Chapter 34: Management

Managing the physical infrastructure of a planetary scale computer is an enormous operational challenge. With thousands of servers across multiple facilities, hardware failures are a daily occurrence. Disks fail, memory develops errors, network cards malfunction, and entire servers become unresponsive. Effective infrastructure management requires automation at every step: detection, diagnosis, remediation, and replacement.

Automated hardware management systems track the inventory, health, and lifecycle of every component. When a disk shows signs of impending failure (through SMART metrics), the system automatically drains traffic from the affected server, schedules a replacement, and migrates data to healthy replicas. When a server becomes unresponsive, the system power-cycles it and, if it fails to recover, marks it for physical repair.

Firmware and BIOS updates must be rolled out across thousands of servers with minimal disruption. This requires coordination with the scheduling system to drain work from servers before updating them, and validation that the update did not introduce regressions. The scale of these operations makes manual management impossible — everything must be automated and auditable.
