Here is a related post from stackoverflow. You need to use function call like the following to set interface name or IP address. curl_setopt($curlh, CURLOPT_INTERFACE, "xxx.xxx.xxx.xxx");

Why do you want to use a different interface in each case? Unless you are benchmarking the interfaces and for some reason want to do that in php, then there is probably a better solution. libcurl does implement this sort of functionality, but I'm not sure about php's binding for it. If it's not there, you could just use the curl command directly via a ...

ESXi has no real direct construct for dealing with IB other than when it's emulating something else such as Ethernet or FC/SCSI, it just has these Ethernet/DCB switches. What I would do would be to leave the Ethernet drivers in place then user Direct I/O to pass control if the 3rd and 4th controllers to your VMs, that way the OSs inside the VMs can do what ...

You would probably need a professional meter that would measure all sorts parameters, as the strength of the signal is just one of them, and by all means not the most important. Noise and cross talk are examples of parameters I would personally look at. You can rent a professional Fluke meter for a reasonable price.

Ask your co-location facility or datacenter for their suggestions on how to approach this. If the bandwidth is really expected to require 10Gbps, you'll need to scale up your firewall and networking infrastructure to meet the need. So if that means a better firewall, it is what it is. Your budget option would be an open-source firewall built on commodity ...

Lights usually mean you have an electrical connection, they do not necessarily mean that the signal is getting through perfectly. You can have lights but still see such high packet-loss that communication is impossible. Imagine a phone call where you can reach the person you call, but their voice is scrambled with static. The 100 meter length is not a ...

You can use (good) Cat5e cables with length > 100 meters. They may not provide with full quality and speed, but may work. You can test the cable and measure the length with some (pro) cable testers like Fluke Networks CableIQ. Some switches can do this, too. The feature is called TDR (Time-Domain-Reflectometry). Lights should be on as soon as the cable ...
