Title
(EN) IDENTIFICATION AND CONTAINMENT OF PERFORMANCE HOT-SPOTS IN VIRTUAL VOLUMES
(FR) IDENTIFICATION ET ISOLEMENT DE ZONES ACTIVES DE PERFORMANCES DANS DES VOLUMES VIRTUELS
Abstract
(EN)
A method includes provisioning a virtual volume from at least one storage pool of a storage array, designating at least one virtual volume segment of the virtual volume for mapping a virtual volume range to a virtual drive range, organizing the virtual volume range into a plurality of clusters, measuring a data load on each of the plurality of clusters and comparing the data load on each of the plurality of clusters to activity of the virtual volume, and reconfiguring the at least one virtual volume segment to contain a hot- spot.
(FR)
Procédé comprenant les étapes consistant à : créer un volume virtuel à partir d’au moins un groupement d’unités de stockage d’une baie de stockage ; désigner au moins un segment du volume virtuel pour mettre une plage du volume virtuel en correspondance avec une plage d’un disque virtuel ; organiser la plage du volume virtuel en une pluralité de groupes ; mesurer une charge de données sur chacun de la pluralité de groupes et comparer la charge de données sur chacun de la pluralité de groupes à l’activité du volume virtuel ; et reconfigurer le ou les segments du volume virtuel pour isoler une zone active.
