<0> TenBaseT: that is something I hate.
<1> we've actually got an agreement with HP to not ship us consecutively numbered serials for any given purchase order, to minimize the number that will simultaneously fail.
<2> TenBaseT: Sensible.
<3> smart idea
<2> TenBaseT: It's like RAIDing the batch numbers ;)
<4> Lion-0: will do I'm going there now
<1> kosmo: yeah, there's nothing to **** up your day like powering up a RAID-5 array with 2 dead disks.
<0> TenBaseT: We have a complete data center shutdown this coming easter. I am not so excited about it.
<5> Tron: that's precisely why you need to back up raid arrays. I remember not so long ago having an argument with one of our admins about the necessity of backing up arrays.
<1> oh god, can you keep the platters spinning while it happens?
<0> TenBaseT: *I* will have IBM onsite with spares on hand. I hope the wintel boys have good luck.
<0> TenBaseT: nope. Total power shutdown. we are out of power capacity in the room.
<1> you know, I've gotten into a habit, whenever I order an array I always order 2 more disks than I need to fully populate it.
<0> i.e. we are having new power cut over/installed that day.
<5> kosmo: thy UPS not allow you to shove a generator onto it?
<1> and I keep those extra disks in my desk drawer
<0> whyzzyrd: thats the problem. the UPS is too small.
<5> s/desk drawer/private array/;
<0> whyzzyrd: our 100KVA UPS is running at 99%
<0> whyzzyrd: Easter weekend we get a 225KVA unit.
<1> heh. My 85KVA UPS is running at like 10%
<5> kosmo: ahh. That's difficult, so it is. Can I ask how many racks that's feeding?
<0> whyzzyrd: lots.
<2> whyzzyrd: *nod* Not backing up any data is stupid and insane.
<1> well, there's some data that truly doesnt need to get backed up to tape.
<5> kosmo: 18?
<5> kosmo: 30?
<1> generally speaking any data that users can interact with needs to though.
<0> whyzzyrd: in a way, it is kind of a shame. The data center that we move into 3 years ago was not built with the growth that we experienced in mind.
<2> whyzzyrd: Er, hang on... he was saying "Nah don;t bother with backups"? What about if the raid-5 hardware melted due to a fire? Flood? Hello! Offsite backups!
<0> whyzzyrd: 50?
<1> there are no fault-tolerant safeguards against stupidity.
<5> kosmo: those racks can hardly be full?
<2> TenBaseT: Exactly.
<1> Tron: screw that, what about "$user accidentally deleted it"
<0> whyzzyrd: right now we have 100KVA of power and 30 tons of AC. On Easter Sunday we will have 225KVA and 50 tons
<0> whyzzyrd: you asked about racks.
<5> kosmo: how does 30 tons work out in kw of cooling power?
<0> whyzzyrd: nfi. Im sure google could tell you.
<2> TenBaseT: Indeed, there are lots of ways to have your datacenter ****ed up Real Bad.
<0> whyzzyrd: we have somewhere around 350 server systems in there, plus a full PBX, and 6 racks worth of crisco networking stuff.
<0> whyzzyrd: when our data center was built, the growth trend at the time had our DC lasting for 10 years, not 3.
<5> kosmo: I see.
<5> 1 ton of cooling equals 3510W.
<0> whyzzyrd: we moved in with that 100KVA at about 30%, and we could hang meat in the data center if we wanted to.
<1> hahha my wife just got out of a meetnig with the CEO of HP
<1> swet.
<1> sweet.
<5> kosmo: surely at 99% loaded, you have some issues if a PSU goes bad, and draws $bignum of amps when it fails?
<0> whyzzyrd: no, not really, actually.
<1> slow-blow fuses
<0> whyzzyrd: we had that happen a month or so ago. it just tripped the circuit breaker.
<0> for that circuit.
<1> did it cut power, or go to byp***?
<5> kosmo: last time I had that happen, the breaker went, as did the phase on the UPS.
<0> neither.
<0> the one 20A circuit breaker just tripped. the UPS didnt even "know" about it.
<0> we have isolation transformers between the UPS and the loads
<5> kosmo: what manufacturer of UPS do you use?
<0> Liebert, of course :)
<6> We had a circuit breaker pop here when we had our UPS overloaded with a dozen servers, nothing caught fire. Unfortunately.
<0> I dont know how much overload the lierbert units can take, but they are designed to give full specified runtime at 100% loading.
<0> and, they are supposed to run trouble free at 100% loading.
<5> we've an MGE system just now
<6> Lieberts are good?
<0> our new 225 will have two strings of UPS-300s to give us 15 minutes of runtime at full load
<6> We've just got a bunch of APC units (only recently we upgraded from desktop level to server level units)
<0> its a shame we only really need 8 seconds.
<2> I recently replaced 20 batteries in 2 battery modules for our UPS.
<0> CeruleanD: I wouldnt specify anything else, personally.
<6> ?
<6> What, for fear of ridicule? :-)
<2> It was cheaper to buy the same model of battery that was sitting in the modules than it was to buy a new module.
<0> CeruleanD: uh, superior service.
<6> We still have half a dozen P2-300's in production doing various stuff. :(
<5> kosmo: Ours is specced for 40 minutes.
<5> kosmo: but we have no generation as yet.
<7> all i had to do was 'raidhotadd /dev/md0 /dev/sdb3' and its adding it bacl t the array. wierd it has doen that automatically in the past
<0> whyzzyrd: we only have 15 minutes spec'd in case of generator failure. We seriously only need about 15 seconds of total run time, but it only takes 8 seconds for the generator to transfer
<8> oooo, sweet
<0> siglite: moopage.
<5> kosmo: do you keep the generator spinning, or does that 8 seconds include it starting?
<8> I think I have the powers that be convinced to replace our core switching infrastructure.
<0> siglite: we seriously need to talk business soon
<8> kosmo: moop
<0> whyzzyrd: thats from "cold" start
<8> kosmo: you have my number, right?
<0> siglite: uh, naturally.
<5> siglite: You get the stinking dell switch junked?
<8> call any time.
<0> siglite: next week. we need to make an appointment for actual busines talk.
<0> siglite: foundry?
<8> goin' crisco.
<0> siglite: Im sure youre lovin that. :)
<8> yeah
<8> I like cisco switches and routers.
<0> we do alot of **** with crisco. Ive never heard M complain.
<8> foundry's good stuff too, but I want cisco for this environment.
<0> siglite: oh, dude. Lights is working on foundry's for a livin now.
<8> kosmo: oh yeah? heh, that's cool
<0> siglite: he got a pretty freaking sween promotion.
<5> We have a cisco core, but a lot of our edge is legacy 3com kit.
<8> kosmo: available between 11AM and 330PM monday, not at all tues, and wed. next week is open.
<0> siglite: sent you a meeting invite.
<8> kosmo: cool
<0> siglite: Siegeworks/Checkpoint is under federal investigation.
<8> kosmo: I saw that.
<8> kosmo: and it made me smile
<8> **** YOU MARTY, bwahahahahahah
<1> I thought that was interesting.
<9> kosmo: that was about the federal goverment not trusting the israelis to own something as strategic as snort thoguh, wasn't it?
<1> the investigating checkpont thing.
<1> Dont trust the israelis
<1> they lie cheat and steal to further their own goals.
<1> like all countries do, really.
<10> TenBaseT: actually israelis as a people are quite trustworthy. its their govenrment who are a bunch of evil buggers
<2> DaveHowe: SImilar could be said of most, nay, all goverments really.
<10> Tron: and corporate managements, yes
<11> People in general are not trustworthy (but some are), israeilis are no different. Governments are bastards, israel's is no different.
<1> I dont trust most people either.
<1> paranoia is in my job description
<2> THe majority of people are stupid. The rest taking advantage of that fact are government, crooks (a subcl*** of government), or are frustrated geeks.
<2> Who elects government? The vast majority of people who are stupid.
<12> poof
<11> Tron: sounds about right, although I'm missing the part about pr0n workers ;)
<12> Ahh, my flat is ready.
<3> Eric
<2> Ergo, the vast majority of people get the government they deserve. Because they're stupid.
<12> Sean
<9> Yupp, stupid people elect evil manipulative people for goverment.
<12> Tron, wlf, exel, TBT, DH
<11> ok so riddle me this
<9> unfortunatley there aren't enoguh -good- manipulative people to ballance the equation
<12> sig, kosmo
<2> Nanuq
<9> Eric
<2> wlfshmn: *nod* *nod*
<11> hey nanuq
<12> I should just write a ****ing script to do that
<8> yeah, I'm a cynical bastard.
<12> if $nick = seen_in_last_40_lines then greet += $nick
<2> siglite: WHo the **** are you and why are you talking to me!?!? :P
<11> nanuq too bad backticks don't work with irc clients, or it'd he as simple as `/names`
<8> takes people quite a while to earn my trust, but I tend to be fiercely loyal once they do.
<13> right. All preperations are go. Time for me to relax with a C&C session and then its server maintenance time.
<2> siglite: Aye you're a lot like me.
<12> exel: ah, but in my "list of those I greet" _and_ "seen in the last 40 lines"
<2> Lion-O: Geeeeeeeek! :P
<11> nanuq: fair enough, but once you get to the point that you're automating a social gesture, hasn't it lost all worth?
