Hi, We have a ROCKS cluster, but it is just Ethernet. Does the cluster have no Ethernet network? (Is this a planned cluster?) You need some way to build the nodes and the ROCKS way is PXE boot driven installs --- I'm not sure if you can PXE boot over Infiniband? Also, other node management stuff (IPMI) relies on Ethernet. I think Inifiband clusters normally have Ethernet for management and Infiniband for the data links. -Tom On 9/23/11 2:38 PM, Bill Park wrote: > Does anybody have any experience in building a rocks cluster using > infiniband to connect the compute nodes to the head node (where my > storage array is)?
