Ask Slashdot: Server Room Toolbox?
jandersen writes "I am the system manager in charge of a smallish server room (~50 servers, most in racks), and I am going to buy a set of tools; but first I want to hear what other people think would be a good idea. Certainly a range of good quality screwdrivers — slotted, Phillips, Pozidriv, Torx. But what else? Tape measure? Spirit level (for aligning the racks)? Any meters or cable testers? A wood lathe? I can probably get away with a budget of a few hundred GBP, but there ought to be some mileage in that."
All your good tools will be stolen, just buy the cheap stuff so noone wants to takem. Its better to have cheap tools then none at all. (Or you could nuy nice ones and lock them up and then pray you NEVER leave the tools box unlocked)
The dust thrown out by the wood lathe is a good idea for ensuring a constant turnover of hardware in your server room, but I find that dust that is conductive works even better, so I'd recommend an angle grinder over a wood lathe.
always prove useful. And some ammo.
Don't forget:
- a rubber hammer (for failing hard drives without visible traces)
- a cattle prod (for failing "visitors" without visible traces)
- a sledgehammer (for failing anything if you don't mind visible traces)
- thermite (to get rid of visible traces)
I gave up sigs almost a year ago.
A toner that works on live network cables
a cable qualifier
a fluke nettool or equivalent
A set of loopbacks
a set of console cables
a buttset
A cage nut tool
2 sets of screwdrivers, including torx, hex, etc.
telescoping magnet (part retriever)
Box cutter
work gloves
flashlights
ear plugs
a jacket
scissors
pliers
crimpers
a jackrapid if your patch panels are modular
a crashcart
power screwdriver
a cordless drill
a rack lift
velcro spools
a stockpile of cage nuts and (matching) bolts
The first few on that list will break the bank.
Most of the time, all I really need is a screwdriver with bitset, a leatherman wave with bitset, a cagenut tool, a flashlight, and a console cable.
Because sometimes you want to test the wires that are not connected to a server/workstation.
Get a good hand-held time domain reflectometer. I prefer Fluke but I'm sure that others are just as good.
This will not only tell you that the wires are correct, but if they are broken it will tell you how far away they are broken. VERY handy for hunting down problems.
It all depends on how big your server room is, how actively it changes equipment, and a number of other things.
For a few hundred (anything), you're not really looking at much of a tool set. There are some 'bare minimums', and 200-300 will be eaten up in very short order. Here's a list of what I consider to be bare essentials:
* A multi-set of philips, flathead, etc. screwdriver bits. Make that two sets, they're cheap. Pick up an extra multipack of #2 and #3 Philips driver bits for another couple bucks. Forget independent screwdrivers, that's just wasteful, and you'll never find the one you want because it's awkward to keep them all together and sort through them. In all likelihood, you'll need #3 and #2 philips only, as more and more systems come toolless; this would be for rack equipment.
* A manual torque driver is a must (batteries can fail) - don't be that guy who over-tightens everything and it's impossible to get crap out of a rack without shearing screw heads and stripping bits. You can pick up some pretty decent ones for $10-15. I like the ones with the recessed rear caps which have a cylinder full of different bits.
* A good multitool. MUST MUST MUST. SOG are awesome, I love my PowerAssist. I have done emergency recabling jobs with nothing more than a Spartan Swiss Army Knife. Currently, I'm liking my Gerber Balance (and I keep extra bits in my pocket, just in case). This is your tool; it goes in your pocket, and it's your last line of defense against not being able to fix something because someone ran off with the tool you need.
* A good flashlight. I'm not talking about a $120 surefire, a cheap $10 Trustfire from DX or the like will do just fine. It just can't be crap. (Personally, this is something I always keep on my person anyway.)
* cable tie offs, velcro, cat6 jack heads, spare power and ethernet cables,, etc. - you'll want a supply, because you will probably need them.
* RJ punch down tool (to crimp onto your cat6) - the alternative is to buy all pre-cut lengths, and this makes a mess in short order while wasting a fair amount of money.
* A network continuity testing tool, preferably one that'll allow you to test things thoroughly and not just give you a 'good' light.
* A hardware ethernet tap. You can get a good one for $15 or so.
* compact cordless Makita torque/impact driver, preverably the one with the pivoting head. I have spent a lot of time rebuilding etc. racks, and you never know when you'll need
A very nice to have: compact cordless Makita torque/impact driver, preverably the one with the pivoting head. I have spent a lot of time rebuilding etc. racks, and you never know when you'll need it. IMO a 'must have' but only because I've redone entirely too many racks manually.
This list can balloon quickly, depending on how reliant you are on vendors, and how

Seriously. Hang a thermometer a foot or two (okay, 30 or 60 centimeters) from the center of the ceiling. Keep an eye on the little guy. Compare it to the thermostat's reading. The "real air" temperature in the room can often be much different than the temperature on the where the thermostat is attached, _especially_ if it's an exterior wall that's being pummeled by sunshine or winds.
I've seen places where the temperature fluctuated so wildly as day and night cycled that it screwed with the equipment, Every time you have a failure document what kind, the thermostat temp and the thermometer temp. If you spot a pattern you might consider calling in the HVAC guys for a recommendation.
This is the dumbest question posted here (in a long time).
You may well be right. However, the stupidest question is always the one that isn't asked.
Because right now you sound like a complete ignorant who don't even know what a server is.
And you sound like somebody who feels the urge to put somebody down because it makes you feel a bit less bad about yourself. Alas, it didn't work - I don't really give a toss about what you say; if you believed in yourself, then you wouldn't be afraid of asking, even if it makes you look less than divine.
And if you look around at the answers I've got, you will see that a number of people have given some very good advice. Some of it I already know, but there are some good, new ideas that I hadn't thought of.
You lose a man point for even asking that.
Man points? Who cares about man points? A real man is not afraid of looking stupid, if he needs to learn. The only stupid question is the one you don't dare to ask.
You listed a lathe on a budget of a few hundred GBP?
That one was a joke - it's something we are prone to in UK, sorry.
I thought of suggesting a scythe, but that sounded kind of rural, so ..., well you know how it is.
