Abstract: A method, computer system, and a computer program product for block prediction are provided. A computer receives a first retrieval request for retrieving data from storage blocks. The computer performs a cosine similarity comparison of the first retrieval request compared to prior data retrievals. The computer selects a matching data retrieval of the prior data retrievals. The matching data retrieval has a closest match to the first retrieval request based on the cosine similarity comparison. The computer identifies another storage block from the matching data retrieval as a predicted block for the first retrieval request. The computer transmits a prefetch request to prefetch data from the predicted block.

Abstract: Methods that can accelerate replication of file metadata on different sites are disclosed herein. One method includes recreating, by a processor, a transaction history for a predetermined period of time for a set of consumer sites of a first storage network and synchronizing data in the set of consumer sites and a new consumer site added to the first storage network utilizing a cloud scale persistent message bus. In this method, the data is synchronized based on the recreated transaction history during the predetermined period of time and current transactions performed on each consumer site in the set of consumer sites. Apparatus, systems, and computer program products that can include, perform, and/or implement the methods are also disclosed herein.

Abstract: A computer-implemented method according to one embodiment includes identifying data stored within a first virtual storage tier of a storage system, analyzing one or more characteristics of the data, and conditionally transferring the data from the first virtual storage tier of the storage system to a second virtual storage tier of the storage system, based on the analyzing.
