that results in a cache miss, the system forwards the first request to the next tier while “holding” other requests for the same content. If the system receives a second request while the first request is pending, the system will recognize that a similar request is outstanding and hold the second request by not forwarding the request to the origin server. After the response to the first request arrives from the next tier, the system shares the response with other held requests. Thus, the live caching system allows a content provider to prepare for very large events by adding more cache hardware and building out a cache server network rather than by increasing the capacity of the origin server. | 10-21-2010 |
| 20100325235 | INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING SYSTEM CONTROL METHOD, CAPABLE OF PROVIDING, REGARDLESS OF EXECUTION/NON-EXECUTION OF AN APPLICATION, DATA USABLE BY THE APPLICATION TO OTHER INFORMATION PROCESSING APPARATUS - A CPU executes a communication partner search process for searching for a communication partner (another game machine). The CPU confirms received data content. If identification information included in the received data matches, application identification information saved in a wireless communication module is compared with application identification information included in the received data. When the pieces of application identification information match, a notice that another game machine having exchange data corresponding to the matched application identification information is found is given to a main body. Then, giving/receiving of exchange data is executed to/from another game machine. | 12-23-2010 |
| 20110145358 | SHARED JAVA JAR FILES - 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. | 06-16-2011 |

| 20120066337 | TIERED STORAGE INTERFACE - The cloud storage services are extended with a cloud storage service access protocol that enables users to specify a desired storage tier for each data stream. In response to receiving storage tier specifiers via the protocol, the cloud storage service performs storage operations to identify target storage devices having attributes matching those associated with the requested storage tier. The cloud storage service stores a data stream from the storage client in the identified target storage device associated with the desired storage tier. Storage tiers can be defined based on criteria including capacity costs; access latency; availability; activation state; bandwidth and/or transfer rates; and data replication. The cloud storage service protocol allows data streams to be transferred between storage tiers, storage devices to be activated or deactivated, and data streams to be prefetched and cached. The cloud storage services may charge storage clients based on storage tier use and associated operations. | 03-15-2012 |

| 20150381727 | STORAGE FUNCTIONALITY RULE IMPLEMENTATION - One or more techniques and/or systems are provided for storage functionality rule implementation on behalf of external client agents. For example, a network storage controller may be configured to perform storage operations on behalf of clients, such as providing read/write access to storage devices. The network storage controller may receive a storage functionality rule (e.g., a rule that tracing is to be enabled for write operations by user (B)) from an external client agent hosted on a client device. Responsive to identify a storage operation context that corresponds to the storage functionality rule (e.g., user (B) may attempt to perform a write operation), the network storage controller may implement the storage functionality rule for the storage operation context on behalf of the external client agent. In this way, network bandwidth and/or processing latency otherwise associated with obtaining storage operation processing instructions from the external client agent may be mitigated. | 12-31-2015 |
