In an existing VxBlock 1000 system, the compute servers are running VMware ESXi hypervisors.

When planning a compute expansion in an existing VxBlock 1000 system with servers repurposed from another VxBlock system, the required licensing includes VMware vSphere ESXi and Cisco 1000v licenses. These licenses ensure that the new compute resources are properly integrated and managed within the existing VxBlock environment.
