US Patent:

7983171, Jul 19, 2011
Filed:

Sep 30, 2008
Appl. No.:

12/241836
Inventors:

Juan A. Coronado - Tucson AZ, US
Roger G. Hathorn - Tucson AZ, US
Bret W. Holley - Tucson AZ, US
Clarisa Valencia - Tucson AZ, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G01R 31/08
G06F 11/00
G08C 15/00
H04J 1/16
H04J 3/14
H04L 1/00
H04L 12/26
US Classification:

370241, 714 1
Abstract:

A failure threshold host command that provides a host with the capability to tune a storage controller path failure threshold based on the host application performance requirements. The failure threshold host command comprises path failure threshold rules that the storage controller uses to determine when a CHPid has reached a failed state condition.

US Patent:

8027263, Sep 27, 2011
Filed:

Sep 30, 2008
Appl. No.:

12/241883
Inventors:

Juan A. Coronado - Tucson AZ, US
Roger G. Hathorn - Tucson AZ, US
Bret W. Holley - Tucson AZ, US
Clarisa Valencia - Tucson AZ, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

H04J 1/16
US Classification:

370248, 370252
Abstract:

A system for providing hosts with a capability to determine which threshold rule of a plurality of threshold rules to use based upon threshold consensus. For example, the system would address a configuration case of several hosts sharing an output port of a fabric via zoning and that port being connected to a single port of a storage controller. If one host is executing lower priority jobs and its threshold is much higher than another host with higher priority jobs and a lower threshold, and the storage controller recognizes that several hosts are sharing the same storage controller port, the consensus will be to ignore the threshold of the first host and to use the threshold of the second host to prevent performance degradation in the system.

US Patent:

8108732, Jan 31, 2012
Filed:

Jun 18, 2008
Appl. No.:

12/141866
Inventors:

Juan Alonso Coronado - Tucson AZ, US
Roger Gregory Hathorn - Tucson AZ, US
Bret Wayne Holley - Tucson AZ, US
Clarisa Valencia - Tucson AZ, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G06F 11/00
US Classification:

714 43, 714 41, 714 472, 714 48, 714 56, 714 57, 370225
Abstract:

A method to minimize performance degradation during communication path failure in a data processing system, comprising a host computer, a storage controller, and a plurality of physical communication paths in communication with the host computer and the storage controller, where the method establishes a threshold communication path error rate, and determines an (i)th actual communication path error rate for an (i)th physical communication path, wherein that (i)th communication path is one of the plurality of physical communication paths. If the (i)th actual communication path error rate is greater than the threshold communication path error rate, the method discontinues use of the (i)th physical communication path.

US Patent:

8161455, Apr 17, 2012
Filed:

Jan 31, 2008
Appl. No.:

12/023617
Inventors:

Ezequiel Cervantes - Tucson AZ, US
Minghao M. Chu - Tucson AZ, US
Juan A. Coronado - Tucson AZ, US
Dinh Hai Le - Tucson AZ, US
Eric S. Shell - Tucson AZ, US
Clarisa Valencia - Tucson AZ, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G06F 9/44
US Classification:

717115, 717119
Abstract:

A method to concurrently execute multiple primitive commands in a command line interface (CLI) is provided. Each of a plurality of signal parameters is designated for each of a plurality of primitive commands. The plurality of primitive commands is encapsulated into a header CLI command. The CLI command is executed.

US Patent:

20090177911, Jul 9, 2009
Filed:

Jan 3, 2008
Appl. No.:

11/969187
Inventors:

Brian Dow Clark - Tucson AZ, US
Juan Alonso Coronado - Tucson AZ, US
Dinh Hai Le - Tucson AZ, US
Beth Ann Peterson - Tucson AZ, US
Clarisa Valencia - Tucson AZ, US
International Classification:

G06F 11/07
US Classification:

714 3, 714E11023
Abstract:

An apparatus, system, and method are disclosed to prevent queue stalling. The apparatus to prevent queue stalling is provided with a plurality of modules configured to functionally execute the necessary steps of detecting a connection failure on a first logical path, wherein the first logical path is associated with a first entry in a queue, and wherein the first logical path is configured to define a communication path between an entity associated with a first entry in the queue and a queue manager, scanning the queue to identify a second entry associated with a second logical path in response to the connection failure, and advancing the second entry to a position within the queue that is ahead of the first entry. These modules in the described embodiments include a detection module, a scanning module, and an advancing module.
