And really, really expensive to replace. For just that Montreal Protocol reason. Besides, you have good backups and checkpoints, right? If your cluster catches fire, you order up a new cluster ³from the cloud² and continue work. Doesn¹t Amazon deliver these with big autonomous octocopters now?<grin>
But realistically,the need for ³non-damaging fire suppression² has gone away for a lot of data centers, since they have to have good disaster response plans with very fast response times compared to the 70s and 80s when ³batch² ruled the day. Imagine if you¹re handling stock transactions, or even something as mundane as home loans, with fairly tight time limits and downtime requirements. The regulators aren¹t going to be interested in your story about how you had all that Halon in your one data center, and then a flood wiped you out. If you¹ve got a geographically dispersed hot standby (or even just load sharing), you can use water to put the fire out enough to save lives, and let insurance haggle about the equipment replacement.
