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......
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.
I'm looking around for a nice, cheap colo place for a Dell PE 2650 I just purchased...
* At least burstable to 10Mbit... dedi 10 is nice.. 100 is nicer..
* About 1000GB xfer should be good to start, I guess I can work with less
* Cheap IPs with no problems obtaining more
* Cheap remote hands since there's really not much in the RI/MA area. I will be going to school in upstate NY so I guess something around there would be cool too. I'm willing to ship anywhere though.
* Discounted/included DirectAdmin would be really nice...
* Not going to be selling IRCd stuff unless it's allowed and nice firewalls. I will probably only use it for a personal IRCd and irssi session.
* Joe's Datacenter [url]
This company seems too good to be true... they offer great services for great prices and have many good features. I also spoke to an admin who said he will be able to include a DirectAdmin license for free. They include 5 IPs right off the bat. I got about a reply in an hour at like midnight from Joe (or just another Joe) himself.. and I'm not even a customer! They do free reboots. $50 to colo our 2U with 1500GB and 100Mbit. It's 25 extra for unmetered w/10Mbit but I'm sure the admin would be willing to just offer more b/w staying at 100Mbit instead of moving to a 10Mbit port.
* FDC Servers
Great reputation.. Pretty good prices for what I would imagine to be quality service. Not much more I can say about them.. Did not ask them about DirectAdmin.
I think I'm mainly just looking for any input on Joe's Datacenter because I really think I want to start my company there. If anyone has any better offers I'm open to anything.. but DirectAdmin would be really nice... just remember that.
I'm also looking for a solution to HyperVM... LxLabs (to-be LxCenter I guess?) is now releasing it for free.. I'm not sure if it's patched yet or not though. I think I might just start with HyperVM for now since noone is going to target us.. seriously.. we are two kids with like 2 clients right now. We can always migrate later if HyperVM never takes off again.
What if i got a really good connection to this house i have in Sweden and bought some servers there, is it a good idea and would it sell? How hard is it to get a good connection, the house is in a fairly populated area of Sweden and i have partners who could help run it and do support 24 hours.
But its just a thought and we would start small. What do you guys think?
I just got a phone call yesterday because my house I just moved into came with a small peice of land about 3 miles away * no clue why* And a company wanted to rent it out for colocation. Is this a scam or should I do it? They said it would only hold 60 servers. The building on the land they would be renting already has backup generators emergency lights etc just no internet leading to it.
My company is about to start a project and need about 100 servers within 3 months. I am looking for a list of afordable and reliable unamanaged server providers from Europe. Can you suggest some? Which datacenter should I contact for such a project?
I want to get a server in Toronto and am looking for some datacenter recommendations for the area. I seen a thread from last May but would like some more current info. Iíve been looking at either ColoHotel or 3z, does anyone have any experience with either of these locations? Also does anyone have any other suggestions on who to look at or who not to?
My requirements are pretty basic 100Mbit would be better then not, remote reboot, 24/7 access.
we're in the process of revamping our website and was curious what you, the customers, look for when going to a datacenter's website. Do you like seeing customer comments? Upfront pricing? Facilities' amenities? Which providers' websites do you think are good examples of what a good website should look like?
I am making some business plans and having an independent datacenter is one of them. Certainly it isn't easy as leasing a space, and buy some stuff. Some of the things I have to watch out for are network activity, getting bandwidth support, power supply, get an engineering company to design the facility and a lot of stuff.
Are there any companies who handles all that? What would be the specific steps to accomplish my agenda?
Does anyone know of a reseller (as gigenet doesn't sell them directly AFAIK) of VPSs at the gigenet datacenter?
I need a new VPS for a new project and I'm looking at one located in the midwest and Chicago seems a perfect location. My project isn't big enough to require a dedi, but I was hoping to find a vps company who has nodes at gigenet.
I've heard people talk about it being important to pick the right datacenter if you go with serverbeach. Other than the two power outages in the VA one, what are the differences? Do they all use pure Peer1 bandwidth?
We are going to be moving our 10 Servers and various other equipment to a new facility here in Chicago. I have a few question I wanted to ask to backup my current thinking.
We are primarily a web host so all of out users either have their DNS set to our DNS server or they have a dedicated IP and an A record pointed to it. Currently we run a private NAT and have private IP's on the internal servers. The firewall handles the NAT'ing between the public and private IP's.
The primary question I have is if we change the IP address at our registrar for our DNS will the change still be subject to the 24-48 hours of propagation? Since we are not changing the NS records and only changing the IP's I would have to assume that his changeover should be fairly quick.
Two, im looking for the best way to setup our new cab are they any network admin photo gallery's?
