• 1x dedicated local SSD mounted under /var/lib/etcd
• 1x dedicated slow disk for the OS
• 2x CPUs

• etcd may use maximal memory if one follower is dead and the leader keeps sending snapshots.
• is the maximal memory usage recorded in 3 runs.

• For most cases, the etcd cluster should work smoothly if it doesn’t hit the threshold. If it doesn’t work well due to insufficient resources, decrease its data size.
