What is the relationship between a storage volume and an extent?

In VPLEX, a storage volume is a logical representation of physical storage, and it can be divided into multiple extents.An extent is a contiguous range of block addresses within a storage volume that VPLEX manages as a single unit1.

Storage Volume: This is the physical storage presented to VPLEX from the backend storage arrays.It represents the total capacity available for use in VPLEX1.

Extent: An extent is a subset of a storage volume.It is a logical division within a storage volume that VPLEX uses to create virtual volumes1.

Division into Extents: A storage volume can be split into multiple extents, allowing for more granular management of storage resources.This is useful for creating multiple virtual volumes from a single storage volume1.

Virtual Volume Creation: Extents are used by VPLEX to create virtual volumes.By splitting a storage volume into extents, VPLEX can combine extents from different storage volumes to create a virtual volume1.

Management Flexibility: The ability to split a storage volume into multiple extents provides flexibility in storage management, enabling VPLEX to optimize storage utilization and performance1.

By splitting a storage volume into multiple extents, VPLEX can efficiently manage and allocate storage resources, creating virtual volumes that meet the specific needs of applications and workloads.
