I am looking to move into a colo facility in the Denver area, and I would like to find out about pricing and availability on 10gige uplinks. I have not yet selected a colo facility to use, although I am considering ForTrust Solutions.
My network topology looks something like this:
(colo facility provided router)====>(10 gige uplink)====>(Nortel 5530 switch with 10gige uplink port)===>(30 load-balanced web servers with gige NIC's -- using LVS direct-server-return load balancing)
My expected bandwidth utilization is ~1gbps based on 95th percentile accounting. However, I seem to attract some massive DDoS attacks; so, having the ability to burst up to 10gbps of bandwidth seems like a good way to deal with the problem.
How much should I expect to pay for a 10gige uplink with 1gbps of utilization in the Denver area? Which colo facilities provide such uplinks?
Also, since I am not multihoming, can I expect the colo facility to take care of setting up a BGP'ed router?
A better question might be whether you can expect the colo provider to welcome your DDoS heavy traffic. It isn't certain from their website if Fortrust provides a network to their customers. Even if they do, chances are their (or most colo provider's) network does not have over 10 gigs of capacity, nor would it necessarily be set up to withstand DDoS.
With that sort of traffic you should really be running your own network with your own uplinks from your own providers, with your own (expensive) 10 gig gear. Otherwise you would be buying a gig of marked up bandwidth which I would advise against (unless it's on my network)

You will have a more difficult time finding good 10 GigE connections in Denver vs some of the major locations such as Ashburn, NY, SJC, LAX, etc.
You will have a very difficult time finding a 10 GigE connection in Denver with a biz model as a DDoS magnet.
I am not aware of ANY carrier that will do a 10 gigE connection with less then a 2 gig commit.
I would suggest that you get two GigEs from a low cost carrier such as Cogent, and bond them using etherchannel or link aggregation. Two fractional gigEs will cost you in the neighborhood of $10k per month, versus way over $20k a 10 GigE with two gig commit.
Since we have not yet selected a datacenter for our new servers, I think the question I should be asking is which datacenter should we use?
We have 42x 1u dual-core dual-processor opteron 270 servers with 4xSATA drives each and 8gigs of RAM.
We need to colo all of these servers together and run gige copper from each of the servers to a central aggregation switch. We will be adding 6 1U servers each month.
We will start out with aggregating 2x1gbit circuits with etherchannel.
Our main office is in Redwood City, CA. So, I have thought about going with Market Post Tower and 365 Main, however I am concerned about power limits that may be placed on each rack -- I've heard that a lot of bay area colo facilities are doing this.
Where would you reccomend we colo? MPT, 365 Main SJC? How about the new 365 Main facility in Chandler, AZ? Denver?
We've been using Hurricane Electric, however their 15amp limit per rack is unacceptable -- that leaves 36-37U of a 42U rack empty.
quilner: ' the question I should be asking is which datacenter should we use?'
First response is: it depends on where your traffic is GOING. If your traffic is standard web traffic going to domestic US, recommend a colo on the east coast as the majority of the population and traffic is on east coast. That would suggest Equinix Ashburn, Newark NJ, 60 Hudson NYC, etc.
Then start whittling away on which ones have carriers with 10 GigE ports, that are carrier neutral, which one have space availbility, which ones have the power you need, and which ones have decent costs for power, with decent costs for cross-connects, without huge installation fees. The list gets short really fast.
Do _NOT_ get locked into a carrier data center if you are truly gonna need 10 gig ports in the long term.
'have thought about going with Market Post Tower and 365 Main'
Nope -- no carriers have 10 GigE ports at MPT, and 365 Main is a power fiasco
'gige copper from each of the servers to a central aggregation switch.'
Also take a look at the Cisco ws-c4948-10ge-L3 It has two 10 gig uplinks, 48 copper gigE ports, and a 667 Mhz cpu. Regrettably it doesnt do full BGP, and only supports 512 MB RAM.
A large portion of our traffic goes to Japan, with the balance going to the continental United States.
So, I assume that means I should be restricting my search to Texas, Arizona, Colorado, Oregon, and California. However, it seems that Texas and Oregon have the best prices on power. In Oregon, I've got the carrier neutral Pittock Internet Exchange on my list. Any reccomendations for Texas?
Any thougts on Pittock in terms of power density per rack and space available?
We have gotten several circuits aggregated in that manner as well, one of our providers actually almost demanded we do it that way.
Yea, none of the above really make any sense to me either. I'm not sure why BGP/ECMP is not a more prevalent option. Perhaps all of the enterprises can't think that hard, insisting on OSPF or L2 agg, so now the carriers insist on dumbing themselves down too. *shrug*

We are *not* a reseller. We own our servers, switches, routers and racks.
Unless you have good credit and well established no provider is going to give you 10 gige uplink especially if you are only going for a 1gig commit and DDoS heavy traffic. You will probably need to go with a reseller.
Even at the 1gig level you are playing with FIRE signing anything over month-to-month contract if you are Heavy DDoS.
