RE: Virtual console on iDrac 8
The Virtual Console is only available on the Enterprise version of the iDrac8. It is likely the other servers you're referring to are licensed to the Enterprise level, and this one is still at the Basic license.. You indeed would need to purchase that iDrac 8 Enterprise License to use the Virtual Console feature. If you contact your sales rep they will be able to get the license to you.
Let me know if this helps.
