yes i will be at NAB.. the linux config guide describes the 8gpu config… four GPUs per HBA to supermicro chassis is the only recommended 8GPU config, this SM is connected by 56Gbit Infiniband to a second SM that holds GUI, I/O etc….most of the hollywood guys use a config like this… as do hundreds around the world who want the full 8GPU power….. the linux license comes with the bmd panels, as does a second dongle for mac/windows, .
