If I were to build a 2.4 core 2 duo w/ 2gb ram and 4 x 500gb sata and 2 x 160 sata, both in raids. Do you guys think that would be above 2 amps usage? I was thinking maybe the efficient cpu would make up for the large amount of hard drives, all though their IO activity won't be that high. Maybe if someone has a similar setup they could shed me some light .
View 9 RepliesI 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.
I 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?
My 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.
how to go about spec'ing the power consumption of a server. below are the specs of the two servers I'm interested it.
Dual Xenon 2.8Ghz Processors with 2MB cache
1 250Gig SATA Hard Drives
1 500Gig SATA Hard Drive
4 Gigs of Ram
------
Dual Xenon Quad Core 2.66Ghz
1 80Gig Hard Drive
2 320Gig Hard Drives
1 1T Hard Drive
8 Gigs of RAM
you are going to purchase a new rack and the data center offers you a specific amount of power.
you are going to use server's specs like this
Dell PE 1950 III
two processors intel xeon E5410 2.33 GHZ , 24 MB cache, 1333MHz FSB
2x250 sata HDD
8 GB RAM
My question is how many amp's need for one server?
or how much power does one dell PE 1950 III with the previous specs needs?
I'm building a storage server out of spare parts that are lying around here at the office. Purchasing a brandnew server kinda overshoots it's target, since all basic hardware is available lika a big Chieftec 4U casing with 2x 4drive SATA hotswap bays.
The machine will just be dumb storage for saving our backups.
The plan is to add a decent serverboard, proc and some ram as a baseline. On top of that a 3ware 8-port RAID-controller with 8 1TB harddrives (seagate has some nice ones).
Now the only issue i'm having is powerconsumption. The case has an 460W PSU, but I'm not sure if that's enough.
What are the best ways to reduce server power consumption?
I have a Dell Poweredge 860 (2.4ghz QC, 5GB RAM, 2 HDs) and it uses 0.46AMPs when running normally. The problem is at boot up it spikes for a few seconds here and there to about 0.6 and this is a real problem as I only have a 0.5AMP allowance.
Should I underclock it? Remove the CD Drive?
I've received the following offer to dedicated server. I'm planning to use it for small projects to begin with, and expand if potential exists.
That's the reason for my post today, I want to know if the deal presents decent value or not, and what could the server potentially be used for.
Celeron 3.2GHz
1GB Ram
1 X 80GB SATA 7200 HDD (after OS install, leaves about 55GB of usable space)
Direct Admin Control Panel
3Mbps / 3Mbps unmetered line. Roughly 900GB transfer per month.

I have many website projects in mind. Some are more like a hobby, some are business(just for profit). I have lots of free time and I'm willing to work very hard. But the problem is that since I have many projects in mind, it may get a bit messy. I mean I'll get a different domain for all of them but how should I go about choosing hosts? One idea I have is to get one good(big space and high bandwidth) shared web hosting and use it for all of my domains. The advantage is that I'm not exactly sure about how much traffic my domains will get so it seems to make sense to get one big shared account for all of them. But if one of my websites starts getting lots of traffic, can I move it to another host and use the same domain? What would the disadvantages of doing that would be?

Why do these repeat 206 petitions happen?
do 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.

my friend has an un-managed VPS plan in kloxo-hypervm mode
yesterday the stats showed in hypervm as the space was over used, so I personally deleted the processed stats which cleared around 20gb space, again today the space is totally consumed, I don't know why its happening and have no clue where are the other locations where the space could have been consumed i.e similar to location of logs or any other specs which could have been consuming space
unknown space consumption - very high no idea how!
its actually an image hosting site and I noted that not many pics and not much space was consumed in the pics uploaded in the last 24hrs but this really puzzles and troubles me as I am currently tracking my friend's VPS, please help me sort this out problem and keep my head high before my friend

View 10 Replies View RelatedI have a 256 MB VPS. Currently I run BIND to serve a few zones as the primary server and twenty more as the secondary. BIND’s memory footprint is >40 MB which is too much for such low usage. I want to replace BIND with other software to free some memory. Could you please tell me what DNS server has the least memory usage while supporting AXFR? No recursion needed.
What I’ve tried was djbdns. Its zone file format is terrible but perhaps a Web interface such as VegaDNS can help, and TinyDNS does use much less memory than BIND. What else is there?
I 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.
I 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.
how 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

View 14 Replies View RelatedI'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.
We 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.
How 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.
I have been interested in setting up my own server for hosting a website and a small online game I created. My only problem is how good of a server I would need to get.
