What do you think about this cabinet style's ability to cool say 18-20 1U core 2 duo servers? [see attached jpeg.]
its got a fan in the ceiling of it. I have read that ceiling fans don't do much and its the front to back cooling that really makes a difference. Is this true?
If you don't like this type of cab, which type do you like?
Just wanted to get some opinions. I assume you are trying to colo, and you will fill 1/2 rack in 1 year. I have two options:
1. Get 1/2 rack, 20amps first and get another one when full.
2. Get full rack, 20amps and add 20amps later.
The first one will save $250/mo. The second one will give you redundancy and privately your rack/cabinet.

I don't think a CMS is the way to go (learning curve is too great) so I was wondering if anyone knew of a website software similar to Site Builder (but not Site Builder) that will allow a customer to edit their own content? Or maybe suggest an easy to use CMS~

Seems that every host I've used has to be *told* about major problems, such as the server or database being down completely. I'm tired of going out of town fearing a site crash. I don't expect them to catch every problem, but when the failure is so blatant, it would be nice if they caught it...
How would I find a host who does this?
This is a bit off topic but I am looking for a person kind enough to test install a few RPM packages on an AMD 64 bit system with a 64 bit OS (Fedora or otherwise), preferably an Opteron but not required. The RPMs in question are IBM's DaCS which is something designed for a supercomputer yet to be created. We have one part of the DaCS model but oddly enough, we don't have any AMD systems (tons of high end Intels however).
On Intel machines, after installing these RPMs, the binary that is to be run (/usr/sbin/hdacsd) fails with a "Floating point exception" so I'd like to find out if this is an issue caused by a 3DNow optimizations to these RPM binaries (Intel does not support 3DNow) or something else.
I've put up the RPMs at [url] and the main one to be installed is dacs-hybrid-3.0.0-7.x86_64.rpm
After installation, run hdacsd (possibly in /usr/sbin) and tell me if you get the floating point exception.
my server seems to have lost its ability to do name lookups:

Anybody have a good source for APC cabinets? I need a full truck-load of AR3100.

View 14 Replies View RelatedLets assume I have the following equipment Hardware Firewall, Switch, 1U KVMoIP, 1U server and a 0U APC Switchable Power strip.
So there is 1 FastE ethernet drop.

Switch -> KVMoIP

Of course, then

My question is, which comes first after the FastE drop, firewall then switch or vice-versa?
providers who might have a cabinet available at PAIX?
We just got a great deal on a Gig circuit to PAIX, but the carrier doesn't have space available.
We'll probably to putting in a 6506 - so at least half a cabinet, most likely a full one.
We don't need bandwidth, just a cabinet and power.
We recently began to mirror a large number of open source projects with a dedicated mirror server on our network and I was surprised not only with how popular the mirror server has become, is, but also of the ability of the hardware we're using to keep up with the load.
At an given time, the mirror seems to be pushing at least 50 Megabits of trafficthe server is also an IRC server (irc.igsobe.com) for customers and internal staff communications.
The hardware is a low end Dell Pentium 4 @ 2.66 GHZ server, running with 512MB of RAM and a 400 GB ATA hard drive. CentOS v5.3 is the operating system.
If you're interested, you can view the HTML logfile analysis here but that doesn't tell the full story as FTP users make up a good portion of the traffic. We've received over a quarter million hits in the first few days of November alone.
18:14:15 up 65 days, 9:04, 5 users, load average: 0.31, 0.69, 0.56
The only change that I made to the default configuration was lowering the maximum number of Apache servers to 128.
Just thought I'd share this information as I wouldn't have thought a server with such a small amount of RAM would be able to serve up so much data, even though we are talking strictly static HTML files.
I'll definitely keep this in mind when clients ask me for those "what type of dedicated server should I use for XXX" type discussions that are had all too often with clients.
if I rented a half, or full cabinet for colocation. And would wanted Cogent was my isp for the cabinet how much do they charge?
Days they take to setup?
Costs to setup? (Setup fee?)
I know their pricing 100Mbps for $1,000 which is pretty crazy deal. And if I would go on their contract would it save me a setup fee?
I currently use a half cabinet and think I'm paying way too much. I pay $1,000/month for half rack (10 meg bandwidth) 20 amps power, etc. Service and connectivity has been great (Ashburn, VA data center) but I think it's just over priced.
What should I pay for half cab, 20 amps, 5-10 MEG bandwidth, 20 amps?
On that note, what if I was to go for a full cabinet solution, same power and bandwidth, what is ultimately the expected price for a reputable colo provider?
I use APC Netshelter cabinets now; I have a need for some cabinets with 23-inch wide rails, capable of holding telco muxes, rectifiers, batteries, etc. Any suggestions on cabinet?
Something that would blend in with APC Netshelters (black, bowed/curved door on cold aisle) would be nice. I know I've seen a cabinet very similar to Netshelter delivered from NetApp, but with a grey/off-black color, and 1-piece door on the hot aisle. If APC is just sourcing their cabinets from some manufacturer who takes engineering requests, it would be great to find out who makes them.
I'm planning to move my co-located server to a cabinet soon. We are adding dedicated web & database servers to take the load off of the main box. I will get one GigE drop in this cabinet, so obviously I need a switch.
No routing is needed on my end, so my guess is that the regular GigE switch would do just fine. But I have few concerns about my setup.
All of my servers have dual GigE port. My plan is to connect one to the internet, and another to a local private lan for SMB, database, SNMP, and such. Jumbo frame is enabled on a private lan.
Is there any 16-port switch that allows me to assign 8 ports into one virtual switch (1500-byte frame) and another 8 into another virtual switch (9000-byte frame) ?
On the internet side, I expect to be pushing around 300-400mbps, a bit higher on the private lan. I need a very stable switch that won't choke or crash at this rate.
I'd also like to be able to limit throughput on each port, and probably do port/ip filtering on this switch instead of iptables on each box. (Am I asking too much for a switch?)
If I colo a full cabinet with anyone like colo4dallas, calpop or any other random host:
Does it mean they give me a cabinet I can put my servers in
OR
Do I have to bring my own Cabinet?
When looking at the 1U's, I have to search really long and hard trying to find a half-decent host. A lot of companies skimp on something when offering colo, and makes for a bad day when that particular service is needed.
On the other hand, I see a lot of colocation offers for great deals on Cabinets and half Cabinets. High, premium bandwidth, PLENTY of amps, top of the line support, etc. It would be tempting to go for these, except I only have a single unit server.
I was going to give up on finding a good colo, then I got an idea. What if I got together a few other people, we all pitched in for our slice of a cabinet, and bring the price well within reasonable limits for those of us with low demands?
Would it be too difficult to do something like this? If you run across this topic and are looking for colo, would you be willing to give this a shot?
Where is the best place to buy shelves for a dell cabinet?
View 1 Replies View RelatedI'm about to move 31 machines into a 42U full cabinet
Previously I was on an uncapped bandwidth provider but we had a lot of problems with them so I decided to find a new provider who charges bandwidth by mbps
I do not have mrtg installed or managed switches, but I may start with 10mbps.
But I'm just curious, what takes a full cabinet with more than 30 machines does the total bandwidth takes you.
Perhaps any colo provider here don't mind to share their stats.
I'm currently colocated in 365 Main in San Francisco.
Due to power limitations there I need a new place with 1-2 cabinets, about 25Amps and 1-2mbps committed.
I'm looking for a long-term, reliable, 24x7 NOC, with no surprises. If my servers are down, I'm out of business, so uptime (power+network) is the most important factor.
I will summarize the recommendations I get and post them back here.
Please do share if you know of a 10TB colo offer in either east or west. I know co-location is bandwidth-based but this is what we're looking for right now. Here are the requirements:
10TB (up and/or down) transfer on at least 100Mbps port
Good uptime history (BGP mix, A/B redundant power feeds, redundant hvac, etc)
Friendly crew (willing to help rack up 1U's if it's remote)
20A circuit (willing to consider 10A)
Access to KVMoIP
Ethernet drop
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
Not interested in reseller plans or any of that - strictly as a site for domain purchase and personal site hosting. I have them and am becoming very unsatisfied and looking for alternatives.
