Fiber channel connection storage controller

A storage system adapted to be coupled to a plurality of host devices, the storage system comprising:

• a plurality of storage devices, at least a portion of the plurality of storage devices being related to a logical unit of a plurality of logical units, the logical unit corresponding to a logical unit number (LUN);
• a storage control device comprising a cache memory and controlling the plurality of storage devices as one or more RAID groups and controlling to store data, addressed to the LUN, into at least the portion of the plurality of storage devices;
• and
• an input device being adapted to be used to set information, which is set by the LUN of the logical unit and an identifier of a host device included in the plurality of the host devices, and which is used to prevent an unauthorized access to the logical unit.

A storage system adapted to be coupled to a plurality of host devices, the storage system comprising:

• a plurality of storage devices, at least a portion of the plurality of storage devices being related to a logical unit of a plurality of logical units;
• a storage control device comprising a cache memory and controlling the plurality of storage devices as one or more RAID groups and controlling to store data, which is requested to store in the logical unit, into at least the portion of the plurality of storage devices;
• and
• an input device being adapted to be used to set information, which is set according to the logical unit and a host device included in the plurality of the host devices, and which is used to prevent an unauthorized access to the logical unit.

A storage system adapted to be coupled to a plurality of external devices, the storage system comprising:

• a plurality of storage devices, at least a portion of the plurality of storage devices corresponding to a logical unit of a plurality of logical units, the logical unit corresponding to a logical unit number (LUN);
• a storage control device comprising a cache memory and controlling the plurality of storage devices as one or more RAID groups and controlling to store data, addressed to the LUN, into at least the portion of the plurality of storage devices in response to receipt of an access sent from the plurality of host devices using TCP/IP protocol;
• and
• an input device being adapted to be used to set information, which corresponds to a relationship between the logical unit and an external device of the plurality of external devices and which is used to prevent an unauthorized access to the logical unit.

A control method for a storage system, the storage system being adapted to be coupled to a plurality of host devices, the control method comprising the steps of:

• controlling a plurality of storage devices as one or more RAID groups;
• corresponding a least a portion of the plurality of storage devices to a logical unit of a plurality of logical units, the at least a portion of the plurality of storage devices being used for storing data, addressed to a logical unit number (LUN) corresponding to the logical unit, according to controlling of a storage control device comprising a cache memory;
• and
• managing information, which corresponds to a relationship between a host device of the plurality of host devices and the logical unit and which is set via an input device for preventing an unauthorized access to the logical unit.

A control method for a storage system, the storage system being adapted to be coupled to a plurality of host devices, the control method comprising the steps of:

• controlling a plurality of storage devices as one or more RAID groups;
• relating at least a portion of the plurality of storage devices to a logical unit of a plurality of logical units, the at least a portion of a plurality of storage devices being used for storing data, which is requested to be stored in the logical unit, by control of a storage control device comprising a cache memory;
• and
• managing information, which is set by using a first identifier of the logical unit and a second identifier of a host device included in the plurality of host devices and which is set via an input device for preventing an unauthorized access to the logical unit.
