Own DNS Server In Rack
Apr 26, 2008
We have about 50 Cpanel servers in our own AS with two upstream providers. On the cpanel servers we use the following IPs in the /etc/resolv.conf:
1. IP of the cpanel server
2. DNS IP of the 1st upstreamprovider
3. DNS IP of the 2nd upstreamprovider
I realized, that the upstreampoviders nameserver are not answering that fast and therefore I was thinking to make my own DNS Server, which I could use additionaly after the IP of the cpanel server.
Is this a good idea or is it not necessary? If it is a good idea, which dns deamon would be recommended? If we build this server, maybe would be also nice if we could offer DNS as a single service. Is there any solution where we could create user accounts where user could manage there own dns zones?

With all the high power servers/blade servers, the 40A (@ 110V) power limit is way too small. I am wondering if there is any colo space targeted for high density application, e.g. with 10 KW/cab limit for 60A @ 208V power drops. Does anybody know of such high density colocation space? East coast is preferred.

I have a 6RU rackmount server cabinet, which I am putting a 1RU server inside.
I am wanting to put some fans in the metal cabinet, to bring in cool air, and let out warm air.
Does anyone know where you can find these sorts of fans?
Because the server inside the rack cabinet is closed, I can't use a fan with a Molex connector.
I haven't seen any case fans that use a usb connector, or just a normal power outlet connector.

I am trying to decide to run my heavy database community site over at a new host but am looking to create a good package customed for high bandwidth.
I can decide from going with ONE Dual Quad-Core 2.0 Processor(4 gigs of ram) or TWO Intel Xeon 3210 2.1 GHz Quad Core Processor servers(4 gigs of ram each) with a Virtual Rack Container.
With having both the lower servers on the virtual rack, will the site manage with the same power as the Dual Quad Core since it is on a rack?

I paid for a server with GeekRack.net 8 days ago, and have seen no sign of the server being setup.
Now I know they are just a Burst.net reseller, they don't own or order the hardware or even have physical access to the servers, they simply get 25% off Burst.net and just resell their servers. That said you'd expect at least some sort of notification on when the server would be ready by, especially by now, right?

a company gives me 40U rack with 16A by 600€ per month. It will be enough power to fill the rack with Dell servers R200/R300 with dual and quad core processors?

I woke up to a complaint by the ISP of spamming for one of our servers. More than 10 000 spams in a shared hosting environment. Found Steven online, thank God! PM him and he went to work looking for the culprit. He spend time monitoring and putting in scripts to catch the culprit and in no time found the faulty script causing the spams.
Really saved me a big headache on how to explain to the ISP. Thanks to the consistent excellent work done by Steven of Rack911.
Those unpatched forums of clients can really be a hassle and a big source of problems.

Our server count with The Planet only seems to be increasing as of late and I'm now starting to drive myself nuts with bandwidth counts, costs, etc.
My main concern at the moment is our total bandwidth. While we might have a server with a 2500GB limit only use 50% we might have a 1500GB limit use 200%. I understand that any overages are our own fault, etc but there must be a way for us to combine all bandwidth across all servers!
Is it possible for The Planet or any of the other big boys to provide private racks with pooled bandwidth without going colo?

I honestly dont understand why does DELL, HP and others price their 1U TFT monitors at 3 times the cost of the cheapest laptop?
I mean, dont get me wrong, I am all for spending good money to get quality products but I feel very awkward spending 3 times as much for a screen and keyboard when I can get their laptops WITH OS, MEMORY AND HDD for 3 times as less and use it as the 1U TFT monitors.
I can get a powerful server from Dell and HP at that price for crying out loud.
But then again, I might be seriously overlooking something here because what justifies such high price?

I´m having a problem right now. I need to buy a Dual Xeon system, to use 2 Quad Cores, however there are some things I need:
- I already have a SCSI controller (Dell Perc 4 (PCIe))
- I already have HD´s (3x SCSI U320)
- I want to use RAID5
- The chassis must be 1U
... my problem is that I never worked with SCSI U320, just SATA and SAS. I usually buy Tyan racks, more specifically, this one: Tyan Tank GT20 5381
It doesn´t have the option for SCSI U320, however they sell SCSI Backplanes that are compatible with this barebone. My question is:
- How do I connect a standalone card (like the one I have) to the backplane? Is there any SCSI connector on the backplane?
- Since space is a bit of a problem in 1U racks, are there any kind of cables that can do more tight turns inside the case?

What 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.

Does anyone have any recommendations where I can get a few cheap (full length) rack shelves in the UK. They don't have to be adjustable but would prefer if they where full ones and not the half ones as I don't think they would take the weight correctly.

I was having problems with a host and Ed (one of the owners) helped me out creating a custom package to fit my needs and moving my sites across.
I've posted more than my fair share of tickets and they all get responded to quickly. All the tickets have either been my own problems for example installing scripts or sales questions.
Server speeds are good for me and prices are low.

I have had bad experiences with zero-U PDUs (i have only tried the APC ones). They keep getting in the way of equipment when you put them in the back of the cabinet .... I usually end up just having them standing up in the back of the cabinet and zip tie them to something so they dont fall down.
Am I just stupid and using these wrong or do other people have this issue? if you have an extra long server that sits out the back it bumps into the PDU so you got to nestle the PDUs into a corner of the cabinet.
What PDUs is everything using in various co-los? I might go with the 2U rack PDUs but with the need for 2 of them that is 4U wasted (and also since they are not very long you need some long cable runs for all of the equipment to plug into them)..

Have an issue that I am dealing with, APC support couldn't really help me get anywhere either.
Here is the story:
I am leasing a rack at Equinix in Sunnyvale.
It came with 3 APC Switched rack PDUs.
By the looks of it, they were used by the previous customer.
APC sent me a serial to RJ11 programming cable, and I have been trying to use HyperTerminal, but I get a blank screen when I attempt to connect.
I have tried arp commands, but, again, it looks like the device was previously configured.
I downloaded this: [url] hyper terminal software.

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.

we would start to offer colocation in our rack but i would know if there any system that will limit the customer access only on the 1U or 2U posistion where the server is located inside the rack, so nobody can touch other servers

I have a Switched Rack PDU AP7921 in use and it was working now for several months without any problems. But sice yesterday I have a problem with the network connection. I was not able to connect to the PDU anymore, after pressing the reboot button it was working again. But after a few minutes, the problem appeared again.
Is this a common problem of this APC PDUs? Is there a fix, for example a firmware upgrade or is it broken?

where about I can get a decent 1/4 rack for a couple server's I'll be using and selling. I was thinking BlueSquare or Savvis. Blue square would be decent, although I don't see a price scheme on there website.
Poundhost, who are in the BSQ have been the most "attractive" to me. The rack is £260/month although It has a few thing's I would need more of and not sure if they offer it.
1) I will need atleast 50 IP Adress's
2) I want 20,000GB transfer on the rack, so each server get's 2000gb.
I was wondering also these question's:
1) Do I have to go to the datacenter personally, or can I send the server's down with a courier?
2) Is there a way on a rack, to limit each server to a set ammount of bandwith?
I'm asking these question's as I've never had a rack before, nor colocation, It's usually been dedicated. I've been looking to get atleast 50% of them quad core server's and hope they would sell like hotcakes.

Where I'm certain that this is a gateway issue, perhaps experience will prevail, where someone having experienced a similar circumstance will have a solution.
We have a box, running CentOS 4.3 (64 bit) that has an 8-block at LayeredTech through ZipServers. Strangely enough, two of the IPs are operating at a reduced speed!
To test the matter, we've posted a file shared across all IPs (/var/www/html/testfile.gz), and when downloading through different IPs, the speeds are different.
For example (fictitious file links):
72.232.186.42/testfile.gz (DL at 350k/sec)
72.232.186.43/testfile.gz (DL at 350k/sec)
72.343.186.44/testfile.gz (DL at 350k/sec)
72.232.186.45/testfile.gz (DL at 70k/sec)
72.232.186.46/testfile.gz (DL at 70k/sec)
Further, this isn't related to Apache, as FTP is affected in the exact same manner. If we FTP into the machine using a same account, but with different IPs as hostnames, the download speeds differ just as the HTTP downloads do.

After running 6 or so dedicated servers purchased thru several different resellers, my company decided to get a rack at the Chicago InterNap DC.
The quote we got was $3,400 per month inclusive of cabinet, Usage based 10/100, and Cross connects.
Have a couple questions.
A) Is that price in the ballpark of where it should be?
and
B) Our quote states Usage based 100mb Ethernet (10MBps Min). Tier2 at $150 month and $1,400 for the 10.00 Mbps Base. Being new to this, I have no idea exactly how much bandwidth we can use before the "usage" fees kick in.
How does this work?
