Abstract

A disk array system in accordance with the present invention comprises: a plurality of storage devices in which data is stored; a storage device control unit that controls storage of data in the plurality of storage devices; a connection unit connected to the storage device control unit; a first communication control unit; and a management terminal. The first communication control unit is connected to the storage device control unit via the connection unit, and connected on a first network external to the own disk array system, and transfers file data over the first network. The first communication control unit transfers data to the connection unit, and reads information on a fault occurring in the own disk array system from the plurality of storage devices so as to transfer the information to the management terminal. According to the present invention, there is provided a disk array system connectable on a plurality of different kinds of networks and a method of controlling fault information concerning the disk array system.

Claims

1. A disk array system comprising:

a plurality of storage devices in which data is stored;

a storage device control unit that controls storage of data in said plurality of storage devices;

a connection unit connected to said storage device control unit; and

a first communication control unit that is connected to said storage device control unit via said connection unit, and connected on a first network external to said own disk array system, and that transfers file data over said first network, wherein;

said first communication control unit comprises;

a first processor that associates file data, which is transferred over said first network, with block-form data that is stored in said storage device control unit; and

a second processor that transfers data in response to a request made by said first processor, and that reads information on a fault occurring in said own disk array system from said plurality of storage devices in response to a request made by said first processor, and transmits the information to said first processor.
