1.0Initial Version
2.0Uploaded newer version of workflow which is validated on UCS Director 5.2 release (Note: If workflow version 1.0 is already configured on UCS Director 5.1, it should work fine even after upgrading the UCS Director to 5.2)

Workflow Name:




This workflow provisions ESXi Host booting from SAN and Integrates with vCenter Server and Nexus 1000v DVSwitch on Vblock 3XX Converged Stack. Before provisioning the ESXi Host, this workflow checks the current RCM (Release Certification Matrix) score of the Vblock 3XX from VCE Vision IO and continues only if the RCM score is equal or greater than the defined score.
