Poscribes - Hardware Update

Over the past several weeks/months I have been collecting together the components necessary to update and enhance the hardware supporting this and several other websites that I maintain from my home.

The original configuration in a self-hosted model was that of a single PC. This thankfully was replaced by better hardware a couple of years ago that could be best described as powerful desktops or low-grade, non-redundant, server equipment.

Well today I am pleased to announce that through a little begging, a little borrowing and a little scavenging I have established not only a redundant configuration in terms of multiple web servers but also a load-balanced and highly available configuration.

Here's a quick overview of the setup as it stands now.

As you can see there are now two web servers and two database servers. A little overkill for the current setup maybe; but enough room to grow for the foreseeable future too. Like I said earlier this is not the only website that I am hosting on this system but it is the one that currently draws the most attention and the most traffic.

Here are few pictures of the equipment in operation. Some of it is not the newest server technology but the systems run strong, offer RAID capability and in the case of the two newer servers redundant power also.

My next step will be to establish some kind of round-robin DNS setup that permits fail over, albeit slightly delayed between the two types of internet connectivity that I have.

Over the next week or so I hope to provide examples of how I have established the load-balancing and replication using the Microsoft Windows Operating System.

Yes, that's right I am using Windoze!

Why not Linux I hear you cry? It's the perfect LAMP configuration! This is true, but I wanted to try something a little, well unconventional by todays standards.

That said, in all likelihood upgrades or additional equipment will involve Linux, although I'm hearing good things about Windows 2008, so I'm gonna have to try it somewhere, maybe here!
