We are about to install 4 Compaq Proliant DL360 servers and a small Linsys switch into a data centre but I have no idea how many amps a small setup like this is going use? What kinda power does a server generally use and is there a way to keep the power it pulls to a minimum.

How many Amps should this server use, in a 220V circuit?
if any of you know the charging amps of a smart ups 3000 or 2200(I cant find it on the apc site)?... I'm thinking to use it to charge a 48v golf cart... anything bad about doing this?.. I'm thinking the golf cart batteries are too large and may take a couple days to charge with the ups...
View 4 Replies View RelatedWhat do you guys think about putting 40 Amps into one rack? Our colocation provider wants to whine about it and not allow it. When we're paying them $1000+ a month - I think this is just shoddy. They say it's for heat concerns - but really this just makes me mad. We have fifteen 1U servers in there, and can't get much more on our existing 20 amps.

Ive been on the dell calc and they dont even have the processor that im after in their calc for me to get a bearing... even then i couldnt trust it.
Here is the actuall link to the server im talking about.

I have always found this odd and do not understand enough to figure it out.
Any knowledgeable people would be cool.
My datacenter has given me 2amp circuit for my computer. It seems to run fine on it.
Looking at the back of my power supply it says the following
520Watt max
Input rating
100-240v~,50-60Hz
7A-3A
Output rating
+3.3V & +5V combined 150W max
12V combined current 39A max
(and a lot of other stuff on amps and volts for output).
Now, Watts = Volts * Amps.
So if I have 520watts and 12 volts would be 43 amps
If it means 520 watts and 3.3volts it would be 157 amps
However it seems to max at 39amps on the back for output.
I imagine input is all that matters here and at 520 watts and 100 to 240volts that would be
5.2 amps to 2.16 amps
And the thing says 7amps to 3 amps on the back for input.
So....I imagine that is the max it can pull before dying.
However, I have 4 drives, 4 ram sticks, and 2 quad core cpus all going and I would figure I am at least halfway or more of the power use.
And the power says it starts at 3amps anyway.
But I only get 2amps.
Just looking at getting a 1u box with a local provider. They provide .75amps per box.
Previously we have gone a bit crazy and gone with dell 1950s with dual quad cores and a few disks. As you can imagine these specs go well over the .75 amps.
What type of spec server would you recommend for that power? Looking at something for small scale web hosting, duall HDs and about 2gb of ram.
I am kind of new to the idea of colo and am curious how you know the amount of amps to purchase for your server? I want my machine to have enough to run efficiently without causing hardware failures.
quad-core intel xeon 3.0 ghz
8 gb ram
4 x 300 gb hdds
I have one server now which will be doing some intense PHP/MySQL serving. I want to grow into a second server that will handle the Apache server and leave MySQL on the original box.
Question is whether I can get something decent that will only pull .5 AMPS? Why? I have to choose a co-location provider and have narrowed it down to 2- the one I like very much because will give me 7U of rack space for $200 a month- but they limit you to 2 AMPS and my Dell SC1435 pulls about 1.4 at top usage.
The other option is another co-lo (closer to my home) that is just 1U space and costs $149 for the 1 Mbps burstable. So the it will cost $298 a month when I add the second server.
So can anyone suggest some decent low energy boxes for serving (for example) 250 very low storage CMS (Joomla) sites where the database backend is offloaded to another server (connected via each server's secondary LAN port)?
Here are my requirements:
A. Space: 1/2 a secured cabinet
B. Location : Bay area
C. Power: 8 amps
D. B/w: 1 Mbps
I got quotes from
A. www.bayarea.net for 1 cabinet with 20 amps $699
B. www.he.net for 1 cabinet with 15 amps $600
C. www.svcolo.com/ for 1 cabinet with 15 amps $695
I am wondering who can give me 1/2 a secured cabinet for around $300 to $400
As my clients' needs expand, they're asking for chroot ssh/sftp setup. I'm currently on a dedicated Linux setup but don't really have the time to set up a whole new box with full virtualization or investigate a full chroot solution (baby on the way), and to be honest it would be less hassle to move to a new provider than worry about down time with sites.
What I'm looking for:
- linux hosting
- hosting for 30+ accounts, some with several domains
- at least 6 IP addresses for SSL certs
- each account in a full chroot environment (ssh/sftp/ftp) so they can't poke around each others' files, or each account set up in a virtual machine setup (ie: openvz)
- maildir
- spamassassin
- php 5, mysql, perl 5.8.8
- suexec apache would be nice
I have learnt it is harder to setup than I initially expected (since I have just moved from a shared hosting service). I am in need of some help setting up my DNS servers, as I am very confused. Here is most of the info I know:
1) I am running HyperVM
2) I've installed LXAdmin
3) I own the domain (purchased from xeodomains.com) runemart.com
4) My VPS hostname is: vps.runemart.com
5) I know my IP
6) My host has said:
'For VPS customers that have a HyperVM login you can now host forward DNS on the DNS servers rdns1.vaserv.com (US)rdns2.vaserv.com (UK'
And I am unsure what this means/how to do it.
I am not sure if I need some more information to set up my DNS, however I am sure that I can get it if I do.
Now, my questions begin. Firstly, I need to point my domain - runemart.com - somewhere. I believe I need to set up my DNS via HyperVM or LXAdmin so that they are something like: ns1.runemart.com and ns2.runemart.com. Though, is this correct? Am I able to set up my own actual domain name servers, or will my domain have to point at something like rdns2.vaserv.com?
If anyone can assist me in this I would be very greatful, as I am waiting to get my website running. This is all I will ask for now, I will take it one step at a time =).
I am currently researching and evaluating Network Attached Storage systems and was wondering whether anyone out there has had previous experiences (good or bad) with any particular setup?
I am particularly curious to know:
1- what kind of a performance hit I can expect when data is stored on a NAS and accessed via ethernet over iSCSI as opposed to regular SATA or SCSI.
2- what pre-built NAS system would you recommend for a system that requires about 8 TB of disk space for file data and needs to have 100% uptime? I've been looking at: [url]
However I don't know what sort of limitations this hardware offers as far as simultaneous disk reads/writes go.

Hello I have my own web server. Due to some sites being blocked in where I currently reside (no not porn, just websites like flickr, orkut..etc).

View 6 Replies View RelatedWe are currently setting up a VPS server, which will be used for a specific client portfolio that we are aquiring from another company. This is a Linux based server with WHM/Cpanel.
However, we wish to set up DNS in the best possible way, since we need to host DNS for some vital ISP services also. I gather this probably means using a combination of DNS on the VPS server itself, as well as one or more other DNS servers in other physical locations. The VPS server itself is located in Amsterdam, while most clients are here in Norway - thus ensuring reliability for local clients is the most important consideration.
Now some key questions:
- How important is the physical location of the DNS servers, and where should these ideally be located?
- Is a cluster solution the way to go - and is this supported by WHM/Cpanel?
- We have Linux and Windows based servers on our local network; could these be used for DNS also? If so, tips on software needed?
I got a dedicated.
And 2 Ips.
I want setup ns1 & ns2 for my server.
how to ?
I use WHM.
i am currently experimenting DNS with my 2 ips (each with separate servers spread over 2 geographic locations) and my zone file maps these IPs to ns1.domain.com and ns2.domain.com.
Both of my servers run DNS and with zone entry for my domain name. But when i stop the dns server on first IP (ns1) the second dns server (ip2) not working or resolving. Both are master servers.
My question is if first server DNS fails, the second DNS should resolve? why it is not working. i guess that is reason why domain registrars ask for 2 name servers. if one fails other works as backup??
how do i setup these? should i setup a slave or something?

what exactly the problem?
All the domains on my server are using my own hosted nameservers, but now I have a new domain where I need to use a 3rd party DNS (gratisdns.dk).
The settings on gratisdns.dk wasn't a big deal, but what on my own server?
I created the domain through whm and it is set to use my own DNS just like the other domains. How do I change it to use the DNS from gratisdns.dk?
This is how my zonefile looks like:
Quote:

mynewdomain.dk. IN MX 0 mynewdomain.dk.
mail IN CNAME mynewdomain.dk.
www IN CNAME mynewdomain.dk.
ftp IN A 72.xxx.xx.xxx
I guess I don't need the A record and Cname here since I set that up at gratisdns.dk?
How should it look and are there anything else I need to change on my server?
