IDENTIFYING WORKLOAD AND SIZING OF BUFFERS FOR THE PURPOSE OF VOLUME REPLICATION

摘要

A controller is operable to: identify virtual machines to be protected in a first storage system; identify logical volumes used by the virtual machines based on first relationship information; calculate workload, based on information of workload monitored for the identified logical volumes; and calculate size of a buffer area in the first storage system to be used for temporarily storing copy data to be sent to a second storage system in remote copy procedure of one or more remote copy pairs, based on the calculated workload, each copy pair being formed by a logical volume of the identified logical volumes in the first storage system as primary logical volume and another logical volume in the second storage system as secondary logical volume, so that the buffer area having a size equal to or greater than the calculated size can be used to manage protection of the identified virtual machines.

主权项

1. A computer comprising a memory and a controller, the controller being operable to:
identify one or more virtual machines of a plurality of virtual machines to be protected in a first storage system; identify one or more logical volumes of a plurality of logical volumes in the first storage system, the one or more logical volumes used by the identified one or more virtual machines, based on first relationship information between the plurality of virtual machines and the plurality of logical volumes, the first relationship information being managed by the controller; calculate a workload to be used for the identified one or more logical volumes, based on information of workload monitored for each of the identified one or more logical volumes, the information of workload monitored being managed by the controller; and calculate a size of a buffer area in the first storage system to be used for temporarily storing copy data to be sent from the first storage system to a second storage system in a remote copy procedure of one or more remote copy pairs, based on the calculated workload of the identified one or more logical volumes, each of the one or more remote copy pairs being formed by a logical volume of the identified one or more logical volumes in the first storage system as a primary logical volume and another logical volume in the second storage system as a secondary logical volume, so that the buffer area for the remote copy procedure of the identified one or more logical volumes having a size equal to or greater than the calculated size can be used to manage protection of the identified one or more virtual machines.
