and so do I.
No post-whoring .
Work? What's that?!?
I have been closing my eyes, hoping it will go away, but it hasn't
Do some work? :thumb:
Without going into too much detail, the servers are going to be moved not quite like Jim mentioned but will be placed in another rack within the same room. However, they will be installed on a central UPS giving higher availability to all thesite.org users. This is a good thing. The downtime is expected to be about 8 hours due to the sheer amounts that have to be moved. More info as I get it.
shutdown, disconnect, slide out, remove from rails. -3 minutes
remove rails - 5 mins.
install rails in new rack. - 15 mins
drop into rails, slide in, reconnect, reboot - 5 mins.
I just hope you're not paying more than 3K/year
Yeah, for one box maybe. If it goes perfectly.
Plus some machines these days take up to twenty minutes to power down and come back up.
Plus they have to repatch loads of stuff by the sounds of it, which is probably sitting in a spaghetti behind the racks.
Then around 3% of the machines won't come back on at all.
So, given it all, 8 hours is probably optimistic
Unscheduled downtime is another matter. It drives me bonkers .
That's a busy machine. I'd be alarmed if a controlled shutdown took longer than a minute, and a startup after a controlled shutdown took more than 5.
You prepare the new location before moving the machine, and clean up the old once it has been moved.
Yes, a computer is most vulnerable when it is being turned on.
For moving a whole rack we would warn our customers that their servers would be likely to be down for up to half an hour between 11pm and 7 am; our target downtime would be 10 minutes for each server.
