VM-Storage¶

Setup¶

Minimal¶

• 1 VM-Storage in M-Web
• Identification of the storage server with HOSTNAME
• The storage is mounted per samba on VM-Processing in ./storage/

Optimal¶

• 1 VM-Storage in each M-Processing
• Identification of the storage server with URL and HOSTNAME
• The storage is mounted per samba on all VM-Processing in ./storage/
• Dynamic connection of one instance of VM-Storage to one M-Web
  • As soon as a user starts an upload, he will be associated with the current M-Web by a session variable
  • As long as there are files in ./storage/temporary/, VM-Storage is pinned to M-Web
  • Nginx on VM-Nginx forwards the URL to the upload API directly to one instance of VM-Web on the associated M-Web
  • A script takes care of the load balancing of all instances of VM-Storage
• Authentification
  • User: Cookie (all VM-Web have to synchronize their cookies)

Services¶

• Samba server
