Abstract
A method of site isolation protection includes the following steps. A set of clustered engines including a first engine at a first site and a second engine at a second site is provided. A Fiber Channel (FC) connection and an Ethernet connection between the first and the second sites are provided. Whether an Ethernet Heartbeat (EH) from one of the first engine and the second engine through the Ethernet connection exists is detected when the FC connection fails. One of the first engine and the second engine is shut down when the EH exists. Furthermore, a quorum service at a client site is provided in different IP domain to further protect site isolation from happening, while the FC connection and Ethernet Heartbeat connection failed at the same time.
Claims20
A method of site isolation protection, comprising steps of:
- providing a set of clustered engines including a first engine at a first site and a second engine at a second site;
- providing a Fiber Channel (FC) connection and an Ethernet connection between the first and the second sites;
- detecting whether an Ethernet Heartbeat (EH) from one of the first engine and the second engine through the Ethernet connection exists when the FC connection fails;
- and
- shutting down one of the first engine and the second engine when the EH exists.
A system having site isolation protection, comprising:
- a set of engines deployed at at-least-two sites;
- a first transmission connection between the at least two sites;
- a second transmission connection transmitting at least one transmission heartbeat (TH) between the at least two sites;
- and
- a service detecting at least one of a first state of the first transmission connection and a second state of an existence of the at least one TH, and issuing a specific command to the set of engines when the service determines that at least one of the first state and the second state meets a specific criterion.
An electronic device for use with site isolation protection, wherein two sites each has a set of engines, comprising:
- a first module detecting at least one of a first state of a data connection between the two sites, and a second state of an existence of a link connection between the two sites;
- and
- a second module issuing a specific command to the set of engines when the first module determines that at least one of the first state and the second state meets a specific criterion.
