Abstract
A storage system for use with a node device, includes host modules that access the node device based on an address conversion information. The node device is connectable to the host modules and includes the address conversion information.
Claims38
A storage system for use with a node device, said storage system comprising:
- host modules that access the node device based on an address conversion information,
- wherein said node device is connectable to said host modules and includes said address conversion information.
A storage system for use with a host adapter, said storage system comprising:
- node devices;
- and
- a host computer that accesses said node devices,
- wherein said host adapter is connectable to said host computer and controls data transfer between said host computer and said node devices, and said host adapter includes said address conversion information.
A host adapter within a storage system, said storage system comprising:
- a host computer, wherein:
- said node device is connectable to said host computer and includes an address conversion information;
- and
- the host adapter controls data transfer between said host computer and said node device based on said address conversion information.
A host adapter within a storage system, said storage system comprising:
- node devices;
- and
- a host computer that accesses said node devices,
- wherein said host adapter comprises:
- an address conversion information,
- wherein said host adapter is connectable to said host computer and controls data transfer between said host computer and said node devices.
A node device within a storage system, comprising:
- host modules that access the node device based on an address conversion information,
- wherein said node device comprises:
- said address conversion information,
- wherein said node device is connectable to said host modules.
A method of controlling a storage system for use with a node device, said storage system comprising:
- a host computer;
- and
- a host adapter that controls data transfer between said host computer and a node device based on an information of address conversion between said host computer and said node device, said node device being connectable to said storage system,
- wherein said method comprises:
- retrieving, by said host adapter, said address conversion information from said node device.
A method of controlling a host adapter within a storage system, said storage system comprising:
- node devices;
- and
- a host computer that accesses one of said node devices,
- wherein said host adapter is connectable to said host computer and controls data transfer between said host computer and said node device, said host adapter including information of address conversion between said host adapter and said node device,
- wherein said method comprises:
- increasing a number of said host adapter;
- and
- said host adapter writing said address conversion information to one of said node devices.
