Unix sysadmin blog: Unixplaza

Unixplaza Blog Site My friend and former collegue Mohamed recently launched a Unix blog: "Unixplaza". Looks like he is writing about his own Unix sysadmin adventures. He really knows his stuff, so that should be cool to watch

When you touch that server you touch me

They turned off the HPSIM and general management and alerting server this morning, or at least, unplugged it, cause it was causing this huge network spike at a remote site I know for a fact that no one besides myself knows what it is exactly that machine does, as its only usefull to me and what I do. That doesnt mean it isnt explained in the server list in Sharepoint that I made and painstakingly try to keep up to date, that no one bothers to ever look at. And of course no one bothered to ask during...

Big Bang Servermove succesfull

This Saterday, we switched the subnet over, and moved all the remain criticle systems over to a new serverroom across the country. I didnt get to make as many pics as I liked, and no video, this was mainly cause I was so bussy of course. :D Half the pics below are curtesy of Arnold. Back of the Digital Alpha box, refernece sho for recabling. Packing up the servers in special locked crates. You could see these movers where the right stuff, big burly guys, but they handled the servers like feathers....

T-Minus 1 day to Big Bang serverroom move

Spent today going over some cabling details mostly. Its strange how stressed we all became over these little details, while we will have larger issues to worry about on the day. (high res) During the move, we will be moving the Voip servers, RF-Controllers (used by various sites to do handheld-scanning), an Authentication server, the Wyse-Terminal (thin client) management server, and 1 PDC. We are also moving 2 very criticle FTP/EDI (Electronic Data Interchange) servers, that handle lots of customer-related...

Version 7.1 of the TCR rack diagram

This is more or less how its gonna be. All the bits are now in place, half the rack stuff has been put in place already, the last stuff goes in coming Vriday. One of the biggest oversights we made was with power requirements. If you want redundant power for a lot of servers, you need to make sure you have a LOT of plugs, enough PDU’s, and plenty of PSU to back it all up. We didnt, partly due to time contraints, budget, but also short-sightedness, and my reliance on people that I, to put it bluntly,...

Computer Room Cleanup and re-cabling Pics and Movies

So a few weeks ago, we spent our Saterday doing major recable work on the new Technical Computer room (TCR) in the new location, in preperation for our Big Bang services move coming up on the 5th of July (it was delayed from the 22nd)) So thise pics and videos are a few weeks old now, but who cares. PICTURES (scroll down for movies) Not enough room to neatly get all the fat KVM cables sorted, so later I actually extended the room for the cables to 2U, and used the cable guide rail only for ethernet...

Desicionmaking on the new Proxy solution

For your enjoyment, here is a, slightly edited, email I just sent to the department head and various other decision makers. It goes over some of the options we need to consider to solve the current issues with our internet access. Names and places have been changed to protect the guilty ;) And please exuse the spelling. I was in a hurry and I really dont care about spelling as much as I do content. ---------------------------- Hi all, We are currently faced with some decisions that need to me made...

Videos of serverrooms and progress report

So I havent posted about our Datacenter move in a while. Well we are starting to pick up the pace now, all the new servers at the new location have been set up, and various other teams are now installing their stuff on there. We are now getting into decomissioning more and more servers from the old server rooms. Here are two videos of rooms as they were 2 weeks ago. Old Datacenter 1 from Robert Kloosterhuis on Vimeo.(I focus on one of the comm pc’s for a while, as the mouse was moving just a minute...
