Abstract:
1. A disk-array device comprising: a storage device which is connected to a server device on a network via a switch device; a plurality of control cluster devices each of which comprising a plurality of channel adapters configured to receive data from the switching device, a cache memory, a plurality of disk adapters and an interconnection switch device operatively connected between the plurality of channel adapters, the cache memory and the plurality of disk adapters, each control cluster device being configured so that the data from the plurality of channel adapters is stored in the cache memory and the data in the cache memory is outputted to the plurality of disk adapters; link-information management means for acquiring through an interface of said disk-array device respective link information among said server device, said switch device, and said storage device via said switch device so as to manage said link information in a combined manner; and collection/analysis means for retrieving and collecting desired combined information of said link information from said link-information management means so as to analyze said desired combined information, wherein said link information includes attribute information of an adaptor of said server device, said switch device, or the channel adaptors of said control cluster devices, and said attribute information includes a model number and a version number of a driving software or firmware, wherein concerning a compatibility between a link of a version of a host bus adapter (HBA) driver of said server device and a version of firmware of said switch device, an already-verified combination table is displayed in an in-batch manner, and wherein each of the plurality of control clusters has an independent power supply different from one another.
