Cross-border concept

What is a cross-border Twin-Datacenter-Concept?

A cross-border Twin-Datacenter-Concept is a cross-border datacenter concept, whereby in two different countries a datacenter is located. These datacenters are connected by use of a dark fibre, due to this data-transport and back-up can be done realtime. Both locations have to be in a range of 10 kilometres.

Systemec's cross-border Twin-Datacenter-Concept

Systemec realized this concept by building a datacenter in the Netherlands and connecting this datacenter with the simultaneously build datacenter in Germany. Due to the location of the datacenters in Germany and the Netherlands the customers of Systemec can benefit from two independent power supply networks and make use of multiple international carriers, which at the end almost realizes 100% reliability of the datacenters.

The location in Venlo (NL) and Nettetal (D) make use of two separate power supply networks: Enexis(NL) and Stadtwerke Nettetal (D). Due to this their is a significant smaller chance that the power fails at both datacenters. Your data and applications will always be available due to this benefit.  

What happens if your primary location fails due to external influences?

By making a risk-analysis you determine your Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs).  These objectives are the basis of a plan, which includes a back-up and co-location. Co-location makes use of a minimum of two locations, such as the datacenter in Venlo (the Netherlands) and the datacenter in Nettetal (Germany), to keep the data and applications available.


RPO: how much data loss in time may occur? With a RPO of 4 hours it means that in the worst-case scenario 4 hours data loss will occur because the last back-up is from 4 hours before the failure. 

RTO: how much time may pass before the systems get operational again with the last back-up data (RPO)? A RTO of 2 hours means that the there are 2 hours needed to make the system ready for use with the data that is maximum 6 hours old (taking the 4 hours RPO).

By hosting the setting in 2 datacenters and by using redundant hardware (SAN) with for example VMware Site Recovery Manager, a direct switch without to the other datacenter can be done, when a failure occurs without losing any data, which results of a RTO and RPO value of almost 0.  

Other scenarios whereby a higher RTO and RPO are acceptable are also possible. A co-location can be designed with only back-up data without a complete mirroring of the hardware capacity. This cost effective solution has higher impact on the RTO value.
