## Resources (RAM, CPU, etc.)
**Nomad servers** may need to be run on large machine instances. We suggest
having 8+ cores, 32 GB+ of memory, 80 GB+ of disk and significant network
bandwidth. The core count and network recommendations are to ensure high
throughput as Nomad heavily relies on network communication and as the Servers
are managing all the nodes in the region and performing scheduling. The memory
and disk requirements are due to the fact that Nomad stores all state in memory
and will store two snapshots of this data onto disk. Thus disk should be at
least 2 times the memory available to the server when deploying a high load
cluster.
having between 4-8+ cores, 16-32 GB+ of memory, 40-80 GB+ of disk and

The memory and disk requirements are due to the fact that Nomad stores all state

be at least 2 times the memory available to the server when deploying a high
load cluster.
These recommendations are guidelines and operators should always monitor the
resource usage of Nomad to determine if the machines are under or over-sized.
**Nomad clients** support reserving resources on the node that should not be
used by Nomad. This should be used to target a specific resource utilization per
