Abstract: A computer controls deduplication of data. The computer generates a hash of a remote data and a hash of a local data. The computer generates a set of unmatched hash data based on a comparison of the hash of the remote data against the hash of the local data. The computer generates a splitting cost that is associated with splitting the set of unmatched hash data. The computer sends a request to a server based on a comparison of the splitting cost to a threshold. The request dictates sending of the remote data to a storage controller.

Abstract: A computer-implemented method includes receiving, by a storage controller, a hash data. The hash data includes a hash of a remote data. The method includes comparing, by the storage controller, the hash data against an index. The index includes one or more hashes of a local data. The method includes determining, by the storage controller, whether the remote data parallels any part of the local data, based on comparing the hash data with the index. The method is responsive to the remote data paralleling any part of the local data. The method includes sending, from the storage controller, a request to not transmit said remote data.

Abstract: A serial identification number of a system, the system having a system type and a system status is received. A database is accessed to obtain code detail records of the system associated with the serial identification number. Code details of the system are received. The serial identification number, the code detail records, and the code details of the system are analyzed to identify the system type and the system status. A suitable system update for the system, based on the system type and the system status is identified.
