Patent number: 11115340Abstract: Aspects of the invention include receiving an input/output (I/O) request that includes a data stream from a host processor. The receiving is at a network adapter of a storage controller that manages storage for the host processor. The storage controller includes a storage buffer to store data received from the host processor before migrating it to the storage. The storage controller also includes a data cache. It is determined whether the storage buffer has enough free space to store the received data stream. Based at least in part on determining that the storage buffer has enough free space to store the received data stream, the received data stream is stored by the network adapter in the storage. Based at least in part on determining that the storage buffer does not have enough free space to store the received data stream, the received data stream is stored in the data cache.Type: GrantFiled: June 26, 2018Date of Patent: September 7, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Christoph Raisch, Kishorekumar G. Pillai, Alol Antony Crasta, Raghavan Devanathan

Patent number: 11055108Abstract: A method, computer program product, and system includes a processor(s) connecting a first computer system to a boot swarm, initiating formation of a peer to peer network. The processor(s) receive a request from a second computer system, a request for a file. The processor(s) configure the second computer system, including implementing a client application hosted from a resource in the first computer system, to facilitate the second computer system joining the peer to peer network. The processor(s) determine immediate peer(s) in the peer to peer network available to provide the file to the second computer system. The processor(s) generate a magnet link that includes a listing of address(es) of the immediate peer(s), ranking address(es) from best source to worst source for downloading the file. The processor(s) provide the second computer system with the magnet link to utilize in downloading the file from a peer.Type: GrantFiled: December 16, 2019Date of Patent: July 6, 2021Assignee: International Business Machines CorporationInventors: Alol A.

Patent number: 10979239Abstract: A computer system includes a first server including a first data management module and a second server including a second data management module, and a first and second storage controller. The first and second storage controllers are interconnected by a network configured for reliable data multicasting. The computer system further includes a cross system manager for controlling one or more core storage functions on each of the first and second storage controllers. The computer system further includes computer program instructions to, responsive to a core storage function triggered by the cross system manager: Create a multicast group for each of the first server and the second server in the network, wherein the multicast group is created by a reliable multicast mechanism, and Multicast data write operations of each of the first server and the second server to the first storage controller and the second storage controller of the multicast group.Type: GrantFiled: June 11, 2019Date of Patent: April 13, 2021Assignee: International Business Machines CorporationInventors: Alol A.
