 ### Hosts
 - **c1, c2, c3**: Cattle nodes, run most workloads, Nomad/Consul quorum members
-- **zippy**: Primary NFS server, runs workloads (affinity), NOT quorum, replicates to c1 every 5min
+- **sparky**: Primary NFS server, runs workloads (affinity), NOT quorum, replicates to c1 every 5min
 - **chilly**: Home Assistant VM, cluster member (Consul agent + CLI tools), no workloads
-- **sparky**: Desktop/laptop, cluster member (Consul agent + CLI tools), no workloads
+- **sparky**: Nomad worker
+- **beefy**: Desktop/laptop, cluster member (Consul agent + CLI tools), no workloads
 - **fractal**: Storage node (Proxmox/ZFS), will join quorum after GlusterFS removed
 - **sunny**: Standalone ethereum staking node (not in cluster)
