Oxygen suppresion doesn't damage the equipment. Good luck cleaning out your equipment after you spray fire extinguisher all over them.

All the fire extinguishers GP linked use either FM200 or equivalent clean agents. They're not "conventional" fire extinguishers. :)

> "it's only a matter of time until Lithium chemistry batteries are available and that also increases the risk of fire." Not all Li-ion chemistries are equal. In particular, the increasingly popular LiFePO4 (LFP) technology has much higher energy density, longer lifespan, improved environmental characteristics, and similar if not better safety characteristics compared to lead-acid. (Besides sharing lead-acid's very l…

> lead-acid's very low risk of fire Isn't lead-acid prone to releasing hydrogen gas? When jump-starting a car, it is commonly recommended to connect the ground (black) cable to the chassis, not to the battery's black terminal, to avoid a spark igniting the hydrogen and causing an explosion.

My old company's DC uses FM200 gas which puts fires out without asphyxiating anyone (I'm assuming the experience would be a respiratory workout for anyone caught in it, but it would have cost £20000 to test).

Are there industry options or methods of wiring to allow for a UPS room separate from the actual rooms the racks are stored in? It's almost tradition to have a rack with UPS's in the bottom and then the rest of the space filled with servers or drive arrays. We wouldn't ever think of putting a tiny backup generator in the bottom of every rack, so why do we put a battery storage system there? Also, with the advances in…

For the extreme opposite of that, Google famously trolled everyone 10 years ago by announcing that every one of their servers had its own in-chassis 12V battery: https://www.cnet.com/news/google-uncloaks-once-secret-server...

This would be one of inherient difference between smaller vs. giga players in cloud hosting. AWS/Google/Azure, if this happens, there should only be limited outage to a small fraction of customers. As a matter of fact, Google had such an incident before, and literally no customers (internal and external) noticed.

This is a difference in what you are buying. When you are buying a dedicated server, there isn't exactly a good way to hide that the thing has just gone up in smokes. When you buy a storage API, sure, failure rates go up, latency increases 100x, but after a few hours its probably back to normal. Of course, with the increased abstraction, you get more problems. "Availability zones" are useless when most cloud outages…
