The 7.2 earthquake two weeks ago in Turkey got me thinking again about disaster preparedness and IT. It reminded me of the 5.9 earthquake that occurred on the U.S. east coast, a region that is not supposed to get earthquakes. I just did a couple of walk-throughs at two different client facilities. One had server racking very well secured at the top and bottom that looked like it would withstand a pretty severe shaking while the other site did not have any fasteners at either the top or the bottom of the server racks. I could have pushed the racks over myself by leaning on them.
Smoke testing is a term used to describe the testing process for servers after patches are applied.
The process typically involves making sure servers are rebooted in the right order, making sure they have completely rebooted, restarting applications in the right order, and then testing to be certain everything is working properly when users return to work in the morning.
This typically takes 30 minutes per server, depending upon your environment.
PCs are not typically smoke tested, or if so, not all of them.
