Abstract: A method for accessing stored entities (SEs) that are stored in a storage unit of a storage system, the method may include determining in a cyclic manner, by each compute node (CN) of a group of compute nodes, CN SEs budgets to be used in a cycle, based on a shared storage space that stores performance requests of Ces of the group.

Abstract: A method includes segmenting a virtual volume into an active area configured to map to a first type of storage and a non-active area configured to map to a second type of storage through a storage virtualization engine. The second type of storage includes data associated with a host device and the first type of storage includes point-in-time images corresponding to the data associated with the host device. The first type of storage offers a higher performance than that of the second type of storage. The method also includes allocating a portion of space in the first type of storage to serve as a cache memory during a write operation and/or a read operation, and reducing a latency associated with the response to a write request and/or a read request through performing the corresponding write operation and/or the read operation through the first type of storage.

Abstract: A method, a system and/or and an apparatus to minimize data loss by de-allocating storage space with the help of an Application Programming Interface (API). In one embodiment, the method includes reclaiming data storage in a storage device slated as a reclamation target by redirecting write commands intended for the reclamation target to a point-in-time volume of the reclamation target; generating a list of portions of storage from the reclamation target such that each portion of storage has an API state of unused as per a system that uses the storage device; and includes converting a reclamation state associated with each of the portions of storage to a state of ‘unused’. In addition, the method involves synchronization of the point-in-time volume with the reclamation target to capture any changes that might be associated with the point-in-time volume.

Abstract: A method of treating Parkinson's Disease in patients exhibiting increasing resistance to the administration of L-dopa due to loss of aromatic L-amino acid decarboxylic activity in striatal neurons comprises transfection of the caudate and/or putamen regions with a viral vector encoding AADC. The vector preferably has a promoter system provided for the expression of the AADC nucleic acid, and is injected at a slow rate, at a level designed to restore AADC activity to tissues undergoing progressive loss of that activity. The AADC renewed activity permits conversion of L-dopa, in the brain, to dopamine.
