摘要： A clustered storage array consists of multiple nodes coupled to one or more storage systems. The nodes provide a LUN-device for access by a client. The LUN-device maps to a source logical unit corresponding to areas of storage on the one or more storage systems. A target logical unit corresponds to different areas of storage on the one or more storage systems. The source logical unit is migrated in parallel by the multiple nodes to the target logical unit. Data to be copied from the source logical unit to the target logical unit are grouped into data chunks. Two or more of the plurality of nodes concurrently attempt to acquire an exclusive lock for a set of data chunks. The node acquiring the exclusive lock migrates the set of data chunks from the source logical unit to the target logical unit, while the exclusive lock is used to prevent other nodes from migrating the set of data chunks.

摘要： Noninvasive method of identifying and quantifying constituents of arterial plaque, comprising subjecting arterial walls to proton NMR spectroscopy or magnetic resonance imaging and looking for sharp spectral lines indicative of the accumulation of lipids within the walls of human arterial blood vessels, and detecting early changes to arterial walls due to atherogenesis. Also this method can be used to obtain information regarding chemical composition of atheroma in situ comprising subjecting an aortic wall to NMR spectroscopy or magnetic resonance imaging and observing spectral peaks indicative of accumulation of lipids within the aortic wall. Magnetic resonance imaging may also be used for this noninvasive method of diagnosing and monitoring atherosclerosis.

摘要： A multi-level cache comprises a plurality of cache levels, each configured to cache I/O request data pertaining to I/O requests of a different respective type and/or granularity. The multi-level cache may comprise a file-level cache that is configured to cache I/O request data at a file-level of granularity. A file-level cache policy may comprise file selection criteria to distinguish cacheable files from non-cacheable files. The file-level cache may monitor I/O requests within a storage stage, and may service I/O requests from a cache device.

摘要： A multi-level cache comprises a plurality of cache levels, each configured to cache I/O request data pertaining to I/O requests of a different respective type and/or granularity. A cache device manager may allocate cache storage space to each of the cache levels. Each cache level maintains respective cache metadata that associates I/O request data with respective cache address. The cache levels monitor I/O requests within a storage stack, apply selection criteria to identify cacheable I/O requests, and service cacheable I/O requests using the cache storage device.
