Edit: ignore the below numbers, I got hours and minutes confused.
If you each sever spends 7.5 minutes each month rebooting, that is 1% of all your computers wasted. If you have 10,000 servers, that’s worth 100 severs. If you have 1 million servers, that’s worth 10,000 servers. If each server costs $10,000, that’s $100 million dollars of compute capacity. You can see how that amount of lost computer capacity can start to justify spending engineering time on driving down the amount of time servers are rebooting.
- sghiassy 3y agoThere’s 1,440 minutes per day. In a month with 30 days that’s 43,200 minutes per month. 7.5min/43,200min = 0.00017361 Where are you getting 1% of all your computers wasted per month???

- MarkSweep 3y agoSorry I got hours and minutes confused and overstated the benefits. So the correct numbers would be 7.5 minutes of downtime divided by 43,200 minutes times 1,000,000 servers. That’s 173 servers wasted. That is probably still enough servers wasted to devote some engineering time to increasing utilization.
- cortesoft 3y agoCapacity is measured by peak usage, but most data centers experience a daily traffic cycle with low times at night. We just patch/upgrade our servers at the local low time, when traffic is much lower and a lot of your machines are idle.
