For most users, you probably have a large collection of vSphere license keys that have been provisioned over the years and keeping track of the product SKU, entitled features and capacity can be a challenge, especially if you are just looking at the raw 25 character license string.
While the Broadcom Support Portal (BSP) is recommended for all license management operations(view, split, merge, etc), did you know you could also use vCenter Server to help decode a particular license key?
