At a past company we moved offices in the same building (from the 3rd floor of a wing to the 10th floor of a tower), and the upstream data provider swore the line would be ready on the move data, "it was the same building" etc etc. Turns out the wing was serviced by a different central office, and the tower wasn't going to get a line until 60 days past the move in date. My bad for not forcing the vendor to do a site survey. <br /><br />We saved the day by dropping an ethernet cable from the 10th window, across the roof of the wing, and into a window on the old 3rd floor and then into the phone system, which the building owner let us keep there for a while. For 60 days we prayed nobody would lean out there window and cut the cable. <br /><br />Don't trust your vendors until you get them on site at the old and new location.Unknownhttps://www.blogger.com/profile/04161201682513694680noreply@blogger.comtag:blogger.com,1999:blog-3615332969083650973.post-85550530305022722802009-12-22T12:23:04.857-05:002009-12-22T12:23:04.857-05:00Quote:

It's not understanding this that plagues almost all IT projects, causes business to hate the IT dept, and makes IT people generally impossible to work with (I am an IT person).<br /><br />If someone thinks and acts like they are so smart they can do anything, everyone they have to work with will immediately shut down when dealing with them (in addition to thinking they are immature and also knowing that they <i>don't</i> actually know everything).<br /><br />It's not about how much you know, or even how much capacity you have to learn, it's about what you can actually <i>do</i> in the time you have been given.<br />-------<br />I also recently completed a data center move, and I had everything planned out, down to calculating the length of cables needed for each server. This level of planning requires a lot of effort, and even most other people in the business will not understand why you need to go through so much "trouble" to plan so much. I'm happy to say that the only snag I ran into was that the 0U PDUs blocked some of the rack holes, but luckily everything is on Dell rapid/versa rails, which don't need to be screwed in to the racks.orevhttps://www.blogger.com/profile/00246945656519361005noreply@blogger.comtag:blogger.com,1999:blog-3615332969083650973.post-71951726904015972262009-12-22T08:01:30.899-05:002009-12-22T08:01:30.899-05:00Wow, Hugh, great article!

It's amazing the things that pop up. <br /><br />I've been lucky when building out my data sites that I haven't had to migrate them so much as build a new one, get it running, switch over, then tear down the old one. Moving a datacenter as an atomic operation certainly sounds...much less fun. If I ever have to do it, I know who I'm calling :-D <br /><br />The one thing that always caused me the most problems were the leased lines. Getting data lines installed, then the test & turnup, then relying on it, is always hair raising the first half dozen times you do it, particularly if test & turnup needs to happen on a specific day before a specific time. Then you've got to deal with number porting, and hope that goes through. It is certainly a hassle, but when it works, it's beautiful! <br /><br />Thanks again for a great article!Matthttps://www.blogger.com/profile/10471234837140977994noreply@blogger.com
