Merlin6 cluster connectivity is based on the [Infiniband](https://en.wikipedia.org/wiki/InfiniBand) technology. This allows fast access with very low latencies to the data as well as running
extremely efficient MPI-based jobs:
* Connectivity amongst different computing nodes on different chassis ensures up to 1200Gbps of aggregated bandwidth.
* Inter connectivity (communication amongst computing nodes in the same chassis) ensures up to 2400Gbps of aggregated bandwidth.
* Connectivity amongst different computing nodes on different chassis ensures up to 1200Gbps of aggregated bandwidth.
* Inter connectivity (communication amongst computing nodes in the same chassis) ensures up to 2400Gbps of aggregated bandwidth.
* Communication to the storage ensures up to 800Gbps of aggregated bandwidth.
Merlin6 cluster currently contains 5 Infiniband Managed switches and 3 Infiniband Unmanaged switches (one per HP Apollo chassis):
