That's not that rare these days. Basically any server will allow hot-plugging hard drives, with some configurations network cards and by now a lot of laptops can even hot-plug GPUs via Thunderbolt.

- rbanffy 4y agoI remember some big iron could do it with processors and memory as well. IIRC, you can no longer remove CPUs with IBMs, but replacing memory is relatively simple.
- neverartful 4y agoHot-plugging hard drives is a bare minimum. There are many other points of failure and a failure of any of the following WILL result in downtime while the component is replaced: disk controller, CPU, memory, NIC. Having dual NICs and dual processors helps, but it's still a far cry from 100% availability.
