In the world of web hosting, there’s plenty of terms that get used without companies providing adequate definitions.  I wanted to take some time and share a few words with you about Redundancy.

Redundancy is in layman’s terms backup.  There are also several different types of redundancy: Network, Hardware, Power, and Geographic. A solid web hosting company will have multiple layers of Redundancy to ensure that your data is safe and to maximize your uptime.

Network Redundancy:

This backup is simply for the network a web hosting company uses to get you online.  Reliable proviers have multiple internet carriers that their servers use to ensure that your website never goes down.

Hardware Redundancy:

This backup is for the physical pieces of server hardware.   For instance one layer of redundancy is for the hard drives.  Here at Host Duplex, if a hard drive fails in our Dell PowerEdge servers, your site will not go offline, we have hot spares in place so our RAID arrays are immediately rebuilt.  We have a similar system for our sticks of RAM.

Power Redundancy:

These are the backups for the power that keeps your servers and data center running.  All of our servers have redundant power supply units.  Each PSU has a feed from a different utility company.  Each feed is also connected to it’s own UPS (uninterrupted power supply) which hold 3 hours of battery backup should the data center lose power, which is also connected to diesel generators should a power outage last longer than 3 hours.  So if an entire feed fails, including the feed’s UPS and generator, there is still a second feed from a separate electric provider with its own UPS and generator to keep your site online.

Geographic Redundancy

Finally there is geographic redundancy.  Host Duplex provides geographic redundancy services so that in the case of a complete datacenter failure, your site can be rerouted to a different datacenter.  I’m proud to say our data center is protected like Fort Knox and has enough redundancy to remain operational through natural disasters.  However, should the apocalypse take down our data center, Host Duplex offers services to have your site working non-stop in our Denver datacenter.

Hopefully this clears up any confusion or questions regarding Redundancy.  If you have further questions, feel free to comment, or shoot us an email directly.


Presenting at The University of Iowa John Pappajohn Entrepreneurial CenterI’m very pleased to report that our presentation at the University of Iowa Bedell Entrepreneurship Learning Laboratory (BELL) for student entrepreneurs went without a hitch.   My first reaction was that there was an excellent turnout, even though it was the Friday (April 2, 2010) before a holiday.  My second reaction was there was an abundance of Papa Johns Pizza!  A big thank you goes out to Lynn Allendorf of the John PappaJohn Entrepreneurial Center (JPEC) not only for lunch, but also for the amazing opportunity to share our experiences and knowledge with upcoming entrepreneurs who came to the BELL

We held some very interesting conversations with Jordan Tivers of Collegeinformant.com, Iowa City business owner Mokotsi Rukundo of The CorNroC, Golf Database, Hawk City Productions LLC, SMARTERX, and others.  We were very excited to hear of their successes.  I am convinced that our success can help our fellow entrepreneurs in the future and am very excited to continue relations with the rest of the Bedell entrepreneurs.

This opportunity was a great one to not only educate the students on what to look for when searching for the appropriate web hosting company, but to also offer our web hosting services.  I was very pleased to hear the entrepreneurs were interested in our Virtual Dedicated Servers.  I am confident that this first step will lead to a long lasting relationship with the many generations of University of Iowa Bedell student entrepreneurs to come.
