Does commodity hardware guarantee lower power consumption?
No, it does not inherently guarantee significantly lower power consumption or zero downtime.
What components are typically found in servers?
- CPUs
- RAM
- Hard disks
- Network cards
What is a server rack?
A metal framework that houses multiple servers, networking devices, and other IT equipment.
What is a top of rack switch?

Which statement best describes why ‘commodity hardware’ is chosen for data centre servers?
It is both cost-effective and readily available ‘off the shelf,’ offering standard components that can be replaced easily.
what do top-of-rack switches do?
They serve as the local switching point for all servers in a rack, and connect those servers to the broader data centre network.
