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.
I just recently installed RTG to poll my switch.
I am trying to figure out how to reset RTG per port so that it would poll data from the beginning.
Example: I only want to restart the polling on port1, how would I reset the RTG to do so?
i was wondering in this picture it displays green and blue color but the question is which colors is downloads and uploads?

The memory usage on my server has slowly been creeping up over the last few weeks due to increased load. Here is my munin memory usage graph for the last week:
[url]
Could someone tell me what I need to be looking for or how to interpret this?
The cache and buffers have been getting really high but also has the inactive memory… so its looks as though its using memory and marking it as inactive afterwards and although graph shows I have massive memory use at first glace it also shows I have half my ram inactive and therefore available to be used.
why mrtg screws graphs up if bandwidth usage goes over 120 mbit/sec? See an attachment. First graph from mrtg, second one provider's graph which is correct. In mrtg.cfg I got MaxBytes[_]: 2250000000

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?
We have 1 Gb/s channel. We want connect it to switch, than to two routers (first - main, and second - emergency, which will began work if first one dies).

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).
For those who have used 10G switches...which model/vendor would you recommend and why?
View 14 Replies View RelatedI 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.

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?
Requirements:
My budget: $4 per month
Space needed: 1GB+
Traffic: 20GB per month
PayPal payment only.
Multiple domain hosting.
CPanel.
And reliable at long last!
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,
View 2 Replies View RelatedDoes 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?
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.
I'm just getting into the world that is colo.
I'm going to be setting up 2 machines in my cabinet shortly, neither one having very much traffic at all (maybe 4000 visitors - 100GB traffic - per month between them).
Once they are setup, I plan to move 2 more into the cabinet, which I'm currently leasing at another Data Center. These two are higher volume (unsure as far as the number of visitors) but I would guess about 20GB of daily transfer (spiking at about 6.0 Mbps occasionally) between the two of them.
The next piece of the puzzle that I need to figure out, is what switch to purchase (and ultimately why). My plan was to use just a 16 port D-Link to begin with, but I'm unsure as to whether or not this will be insufficient.
Switch And Data, a provider of network neutral data centers and colocation services, just had an IPO yesterday. They filed to sell about 1/3 of their shares priced at the high end ($17). I was wondering if anyone here had personal experience with the company, and could offer some insight on how they stack up versus Equinix and other competitors.
Switch And Data trading symbol: SDXC
Equinix trading symbol: EQIX
Equinix has been up a lot this year and has a huge market cap of 2.3Bil ($80/share), with revenues of 269Mil, gross profit 63.7Mil, net income -49Mil.
I calculated Switch And Data has around 35.9 million total shares, which puts its current market cap at around 720Mil ($20/share). I couldn't find any 2006 numbers, but in 2005 they had 105Mil revenues and -11.3Mil net income.
How comparable are these two companies? Does SDXC deserve to trade at a comparable level to EQIX? What do the experts at WHT think?
Where can I purchase a Cisco switch in Chicago? (2960G-24, to be specific)

Ok, I have a ProCurve 2900 switch. At the moment, all my servers are just connected to it, no vlans are configured on the switch since I am not selling any dedicated servers.
So I just connect my devices to the switch and configure them with one of the free IPs available.
But, when I run a traceroute, I dont see the switch. Not really an issue that I am concerned about, but I'm more curious than anything.
I am planning to get 2 uplinks for a cluster of servers. So, there will be 2 different
IP subnets and 2 different uplinks. I want the switch:
1. To be able to switch providers when any one of them is down
2. To be able to load balance the traffic (optional)
Also, I prefer to use Cisco.
