Colo Layer-3 Switch...
Dec 27, 2007
I currently have a rack of gear in a nice colo. At first this colo was established to provide for some of my own equipment. However, in the past year or two I have had several customers express interest - so I have started reselling some colo space to them.
Currently I have three network feeds from the provider coming into my cabinet. I am about to add a 4th feed. All of these feeds have been added so that my customers could have a dedicated connection to plug into their hardware firewalls.
Since I am growing and about to add a 4th customer, I am now trying to figure out how to simplify this, and better provide for future growth. I am thinking that the best way would be to have one "feed" from the provider. Then I would bring that one feed into a layer three switch which I could use to break the feeds out to my customers. This would also allow me to measure the bandwidth being used by each customer and bill them accordingly.
Does this sound right to you all? Also - any recommendations on a good layer-3 switch?

i have two servers colo on the IDC,
i want to search for a Layer 2 Switch for them,
the bandwidth we use now is about 5-10Mb only.
i hope the switch is reliable,but not expensive,
i do not need a lot of feature,just reliable for the connection for my service.
i find some cheaper switch,like d-link,ProCurve,

I'm investigating "suspects" that could be used in a server access environment. My requirements are:
*24 or 48 10/100/1000 Mbps Ports
*Atleast 2 x 1000Mbps uplinks (fiber preferred)
*SNMP-enabled for remote bandwidth polling @ ports and uplinks
*Simple Layer 3 allowing for per port rate limiting
VLAN creation support would be a plus, but not required
The switch needs to be able to handle ~1000Mbps of constant usage
I would be open to using non-Cisco switches as well.

Here's my plan: colo servers for VoIP in either Switch and Data NYC or Telehouse NYC (or possibly Equinix Newark NJ). Purchase bandwidth from InvisibleHand.net, who can give me a direct connection of IP bandwidth from DTAG DeutscheTelecom
People say DTAG has awesome bandwidth, and I know I can get it pretty cheap from InvisibleHand.
Any comments on this plan? Which of the 3 locations is best for the price? I don't want to buy from a reseller (since they may go under). I want my colo direct from whoever owns it like Switch and Data.

3Tera's AppLogic could be the expeditor of a lot of small and medium dreams. I read the whopping 28 pages thread about TGL, it sure got my juices running. With enough time, the grid could evolve into something close to a Matrix (and hence the thread title).
Yet it seems it wasn't stable yet (at that time). And 3Tera and TGL were talking about features yet to come. So my question is:
Is their service stable yet?

Anyone else seeing packet loss / high latency? I was told that Savvis and or Layer3 are having some routing issues tonight.

From the real experience, how many mbps can it process in layer3 mode with 10-20 VLANs?

Is there a colo provider that has a free private network for use between their locations, similar to what SL has for their dedicated servers between facilities? They have 10GigE between their locations, with free unlimited usage.
We have around 40 servers now, and colo would really make sense, but we are doing multicasting stuff so we really need a backend network to support our services, as well as many locations for better delivery quality.

a sales told me i can buy two switch and do series connection,
then if one fail,another will continue to work,
it will take high HA,
but i still can not understand how to do it and work,
could you know what it is?

Please give me the difference. Colo in carrier hotel, we can choose our preferred network provider, but should we do that if we cannot have our own tech in datacenter? How about the supporting service from carrier hotel? Just general question, cause I dont address exactly which facility.
And the second would be more expensive? Saying the same number of rack, amount of bandwidth... Who is providing IP addresses then?

I currently have a dedicated server, which is hosting several websites. I'm happy with the service I'm getting, but I'm trying to save money. I'm paying $120/month for the dedicated server. Spending half of that each month would be great.
Right now, the websites are either static websites, or are simple database driven websites with not much traffic. My server load averages are pretty close to 0.01
I would think a VPS would be fine for my needs. However, I may have a site I will host in the future that is database driven and uses Ruby on Rails. It would probably have 10-20 users online at any given time, and maybe several hundred subscribers total.
Would a VPS still work in this instance, or should I stick with a dedicated machine?

I'm sending off about 6 servers off to colo soon, and looking for a basic switch..
I would prefer it to be a Cisco switch (but doesnt have to be, just that i'm used to IOS), not used.
Fairly cheap and nothing overkill. Just going to be pushing 20Mbit/sec.
Must haves : vLan capabilities, SNMP, 10/100mbit upink, able to cap ports at non-standard rates (eg. 1mbit/11mbit).

I need a basic L3 switch for maybe 25 mbps that will do hopefully up to 50 VLANs and which will not require me to hire someone to configure it.
As much as I like Cisco, that rules them out.
The reason I'd like a Layer 3 switch is so that I can run my backups and inter-server transfers without adding to my bandwidth bill. Also, VLANS are a critical requirement as i have a lot of customers with root on their managed servers.
So i am looking at HP [gasp] switches. How "easy" is the web-based configuration widget? [I'm an advanced unix admin but networking is a mystery to me.]
This is a starter switch and once i have a full cab of servers I'll be able to spend $7K on a pair of 3560s and hire someone to configure them for me ... but until then what can i get to meet my requirements?

This week connectswitch's service has not been that good. Basically first they restart the node without prior notice and our vps was down for 7 hours. and now we buy our cPanel license via them and they havent paid it so the license is now expired although we have paid them for it.

But we need opinion about Force10 S150 or Juniper EX-2500?
Or stay with Foundry and its SX1600?

which switches to buy as there are a myriad of options out there and I'm quite frankly a bit lost.
After reading through a bunch of posts here as well it looks like most people are leaning towards the Cisco Catalyst or HP ProCurve lines.
My requirements are:
- min. 24 Ports (4 SFP ports) 10/100/1000
- Layer 3 routing
- Low latency is more important than high throughput
- Switches will handle a lot of UDP multicasting, thus adequate buffers are important to minimize packet loss due to overflowing buffers
- Budget is ~$2k/switch

What is the purpose of making the switch. If i were to get "unlimited/umetered" shared hosting with cpanel, how is that different then getting a vps with cpanel?
Other then getting large amounts of traffic, what is the purpose?

We have a small hosting company (currently 24 racks) that we are expanding to hold 100 racks. We have several 3640 series routers behind a 7200 series router (our edge router) that feed into numerous 2950 switches and 515 & 525 pix firewalls then into the racks with customer supplied switches within the rack. I want to replace all the 3640 and 2950 switches with a 6500 series switch. The only routing we do within the 3640's is subnet routing to the switches which make up individual networks for each customer. My goal is to use the 6500 switch to limit bandwidth for each port feeding a customer and to eliminate all but the 7200 router and the 2950 switches. Does anyone know of a reason or reasons this would not work or if it's just a bad idea. Looking for pro's and con's,

Does anyone know of a fairly low cost dual power supply Ethernet switch. Nothing fancy is needed, just a simple 12-24 port switch that has redundant power features.
Our router and four little servers all have dual power supplies. Two big UPS units in a redundant setup would work great for us. The only weak link in the setup is the switch.

I just bought 2 Gbit dedicated bandwidth for me, and my customers. This is the switch the DC gave me. I know it is a 24 port switch, that can handle up to 4 Gbit of bandwidth. And that you can give each port its own dedicated bandwidth.
But this is my question. Off this switch can I give metered bandwidth? Like 2000 GB Bandwidth?
Also how would I offer unmeterd bandwidth? Like hook up a cheap Linksys up to it and limit the bandwidth to the port that the Linksys is in?

I was just wondering what switch everyone would recommend for running a back-end network. We plan to push mainly backup and management traffic over this network. The idea is to have an NAS box connected at 1GBit/sec and all of the servers at 100Mbit/sec backing up to that.
We currently use Cisco Catalyst 2960's to connect the servers to the front-end so it would make sense to use 2960G's for the back-end to keep the overall management of things simplified. There is of course quite a big price difference between a standard 2960 and a 2960G.

one of my clients build out their network but are still green when it comes to the switch market that I decided to get some input :-)
Pretty much, we're needing the following:
- VLAN support (standard thing)
- Per IP accounting (sFlow/netflow)
- multiple uplinks and ability to segment?
Pretty much, we want to be able to be able to seperate our network to allow for us to have cheaper providers for high bandwidth usage and then the other side for gameservers and things like that.
Now, I'm thinking that maybe it would be better to BGP the two and simply separate clients by their IP space. Now, my next question is that sounds pretty straight forward, but can we control BGP on a low number of IP's? Say we have a user with 1 - 2 IP's for a single gameserver, can we control it so say that IP only gets Provider #1 in their transit?
I've been checking models of switches and have found both the HP 2848 and the Foundry FES4802. Both are within the same price range which is nice, but the foundry seems to offer IPv6 and layer3.

I have been thinking of getting a switch/router when I rent 10U´s of space in a DC, but what to get?
I need to be able to read the trafficusage on each port/IP for billing purpose.
havent got a clue what to buy, have been told that you can do it with a 1U server to get more statistic out of it, but what OS to use?

I want to do a bit of colocation, and eventhough I can pay my way out of this I might be able to save a lot each month by doing it my self.
I want to be able to get a graph of the monthly BW up/down for each IP, and it could be nice to be able to se how much of my 100mbit line the servers use.
It should be reliable so it would not be a weak point in the network and easy to use.

What are the smaller shops doing for switch redundancy? We have all our machines on dual Com Ed feeds but most switches in the $1k-$3k range only have one power supply. We recently had a power strip go flakey and of course the switch was plugged into it.
Is the best solution getting two switches and hooking each machine up to both? How hard is that to setup in Linux? I've used keepalived for whole machine failover but not for network failover.
