ca Optimizing a cache back invalidation policy By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A method, a system and a computer program product for enhancing a cache back invalidation policy by utilizing least recently used (LRU) bits and presence bits in selecting cache-lines for eviction. A cache back invalidation (CBI) utility evicts cache-lines by using presence bits to avoid replacing a cache-line in a lower level cache that is also present in a higher level cache. Furthermore, the CBI utility selects the cache-line for eviction from an LRU group. The CBI utility ensures that dormant cache-lines in the higher level caches do not retain corresponding presence bits set in the lower level caches by unsetting the presence bits in the lower level cache when a line is replaced in the higher level cache. Additionally, when a processor core becomes idle, the CBI utility invalidates the corresponding higher level cache by unsetting the corresponding presence bits in the lower level cache. Full Article

The mechanism configures a write buffer memory with a plurality of write buffer portions. Each write buffer portion is dedicated to a predetermined block size category within a plurality of block size categories. For each write operation from an initiator, the mechanism determines a block size category of the write operation. The mechanism performs each write operation by writing to a write buffer portion within the plurality of write buffer portions corresponding to the block size category of the write operation.

ca System and method for determining a level of success of operations on an abstraction of multiple logical data storage containers By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT Various systems and methods are described for configuring a logical data storage container. In one embodiment, an instruction to perform an operation to modify an attribute of the logical data storage container that is an abstraction of a plurality of pertinent storage containers is received. A translated instruction to perform a sub-operation associated with the operation is transmitted to each of a number of the plurality of pertinent storage containers. A level of success of the performing of the operation on the logical data storage container is detected based on a comparison of a threshold value to a level of success of the performing of the sub-operation on each of the number of the plurality of pertinent storage containers. A report of the detected level of success is communicated. Full Article
ca Dynamically expandable and contractible fault-tolerant storage system with virtual hot spare By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A dynamically expandable and contractible fault-tolerant storage system employs a virtual hot spare that is created from unused storage capacity across a plurality of storage devices. This unused storage capacity is available if and when a storage device fails for storage of data recovered from the remaining storage device(s). On an ongoing basis, the storage system may determine the amount of unused storage capacity that would be required for the virtual hot spare (e.g., based on the number of storage devices, the capacities of the various storage devices, the amount of data stored, and the manner in which the data is stored) and generate a signal if additional storage capacity is needed for a virtual hot spare.
