Explainer: What is RAID?

Reading about servers and storage you might have wondered: What is RAID? RAID is a method of melting multiple harddrives together to form a (often) larger logical drive. The acronym expands to either Redundant Array of Inexpensive Disks or Redundant Array of Independent Disks.

RAID was defined in a research paper: “A case for Redundant Arrays of Inexpensive Disks (RAID)” (Patterson et al, 1988). Andrew S Tanenbaum uses the latter acronym in his book (“Structured Computer Organization 5th Edition”, Tanenbaum, 2006, p 89). I had access to the 5th edition, from which I reference but you can get the 6th edition from Amazon.com and amazon.de (affiliate links).

Upgrading our home network with a Ubiquiti EdgeRouter X

Home network v. 1.0

In this post I will be upgrading our home network with the Ubiquiti EdgeRouter X. Our home network is due a very needed update as it is not running optimally. We have an reasonable internet connection through our local provider. It is a Fibre connection currently running at 100/100 Mbit/s. 

The Fibre is terminated at the provider’s router that is capable of providing both telephony and TV as well as Wi-Fi. We have not had a land line for years and decided when we were planning to move here that we would not sign up for Cable TV so both those are inactive. And as I wanted to have better control of my network I have asked the ISP to turn off the Wi-Fi as well.
