Title
(EN) STATE-PRESERVING UPGRADE OF AN INTELLIGENT SERVER ADAPTER
(FR) MISE À NIVEAU PRÉSERVANT L'ÉTAT D'UN ADAPTATEUR DE SERVEUR INTELLIGENT
Abstract
(EN)
Methods and systems for upgrading an intelligent server adapter (ISA) with reduced downtime that affects performance are provided. The method includes, from a main agent, initiating a backup agent that includes critical functions of the ISA and runs in a tight loop, isolated from other components. The main agent transfers critical duties to the backup agent and shuts down before performing the upgrade. After upgrading itself and other system components, the main agent retrieves the duties from the backup agent, and may terminate the backup agent.
(FR)
L'invention concerne des procédés et des systèmes pour mettre à niveau un adaptateur de serveur intelligent (ISA) avec un temps d'arrêt réduit qui affecte les performances. Le procédé comprend, à partir d'un agent principal, l'initiation d'un agent de sauvegarde qui comprend des fonctions critiques de l'ISA et s'exécute dans une boucle bien ajustée, isolée vis-à-vis d'autres composants. L'agent principal transfère des tâches critiques à l'agent de sauvegarde et s'arrête avant d'effectuer la mise à niveau. Après sa mise à niveau et celles d'autres composants du système, l'agent principal récupère les tâches de l'agent de sauvegarde, et peut arrêter l'agent de sauvegarde.
