In addition to Tier One connections, the colocation specialist will need to have peering arrangement’s at major exchange point’s like LINX. A peering point is where several ISP’s arrange to “meet up” to switch traffic between each other in lieu of pay for transit across someone else’s network. You might say they are “cutting out the middleman! ” This but not only improves redundancy but additionally reduces latency; people will be able to access the websites and content hosted on your colocated server much faster if you ever colo host is well peered.

Quite often a web host or Colocation ISP might negotiate many peering arrangements with other ISP’s using whom they are exchanging a whole lot of traffic. Not only does this give them more resilience, but in addition, it reduces their own transit costs while using the Tier One providers enabling these phones offer more competitive info transfer pricing.

Latency is particularly important in regards to game server hosting together with colocation. Quite often an ISP specialising in games hosting will give you an IP address that you test ping times and carry out traceroutes.

Hardware Choices

Server housing costs in London or The big apple can be expensive. Not suprisingly your hardware should be “rack optimized. ” Colocation is normally priced “per U. ” A “U” is 1. 75 inches (or 4. 44 cms). Which means that rack servers, unlike desktop machines are long and flat. Data Centre’s also employ different types Rack Cabinets which are generally 42U in height, enough to house 42 1U servers though some of this space is used to accommodate switches, cabling. Often some space is left free to allow for efficient air distribution inside cabinet.

It’s often worth liasing with all your colo specialists over the selection of the physical hardware and especially the situation and rack mounting. The colocation specialist can know which brands work within their racks. Personally I get Dell Rack Optimized Machines and rail kits that quickest and easiest to help rail up.

So you’ve decided on the hardware, therefore you are about to ship your server on the remote colocation data middle. Bear in mind ones server will shortly be hundreds of miles away, indeed if you’re in the USA, it might even end up few hours flight away so there are a few technical points to consider prior to the machine is boxed, transported and colocated.

OpenSSH is shipped with all the main Linux distributions. You might wish to consider configuring SSH (usually done in /etc/sshd/sshd_config) to cooperate with Protocol2 only, disable root logins (or even only allow public key exchanges while using the `without-password` option) and turn off X11 forwarding as this is not required on a production server.

Several servers have multiple ethernet connectors, so it an be helpful, if you may not be using the second interface to either mask it off with tape or label the correct ethernet device.

Setup a Serial Console

This is certainly sometimes called “out with band” management. Quite often a colocation provider will possess a serial terminal on online site. This is basically some sort of server itself but with loads of serial ports.
