Shouting in the Datacenter

[HoID1]

Now i know how to get ping advantage at LAN parties.. ^^

[Shinoter187]

@HoID1 LOL HAHAHA!

[xamanto]

This proves hard drives are operated by little men.

If you shout at them, they get scared a little and stop working for a moment.

[commanderbige]

Anyone who has dealt with IT on a level heavier than a standard user can relate to this!

[RelaxifiedTheSnake]

He's only yelling at it because he's using Windows 98...

[BASGTA]

@RelaxifiedTheSnake That's not even Windows.

[genoem]

@RelaxifiedTheSnake

Naah, that's Solaris.

[DJJussRight]

hmm...i see...i understand some of the words he said.

[Got2flip]

looks like those japanese privately funded water experiment 'research'

[BlasterTon]

FUCK YOU, I WAS ABOUT TO GET A HEADSHOT BEFORE IT LAGGED TWICE!!!

[Eyprethidal]

Anybody ever tell you you sound like Stewie Griffin when you scream?

[Dookiedolf]

I suspect this video is fake.

I say this because the noise he made screaming at the disks is quite common. Im always hearing that noise coming from development teams working on winblows OS and Ive never noticed DASD perfornance issues.

[johnwulgaru]

Yay for Australian accents!



[Redpilldown]

LOL.....I used to shout at my old server when it started its death spiral...RIP

[F0wlPlay]

They're doing their best, yelling at them only stunts their self esteem. Since they think faster, they quickly cope with the depression, but its still not nice to do.

Computers are people, too......kinda...

[DeltaUnifomDeltaEcho]

I think this is doctored. Most cooling systems cause lots of vibrations, and that would increase disk latency then, too. A catastrophe, if true, thinking about the place I work for.

[DJNathanV]

@DeltaUnifomDeltaEcho It's not, this is accurate. A major company I used to be affiliated with tested this also; They put their servers outside in a covered area with NO HVAC and saw better performance and fewer failures.

[Exarian]

you do realize that you have computers that do not like being yelled at, and your yelling at them makes them all stressed and crap.

[youtubasoarus]

So when people scream at their computers, their computers die a little inside. Holy crap!

[Flashcreature24]

UAAAAAAAAAAAAAAAAAAAAAAAAAAAAA­H!

[desnickadoabyss]

why the fuck is selena gomez in the related videos?

[thepumpkin1979]

@desnickadoabyss Selena Gomez got it's own videos probing that her voice with auto-tune don't affect the disks at your datacenter.

[ispshadow]

@desnickadoabyss I'm wondering if it's because both videos were posted the same day? Since Youtube gets so many videos everyday, I'm not sure why the two would be related unless it's also that they were posted very close to each other.

[123DarkAlex]

WARNING: New kind of terrorism!

Al-Caida now starts screaming at U.S. Army Datacenters

Just joking...

[zyzhou]

lol, have 1,000 men shout at your data center

[MrStrangeWill]

@ipavemyownroad It says "521740 microseconds" which is 521 milliseconds. I'm pretty sure Brendan knows how to read output from Analytics (even if you have to wonder why kind of man is yelling at his JBODs).

[topbangshingi]

อย่าแหกปาก เมื่ออยู่ในห้องเซิร์ฟเวอร์

วิศวกรของซันได้ทดลอง "แหกปาก" ใส่แรคเก็บดิสก์ ซึ่งกำลังเขียนข้อมูลอย่างต่อเน­ื่องลงบนดิสก์ด้วย File System แบบ ZFS ผลที่ได้ก็คือเกิด I/O latency ของดิสก์มากขึ้นและมี I/O operation ซึ่งกินเวลามากกว่า 500ms เกิดขึ้นมา และเห็นได้ชัดว่าอัตราการอ่านเข­ียนข้อมูลก็หยุดไปในช่วงที่มีกา­ร "แหกปาก"

[aggressivegamer360]

the 31 dislikes are the servers that were in that room

[Marks256]

Great. Another way for our bosses to tell which employees are disgruntled at work.

"Jim. I've noticed that our disk latency goes up when you're on duty. Do you have an explanation?"

"I HATE MY JOB AND YELL AT THE SERVERS!"

[kght222]

couldn't this be avoided by not having rubber grommets or other noise dampening hardware like that installed with the harddrives. its my understanding that those type of noise dampening systems allow the hdds to move more freely. i mean its pretty obvious (and has been for a very VERY long time) that if a drive is moved while in operation it has to compensate for the movement, and it seems that noise dampening promotes that movement. (btw laptops have allways had bad access speeds while held)

[kght222]

@kght222 and yah i know with ssd that isn't an issue, when i say always i mean for the massive majority of the existence of laptops.

[kebabbert]

It is a Oracle/Sun server, running OpenSolaris - using ZFS and DTrace. It is DTrace that allows him to see disk I/O is affected by sounds. Without DTrace, no such observability. DTrace is unique.

ZFS must use JBOD (no hardware raid card) otherwise ZFS will not function properly. Never ever use hw-raid with ZFS. Read about ZFS on wikipedia for more information.

[TheVigilante2k6]

More likely is the guy pushing his mitts against the drives caused the latency spikes, not him yelling stupidly at them.

[AnswerToNumber]

So... by reducing the surrounding noise they can reduce I/O operations time?

[Darthane]

JBOD, acronym, Just a Bunch of Drives

Typically used when storing huge amounts of data where redundancy and speed are less critical than accessibility.

[Joeaho]

JBot

The act of a male performing oral sex on another man from behind during standard ass play.

[YoYoFlexHUN]

This is a simple microphone.

[d3f4c3d]

good video but .... why in the world jbots, ? really whyyy ?

[eydaimon]

The disk hunter! Forget Steve Irwin, we have a new explorer.

[orbtaybal]

wow thats pretty crazy..This is a very valid reason to actually secure your drives as good as possible. I though a shock absorbtion for the disk to the chassis maybe? I remember reading a MTBF report talking about resonance (exponential vibration).

[MachetePanda]

your not looking at disc vibration! Your looking at a computer sad your yelling at it. :(

[craigcrawford1988]

@MachetePanda You're terrible at using English. Your understanding of "your" and "you're" is horrific.

[MachetePanda]

@craigcrawford1988 hows your understanding of 'you've been trolled sucka!"? bwaahahaaha

[craigcrawford1988]

@MachetePanda Trolling = being an uneducated idiot and then trying to pretend that it was an intentional mistake in order to provoke a response.

You couldn't tell the difference and you were butthurt so you pretended to be "trolling"

[MachetePanda]

@craigcrawford1988 BWWAAHAHAHAAH SUCKA! HAHAHA! PWNED!

[PointsofData]

This is why I gently talk to and praise my computer.

[idiockubaa]

Yeah, I have several datacenters at home.

[JustifyJustin]

Very interesting! What I don't understand though is, surely vibration from the fans/chassis/other blades and other drives would easily create more vibration than voice waves?

Also, does vibration cause only higher latency or total drive failure?

[huboz0r]

Pure geek pr0n...awesome!! :)

[niplok]

What I want to know is what happened that made him scream at them in the first place. :)

[thelightguy1]

Hahah xD! DIE YOU PIECE OF SHIIIIT! How much damage would that cause xD

[ezra4no1]

@tehtrk LOL.. Wow you are pathetic. Did you even read what I posted? Do you know anything about Datacenter Tier standards? If you did, you would of understood why I made the comment about the computer room and the title of the video being called a Datacenter - not a test lab you dirt monkey. Go back to the hole you crawled from and flip your dam burgers - stop pretending like you know what you are talking about - You already made yourself look like an ass from you original comment!

[ezra4no1]

How come everyone who has a coat closet with a handful of "servers" and other network nodes call it a data center? Oh.. because most "IT' personal have never worked in an enterprise environment.

[tehtrk]

@ezra4no1 What's so personal about "IT" anyway? Who said anything about enterprise, though? Also, do your really think that THAT is Sun's Data Center? It looks like a test lab to me. Was your comment only made as an excuse to announce that you once worked in an enterprise environment? I don't think janitorial duties are cause for bragging, no matter where they take place

[LowStuff]

@ezra4no1 Or because a mini is still a car even if it isn't as big as a monster-truck.

[totalgeeta]

but i LIKE shouting at my hard drive :(

[t0mcooze]

This is why you don't use desktop drives in servers/storage. RAID-Duty disks, people!

[MDunka]

I will certainly show this video to my wife! ;)

Lol!

[Yackiass]

Hey, now I know why my Halo DED Server got laggs :D

[LiveVideoBox]

I would like to know how you discovered that. Do you shout at your Discs on your coffee break? Seems an odd thing to discover!

[Jumpinjahosafa]

@LiveVideoBox Maybe something fell and clattered next to it pretty loud, who knows.

[MusicGaming1]

31 people dont understand that disks can be scared...

[paulgear]

31 people must have been shouting at their disks...

[kakureru]

now fart on them and see if they can small it.

(on a side note, operating them upside down will also cause them to slow)

[adj789]

good so my yelling at the computer is now justified 

[copiga]

SO ITS HIM THAT SLOWS MY DOWNLOADS DOWN!!

[TheStigma]

He just scared the shit out of those harddrives! =P

[schadara]

@TheStigma

and me too... I had the volume up and now my sinuses are decongested thanks to this guy.

[weylin6]

They simply refuse to run under that kind of treatment

[jdcrispe95]

how much space you got in all them servers?

[redsquirrelftw]

It would be a bad idea to get Celine Dion to sing near a SAN.

[TheRealFallenDemon]

Have you seen the "specials" programs Brendan uploads to his site? Goddamn they make me laugh every time

[Neslakim]

I hope the angry german kid is watching this...

[Films4You]

nobody likes getting shouted at

[neko9]

lol amazing

[legomaniac150]

One of the SCSI disks failed in my disk array when I tryed this :( Luckly It was in a RAID 1 config :)

[lokrado123]

@legomaniac150

he did say it was not recommended to tyr yourself :p

[svampebob007]

haha the disks got more soul then a ginger XD

[aav1307]

jajaja they are alive, resonance

[HDDvibeguy]

What brand/model of HDDs are in this system?? If they're the kind that have some type of Rotational Vibration FeedForward, my unverified guess (for what it's worth) is that the yell excites the circuit boards of the drives, causes a "false" signal on the feedfwd sensors, increases the track-following error, and results in a reduction in performance.

To test this hypothesis, you could short the sensors on the drives, and see if performance drops when you do your world-famous primal scream...

[roofy2k]

i'm testing this theory...

[meizeepoo]

just wondering...if they made each machine more sound proof, or put each one in a sound proof enclosure so it didn't affect the others....therefore less vibration ...we would all suffer from less latency??

[crack1110]

@meizeepoo when he shouted, the sound was so close that the disk caught the vibrations, but the the cooling of the datacenter is further away so the vibrations won't get to the disks

[MaikUniversum]

Disk gotta soul, dude.

[eMbry00s]

SSSSHHHHH. WE ARE IN SILENT RUNNING HERE.

[g0tcadaver]

STOP YELLING

[wishes1973]

I guess this means no sex in the server room unless you are quiet eh ? :/

[adampd84]

So what were they thinking when they decided to shout at a disk....

[FernDog713]

Thats why when you get BSOD and yell at the box!! It reboots just fine.  Yeah those disks are afraid of getting tossed around!! LOL!!

[crinkleylittlefeloow]

JBOD is "just a bunch of Disks" (FYI)

[quanhn]

fascinating

[superslahbros]

29 people don't get the internets.

[Thevideoclown]

@superslahbros make that 30

[fr3d420]

360p fucking blows.

[res1233]

LOL turn on closed captions, it's funny.

[therealnetgrazer]

@res1233

Just don't look for that dr. Katz!

[SQUIRRELJazz]

@res1233 Wow, that is hilarious.

[Wiejeben]

Go water cooling!

YOUR DISK IS VIBRATING COZ' THEY HAVE FULL OF PORN MOVIES

[kamilm122]

You disk: Shut up or I'll delete ur pornos :D

[januaryjon]

awesome!

[M0rganstudios]

Haha this makes a case for moving music systems to a different room while you work!

[SkuToV]

one has to wonder how you discovered this interesting fact...

[res1233]

@SkuToV Well, here's how these things work. If you have a huge RAID to manage, there's a lot that can go wrong... You get mad, so you yell at your disks, then they, in turn, yell back a big resounding "FUCK YOU". Although, this response is in milliseconds, cause hard drives are just like that. :D

[ROCKNTV1]

@SkuToV you might be surprised what you learn stuck in that room 12/hr a day

[kwagga200]

produKtNZ not too bright. Those Jbods have raid on. Fishworks is a lab for testing the S7000 systems. So no firm. Just R&D buddy. Just R&D

[produKtNZ]

You run Jbod's, so no redundancy then? I'm curious about your firms setup :)

[r8tlsborg9]

That guy better be wearing ear plugs...

[snedie69er]

@r8tlsborg9

You don't really need them unless you are behind the racks or close to the air con

[hyperthreaded]

Hm, maybe one could build a microphone with this. That would be a nice hidden audio channel then. Write a Javascript app that somehow causes constant load on the HDD, then find out what your users yelled when they visited your website :-P

[0nePumpChump]

That is fucking incredible.

[hwangroman]

awesome

[taroliw]

Amazing but fun! Supports my approach of sweet talking to systems I administrate. :D

[jbgandhi2]

@taroliw s/administrate/administer

[redkachina]

I wonder how many decibels is in that room..so loud lol..

[proxicate]

Paper that studies the effect of vibration on hard drives in server chassis, especially 1U chassis sciencelinks(dot)jp/j-east/art­icle/200412/000020041204A04183­04(dot)php

[thelightguy1]

Hahaha! I wonder how they would react with low frequency bass.

[jzaboo1984]

Sometime I would like to do this when my machine doens't work like I want it to ^^

[sirajrizvi]

okay and how we can use this in the real world?

[jbgandhi2]

@sirajrizvi they figured out that vibration reduced disk performance.... in the real world, special disk mounts are being developed to reduce vibration. think of the vibration from the adjacent disks in the array.

[byteusa]

How the hell did you discover this?

[66650043661148305595]

Uuuh, he doesn't shout much louder than the fan noise... Since the fan noise is there all the time, i thought the disks were made to resist vibrations.

[proxicate]

His shouts are vibrating the drives a lot more than the steady hiss of the fans.

[DarkGlaceon]

Don't yell at your computer

[METALIST1989]

Haha, that was awesome! Certainly won't try it, thanks!

[Snipaaz]

poor hard drives

[CarneTiger]

This is what happens to the youtube servers sometimes.

[tutor432]

isolate the HD's in sponge.

[unowiel]

AWESOOOOOOOOOOOOOME

[Dillinger128]

LOL!!!!!.... thats what im gonna go do to our production gear!

[2stepsteve]

That guy needs ear defenders working in a room like that!

[fvlad18]

please don't scream at hdd's again!

or at least don't make a video with it!

[ilupro]

YES HE MEANS JBOD's !!

[Bluezero75]

@ilupro: yeah! and dont shout at your jaybuuuooads either!

[Bluezero75]

don't shout at your jayboads!

[publicpwnership]

I think he said JBOD's

[Bluezero75]

@publicpwnership: ofcourse he did ;)

[reded20]

So no more chanting "COME ON DISK, SERVE THE FILES!! WOOOOOOOOOOOOOOOOOOOOOOOOOOO!!­!" in the server room at work?

[SLRist]

When you think how tight the tolerances are in 3.5" multi-TB disks, it's no surprise that even minor vibrations will have an impact on performance. It's incredible to me that they work at all even with people walking around in the datacenter...

[allanonmage]

This is SPARTA!!

That's what you should have said lmao

[guitodrums]

i play drums near the pc and i see the true... now im removing the drums to see

[marcolovatto]

So what you do mean is that we should concern on making a sound-obsortion project inside datacenters besides the air conditioning stuff???

[HellSpawned25]

This fellow is actually a brilliant orator and author... He gave a wonderful speech about disk latency to our FROSUG (Front Range Open Solaris Users Group) here in Colorado on the 29th....

[TheLightningStalker]

Just imagine what that would do if you're trying to burn a DVD/BluDisc

[netgeek6969]

I think the drive is stopping to say

"You need a breath mint geek" or

"Get out of the computer room and brush your teeth once in a while"

[lkky]

Interesting!

[gabrielbelmont]

you have no right to shout at the disc like that, what the hells wrong with you?

[triforcelink]

SHHHHH! youre scaring the disks!!

[shayslon]

Intersting!

[xrackpro]

Now you see why companies make noise reducing racks LOL

[halvarmagicman]

I have my loudspeakers directly beside my tower, maybe that´s why the harddrives are crossing jordan that often... interresting!

[Svenbertil]

I only thought the vibrations from my disk was disturbing me.

Apparently it's the other way around too.

[Mindraker1]

I always wondered why my computer slowed down while I was masturbating.

[djratboy]

Wow its true. They should put warning signs on porn sites :D

[chillenious]

Nah, that's the bending of the space time continuum when you get close to getting the job done.

[Bratgeraet1]

@Mindraker1 ultra lol:D

[bahaula]

@Mindraker1 God damn, one of the best comments i`ve read so far!

[Deimos69r]

@Mindraker1 your penis screams?

[Dasperix]

@Deimos69r Yours doesn't?

[STEWIEGRlFFIN]

@Mindraker1 REEAAALLLLY??? Maybe you should not eat dog and cat food then, i bet your mom loves seeing that in the basement,you,crouched over her laptop,,fondling your privates to a gay orgy fest of young boys,

[luciasko]

@Mindraker1 You much screaming :D

[medilo06]

what application you are using?

[satelitehacktelmex]

sama !! ::) hehe

[rumarch]

funny guy ;)

[Adrian5606]

well if he got some ssd drives he wouldnt have this problem would he?

I better remeber not to yell madly at my computer for freezing.

[Skumpcake]

For a data farm the amount of I/O operations would top out its rated limit within probably a day, which at that point all that drives and data would likely need replacement.

You also cannot recover data or use in any way a dead SDD. 'Analog' hard drives often can still be made to function long enough even after they're 'dead' to recover data.

[Jinmarui]

I can haz solid state disk.
