I'm specing out a box for small dedicated servers and am looking at the SC512 with a desktop board (Intel D964GZISSL since I don't have to cut anything). Should I be using active cooling since it's a desktop board, or will a large passive heatsink be sufficient? I'll be using Celeron Ds, probably a 356. It's power usage is quiet low.
It looks like the heatsink on the motherboard might restrict airflow a bit.
if anyone has tested any of the new boards by Intel or others for LGA1156 processors in the Supermicro SC512L chassis? And how is there compatibility with CentOS? ie: the P55 boards by Intel
I seem to have gone over this a hundred times, but wanted to get feedback from the community. Has anyone out there been able to really make liquid cooling work in their data center considering the additional space utilization and expensive price point.
We've found that liquid cooling vastly more expensive than what we are doing and am curious what some out there might be doing.
For us we've found that high density air cooling (top down, and capped hot/cold row configuration, and overhead air extraction) can get us to a max density of about 10 kW per rack. We use a chilled water system for the additional HVAC needed to get us above the standard 5 kW max, but this is for the air handlers themselves and not chilled water for the in row rack cooling. The problem is the in row chilled water cooling makes us lose a cabinet of space for every cabinet of higher density. For this to work (simple situation) we would need to attain rack densities of at least 20 kW given the loss of floor space.
We use APC Cabinets and infrastructure and even they have said if you try and get about 20 kW with the liquid cooling it becomes problematic. Given these governing characteristics in addition to the overwhelming cost, is anyone out there actually pursuing this in a colocation environment. To me it just doesn't seem to make sense.
Perhaps the cost needs to come down, but even then what are you gaining if it is a 1 for 1 trade off.
The company I work for is starting to have some cooling issues in our server area. We have basically doubled our server equipment in the room without upgrading the air conditioning unit in the room. Temperatures are getting really high in the room (sometimes reaching 85F which is just WRONG!) and we are trying to get it replaced.
Since my boss is the one making decisions I thought I would try to help him out a little bit with some of the information/calculations he needs.
My questions are:
1. When calculating watts for a redundant power supply do you double what the power supply is rated for? So on one Dell PowerEdge 2950 it shows that I have a 750W redundant supply. Would that be 1500 Watts?
2. Do you calculate your cooling needs for max wattage or do you calculate a percentage of what each power supply is rated for?
3. What percentage would you multiply your final total Watts by to accommodate possible future additions? 10%? 25%?
We currently have: 2x PowerEdge 2950 - 750W Redundant 1x PowerEdge 1950 - 670W Redundant 2x PowerVault NX 1950 - 670W Redundant 1x PowerVault MD3000 3x APC Smart UPS 3000 1x APC Smart UPS 1400 2x PowerConnect 6224 2x PowerConnect RPS-600 3x PowerConnect 5324 1x Cisco 2801 1x Cisco 2821 3x Unknown wattage servers redundant power(All the same specs) 1x Unknown wattage server redundant power 1x Unknown wattage single power supply Then a few other small devices like external modems, KVM and a small-mid sized phone system.
I am not an electrical expert but I am calculating that it is going to be about 10,000 - 12,000 Watts?
Equinix Secaucus NY2 (275 Hartz) seems to have cooling prolem for the last 1 hour. The whole DC becomes hot. I went out one hour ago, came back and it's so hot now. I don't have temp now, ut I think it's around 85F (up from around 65F typical).
If you are in the DC, have fun working ... I wonder how much longer I can work here Hope they fix this soon, or else......
We currently put 2U solid spacers on the front. As well, I run the switch with the ports facing frontward and use a cable manager on top and bottom of the switches.
I can see from some of your pics in the other thread....that you place the networking equipment in reverse. It depends on how the fan is facing on the networking equipment as
I don't like to have fans facing the inlet portion of the rack.
1) From time to time my vbulleting message board loads slow, and at that time the server isn't even at a high load this happen at loads 0.9 nothing much really but always below 4.
2) Not only does it load slow but it often return the server cannot be found error, this minute it works fine and the next minute it doesn't, all i can see from the error log for my domain is
3) php warning: Zend Optimizer for PHP 4.3.x cannot be found (expected at '/usr/local/Zend/lib/Optimizer-2.1.0/php-4.3.x/Zendoptimizer.so') - try reinstalling the zend optimizer in Unknown on line 0, referer [url]
4) Does vbulletin relies on zend at all to be fully functional?
5) will zend actualy help at all?
Yes there are other sites on the box and they seem to work fine. rhel4, ensim X 10.1 with all hot fix to date. php4 mysql4
Have ipb forum and im in need for a new server spec.

Does anyone know of a provider that has an Ubuntu Desktop VPS? I've got accounts with fsckvps and xensmart but they only have centos ones - I'll install gnome on of them if I really have to but i'd prefer todo as little leg work as possible as it's for personal use.
This is a little bit Offtopic here but maybe it's okay to ask my question.
For my GUI software development i need a virtual server solution. It must run WinXP, WinVista, LinuxI386, LinuxAMD64, FreeBSDI386, FreeBSDAMD64 and Solaris.
I'm currently running VMWare with all this systems. But their KVM tools are very instable - especially when waking up from hibernate etc. They eat the key/mouse focus and the only way to get any reaction is often a hard shutdown.
How good are the other Virtualization Kits? I heared that FreeBSD does not work on VirtualBox? I'm especially interested in Xen but i'm not sure if this is good for Desktop use. Seems that it is promoted almost exclusively as a server solution.
I am a CS major in college and new to these forums. I wanted to start by saying Hi and asking if anyone has used Spiceworks (spiceworks dot com) and had any complaints/praises? Also, are there any paid alternatives to the product and how do they match up against it.
Id like to know if I could use a remote desktop ( remotely ) as I have about 350msec latency to the server where I am planning to install it. I am planning to use remotely anywhere server .
The directions I recieved were "Please use remote desktop to connect to your server."
So I entered the ip address into the remote desktop connection window and it doesn't connect. Where do I go from here? I searched and can't find any relevant info.
I signed up for a Win2k3 VPS account with 3dgwebhosting. I'm a newbie to Plesk and win2k3 so I spent the first day getting head around Plesk.
I then logged into Remote Desktop only to find someone else had beat me. They'd hacked in and downloaded a mass email client, email stripper and obviously sent out spam from a 2mb text file of email addresses.
I didn't spend long in Remote Desktop, but while there I switched on Windows Firewall, changed my admin login password and logged off. Now, 24 hours later, I can't get back in. I get the error - This computer can't connect to the remote computer. Try again.....
I can still login through Plesk, FTP and ExpressionWeb.
Is FW keeping me out of RD or has the hacker returned?
I am setting up xampp on my desktop and when at home, I can develop on either the desktop or my laptop using xttp://localhost/ or xttp://desktop/. When I suddenly need to travel, what's the best/easiest/fastest way to make sure I have the files I need to work with on my laptop?
Is it to install xampp on my laptop, and then copy the files I need from /xampp/htdocs over from the desktop? How would I copy the MySQL databases over as well?
I was also looking into Microsoft's SyncToy 2.0. When combined with scheduled tasks I can do automatic sychronizations once per day. Multiple times per day would be ideal... but I could set up pairings and do manual copying everytime I need to run out.
Are there better ways? I could install the 'master' server on my laptop, but I would prefer to keep it on my desktop (more space, more power, etc.)
