Hello, A convenient way to provide high availability when using fail-over between two IPv4 iSCSI servers is to configure the HA software such that a secondary IPv4 address is only assigned to the active server. I'd like to build a HA SRP setup using a similar approach. This leads me to the following question: does there exist an equivalent of virtual IP addresses for IB ? As far as I can see in the IBTA specs a subnet manager can assign a secondary GID to an IB HCA port dynamically.
Does any of the existing IB switches support this ? If so, how does communication between HA software and IB switch happen ? Does OpenSM support assigning secondary GIDs to a HCA port ? Thanks, Bart. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
