## Introduction
|
|
|
|
The [Data Center Light](https://datacenterlight.ch) is our radical
|
|
different answer to challenges of the climate change and
|
|
centralisation.
|
|
|
|
It is located in Linthal and is part of the [Digital
|
|
Glarus](/u/projects/digital-glarus) projects.
|
|
|
|
## How Data Center Light came into existence
|
|
|
|
Originally ungleich used to be a Linux/Unix/network consultancy
|
|
company. Over the years, more and more customers asking us whether we
|
|
provide a space to store their data and to run their applications.
|
|
Until the end of 2014 we politely declined and referred our customers
|
|
to other data centers or hosting providers.
|
|
|
|
In 2015 however, we began to re-evaluate whether it is actually
|
|
feasible to build a data center in Glarus.
|
|
|
|
## The three components of a data center
|
|
|
|
If you consider to run a data center, there are three important
|
|
factors:
|
|
|
|
* space - where to put your servers?
|
|
* power - how to power your equipment?
|
|
* connectivity: how to be reachable from the Internet?
|
|
|
|
Our approach from the beginning was to avoid building new buildings,
|
|
because there are many empty buildings from the spinning and weaving
|
|
time here in Glarus.
|
|
|
|
After looking around a bit, we found a nice old house, the [Digital
|
|
Chalet](/u/projects/digital-chalet), which we started to modernise
|
|
immediately and prepare it for a data center prototype.!
|
|
|
|
The local power company, [TBGS](https://www.tbgs.ch/), a now long time
|
|
partner, offered us to help to get proper power connections into the
|
|
Digital Chalet.
|
|
|
|
And as luck turned out, TBGS was also able to provide us with a direct
|
|
fiber line. Later we learned that this was actually not so much of an
|
|
"accident", but something we could have seen coming:
|
|
|
|
The valley of Glarus was historically hosting spinning and weaving
|
|
companies, most of which used to have their own power plant. The power
|
|
plants are usually hydro power plants, supported by the river
|
|
[Linth](https://en.wikipedia.org/wiki/Linth). Nowadays, there are also
|
|
some solar polar plants.
|
|
|
|
Even after the spinning and weaving companies closed, the hydro prower
|
|
continue to run. As a grid provider, you need to measure the
|
|
production capacity to compensate the producers correctly. TBGS did a
|
|
smart move many, many years ago: instead of reading the data via a
|
|
slow copper line, they were smart and added fiber lines directly to
|
|
the power plants.
|
|
|
|
And this is the reason why we were easily able to also be connected to
|
|
the fiber backbone.
|
|
|
|
|
|
## The growth of Data Center Light
|
|
|
|
After our initial prototype in the Digital Chalet proved to be
|
|
working, we expanded to a bigger area in Linthal, the
|
|
[Linthpark](https://www.linthpark.ch/). This area hosts the historic
|
|
building of the **Spinnerei Linthal**, which are also modernised and
|
|
now provide us with space for running the Data Center Light.
|
|
|
|
|
|
## Why is named Data Center Light?
|
|
|
|
The "light" refers to avoiding resource heavy and unsustainable
|
|
components. We employ the following mechanisms to avoid wasting
|
|
resources:
|
|
|
|
* We only consume 100% renewable energy
|
|
* We don't rebuild, but use existing buildings
|
|
* We use modern, but used hardware where possible (not for disks/ssds
|
|
though)
|
|
* We don't cool our servers
|
|
|
|
## How does a data center work without cooling?
|
|
|
|
Instead of using high density racks and putting them next to each
|
|
other, we use the available space of the old factory
|
|
buildings. Instead of hosting 40 servers on one square meter, we host
|
|
one server on 4 square meters. We can do this, because factory halls
|
|
tend to be huge. And in Glarus, they are also available.
|
|
|
|
## Products based on Data Center Light
|
|
|
|
In the Data Center Light we offer
|
|
|
|
* [Virtual Machine Hosting](/u/products/virtual-machine-hosting)
|
|
* [IPv6 only Virtual Machine Hosting](/u/products/ipv6-only-hosting)
|
|
* [Data Storage](/u/products/data-storage/)

|
* [Colocation](/u/products/colocation/)
|
|
|
|
Our objective is to enable people world wide and locally. From easier
|
|
working to giving safety to being able to store your data sustainable.
