EOS Integration into OpenStack Manila

Elisabeth Petit - Bois

The purpose of this report is to provide a brief overview of what OpenStack is, focusing on the 
advantages of the integration of its Manila component at CERN. Furthermore, this document briefly 
describes the EOS file service, its history, and its potential to introduce a much more cohesive cloud 
environment for users by porting its services to OpenStack Manila.  
CERN currently uses OpenStack heavily, employing more than five of its components to perform 
authentication, manage virtual machines, and more. OpenStack Manila, a shared file service, is one 
of the newest additions to the organization’s deployments. OpenStack Manila allows for storage 
management and simultaneous file access. 
EOS, a file service, hosts more than 270 petabytes worth of experiment, project, and user data. 
Through services like CERNBox, users are able to access their files easily through the EOS file 
system. While users are able to quickly retrieve files, users lack the ability to flexibly manage their 
storage space. 
The scope of this project is to bridge the gap between services like CERNBox and OpenStack Manila 
through the EOS file system in order to build a much more efficient, user-friendly system. This report 
will analyze OpenStack Manila’s architecture and operations.  It will also provide detailed 
descriptions on how to navigate configuration of an OpenStack Manila installation using DevStack, a 
software meant to emulate a production OpenStack environment.
