From my experience that should all be sufficient. The real key is the
high clock rate CPU and sufficient memory. SSD's for the slurm spool
directory is good too. You will want to put CentOS7 on this at least
and run the latest version of MariaDB as well.

Head Node Hardware Requirements
Hi, All,
I am gathering hardware requirements for head nodes for my next
cluster. The new cluster will have ~1500 nodes. We ran 5 million jobs
last year. I plan to run the slurmctld on one node and the slurmdbd on
another. I also plan to write the StateSaveLocation to an NFS
appliance. Does the following configuration look sufficient?
Node1:
slurmctld
128GB ram
2TB local disk
12 core high clock rate CPU
Node2:
slurmdbd
slurmctld backup
128GB ram
2TB local disk
mirrored 500GB SSD for database
12 core high clock rate CPU
Do I need more RAM in either node? Is12 cores enough? Is 500GB large
enough for the Slurm database?
