OPS Data centres & OPS Cloud
How it works, end to end.
Data halls
Racks, UPS, generators and CRAC cooling within 25 m form a hall. Racks need power (UPS or socket), a ToR switch and a CAT6 uplink to an online router.
Heat
Running servers make heat; CRAC units remove 30 kW each. Over 32 °C servers degrade; at 40 °C they shut down until it cools.
Power
On mains the UPS charges; in a power cut it runs on battery (longer at low load), then everything goes dark.
OPS Cloud
Customer VMs are placed on healthy 'cloud' role hosts in their region, restarted elsewhere when a host dies, or left 'host down' / 'waiting for capacity'.
Platform roles
Servers can run OPS Web hosting, OPS DNS or OPS mail. Once a role has servers, that service is down whenever none is reachable — websites time out, lookups fail, mail bounces.
