STORAGE CONTROLLER, STORAGE SYSTEM AND METHOD OF OPERATING STORAGE CONTROLLER

摘要

A redundant array of independent disks (RAID) storage system, includes a RAID master controller receiving a RAID request selectively communicating the RAID request to one of a plurality of storage devices, wherein first and second storage devices are directly connected outside a data communication path including the host among the storage devices. The first storage device determines upon receiving the RAID request whether distribution of a RAID sub-request to the second storage device is necessary, such that upon determining that the distribution of a RAID sub-request is necessary, the first RAID controller communicates the RAID sub-request to the second storage device via the direct network connection.

1. A redundant array of independent disks (RAID) storage system, comprising:
a RAID master controller that receives a RAID request; a first storage device including;
a first RAID processing unit that receives the RAID request from the RAID master controller and determines whether distribution of a RAID sub-request is necessary, wherein upon determining that the distribution of a RAID sub-request is not necessary the RAID processing unit directly processes the RAID request; anda first RAID request distributing unit that upon determining that the distribution of a RAID sub-request is necessary, communicates the RAID sub-request to a second storage device via a direct network connection between the first storage device and second storage device.
