Manila System Architecture

The Shared File Systems service is intended to be ran on one or more nodes.

Manila uses a sql-based central database that is shared by all manila services in the system. The amount and depth of the data fits into a sql database quite well. For small deployments this seems like an optimal solution. For larger deployments, and especially if security is a concern, manila will be moving towards multiple data stores with some kind of aggregation system.

Components

Below you will a brief explanation of the different components.

< REST >
  • DB: sql database for data storage. Used by all components (LINKS NOT SHOWN)
  • Web Dashboard: external component that talks to the api. Beta extended Horizon available here: https://github.com/NetApp/horizon/tree/manila
  • manila-api
  • Auth Manager: component responsible for users/projects/and roles. Can backend to DB or LDAP. This is not a separate binary, but rather a python class that is used by most components in the system.
  • manila-scheduler
  • manila-share

Further Challenges

  • More efficient share/snapshot size calculation
  • Create a notion of "attached" shares with automation of mount operations
  • Allow admin-created share-servers and share-networks to be used by multiple tenants
  • Support creation of new subnets for share servers (to connect VLANs with VXLAN/GRE/etc)
  • Gateway mediated networking model with NFS-Ganesha
  • Add support for more backends
