===== System architecture =====

JASMIN is architected as a large data , small compute - a "Super Data Computer". It comprises a flexible mix of services including : 

  * 44Pbytes (Usable) high performance storage. A mix of 
    * Scale Out file. 
    * Traditional Parallel file. 
    * Flash File.
    * High performance object storage.
  * 80Pbytes Tape capacity.
  * Compute resources of around 20,000 cores split between
    * (An approximation to) A traditional HPC batch system. 
    * 2 OpenStack Clouds - both IaaS and PaaS in each. 
    * Traditional virtualisation. 
    * Container platforms.
  * Data transfer zone ("Science DMZ")

Utilising only a high performance low latency ethernet network for connectivity. The network uses a 5 Tier CLOS  Layer 3 Routed architecture.
