Getting all the equipment 24 inches off the floor saves you from a pretty big fraction of events. You can often mostly protect against fairly severe events with sump pumps and flood barriers, but some water almost always gets in. If nothing important is on the ground you'll often still be OK.
- dylan604 2y agoFor a datacenter that does not exist on a coastline susceptible to hurricanes, you might have a point. However, we're specifically discussing a cluster of datacenters near Tampa which just missed a direct hit from a very powerful hurricane that had a forecast of a storm surge of 12'-15'. The thing to remember about storm surge is the predicted height does not include the height of wind driven waves on top of that surge. So unless your data center racks are on the 3rd floor, you are screwed
- mlyle 2y agoYes, I am not saying that you can withstand any event. I have seen >3' of water next to a building with infrastructure in the ground level that were fine, though. Seepage barriers and sump pumps and elevating things a little bit can do more than you'd think. It's also worth noting that however high the storm surge is -- your infrastructure is probably at least a little above sea level.
