The metadata is the companion data of the data itself. Generally smaller, it contains some important additional information, e.g. (time of last access, access rights, folder which file belongs to, etc).
In a standalone computer system, data and metadata are stored together on a file system on the locally attached hard disk. The metadata is stored generally in the inode of the file.
In a clustered storage system, the current trend is to store data in a storage exclusively dedicated to storage and to store metadata in another cluster dedicated to DB and indexing.
The question is: is it possible to store both metadata and data in the same cluster ?
