toddfreading scrollback and commenting out of context is fun sometimes heh
'wondering what it'd take to receive zfs incrementals' I'd love to just store the compressed incrementals rather than have a system that does zfs natively heh, zfs is good and all but gpl infested is not exactly the bsd cup of tea ;-)

up_the_ironsjlgaddis: yeah, and 80% of looking glasses are slow and suck
jlgaddis: i would much rather use a route server
telnet route-server.ip.att.net, for example
or router-server.he.net 		[11:01]
jlgaddisjlgaddis nods
i tend to use route server and looking glass interchangably 		[11:02]

d^_^bup_the_irons: you around? [17:43]
ballen_Up_the_irons: suggestion on PDU, any reason to have a network accessible one? [17:43]
up_the_ironsballen_: I pretty much use AP7930 and AP7932 exclusively [17:44]
ballen_why'd you need switched PDUs? [17:45]
up_the_ironsballen_: so i can power cycle stuff remotely [17:45]
ballen_hmm, hace remove mgmt cards for that
have* 		[17:45]
up_the_ironshuh [17:45]
d^_^bup_the_irons: I am (dj_goku) I was just updating my card information since the old one wasn't working or so I thought it wasn't. [17:46]
ballen_you power cycle boxes
to*
I have remove mgmt cards in my boxes
which will live on if the system is down 		[17:46]
up_the_ironsd^_^b: oh ok, you went through the regular form (picked a plan, etc...). Just card updates don't require that (link in email wouldn't have asked for it)
d^_^b: thanks for clarifying 		[17:46]
ballen_up_the_irons, also why'd you go with 120V pdus [17:47]
***ballen has quit IRC (Nick collision from services.)
ballen_ is now known as ballen 		[17:47]
up_the_ironsballen_: right, but i can't always be sure every box has remote management capabilities. What if I need to power cycle a security camera? A Cisco that has locked up? etc.... none have power control [17:48]
ballenah
yea don't have much of that issue 		[17:49]
up_the_ironsballen: 120V PDUs because it is too difficult to find gear in all 208V [17:49]
ballennahh I have all 208
or you mean like network, camera, etc gear? 		[17:49]
up_the_ironsballen: in your scenario, i believe you already _know_ what will go in your cab, I can't always be sure. hence remote power PDUs [17:49]
ballenk
just trying to figure out how people actually use switched PDU's mainly 		[17:50]
up_the_ironsby and far, most equipment provide no remote power capabilities [17:50]
ballenand see if it fits any use cases
yea
minus a few switches, and old hardware all my boxes can be power cycled
do you use a step down transformer or a 120V UPS? 		[17:50]
up_the_ironsballen: imagine if your remote management card (in my case, SuperMicro IPMI 2.0) fails. What do you do? You can't do squat if you rely on it alone. With switched PDUs, you can at least "fallback" to the older method of power cycling the actual port [17:52]
ballenyea, doubt it worth the extra cost though
at least for me
and who wants to figure out this question...
currently have a 5000VA UPS
208V
a step down transformer to 120V
4 Dell R900 servers
at 4 bars of utilization on the UPS
would moving to using a PDU and running the servers at 208V lower the UPS utilization 		[17:52]
up_the_ironsballen: it is certainly worth it for me. Imagine if the box which hosts your VPS had some failure requiring a power cycle. I could either 1) power cycle it w/ AP7932 in 30 seconds, or 2) power cycle it in the time it takes someone to physically be there (usually an hour) ? To me, that cost is HUUUUUUUUUUGE in terms of downtime. Yes, please, ram me in the butt with the $700 one time fee it
costs to buy an AP7932 ;) 		[17:55]
ballenlol
right on
yea if something goes down off hours for me
someone looses the time I takes me to get there on computing some bio calculation
but they can be restarted 		[17:55]
up_the_ironsyeah, downtime simply costs less for you [17:56]
ballenyep [17:56]
up_the_ironsi'll gladly hit the Nagios "Acknowledge" button on a non-critical host that is down at 2AM and back to sleep too... ;)
*and go
but for those hosts, heh, why even get a page
an email is fine and i don't worry about it 		[17:57]
ballenyea [17:58]
up_the_ironsnow i'll try to figure out your power question [17:58]
ballencool thanks
if you need the specs on the Dell's let me know 		[17:58]
up_the_ironsi do
how many bars is 100% utilization? 		[17:59]
ballen5 [17:59]
up_the_ironsnow here's a question, Mr. I Have Everything in 208V
why didn't you just go DC power all the way? would save 20% 		[18:00]
ballendidn't buy the hardware... walked in with it sitting in boxes [18:01]
up_the_ironsballen: generally, if you _can_ run your gear at higher voltage and you have the infrastructure for it, then do it [18:01]
ballenright [18:01]
up_the_ironsdon't step it down [18:01]
ballenyep
I know
again... wasn't around when the hardware was bought
trying to fix things 		[18:01]
up_the_ironsi think your UPS would be a little less utilized, yes, if you switch to 208V [18:02]
ballenhmm
justifying the 180 bucks for a PDU and lossing 500ish for the wasted cost the transformer
? 		[18:02]
up_the_ironsjust looked up the R900
so wow, you have 4 of these at it is basically using 80% of your 5000VA UPS? 		[18:03]
ballenyep
well looking at the APC manual 		[18:04]
up_the_ironswhat's in it, a jet engine? [18:04]
ballen4 bars = 67%
5 bars = 84%
3 = 50
yea I know
thats why I'm trying to figure out whats up with it 		[18:04]
d^_^bup_the_irons: so is my second card working? [18:06]
ballenwas actually hoping to plug in a single PSU from each of my two M4000's into it [18:06]
up_the_ironsd^_^b: haven't tried yet
ballen: well, it says:
1030 W (90V - 180 VAC) - 1570W (180 - 240 VAC) hot-plug auto-sensing redundant power (1+1) 		[18:11]
jeevhey
grub is gay 		[18:11]
up_the_ironsballen: so it is kinda on the mark
ballen: they are simply energy hogs 		[18:11]
jeevup_the_irons
when are you gonna have ssd vps 		[18:12]
up_the_ironsjeev: when someone wants to pay for it [18:13]
jeevhmm
you can charge double for space and try it as a beta
have you calculated how much expense the drives would add ? 		[18:14]
up_the_ironsit would be WAY more than double
have you seen SSD pricing? :) 		[18:14]
jeevbut doesn't it save a lot of power ? [18:14]
up_the_ironsit wouldn't be substantial enough
my boxes take 2A
if it dropped down to 1A
1A is not a lot of savings in terms of raw cost 		[18:15]
jeevit's like 5 bux a month lol [18:15]
up_the_ironswith power conditioning cost, more like between $10 - $20 per month [18:16]
jeevoh
not bad
if you have like 5 boxes, that's like 50-100/month
easy enough to just charge double for spacing and make your money back within a few months, no ?
how many drives does it take to complete your aray ?
array 		[18:17]
up_the_ironsjeev: huh? what about the actually SSD cost. WAY f*cking higher than a SATA drive and MUCH lower capacity
jeev: 8 drives
jeev: buy me 8 500GB SSD's and I'll offer SSD VMs ;)
[18:19]
jeevjust use the 160gig ones
why 8
fuck it they dont last long anyway 		[18:21]
up_the_ironsjeev: performance [18:23]
jeevraid1 for life! [18:23]
up_the_irons8 drives in a RAID 10 @ 7200 RPM really makes a difference [18:23]
jlgaddisheh, i use raid0 at home [18:24]
jeevraid0 sucks!
i love raid -3
anyway, you dont know anything about anything if you dont use AP9606's 		[18:24]
jlgaddisyeah, discontinued cards are ftw [18:32]
up_the_ironsi'm installing a new AP7932 tonight actually... moar powar! [18:33]
