20120047330 | I/O EFFICIENCY OF PERSISTENT CACHES IN A STORAGE SYSTEM - A system and method are disclosed for improving the efficiency of a storage system. At least one application-oriented property is associated with data to be stored on a storage system. Based on the at least one application-oriented property, a manner of implementing at least one caching function in the storage system is determined. Data placement and data movement are controlled in the storage system to implement the at least one caching function. | 2012-02-23 |
20120047331 | SYSTEMS AND METHODS FOR MANAGING AN UPLOAD OF FILES IN A SHARED CACHE STORAGE SYSTEM - Systems and methods for managing a storage device are disclosed. Generally, in a host to which a storage device is operatively coupled, wherein the storage device includes a cache for storing one or more discardable files, a file is identified to be uploaded to an external location. A determination is made whether sufficient free space exists in the cache to pre-stage the file for upload to the external location and the file is stored in the cache upon determining that sufficient free space exists in the cache to pre-stage the file for upload to the external location, wherein pre-stating prepares a file for opportunistically uploading such file in accordance with an uploading policy. | 2012-02-23 |
20120047332 | Combining Write Buffer with Dynamically Adjustable Flush Metrics - In an embodiment, a combining write buffer is configured to maintain one or more flush metrics to determine when to transmit write operations from buffer entries. The combining write buffer may be configured to dynamically modify the flush metrics in response to activity in the write buffer, modifying the conditions under which write operations are transmitted from the write buffer to the next lower level of memory. For example, in one implementation, the flush metrics may include categorizing write buffer entries as “collapsed.” A collapsed write buffer entry, and the collapsed write operations therein, may include at least one write operation that has overwritten data that was written by a previous write operation in the buffer entry. In another implementation, the combining write buffer may maintain the threshold of buffer fullness as a flush metric and may adjust it over time based on the actual buffer fullness. | 2012-02-23 |
20120047333 | EXTENDING A CACHE COHERENCY SNOOP BROADCAST PROTOCOL WITH DIRECTORY INFORMATION - In one embodiment, a method includes receiving a read request from a first caching agent, determining whether a directory entry associated with the memory location indicates that the information is not present in a remote caching agent, and if so, transmitting the information from the memory location to the first caching agent before snoop processing with respect to the read request is completed. Other embodiments are described and claimed. | 2012-02-23 |
20120047334 | FLEXIBLE SELECTION COMMAND FOR NON-VOLATILE MEMORY - Some embodiments of the invention pertain to a memory system containing multiple memory devices, in which one or multiple ones of the memory devices may flexibly be selected at one time for a common operation to be performed by all the selected devices concurrently. | 2012-02-23 |
20120047335 | LOGIC VERIFYING APPARATUS, AND COMPUTER-READABLE RECORDING MEDIUM IN WHICH LOGIC VERIFYING PROGRAM IS STORED - A logic verifying apparatus includes a second processor corresponding to a first processor to be verified; and one or more second controllers corresponding to first controllers to be verified, the number of which is less than that of the first controllers, control a second access to a memory, the access being made by the second processor, the second processor and the second controllers serving as elements in the verification model. The second processor includes a storing unit that stores information that assigns one or more of the second controllers that is to be used as the verification model; and a converting unit that converts a first address into a second address, the first address indicating an entity that the second processor is to access through the one second controller assigned by the information stored in the storing unit such that the second processor access to the memory. | 2012-02-23 |
20120047336 | METHOD OF VERIFYING SYSTEM PERFORMANCE AND PERFORMANCE MEASUREMENT APPARATUS - A computer-readable, non-transitory medium storing a program for measuring a performance in a system including a storage unit and a plurality of control units for controlling an access to the storage unit, the program causing a computer to execute a procedure, the procedure includes estimating a specification area in address information including an address area in which an address of an access target of the storage unit is set and the specification area in which specification information for specifying a control unit for controlling an access to the access target is set, and verifying a reliability of the system by accessing the storage unit on the basis of a specification information in the specification area. | 2012-02-23 |
20120047337 | SYSTEMS AND METHODS FOR INITIALIZING A MEMORY SYSTEM - Systems and methods for initializing a memory system are provided. One system includes a processor and a memory including a storage volume coupled to the processor. The storage volume includes a first bitmap for tracking an initialization process for the storage volume and a second bitmap for tracking a copying process for the storage volume. A method includes performing, via the processor, an initialization process for the storage volume and tracking, via the processor utilizing the first bitmap, the initialization process. The method further includes performing, via the processor, a copying process for the storage volume prior to completing the initialization process and tracking, via the processor utilizing the second bitmap, the copying process. Also provided are computer storage mediums including computer program code for performing the above method. | 2012-02-23 |
20120047338 | SWITCHING VISIBILITY BETWEEN VIRTUAL DATA STORAGE ENTITIES - Various embodiments for switching visibility between virtual data storage entities in a data storage environment using a processor device are provided. Visibility of a data storage entity on a first storage system is switched to a replicated data storage entity on a second storage system. Data from the data storage entity is replicated from the first storage system to the second storage system using a common serial number. The data storage entity is hidden from the first storage system by concealing the common serial number. An ejection of the data storage entity from the first storage system is automated, and the replicated data storage entity is introduced to the second storage system. | 2012-02-23 |
