(EN) CONNECTION LOAD DISTRIBUTION IN DISTRIBUTED OBJECT STORAGE SYSTEMS
(FR) DISTRIBUTION DE CHARGE DE CONNEXION DANS DES SYSTÈMES DE STOCKAGE D'OBJETS RÉPARTIS
Abstract
(EN)
An example system comprises a first access node in a first rack configured to engage in a connection with a client, and a second access node in a second rack. The first and second racks form a multi-rack distributed storage system. The system includes a distributed database including a first load indicator designating a first processing load of the first access node and a second load indicator designating a second processing load of the second access node. The distributed database is accessible to the first and second access nodes. The system further includes a connection relocation manager configured to relocate the connection with the client from the first access node to the second access node when the second processing load is less than the first processing load.
(FR)
Un système donné à titre d'exemple comprend un premier nœud d'accès dans un premier bâti configuré pour s'engager dans une connexion avec un client, et un second nœud d'accès dans un second bâti. Les premier et second bâtis forment un système de stockage distribué à plusieurs bâtis. Le système comprend une base de données distribuée comprenant un premier indicateur de charge désignant une première charge de traitement du premier nœud d'accès et un second indicateur de charge désignant une seconde charge de traitement du second nœud d'accès. La base de données distribuée est accessible aux premier et second nœuds d'accès. Le système comprend en outre un gestionnaire de relocalisation de connexion configuré pour relocaliser la connexion avec le client du premier nœud d'accès au second nœud d'accès lorsque la seconde charge de traitement est inférieure à la première charge de traitement.
