we'll go over some environmental controls. Consider, with I t
00:12
so brown ELTs are when we have a drop in power and blackouts are complete. Loss of power,
00:19
we can protect ourselves with ups is and surge suppressors
00:25
ups is are your best chance to protect yourself from everything?
00:29
Um, so if you're running a server farm
00:33
we're looking at UPS is consider how long you need the equipment to run when power fails, longer needed to run, the more expensive the ups is, and the bigger the ups is gonna be.
00:42
If you're talking about servers, you might want them to be able to run for a longer time, depending on how critically our most of time we're looking at is we want them to run long enough for us to do a clean shut down.
00:53
So the real goal is one. Protect the equipment because power surges or brownouts can damage equipment.
00:59
The new P S will fix us from that. But we also want to have time to do a clean shutdowns that our files don't get corrupted.
01:06
And some ups, they're actually smart enough that they also plug in. So they're providing battery part, but they also have a USB cable that plugs into the computer
01:15
so that when it detects when UPS detects that's lost power, it'll send a signal to the computer telling it to shut down.
01:21
That way, if you're not home or someone's not in the server room and paying attention, the service will shut down
01:27
clean on their own
01:32
dust and a breeze. This a big one, big one. And this isn't even though I've seen I've seen far, far worse than this. But, um,
01:42
you know, it's PC sitting in the back. You know, someone has a desktop PC. For a long time, they've never had that great or anything.
01:48
Um, you go, you go have to work on it for the first time, and it's just full of dust like this. And dust is bad for a lot of reasons. S o what the reason is, well, we have moving parts of a computer. Dust is gonna be bad for moving parts and clog up fans. Clog up the filters,
02:05
clog up any events.
02:07
But the other part of dust is when it sits on devices, it's gonna call his heat. It's gonna cause the device. The heat up more. It's gonna be like an insulate er to those parts.
02:17
So dusting is what cleaning out dust out of your case. And with the number one ways, you can keep your PC running cool
02:27
depending on if you have a lot of If you have pets, you might have a lot more dander and stuff. You might get a lot more kind of a lot more dust type stuff in your computer case, and if that's the case for me, I would have a dog. I have. I'm blowing out my case all the time. So the best way to get rid of, uh, airborne particles. We can have a Rh filters.
02:46
They make filters. You can put on the fans on your computer case
02:51
or filters, you know, in your house for the air in general or your H Vac system in your office or server room.
03:00
My favorite compressed air I buy in bulk from
03:02
from any of the wholesale stores
03:07
love compressed air into everything. Clean my car with it, use it to clean clean computers is the This is the easiest way without even having to take the case off. Sometimes you you can blow out the power supply fans, and you'd be surprised this is really good way to see how much dirt you really have that you can't see so about every couple of weeks,
03:24
in my case, I go and clean out the inside of my computer case.
03:28
Just after a couple weeks. I blow that in there.
03:32
So does, uh, compress. There is really, really good way to do it, but it's also kind of expensive. It's not that great for the environment is composed to a vacuum, which is reusable,
03:45
so they make little
03:46
vacuums designed to the vacuum elope sees. Might want to use him in conjunction. Use the compressed air to get the dust off and then suck it up Real quick.
03:53
Vacuum
03:59
Talk to materials office is typically store chemicals that these were cleaning
04:03
like chlorine and other bad stuff like that. Don't get along with computers or people.
04:12
Follow your material safety data sheet
04:14
for the things most officers should have. Contains vital information for the safe use procedure. The safe. Use an emergency response
04:21
so you know, if these kind of chemical spill you call this number. Call these people.
04:28
This would be usually developed by your company. This is something that you should have to develop yourself.
04:32
Um, maybe really impressed if you had a m s d s for your house than
04:36
you're on top of the game.
04:42
Some environmental controls.
04:45
So h back, we're talking about server rooms. Uh,
04:49
your data centers. We should keep the rounds 30 degrees Fahrenheit.
04:54
Humidity also
04:56
plays the fact you don't want condensation
04:59
when you don't want to be, uh, you don't want too much heat, so
05:02
I d like to be around 40 60. So low humidity get electric static electricity buildup, static electricity. Very bad for computer parts, high humidity. We get the condensation
05:13
water. That's bad.
05:15
Now there's also the hot and cold I'll of philosophy for servers for particularly large server rooms that have rows and rows, Uh,
05:25
where we have 11 row
05:27
of hot air being captured by the vents and the other aisle,
05:31
uh, turning cold air.
05:34
This is only gonna be in your larger data centers. They're hosting a lot of equipment. I mean,
05:40
small office, home office, sit upward.
05:43
This one really apply, But still, and even in a small office home office set up even though we're not talking large h back like this, You know, you should You should consider where you're putting your home server or your regular desktop PCs. It's gonna run more than a couple of PCs in the same room. You want to consider additional cooling in that room or on a C unit in that room
06:03
because they're still just susceptible to heat
06:10
again. When we're looking at data centers, we have environmental model monitoring most, um, do that measure and evaluate the temperature humidity. So if we get above that seven degrees Fahrenheit south and alarm, notify someone's have been coming and fix it, see why, why that's happening. We have too much dust in the air or we detect smoke
06:30
and you're really high end data centers. We get more advanced systems that can detect Ah, you know any chemical or biological type problems in the room
06:40
and really hard core radio logical
06:42
microbiological
06:46
that
06:47
So again, all these all these tools were meant to help protect your I T. Equipment from
06:51
extreme changes in temperature cause
06:55
extremely high is probably worse, but we have low humidity. We can also get
06:59
other problems
07:00
in detecting ah,
07:02
water
07:04
eso fire. Fire suppression.
07:09
You got your basic fire extinguisher
07:12
portable. You can have that in the home office.
07:15
It's ah,
07:15
independent. Doesn't rely on any kind of other infrastructure.
07:19
Could be moved from rooms and then we have fixed distance. They're usually built into the building
07:25
such as water sprinklers, unforced error chemicals.
07:30
Now, these air gonna be really last resort because water can still damage
07:35
computer equipment.
07:40
So to protect ourselves from fire before we have to use one of these
07:44
fire suppression techniques,
07:46
we have smoke detectors, flame detectors and heat detectors
07:53
and some more Ah, available options for fire suppression
07:56
so dry that no water is in the valve until we detect the fire is supposed to a wet one that the pipes actually have water, seeing them at all times.
08:05
So that's gonna give you kind of a time for response. So if the water is not in there yet, that means you're not gonna get water immediately when there's a fire
08:16
avail. Modern take policy violations Take People going to the server room that shouldn't be
08:22
could also be used to see some environmental causes like you might be able to see smoke on a video monitor. See someone pulling a plug?
08:30
So an accessory they're not supposed to.
08:33
I also do after actions. So you see someone? You don't notice someone men, but okay, we have a problem. This computer shut down when it was supposed to go back and look at the video logs to see,
08:45
See if someone was in there that was supposed to be.
