Take a Look at Dell’s Fortuna Server

As web traffic grows constantly and will continue to grow, I am always on the lookout for better ways to host a robust websites. Our clients always demand the best hosting solution but with an eye on the price. Currently the biggest price tags when it comes to hosting data centers is the power consumption and second is the actual space. Note that a side benefit to lower power consumption is reduction in the need of cooling, since logically increased power consumption means more generated heat.

In other words, to remain competitive hosting providers will strive to provide servers with lower power consumption and smaller form factors while assuming a certain level of processing power. This is exactly what DELL’s R&D is working on these days. Here is a video of what is in the works:

What is interesting is that the fortuna will supposedly place 12 of these mini servers in a single enclosure that fits in 2U space. This makes it a 1/6U server. 6 Servers per 1U of space. Here is a photo of a prototype:

Now, can you imagine each mini server hosting 2-4 VPS with CentOS serving the LAMP stack and either a Joomla, WordPress, or ZenCart on it? Nice!

How to Use Mod_Rewrite to Set a Canonical URL

The importance of the Canonical URL is well known in the SEO world. However, for most web developers and website owners is something that is often overlooked. The theory in short explains that search engines rank each page individually and typically penalize multiple pages with duplicate content. So, if a site does not have a mechanism that identifies a Canonical URL, (in other words, a unique URL for the main page), search engines may evaluate multiple links that result in the home page separately. As a result, your site may get penalized altogether or simply suffer from lower pagerank due to the fact that the pagerank is now shared among multiple pages. An example:

The home page of a site can be displayed with any one of the following URLs:

http://domainname.com

http://domainname.com/index.html

http://www.domainname.com

http://www.domainname.com/

etc.

To avoid the above, simply use apache’s mod_rewrite and include the following code in an .htaccess file that should be located at the root folder of the web server (replace the domain name text with your real one):
RewriteCond %{HTTP_HOST} !^www.domainname.com$ [NC]
RewriteRule ^(.*)$ http://www.
domainname.com/$1 [R=permanent,L]

Now, you’ll need to make sure that all your links that directs traffic to the home page use the chosen canonical url.
