DNS Software With Low Memory Consumption

Apr 19, 2007

I 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?

Power Consumption

Aug 10, 2009

I 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.

Under Consumption Issues W/ A PSU

Jul 27, 2008

Would it be bad to run only 24 hard drives on a 900 watt redundant PSU setup provided in a super micro machine? No motherboard, just the hard drives and backplane? I know that if PSU's aren't loaded enough, they can malfunction or shutdown, as well as encounter efficiency issues. Is there a general rule of thumb for this sort of thing? Should I see if supermicro can give me a lower rated PSU or something? I searched around on the net a bit but couldn't find anything solid for this particular question..

Power Consumption

Apr 22, 2007

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?

Bandwidth Consumption

Apr 10, 2007

I've been having a problem with my webhost (in a shared server), and I don't know if this should be a usual problem or if it is my fault or if it is the host's fault.

The thing is I am getting lots of consecutive petitions for the same files from an IP at a time, which in my logs gets registered like this:

Code:

The thing is I am getting too much bandwidth consumption, and since I've only been with this host for 3 months now, and I never had similar problems before, I was wondering if this problem is something I can do something about? Or is it the host's config?
Why do these repeat 206 petitions happen?

Unknown Space Consumption

Jul 28, 2009

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

Rack Power Consumption In The UK

Feb 23, 2008

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.

Potential Power Consumption...

Jan 18, 2007

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 .

Power Consumption For Dell PE 1950 III

Jun 12, 2008

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?

Building A Storage Server. Power Consumption

Oct 30, 2008

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.

Reducing Server Power Consumption? Underclocking? Ideas?

Feb 16, 2008

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?

Cpanel VPS - Plenty Of Free Memory, But 'committed' Memory Exceeds VPS RAM

Jun 12, 2009

I have a VPS. And have had an issue both when it was 1Gig and now I recently downgraded it to 768m, because I am moving some sites to a dedicated.

However, the part I am having trouble grasping is that when I look at graphs from Munin, it will typically always show 200-400MB free memory (and free -m and top agrees with munin), but Munin shows 'committed' memory that is above the total Ram on the VPS and once the 'committed' ram exceeds the VPS limit, processes start failing.

So, why is 'committed' memory exceeding the RAM on my VPS, when Munin, free -m and top all show there is free memory available?

Code:
root@server [~]# free -m
total used free shared buffers cached
Mem: 768 449 318 0 0 0
-/+ buffers/cache: 449 318
Swap: 0 0 0
Here's a graph that munin produces that shows the 'committed' memory exceeding the total memory.

512MB Memory VPS... Out Of Memory Already

Oct 1, 2009

I have a 512mb DV server with Mediatemple, which I am running 24 (ish) domains off (most of them static websites) and a teamspeak server. I would say MAX theres 10 users online at a time)

Now, I know its running out of memory because i get frequent QoS Alerts in plesk (kmemsize is apparently the memory size):

Oct 01, 2009 11:52:57 AMBlack zonekmemsize

I have attached my results (when I did top).

My questions are:

1. Should I be expecting to be out of memory running what I am?

2. Is there a way to see the problem domains (memory wise)?

3. Are there any ways I can reduce the memory? (I have followed this already:

4. Where is the memory usage coming from (I am finding it very hard to understand TOP)

Xen Using More Memory

Jun 25, 2009

I previuosly have a forum hosted on a VPS with a 512 MB RAM (OpenVZ) and at that time it was only using 300MB of ram during peak time but the server was always down due to harware failures so I move to a new host this time Using Xen with a 768 RAM now it is using all the RAM available which is double the ram that it uses before. Is it really normal for a XEN vps to consume more memory than on a VPS using OpenVZ?

what i dont understand is where did it go. I dont really have much traffic and nothing was uploaded or downloaded. I dont have any automatic backups enabled. How do I get it back to the normal 40%

I do notice i have alot of cpu usage

Which is also confussing to me because I am the only user. I didnt do any backups didnt have any major traffic. And my disk space "memory used" didnt change.

isnt it funny ? 50MB++ left(not yet run anything, no panel running too). is it normal ?

I have other vps running inside virtuozzo, and got 192 MB inside. even its running so many process inside(about 15) that takes about 5-10MB each, its still have more left than XEN.

Xen Using Too Much Memory

Jun 4, 2008

I noticed that, VPS with Xen technology, are using up far more memory than others?

Lets say, I usually use about 300mb of ram in a VPS with openvz, but VPS with xen, with the same usage, is using about 820mb of ram.

Even without running anything...after a fresh install of centos 5, with only few OS processes, its using around 170mb of ram already.

Is this so with Xen? The expected ram usage with Xen? Or am I missing something?
