Space Storage Options and Persistence

ActiveSpaces provides several options for storing space data:

• RAM storage
• Storage on solid state drives
• Storage on magnetic disk

• RAM Storage
  ActiveSpaces data can be stored purely in RAM on machines running seeder processes. RAM is the fastest storage medium and provides the fastest reads and writes; however, it is the most ephemeral storage medium.
• Persistence Concepts
  To avoid possible data loss, you can persist data to physical media. ActiveSpaces allows you to persist data to disk storage and recover data if data loss occurs or there is a problem with cluster startup.
• Persistence Policy and Implementation
  For both types of persistence, you can specify that the persistence is maintained synchronously or asynchronously.
