Is this a single system image machine or a cluster in the traditional
sense? The MIPS based SGI Origins used some custom interconnects to
create a nice NUMA machine across different nodes.

If it's a single system, management and CPU/memory utilization would be
significantly easier compared to the cluster but how well does Linux
handle a NUMA environment?
