Hi TimJRoberts1,
We officially support 1,000 nodes and 16,000 cores (16 cores per node X 1000). In our scale test environment, the nodes and cores sometimes may reach 2,000 nodes and 20,000 cores. It is feasible to have a single head node instead of clustered high-availability
head nodes for easy setup and maintenance, however a remote SQL database with
scale configurations and high hardware spec machines (e.g.
2*E5-2660V2 @ 2.20GHz, 12*16=192GB RAM, 8* 600GB 15K RPM HDD, 1Gb NIC) are required for the large scale cluster.
Regards,
Yutong Sun
