VPS For Non-profit Organization
Aug 10, 2008From reading these forums I have learned alot about many of the hosting companies, but I would like for you guys to weigh in specifically for my situation.
I am Chairman of a non-profit organization (we are a federally recognized 501(c)3 non profit) that will have an internet radio station. We will have 300 or more listeners and so the bandwidth will be tremendous. We will be streaming at 128/kbps and of course a shared hosting environment would not work. Therefore, I am looking at a VPS but price is an issue. I realize that it will not be cheap but I want to find the best deal and the best quality around. With that being said, I realize that I can't find both in one VPS so I am looking for a balance between quality and price. I have read about problems with HostV (not to pick on them) and other companies but their price is good. I just don't know if the price is worth the hassle because this station needs to stay running.
We will be streaming the signal to the VPS from our servers and we will use Shoutcast (we might use icecast but shoutcast looks like the one right now) to broadcast the signal. Our site will be hosted elsewhere so our main use of this server will be the broadcast. I would love any suggestions, thoughts or recommendations for our situation.
BTW, I am not writing this to solicit offers for donations. I am seriously wanting to know what is the best solution for our situation.
TrippLite Racks
Nov 5, 2009I've been quite happy with the TrippLite equipment we've used in the past and I'm looking for good quality, reasonably priced racks to use in our commodity DC. One interesting one I came across was being sold by Dell alongside the Dell PowerEdge 4210 we use for the main USSHC DC - the TrippLite SR42UBEXP.
If anyone has any hands on experience with TrippLites racks/cabinets I'd be interested in hearing about it. I'm very happy with the PowerEdge racks but since I can find the TrippLites, which appear to be very comparable in design, for about 1/2 the price I'd be willing to consider them.
NEBS Racks
May 19, 2008Does anyone know a good source to buy NEBS certified racks from? They must be NEBS certified as they are going in a central office that requires all equipment (including racks) to be NEBS certified.

View 6 Replies View RelatedPower Supplies: Do Redundant Supplies Use More Power Than A Single Supply
Jul 27, 2009do dual power supplies use more power than a single supply?
E.g. Say I have a server than uses two amps, powered by a single power supply. Now if I switch to a dual supply (and say each supply has the same efficiency rating as the single), does my server use more power? How much more?
My simple view of this is that it probably does, but maybe not much. The second power supply consumes some power itself, but since its not under load, it doesn't consume much. Therefore, my server with redundant supplies might use 2.1A or 2.2A.
List Of Dedicated Providers With Private Or Virtual Private Racks
Sep 4, 2008I am currently with the planet and am happy with them, however as part of a new venture I need to gather a list of hosts as well as the planet that will be able to cater to the ventures needs and go to tender with the requirements.
ThePlanet offer something called a virtual rack. This is cheaper than renting a dedicated rack, allows for Gb networking but doesnt not allow for a SAN. Do other providers offer something similar? The cost of putting a machine on the virtual rack is not that much more expensive than just renting the machine. I guess there isn't too much to these set-ups to be fair.
If not, then we are looking for dedicated racks, with the ability to host a SAN at some point, but starting off with say 3 servers (2 web servers, 1 storage server with raid5 6Tb of hdd). These servers will be dealing with network cameras although I don't think that many will be streaming at once but the network capacity does need to be there.
Who's door should I be knocking on to find out some prices?
One final thing, should I bother looking for co-lo providers as well? We are in the Uk but not precious about our host being in the same country at all (it would be nice but uk prices are ££). Really, all we would be able to do with co-lo is buy the hardware outright to save price as we are not interested in looking after the hardware.
Power
Dec 2, 2007I just signed my agreement for 2 cabinets at Internap's Atlanta CoLo. For now, I will just have 1 120V 20A circuit in each cabinet.
At my office's server room we currently have 8 circuits I am powering my 2 racks from. I am just curious how many servers you can typically put on a 20A circuit. I am also considering adding two additional power feeds (1 more for each cabinet) to have truly redundant power for my dual power supplies.
I am hoping that 20A is plenty for my needs. I have around 20 HP and Dell systems. Mostly HP DL380s and Dell PE2950s.
Any ideas? I am splitting them in half, only filling up a half of each cabinet for now, as we are growing quickly and I wanted to overguy space so I would not be forced to add another cabinet later and have it end up somewhere else in the DC.
Power Metering
Sep 10, 2009I wonder if any colocation providers here have any tips for measuring power. Currently I'm using APC 7900 power strips with amperage meter. I'm not a power expert by any means but I want to be able to calculate whats the cost having a server drawing 2 amps 24/7 365 days week.
Our secondary site gave us a whopping power bill, and at our own data center we never considered charging our customers for power.
Power Consumption
Aug 10, 2009I need to know what happens when a rack has capped its (lets say) 5A limit. I'm trying to calculate what exactly I can put into a rack and am considering that not all servers are going to be 100% load, as that would be bad performance anyway.
I guess it could do the following (but really don't know):
Cap performance of all servers
Cause system failures
Trip
The rack would have servers, a switch and perhaps a Remote Power Strip and Firewall. I don't know how they would be affected.
Power Estimate
Apr 8, 2008how much power the average hard drive would use? (ie a 1tb drive). I was looking on WDC's website and it said 7.5 watts peak durring writing and reading etc, so assuming thats at 110 voltage, would it be safe to assume that 12 drives @ 7.5 watts each would make a total of .81 amps? I am going off of the equation that Amps = Watts/Volts. So amps = 90/110

Feb 4, 2008I've been doing research, and looking around on Google for a list of processors that use little power.
What are some of the processors out now a days that have minimal power usage?
Chassis will be SuperMicro's with 1-4 GB ram, if that's of any use.
Colocation Power
Jan 13, 2008We are transitioning from an on-site data center to a collocation facility and are having problems negotiating the right amount of power, the type of connections, and the PDU power strips that we need.
For simplicity lets say that we are going to rent a 10 ft by 10 ft cage area. This should house 4-5 rack cabinets.
The amount of power we are given for this area varies with the lowest being 120 watts/sq. ft and the highest being 175 watts/sq. ft.
With 120 watts per square foot that comes out to about 6.25 circuits that are 20 amps for a 10x10 space.
For the initial setup we would have a Cisco 73xx Router, a HP 26xx switch, an Avocent IP KVM, an EMC CX3-10 SAN, and our Dell PowerEdge 2950 III servers (4).
Using the calculator at: dell.com/calc I show the power requirements for all of the Dell equipment to be:
C13 Power Cord Qty: 12
Amperage on C13 Cords: 26.49 amps
System Heat/Power: 2754.6 watts
Total Current: 13.24 amps
The way I was envisioning this was Rack 1: Router, Switching, KVM on a 20 amp circuit and Rack 2: Dell Equipment on a 30 amp circuit. Is that right?
Additionally, I'm confused about single phase vs. three phase power in the data center and what most people choose to implement. I've heard talk of getting redundant power in each cabinet but that seems like you limit yourself to half of your space doing it that way.
And the last thing is it's confusing about what type of PDU you need to put in your racks to make it all come together. All of our equipment should be using IEC C13 cords and we're thinking about going with Avocent for all of the KVM/PDU so we can centrally manage it.
It seems to me that if the cost is roughly the same we should be pressing as hard as possible for the highest watts/square foot since that seems to be one of the most important commodities in any data center.
Power Requirements
Feb 16, 2008How much does a typical quad core Xeon eat, say an E5410 or a E7320? a 2GB RAM stick? A 500-750GB SATA disk? How much is the system overhead for a 1U unit? I tried to find data on this without too much success. For example Intel says the same number (80W) for an 1.6GHz CPU and a 2.4GHz one -- that does not sound too reliable to me.
If this is too abstract, then I would like to ask aobut the real world power consumption of two boxes. 1 E5410, 8GB of RAM, 2 SATA disk maybe 10K RPM. The other will have two E7320, 24-32GB of RAM and 3 10-15K disk.

May 4, 2007how to figure out how much power one would need?
My potential colo provider is saying that a 5A circuit comes standard with a 1/4 cabinet and that they charge $20 per amp over that. I will have (6) Dell 1650's with dual 650W PSU's. Any idea how to calculate how much actual power I will need for this configuration?
Power Usage
Mar 9, 2007Im currently going through my tool box of parts and was thinking of building some cheap dedis for my customers. Unfortuantly the only hardware I can find is SocketA AMD 3200 (Barton Core) processors but Im unsure of the power they pull in amps.
The setup I would be looking to us is 512mb RAM, 80gb Hard Drive, Socket A 3200 XP processor.
Power Pricing
Dec 13, 2007What do you think the Standard Pricing for power should be in Toronto.
I heard $10 /amp how does that sound, Im just doing some research thanks for your comments.
IBM Bladecenter Power
Oct 29, 2007I'm working out the power needs for running two Bc's ( each with 10 blades @ dual 2.8 with dual ide disks, 2x mgmt & 2x 4port Cisco sw ) and am quite frankly going in circles!
The rack will also host a 3550 swith, Vyatta fw ( dl360 ) and a TFT slide out job.
Now using the IBM calc i'm getting figures of around 20amps? Which sounds fair enough for 20servers, but is this correct and would have been better off with a mix of 1u's and 2u's?
Seems the cost saving on the blades will be outdone on the power consumption.. if so that's the last time i watch an IBM tv add!
Was Some One Stealing My Power
Aug 26, 2007I have just removed my servers and switch from a data centre in london only to find that for the last 6 months since I last visited the data centre some one has had one of there switches plugged into my power strip. When I approached the provider about this they claimed it would have not affected my charges for power consumption because they were monitoring the power of each server.
Is this possible for a provider to monitor the power for each single server on a power strip that I own? or are they just trying to get them selves out of trouble for the fact they have been over charging me for power for the last 6 months?
Power Consumption
Apr 22, 2007I maybe interested in co-locating a server but looking from the power max for a 1U server of around 0.3Amps I'm wondering if it will be easy.
Doing the equation 0.3 * 240 gives me 72watts I believe. (Where 240 is the voltage for the UK). So with this, it doesn't give me much choice considering most processors run around 90watts and that doesn't leave any room for the power from hard drives and memory. Does anyone know what the average power consumption is for hard drives and memory?
I'm not looking for a really power system, but I would like something that if I pull it out of co-location that I can still use it one way or another. So was looking at an AMD Athlon 64 X2 where there is a 34watt version that is seemingly discontinued. Or use an AMD Turion X2, which are again hard to find, with a mini-itx board. Running with the mini-itx board, there is also the Intel Core 2 Duo which I can get quite easily.
Does anyone else co-locate and how to you manage the specification?
Low Power Dedis
May 29, 2007at building 10 new servers to sell to our customers as dedis but are I am unsure of how power hungry the processors are.
The two options I am looking at are:
# E6600/E6400 Core2Duo Processor
# AMD X2 Energy Efficant 5000/4800/4600 Range
All the same setups are using just the one harddrive (SATA2 80gb) with 1GB RAM all on a budget motherboard. While I have seen Heavily used Core2Duo systems pull over 0.7amps (with 4gb ram and 2 hard drives) I am unsure which processor setup will use the less ampage. We are running these at 230v so had anyone got any ideas how much ampage these may pull and which would use the least ammount of power?
Are Power Generators Really Up The Task
Jul 16, 2009Recently Rackspace experienced an outage caused by their generators. I would not open this if its wasnt because in the last 10 years everytime there is a power outage on a DC the generators failed. (this is not a rackspace post, i just took 1 of 100 examples)
I dont want to mention names but I have seen plenty of DCs on which generators fail when the task is loaded to them. Some people said its because the maintaince is expensive and they dont do it on time.
Thats not always the case as I have seen DCs which made their maintainces on shape and time and they also had problems.
Now my question is if putting up generators costs so much money and we see them fail over and over again, are they up the task and worth the investment?
We know network only needs a short time without power and all is lost. This topic is ratter an approach on how to best handle power loads. Im sure there must be some way to actually be sure that when power FAILS, generators will keep up the task. The most sure testing would be to actually shift load to the generators every some months to test them but that would be plain Crazy on a production datacenter. I see that most outages have always the same guilty gear, generators...
Lets take another example, Gmail recently failed big time, because some Google DCs dont have chillers to keep the DC from getting hot (New Europe DC) for example. On hot days they shift the load to other DCs and turn the DC off. That of course failed too on a real scenario. Now Google is not a standard DC, but if they keep such a risky scenario in place they must have a sure way that power will keep up when the load is shifted and there is a big peak.
Will there be a better solution in the next 10 years for power or are we going to keep hoping generators dont fail exactly when we need them the most. Maybe we all should have UPS (plenty)on a rack to keep the power until the DC brings up generators, but thats useless if the network is affected as well and it always is.

Aug 25, 2009I recently bought a 2nd hand HP/Compaq ProLiant DL360 G3.
I've been checking some places to co-locate, rapidswitch & racksrv both look good but I'm still trying to figure out how much my peak power usage is during start up.
I've been googling to try and find out how, but I have had no luck.
So basically, my question is, How can I measure the peak power usage(in amps) during start up?
Sorry if this has already been asked(I did do a search but didn't find anything relevent).
the specs are:

Rack Power Consumption In The UK
Feb 23, 2008My nearest major city is Manchester, so naturally I'm looking for rackspace in the region.
Unless anyone has better suggestions, I'm thinking of going with NorthernColo. They start at £50/month but jump to £70/month if you draw more than 1A of current.
If my basic physics is anything to go by, 0.5A at our 240V means a maximum server power rating of 120 watts.
...are there any dual-core / 2GB RAM box configurations which consume less than 300W thesedays? My own USB mouse for my laptop consumes 50mA.
Otherwise I'm begining to think of their 0.5A pricing as being a bit of a scam, since the 1A price also pays for 2U worth of space.
