Question
What are the storage types allowed by OpenStack compute?
Answers
OpenStack supports two types of storage:
1. Persistent Storage or volume storage
2. Ephemeral Storage
Persistent Storage / Volume Storage: It is persistent and independent of any particular instance. This storage is created by users. There are three types of persistent storage:

Object storage: It is used to access binary objects through the REST API.
Block storage: It offers access-to-block storage devices by affixing volumes their current VM instances.
Shared File System storage: It provides a set of services to manage multiple files together for storage and exchange with multiple users at one time.
Ephemeral Storage: The ephemeral storage specifies a single instance. It is a temporary and short-lived storage that is disappeared once the VM is terminated.   Your Comment
