Performance separation optimization according to protocol usage status and storage system performance

摘要

For the purpose of optimizing the performance separation according to the usage status of the protocol and the storage system performance, in a storage system 1 including multiple storage devices 2400 which includes a storage controlling unit 2410 performing data write to or data read from a storage drive 2200 according to data input/output requests from an external device 1000 and a protocol processing unit 2514 that responds to a processing result for the input/output requests to the external device 1000 and is capable of responding to data input/output requests transmitted from the external device 1000 following at least two or more protocols, in which each of the storage devices 2400 includes a cluster processing unit 2516 configuring clusters 2811 with the other storage devices 2400 for the external device 1000 and a cluster processing unit 2516, the cluster processing unit 2516 is set to configure cluster groups 2812 for each protocol.
