## 5.4.3 Working with and creating storage pools 

A managed disk (MDisk) is a logical unit (LU) of physical storage. MDisks are either arrays (RAID) from internal storage or LUs that are exported from external storage systems. Storage pools act as a container for MDisks by dividing the MDisks into extents. Storage pools provision the available capacity from the extents to volumes.
