Explanation:

An OSD storage system is an object-based storage system that stores data as objects rather than files or blocks1.An OSD storage system consists of OSD nodes that have two key services: metadata service and storage service1.

The metadata service is responsible for generating the object ID from the contents of a file1. The object ID is a unique identifier that represents the data and its attributes.The metadata service also maintains the mapping of the object IDs and the file system namespace1. The file system namespace is a logical structure that organizes files into directories and subdirectories.

The storage service manages a set of disks on which the user data is stored1. The storage service stores data as objects in physical OSD containers. Each OSD container has a unique address that corresponds to an object ID. The storage service also handles requests from clients to read or write data to or from objects.
