Maximum links in M*N Remote copy configuration
Hi
form 3par documentation:
In an M-to-N Remote Copy configuration, bidirectional data replication takes place in a 4x4 fan-in, fan-out configuration.
Data replication occurs without the need for dedicated Remote Copy pairs. The transport layer can be RCFC, RCIP, or FCIP, or a mixture of these, with up to five links per node. Only one RCIP link per node is possible; the other links can be RCFC or FCIP.
Question1 : no more than 4 device can participate in RCP scenario?
Question2:one node in above text means a controller or a device as whole ?
Question3:what does it mean up to 5 link ? 1 link per controller port or anything other ?
Thanks alot

Re: Maximum links in M*N Remote copy configuration
Question1 : no more than 4 device can participate in RCP scenario?
Answer: See below
Question2:one node in above text means a controller or a device as whole ?
Answer: Node == Controller node == Controller. As opposed to the 3PAR StoreServ system as a whole.
Question3:what does it mean up to 5 link ? 1 link per controller port or anything other ?
Answer: Four FC links and one IP link per controller node.
A specific RCFC port can only link to one target system, no more.
A specific RCIP port can link to, at most, two target systems, no more.
