Patent
Method and apparatus for creating and identifying logical partition clusters
William J. Rooney,Harry M. Yudenfriend,Jeffrey P. Kubala,Eugene P. Hefferon,Carol B. Hernandez +4 more
TL;DR: The logical partition cluster (LPC) as mentioned in this paper is a method for creating and identifying different kinds of groups of cooperating system images within a single machine, a single central processor complex (CPC), where each kind of group has a different functional purpose.
Patent
Facilitating transport mode input/output operations between a channel subsystem and input/output devices
Susan K. Candelaria,Scott M. Carlson,Daniel F. Casper,John R. Flanagan,Roger G. Hathorn,Matthew J. Kalos,Louis W. Ricci,Dale F. Riedy,Harry M. Yudenfriend +8 more
TL;DR: In this article, a computer program product is configured for performing a method including: generating at least one command message by a channel subsystem of the host computer system, the command message including one or more device command words (DCWs), wherein one DCW of the one or multiple DCWs includes a suppress-length indication (SLI) configured to instruct a control unit to continue to perform the I/O operation in response to the control unit detecting that the data count does not match an amount of data required.
Patent
Communicating Packets Between Devices Involving the Use of Different Communication Protocols
Wayne Charles Carlson,Erika Marianna Dawson,Gavin S. Johnson,Trang Thuy Le,Matthew Hank Sabins,Peter G. Sutton,Harry M. Yudenfriend +6 more
TL;DR: In this paper, the authors describe a method, system, and article of manufacture for receiving an initial request from a first device to a second device, where a response to the initial request is received from the second device to the first device.
Patent
Generating a chain of a plurality of write requests
Jeffrey A. Berger,Susan K. Candelaria,Matthew J. Kalos,Beth A. Peterson,Harry M. Yudenfriend +4 more
TL;DR: In this article, the commit wait flag is set to one of an indicated first value or a second value to cause a storage server to process the write requests by requiring a current write request being processed to complete before transferring data for a next write request following the current request.
Patent
Maintenance of a fabric priority among operations in related fibre channel exchanges
TL;DR: In this paper, a method, a system, and a computer program that use a Fibre Connection (FICON) protocol is presented, in which a first device that is coupled to a second device receives an outbound exchange from the second device, wherein one or more Fibre Channel frames of the inbound exchange have an identical priority to the priority indicated by the first device in the outbound transmission.
