<0> but, i'm sure there is a *good* reason why they do it like that :)
<1> i should thank you. this is the first time having any telecom knowledge has been worth anything. :)
<0> hehe
<2> mount -t hfs /dev/hda /cdrom
<2> ?
<1> fredk: http://www.mycableshop.com/300x300/ZPP12E_1.jpg
<0> D-side, basically what I want to accomplish is to have one equipment rack with switches and such in them. then, a patch panel that goes to the different server racks.
<1> that might explain it a little better.
<0> well, several patch panels
<1> so two patch panels (near and far ends) bridging between your equipment. sure, thats standard.
<1> if its only going to be ethernet, you can go with the rj45 termination easily
<3> amazing, I discovered my old Unreal II game.
<0> D-side, it's only ethernet
<1> that might be easiest if you dont have any cabling experience like what i'm talking about, in-house
<0> oh wait, it may actually be serial console too :\ but that should work on the same.
<1> yeah, in that case you can just mangle the cat5 cross connect cable.
<0> D-side, so you *can* buy patch panels with rj45 front and back?
<1> i thought i was going to have to rewire a 50pair 110 today, and i totally wanted to kill myself.
<1> fredk: oh sure, i've seen them, but they're more pricey.
<0> D-side, sure.. but, i'm sure they are more space saving too
<0> APC had panels, but they're **** expensive
<1> oh jeez, they sure are.
<1> god i cant even imagine buying that from them.
<0> 96 PORT, RJ45 TO 110, 568 A & B COLOR CODED, 45 DEGREE ANGLED RJ45
<0> at $1000
<0> haha
<1> fredk: the non-prewired actually save more space, since you're not generally using cat5 cable bundles, and instead have something like a 50pair cat5/6
<1> holy christ.
<1> er. i THOUGHT i've seen them before...
<0> heh
<0> D-side, http://www.lanshack.com/96-Port-Cat-6-Patch-Panel-P2225C57.aspx
<0> what annoys me is the fact that they are 4U (I think)
<1> sorry, was working.
<4> why would you want rj45 in the back, again?
<4> it seems to me that you're attenuating your signal for no good reason
<0> CryptoCat, fair point
<0> I just want something thats quick and easy to work with, ideally :)
<1> CryptoCat: mainly because theres no prior wiring experience inhouse
<4> I mean, the cables inthe back are all custom-length
<0> D-side, there's obviously some. but, no we haven't worked this much with it.
<1> you could just as easily get two 25pin centronics terminated patch panels and cross connect them with
<1> fredk: well no, i wasnt trying to insult you. :)
<0> I know :)
<4> if you have no cable experience it's easier to punch down a color-coded 110 block with a thin screwdriver than it is to crimp 50 rj-45s correctly.
<1> CC here is obviously insulting you however.
<0> we've got plenty rj-45 crimping experience :)
<4> okay, then you're cool.
<1> fredk: pick yourself up a 6 port 110 block and a punchdown tool
<1> REMEMBER to get the 110 blade though, since usually they're just packaged with a 66
<4> the harris 66/110 tool costs more but it will last until you reture
<1> you'll see how damn easy it is.
<4> retire
<1> CryptoCat: 100% correct
<1> chances are you may never need a blade replacement also.
<4> and you may want to take a little fingernail polish from a secretary and paint the edge of the 110 tool that has the cutting blade.
<0> hehe
<4> you'll thank me later.
<1> CryptoCat: thats not a bad idea. i know where you're going with that.
<1> i'm going to try that next time.
<0> I look at some telco installs up at the datacenter we're at.. and, I seriously just shake my head, heh
<1> if you go with a 110 terminated solution, remember you want to get a big *** spool of 25pair cat5
<4> I guess this is how I feel about rj45s in the back of the panel: The wire is permanent wire back there, it goes into the wall.
<1> if you're good, that can span you 12 ports per cable
<0> D-side, sounds sane
<1> CryptoCat: you obviously have a ton of flexibility with punched-in cable
<1> but then, you should really have conduit between panels.
<1> that usually done during construction though i suppose.
<1> oh. haha. i was supposed to call $customer
<0> D-side. i'm looking at APC for racks though
<4> define 'between panels'
<1> CryptoCat: multi-floor spanning segments.
<1> fredk: ew. why?
<4> if it's just switches and panels and no servers in the rack, get hubble relay racks
<0> D-side, who *should* I be looking at?
<1> you're going to pay a huge premium for black steel and red "APC" lettering
<4> a relay rack is a 2 post rack with no enclosure
<0> CryptoCat, I meants for servers now
<4> they're really nice for wire and networks
<4> fredk: HP makes some tolerable stuff.
<1> note we're not even getting into the managed cable equipment yet. :D
<0> D-side, I got pricing for APC @ $800/rack or so.. Which is in my tolerable range.
<4> HP's cheap rack is better than Sun's cheap rack
<4> fredk: does that $800 get you a PDU or side panels?
<0> CryptoCat, no PDU, but yes sidepanels
<1> thats not bad really.
<4> no its not
<1> amazing that APC isnt insisting you use their PDUs though
<4> I just dont want those whores putting a big APCC on the side
<1> CryptoCat: oh dude you KNOW Thats a given
<4> yeah, maybe you can put a SuSE poster on top or something
<1> probably embossed and painted.
<1> i like dell racks a lot.
<4> The one nice thing about suns rack is that it comes with white LED lighting inside
<0> am thinking of using: http://www.apc.com/resource/include/techspec_index.cfm?base_sku=AR2103BLK
<1> CryptoCat: oooh.
<0> D-side, dell racks are only 42U
<4> yeah, I like dell racks too
<0> from what I can tell, the dell racks and the APC i'm looking at is fairly identical
<1> thats not bad looking.
<1> fully populating it?
<1> should i ask what kind of cooling you're using, or ***ume you've got it well in hand? :)
<4> fredk: they're probably built by the same malaysian children
<1> haha
<0> D-side, probably, i'd say waste 4-5 U on stash..and, the rest of servers.
<0> haha
<1> they thrown in a few dozen pairs of sneakers.
<0> D-side, cooling? I don't know, however my datacenter will work with me on that.
<4> I love my lieberts in here but they dont seem to have a good handle on humidity control
<1> fredk: i have to be honest though, lots of no-name racks are just as good
<1> CryptoCat: we just had to pick up an emergency dehumidifier.
<0> D-side, I have a triton rack at my office, which I loathe :P
<1> main AC shat the bed and we brought out the emergency portable
<1> temp fluctuated so hard we didnt count on the humidity. :/
<4> the liebert is chilled water, so as long as I have pressure I'm cold.
<0> D-side, from what I know there is cooling under the dcfloords
<0> floors
<4> but it has a builtin dehumidifier and a evaporator pan with a heatlamp for humidity control, and it swings from 40% up to 80% a few times
<1> oh, raised floors w/ ac?
<0> D-side, yep
<1> and you people dont want a "real" managed cable solution?! :)
<0> water based cooling
<1> fredk: fly CC and i over, we'll do it for a "reasonable" rate
<0> D-side, define #managed_cable_solution :P
<0> hehe
<1> fredk: you really dont want me to do that. :)
<4> I dont have a real managed solution, I just have j-hooks under the floor
<4> but my room is pretty small
<1> excuses excuses
<0> ours will be just 300 sqft or so
<1> i cant really complain. you should see what i haveto deal with.
<0> scaled for about 10 racks I think
<4> I'd like a cable tray though, that would be cool.
<0> however, it's in a larger environment they just subdivide it.
<4> but like I said, the runs are centralized enough to really justify a tray.
<4> arent, I mean
<0> D-side, I do like the 0U mounting of PDU on APC
<0> D-side, plus they seem to have solutions to manage your cables
<1> fredk: thats fairly standard though, most racks will have mounting brackets at the rear of the cage
<1> *i think*
<0> D-side, the work one dont
<0> but thats **** :)
<1> good thing i covered my bases with the "i think" then. heh
<0> hehe
<1> you're obviously competent enough to make this a non-**** solution, no matter what you do. dont worry.
<0> I *try*
<1> when it comes to managed cabling and racks, i really strive for perfection. i'm just an ***hole about it. :)
<0> I do too, cause I know what a cable mess looks like in a rack with 30 servers
<1> haha
<0> and I know from experience how it can lead to stupid downtime.
<1> imagine non-19" racks, just stuff you'd pile boxes onto like at a supermarket.
<0> ****** that cable fell out without me knowing it
