EOS

EOS is a disk-based, low-latency storage service, developed at CERN, and in principle the successor of AFS.

Official documentation: https://eos-web.web.cern.ch/eos-web/

Support service: https://cern.service-now.com/service-portal?id=service_element&name=eos-service

Introduction

The main target area for the service is physics data analysis, which is characterised by many concurrent users, a significant fraction of random data access and a large file-open rate.

Install with locmap

$ locmap --enable eos
$ locmap --configure eos

Access EOS

$ ls /eos/

As EOS is meant to replace AFS at some point, all CERN registered users get an EOS home. You can access this "home" folder in interactive systems such as lxplus, although it is not yet set to be the home folder.

An example for user dabadaba:

$ /eos/home-d/dabadaba/
