# vCenter/ESXi registration or edit

Unisphere supports the discovery of vCenters or ESXi servers (using a read-only user) and integrates the information into Unisphere. VMware information is connected to its storage extents, and this information enables seamless investigation of any storage-related issues.

## About this task
