Cluster Configuration
In a cluster where multiple 10 GbE Gateway ports are connected in parallel to each other (both
on the Ethernet side and the InfiniBand side), these modules behave in High Availability and
Load Balancing mode as described below. They automatically detect each other and are
displayed in the Cluster Configuration window Active Node data according to priority.
Note that if two 10 GbE Gateway ports have the same priority, they are sorted according to the
master bit and then by the serial number. The 10 GbE gateway that has the highest priority
becomes Master when there is no other 10 GbE gateway acting as master. If there is already a
master in the system, it will stay the master even though its priority is lower.
Multiple algorithms are available for distributing traffic between multiple sRB-20210G
Gateways in Cluster Mode. The traffic can be balanced between the sRB-20210G Gateways
according to the load balancing algorithm (options: active-active, master-standby). In
active-active mode, the load balancing is performed according to the Hash Algorithm (options:
XOR IB Eth, IB, Eth).
