TYPES OF STORAGE PROVIDED BY OPENSTACK .
OpenStack supports two types of storage:
1. Persistent Storage or volume storage
2. Ephemeral Storage
Persistent Storage / Volume Storage: It is persistent which means it will be available at later stage when the instance is shut down and independent of any particular instance. This storage is created by users.
Types of Persistent Storage
- Object storage: It is used to access binary objects through the REST API.
- Block storage: This is the traditional type of storage which we also see in our general computer systems.
- Shared File System storage: It provides a set of services to manage multiple files together for storage.
Ephemeral Storage: It is a temporary that is disappeared once the VM is terminated.
