The servers.

Four machines do the work. Two Dells run Proxmox, a Mac mini runs macOS CI, and a Raspberry Pi is the control node.

TD-LAB-02 · The servers The four machines that run things, each drawn from the front at the same scale. Dell PowerEdge R730 (U13–14): 2 × Xeon E5-2683 v4, 64 threads, 512 GB, eight drives in three zfs pools, Proxmox VE 9.2; runs 3 Talos nodes, GitHub runner, omp-cloud. Dell PowerEdge R430 (U12): 2 × Xeon E5-2620 v3, 24 threads, 48 GB, two 500 gb ssds in one zfs mirror, Proxmox VE 9.2; runs robomp. Mac mini (Top shelf): Apple M1, 8 cores, 16 GB, 1 tb ssd, macOS; runs macOS CI jobs, each in a throwaway macOS VM. Raspberry Pi 4 Model B (Top shelf): Broadcom BCM2711, 4 cores, 8 GB, Raspberry Pi OS; runs The tie-breaker for the two Proxmox hosts.
