Should I use Bianca or Rackham?
Q: I want to analyse my data. How do I know whether I can use Rackham/Crex or if it's considered too "sensitive" and should be placed on Bianca/Castor?
A: The short answer is that no human data should be placed on Rackham/Crex.
The slightly longer answer is that any genetic data that is taken from individuals (i.e. not reference genomes) is sensitive data regardless of how "anonymised" it is. Read the relevant pages at VR and DataInspektionen. You must apply for a SNIC SENS project if your research involves sensitive personal data — applications to other resources will be denied.
The security of Rackham is that of any ordinary cluster. It relies on ordinary Linux mechanisms, which should be seen not as security, but rather as tools that enable many people to share a common resource with a minimum of incidents. Compare the function of a simple fence that keeps honest people honest (Rackham) and a brick wall with a security door (Bianca).
