It's worse than regular paper IMO. I think it tears more or something like that. I'm pretty much immune to standard business laser printer paper, but a cardboard papercut I know will hurt for days.

Research confirms that black is a color like silver is a color, and that beyond black is clarity.
Years ago my first "real" IT job was as Hardware Support contracted to a major credit card/financial institution. It was an interesting gig and I learned a lot. (And that building is still wired for Token Ring to this day, so giant hilarious TR-to-Ethernet brick adapters are EVERYWHERE under desks, they used to get smashed by feet daily).

I think I still have the little wooden plaque that IBM/Lenovo used to give out to the dudes that got warranty certified for their hardware. Good times, but it got to be a little draining after a while, and this was in the era of IBM/Lenovo ThinkPads that had 7 different screw lengths and replacing a mobo involved removing about 50 screws. No thanks.

I'll never forget the Avaya guy they had insisting that the whole VOIP thing would never take off and traditional telephony would stay king forever. God I miss him.

The worst pain ever!

I dropped a rack-mounted UPS on my big toe. I'm really lucky that didn't break it, it still hurts when I think about it. The server closet was literally a closet. The rack was maybe 6" from the door, which was too narrow to get the rack through. The best part was the UPS they sent required a four-post rack and they had a 2 post. I ended up having to just set it on the bottom of the rack after it snapped the mounts. They had a tower style UPS before that. That is what happens when the people ordering the parts have never seen the client site.

Broke my foot while sitting in front of my computer working. Was sitting with crossed legs, and that somehow cut of the blood supply to my left foot, stood up, and promptly slammed my "sleeping" foot into the ground.

Do a large amount of sysadmins come up from the ranks of DC tech? Seems like most people here have way more experience with server hardware than I do, having come from helpdesk type work, and never having been allowed to touch hardware even once I moved to admin.
In a lot of smaller (<500 employees) companies sysadmin and DC tech is the same role. If you're unlucky you're a one-role shop where you have to do end user support, system administration, project work and DC maintenance at the same time.

I think I've managed to avoid any serious work injury so far. It's mostly been a couple of busted knuckles when installing hardware or getting minor cuts from rough edges on racks. I did fall down a flight of stairs one time, but walked away with just a few bruises.

Eh, besides banging my head a lot under desks I've not had any injuries yet, but I'm sure my time will come.

The last UPS I ordered came in for delivery but it was a tower model instead of the rack mount model I requested, it was a struggle to even flip the box on its side so I left that poo poo at the door for the delivery guy to come pick up again.

Even when the rack model came in I stripped out the parts it was still drat heavy, luckily we've got a platform on wheels I used to scoot it to the cabinet.

Large 3 foot plenum. Many times had to go up into the support beams for the roof because the cable pull got tied up. Foot slips and welp.

Mostly due to stupid and laziness. Don't want to move the ladder and I can probably spider-man it using the steel supports (I couldn't)

There is something from the construction industry climb safety that I learned and applied to crawling around above ceilings: Three points of contact with one grappling (not just contact, but actual holding). This has saved me (and multiple tile installations) so many times that I started teaching it to IT people as core safety.

I recommend it to everyone, even if they are on a ladder: Two feet (not a butt) on the ladder and one hand always holding onto something when working up top.

Before we went to ladders for our cabling, all the wires were stuffed under the raised floor. Not actually better than running wires through a dropped ceiling, but at least there was no fall risk.

It was just endless piles of cat5 because someone used a 200 foot cable to do a 20 foot run. And then that one where someone used a 25 foot cable to make a 20 foot run so there was basically a tightrope wound around the supports. There was at least one rack a ways back that had such a giant coil of cabling below it that it couldn't suck enough cool air and kept overheating the servers. Solution? A box fan. :downs:

There was also the joy of trying to get floor tiles back into their hole without leaving a lip stuck up that people would trip on.

But now we have ladders with cables cut to precise length and it's all done by contractors and life is good.

Apparently I didn't complete my post about almost killing myself with a power supply as a teenager. I blew the PSU because I didn't know that a bigger graphics needs a non-poo poo PSU. I opened it up to see if I could find what was wrong. Then I plugged it back in to see if it had started working. Repeat a few times, and I forgot to unplug it. Thankfully I shocked myself before my hand really got in there, so I yanked it out immediately. Knowing what I do now, maybe God actually does protect fools and children.

QFT, although I learned it from my grandfather for climbing trees. From my experience in construction, though, by the time the electricians get in you have to do gymnastics on top of the ladder to get around all the poo poo that's been put in first. Usually on a too-short ladder because there's poo poo in the way of a properly sized ladder too.

It's your own bloody fault.
I put a server rack in the corner of an used office in an old building.

We had to add extra power sockets, so I got the company electrician to wire in some extra ones. because the wiring was a bit of a mess, we ran a trace on the power to the sockets to find the right breaker for that floor.

Because he was an intelligent sparky, he also tested a socket on the wall to make sure it was isolated before working.

I went to get him a cup of tea and when I came back, he was sitting very still on the desk, looking very shaken up.

Turned out that the wiring for the sockets in the room all ran off the same circuit (as expected).....except one socket adjacent to the one he double-checked. Which ran off the circuit for the room next door for no discernable reason and so was live.

Completely true. The injury a lot of people get from casual datacenter work doesn't manifest for awhile when you realize your hearing is much more shot than it was years ago. Wear the drat earmuffs.

My boss has been bugging me to get rid of the rest of our ten Server 2003 boxes for the past couple months, with several caveats:
Some servers will be replaced at some point in the future, because they're for a product we'll be moving away from at some point in the future. There is no timeline for getting off of this product, and I don't think we've finalized the replacement yet.
Two of the servers will be removed when we move to Office 365 in the next couple of months.
Three of the servers could have been replaced three months ago, but we didn't have storage. We've had a shelf sitting in our office but somehow we never got approved to hooking it up until last week. It didn't actually get hooked up until last night, because the 2U gap in the rack where we were going to install it has power cables running through it, so we had to move another piece of equipment to another rack first.
One of the servers has "a service on it that sends email" and that's all we know about it. My boss decided that he was going to move this service off and then didn't. Today he asks me to take a look at it, and it has its own batch file installer that calls installutil.exe. He got stuck because on Server 2012R2, it threw an error that it couldn't create an entry in the Security Event Viewer. All I had to do was change the batch file to point to the full path for the file that installutil was looking at and it installed. That's all my boss thinks needs to be done, but the config file looks for a local database so I'm just going to install SQL Express and migrate the database over and involve him as little as possible and tell him when it's done.

Jesus i wish people would say what they were doing and why when servers break, I'm lucky if someone even admits to breaking a server, 99% of the time I just stumble on broken poo poo when I'm doing other things, only to find out that it has been broken for days/weeks/months.

We keep our servers pretty well locked down, users can't really break anything except their own software. We just fire up a host, make their accounts, and stay hands off.

But we still get tickets for dumb poo poo, like they gently caress up the config for the software they wrote and come to us expecting help. Or not letting us upgrade to RHEL7 and getting fussy that they're stuck on python 2.6.

As long as they are breaking their dev, stage, or test environments, I want them to break whatever they want.

Now I have a really weird question about some strange behavior; and I might just have my assumptions wrong, so let me lay the whole thing out. If anyone can help me out or provide any other guidance, i'd be very happy.

[root@lgvm100 ~]#

If I have a guest set up for 4 cpu's, 2 cores per socket, the last 2 CPU's ill rarely see any action at all.
I Can run something like:

code:
stress --cpu 4 --timeout 10
and then watch cpu load on only the first 2 processors go up. (cpu 0 and 1 by the os's values)

I can manually set task affinity for stress, and then have it use the last 2 cpu's with something like this:

code:
taskset -c 2,3 stress --cpu 4 --timeout 10 
and it'll use the last 2 cpu's only. (Cpu's 3 and 4 by the OS's values)

task affinity is set everywhere I checked as cpus 0-3

code:
[root@lgvm100 ~]# taskset -c -p 1
pid 1's current affinity list: 0-3
I'm running under the assumption that there should be no difference in having 2 cores vs 1 core per socket where vmware's concerned, but the OS certainly acts differently.
What am I missing? I bet it's hilariously dumb.
