Method and system for managing execution of virtual applications

Номер: US20120005246A1

Автор: Kenji C. Obata

Принадлежит: Code Systems Corp

A system and method for directing download and execution of an application. A runtime engine receives an identifier of a block of shared memory from a directing process. The shared memory stores a map indicating which portions of an application file have been stored in a local copy of the application file. The runtime engine also receives an instruction from the directing process to execute the local copy when the local copy stores less than the entire application file. As the application executes, the runtime engine identifies requests from the application to access portions of the local copy and uses the map to determine whether the requested portions have been stored in the local copy. If the requested portions are not stored in the local copy, the runtime engine prevents the executing application from accessing the local copy until the map indicates the requested portions have been stored therein.

Increasing data access performance

Номер: US20120054427A1

Принадлежит: Cisco Technology Inc

Techniques are described for increasing data access performance for a memory device. In various embodiments, a scheduler/controller is configured to manage data as it read to or written from a memory. Read access is increased by partitioning a memory into a group of sub-blocks, associating a parity block with the sub-blocks, and accessing the sub-blocks to read data as needed. Write speeds may be improved by adding a pending write buffer to a group of memory sub-blocks. Such a buffer may be sized to be equal to the group of memory sub-blocks. The pending write buffer is used to handle collisions for write accesses to the same block, allowing two simultaneous writes to any regular memory block to occur.

Techniques are described for managing access of executing programs to non-local block data storage. In some situations, a block data storage service uses multiple server storage systems to reliably store network-accessible block data storage volumes that may be used by programs executing on other physical computing systems. 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 physical computing systems at that data center. If a program using a volume becomes unavailable, another program (e.g., another copy of the same program) may in some situations obtain access to and continue to use the same volume, such as in an automatic manner in some such situations.

Read messages are grouped by a plurality of unique sequence identifications (IDs), where each of the sequence IDs corresponds to a specific read sequence, consisting of all read and read-ahead requests related to a specific storage segment that is being read sequentially by a thread of execution in a client application. The storage system uses the sequence id value in order to identify and filter read-ahead messages that are obsolete when received by the storage system, as the client application has already moved to read a different storage segment. Basically, a message is discarded when its sequence id value is less recent than the most recent value already seen by the storage system. The sequence IDs are used by the storage system to determine corresponding read-ahead data to be loaded into a read-ahead cache.

In the technique, the receiver, rather than the sender, maintains a fingerprint dictionary for previously uploaded data. When a sender has additional data to be uploaded, the sender extracts fingerprints for units of the data and sends the fingerprints to the receiver. The receiver checks its fingerprint dictionary to determine the data units to be uploaded and notifies the sender of the identified units, which then sends the identified units of data to the receiver. The technique may, for example, be applied in virtualized data store systems to reduce bandwidth usage in uploading data.

Systems configured for improved storage system communication for n-way interconnectivity

Номер: US20120185643A1

Принадлежит: LSI Corp

Storage systems configured for improved N-way connectivity among all of a plurality of storage controllers and all of a plurality of storage devices in the system. All controllers of the storage system are coupled through a switched fabric communication medium to all of the storage devices of the storage system. Thus, the back-end interface of each storage controller of the storage system is used for all communications with any of the storage devices as well as for any communications among the controllers to coordinate the N-way distribution of stored data in a declustered RAID storage environment. This use of the back-end channel for all storage controller to storage device N-way connectivity as well as controller to controller N-way connectivity eliminates the need for a dedicated inter-controller interface for such N-way connectivity and eliminates the over-utilization of a front-end (e.g., network) communication path for providing N-way connectivity in the storage system.

Each bit of the third portion of the first block may indicate whether an attempt to write data to a corresponding one or more words of the first portion of the first block has failed since the last erase of the corresponding one or more words of the first portion of the first block. Whether data to be written to a particular virtual address is written to the first block or the second block may depend on the write status of the first block and the second block.

Making automated use of data volume copy service targets

Номер: US20120198190A1

Автор: Anil Kalavakolanu, Brian Hart

Принадлежит: International Business Machines Corp

A computer implemented method for automatically managing copies of source data volumes is provided. A copy management agent receives a message that target volume copies of source volumes are available. The copy management agent accesses the target volume copies of the source volumes. The copy management agent analyzes metadata for the target volume copies. The copy management agent determines whether any of the target volume copies is a boot volume copy based on the analyzed metadata. In response to a determination that one of the target volume copies is a boot volume copy, the copy management agent directs a provisioning agent to provision a new host for the target volume copies. The copy management agent directs the storage subsystem to present the target volume copies to a storage area network port associated with the new host. Then, the new host is booted using the boot volume copy.

An integrated circuit device includes a transmitter circuit operable to transmit a timing signal over a first wire to a DRAM. The DRAM receives a first signal having a balanced number of logical zero-to-one transitions and one-to-zero transitions and samples the first signal at a rising edge of the timing signal to produce a respective sampled value. The device further includes a receiver circuit to receive the respective sampled value from the DRAM over a plurality of wires separate from the first wire. In a first mode, the transmitter circuit repeatedly transmits incrementally offset versions of the timing signal to the DRAM until sampled values received from the DRAM change from a logical zero to a logical one or vice versa; and in a second mode, it transmits write data over the plurality of wires to the DRAM according to a write timing offset generated based on the sampled values.

Managing read requests from multiple requestors

Techniques are disclosed for managing data requests from multiple requestors. According to one implementation, when a new data request is received, a determination is made as to whether a companion relationship should be established between the new data request and an existing data request. Such a companion relationship may be appropriate under certain conditions. If a companion relationship is established between the new data request and an existing data request, then when data is returned for one request, it is used to satisfy the other request as well. This helps to reduce the number of data accesses that need to be made to a data storage, which in turn enables system efficiency to be improved.
