Abstract
A virtualization control apparatus includes a selection unit that, when receiving a copy request, conducting an access test corresponding to the copy request on each of the virtualization switch units and selects one of the virtualization switch units of the highest performance among the plurality of the virtual switch units, and a sending unit that sends the copy request to the selected virtualization switch unit.
Claims7
A virtualization control apparatus of a storage system, the storage system including a plurality of storage controllers controlling a plurality of storage units connected thereto and a plurality of virtualization switch units being connected to one of the storage controllers, each of the virtualization switch units converting a copy source logical volume address and a copy destination logical volume address contained in a received copy request into addresses of the storage units and making a request to the storage controllers on the basis of the converted addresses, the virtualization control apparatus comprising:
- a selection unit that, when receiving a copy request, conducting an access test corresponding to the copy request on each of the virtualization switch units and selects one of the virtualization switch units of the highest performance among the plurality of the virtual switch units;
- and
- a sending unit that sends the copy request to the selected virtualization switch unit.
A virtualization control apparatus of a storage system, the storage system including a plurality of storage controllers that controls a plurality of storage units connected thereto and a plurality of virtualization switch units being connected to one of the storage controllers, each of the virtualization switch units converting a copy source logical volume address and a copy destination logical volume address contained in a received copy request into addresses of the storage units and making a request to the storage controllers on the basis of the converted addresses, the virtualization control apparatus comprising:
- a monitoring unit that monitors unevenness in copy performance of copy processes which process by each of the virtualization switches;
- a selection unit when detecting unevenness in the copy performance, suspending a copy process exhibiting copy performance lower than predetermined copy performance among the copy processes the virtualization switch units are performing, conducting an access test corresponding to the suspended copy process on each of the virtualization switch units, and selecting one of the virtualization switch units of the highest performance among the plurality of the virtual switch units;
- and
- a processing unit that resumes the suspended copy process using the selected virtualization switch unit.
A non-transitory computer-readable medium storing a program applied for a virtualization control apparatus of a storage system, the storage system including a plurality of storage controllers controlling a plurality of storage units connected thereto and a plurality of virtualization switch units being connected to one of the storage controllers, each of the virtualization switch units converting a copy source logical volume address and a copy destination logical volume address contained in a received copy request into addresses of the storage units and making a request to the storage controllers on the basis of the converted addresses, the program causing the virtualization control apparatus to execute:
- conducting, when receiving a copy request, an access test corresponding to the copy request on each of the virtualization switch units, and selecting one of the virtualization switch units of the highest performance among the plurality of the virtual switch units;
- and
- sending the copy request to the selected virtualization switch unit.
