Abstract
A data storage system, device, and method are provided for replicating data between different data storage systems or appliances. More specifically, the present invention allows an initiating data storage device to pull data from a target data storage device. Thus, the storage device that is supplying the data can act as a target and does not require the additional software inherent in being an initiator.
Claims20
A method of communicating between data storage devices, comprising:
- a first data storage system using a first communication protocol to communicate with a first set of devices;
- at least a second data storage system using a second communication protocol to communicate with a second set of devices;
- employing a bridge communication protocol that that is used by both the first and the at least a second data storage system;
- and
- the first data storage system communicating with the at least a second data storage system via the bridge communication protocol.
2 more elements
An electronic data system, comprising:
- first data storage means having a first set of communication capabilities that allow the first data storage means to communicate with a first set of devices;
- second data storage means having a second set of communication capabilities that allow the second data storage system to communicate with a second set of devices;
- and
- bridging means providing communication capabilities between the first and second data storage means.
1 more element
A device for use in conjunction with data storage, comprising:
- an interface for communicating with at least a first data storage system comprising a first set of communication capabilities that allow the first data storage system to communicate with a first set of devices;
- and
- a processor operable to employ a bridge communication protocol that allows a second data storage system to communicate with the first data storage system, wherein the second data storage system comprises a second set of communication capabilities that allow the second data storage system to communicate with a second set of devices.
