What low-cost Gigabit Ethernet switch would you recommend for providing residential IP services to an apartment complex that is already prewired for copper Ethernet? My only real requirement is that is it a managed switch supporting QoS, capping, and has fiber uplinks.
View 9 RepliesCan anyone recommend a product that converts a DS3 to an Ethernet connection?

1. A NAS (e.g. Lacie or Thecus) with 1GB port connected to a gigabit switch
2. An external storage that uses USB 2.0 interface
3. An external storage that uses eSata inferface.
Assumption:
All of it use sata drives under a raid 5 configuration.
would you recommend some PCI with 2 or 4 Ethernet 10M ports?
View 1 Replies View RelatedSay I have my own office to start building out my own "mini" data center.
If I wanted a lot of bandwidth for the most reasonable cost, how do one go about buying bandwidth from various providers? What is Metro-Ethernet vs. say a DS3? I know there is Fractional DS3 (6 to 45mb/s) and then Ethernet services up to GigE. I'd rather not mess with BGP right now either.
If I am looking at 15-20mb/Sec of bandwidth, what would be a good route to go? My budget is about $1500/month for bandwidth and IP Addresses (I need 2 Full Class-C IP Spaces). I also want to be able to turn up speed as needed without a lot of hassle.
Is this a reasonable budget? And where would be a good place to start? Just call up like Level 3 or am I too small potatoes to even deal with?
I now have to move on to the question of Ethernet ports in relations to rack mount servers. I have just about ever question answered now. Now my question is about the connection to the web my server will use. Is it better to have a single or a dual Ethernet post?
I see a lot of duals. Here are some of the samples I have read when building my server.
2 x Intel® 82546GB Gigabit Ethernet Ports
Dual Onboard Gigabit Ethernet LAN Ports
Dual Intel® 82541GI Single-port Gigabit Ethernet Controller
Broadcom dual Gb NICs
Intel dual Gb NICs
Broadcom BCM5754, 10/100/1000Mbps
I don’t know which one to look at or get?
I have inbuilt Ethernet card RTL8139D , but when i install RHEL 4 or 5 , Fedora version the Ethernet card diver not installed or ethernet card not installed but when i install suse linux it working fine without any problem so can any one tell me how to install lan card on Fedora or RHEL5.I have driver in CD but it not working with it.

yesterday the dc tech logged-in by ssh (root) cause we couldn't connect to the ftp box we keep our backup's (the new box couldnt connect to the ftp got time out)
They fixed it.
Today i got a time out and after 2 reset and restaring of services the server was back again.Then i got this messages and it still coming (3 hours now i get 1 similar message per 5 second )

Also the firewall stopped the port scanning from a server within the same dc.
I checked it on google and the explanation's varies but most say that is a problem of the router/switch or similar.
Say a server has 2 gig-e ports on board, and the OS
is using both. Can I still use IPMI feature? Or do I have
to get an additional ethernet card?
We're ready to setup 3-4 42U racks for servers and are in need of choosing Ethernet switches. What do you guys use and why?
I'm looked at Cisco switches, but lost in their product forest. I'm looked at Express 500, 2960 and 3750-E models. Is there any more difference (in exception of stacking, cli and hot-swap fan/psu) that I need to consider? Prices differentiate too much.
I'm also looked at Linksys/D-Link business products and they seems to have the same features as Cisco Express series, but only 50% cheaper.
I've a rack in the datacentre, and actually sharing the ethernet line with another partner's rack.
Something like:
Bandwidth -> Switch 1 -> Switch 2 (partner's rack)
Bandwidth -> Switch 1 -> Switch 3 (my rack)
After a previous uplinks issue, i'm never able to hit above 4Mbps of download speed to my home's cable broadband anymore. I have no idea whether it's because my partner capped my bandwidth from Switch 1, or his usage has increased such that it's affecting my traffic too. I can't be too concerned about it with him, as he's paying the bulk of the bandwidth costs.
For the whole rack, i'm not able to hit above 5Mbps accumulatively, and my normal bandwidth usage is only about 1-2Mbps.
So i'm thinking of getting another line for bandwidth directly from the datacentre to my Switch 3, perhaps starting from just 1-2Mbps only.
How will things improve? Just a silly thought, whether my total available bandwidth can now be 5Mbps + 2Mbps = 7Mbps.
We have a few CPanel servers, all with multiple NIC's. (2 Each)
We want to setup Eth0 to be the managment interface (ie. 72.2.24.x)
We want to setup Eth1 to be the Shared / Exclusive IP Nic (ie. 67.69.141.x)
Here is the issue, Eth1 is on a totally different Vlan than Eth0.. thus, isolating DDOS attacks, and any other type of traffic concerns for managment.. But, it also has a different G/W as Eth0.
how to check ethernet connections in debian??
my server has 2 nics, how do I view them and their usage uptime etc in debian stable
I wanna see if they are being used randomly (usage on both), or if it hasn't been already setup and I need to do it (found a tutorial on how to do this, but dont' wanna fix it, if it ain't broken)
We are in the process of buying a server to co-locate
All the server centre's we look at are trying to charge lots of money for firewalls
We have looked into renting and buying firewalls
but all the bought ones seem to be in the form of 1U
my question is this:
Is it possible to have a firewall that fits inside a 1U rack?
...something like a network card with an inbuilt firewall
does any hardware like this exist or will we need something that takes up a 1u space?
how can I change ethernet port speed. For example I want to change 100 mbit to 20 mbit. I m using centos 4.5 final.
