vCenter Server 6.0 New Features

by Roger Lund

Today Announces the release of VMware’vCenter largest release in VMware History. Note. These facts are pre release, thus I will update any changes if necessary, All Facts are direct From VMware.

vCenter Server Features – Enhanced Capabilities

Hosts per VC
Powered-On VMs per VC
Hosts per Cluster
VMs per Cluster
Linked Mode

Platform Services Controller 

Platform Services Controller includes takes it beyond just Single Sign-On. It groups:

  • Single Sign-On (SSO)
  • Licensing
  • Certificate Authority
Two Deployment Models:
vCenter Server and Platform Services Controller in one virtual machine
– Recommended for small deployments where there is less then two SSO integrated solutions
vCenter Server and Platform Services Controller in their own virtual machines
– Recommended for most deployments where there are two or more SSO integrated solutions

Linked Mode Comparison

vSphere 5.5
vSphere 6.0
Single Inventory View
Single Inventory Search
Replication Technology
Microsoft ADAM
Roles & Permissions

Certificate Lifecycle Management for vCenter and ESXi

VMware Certificate Authority (VMCA)

Provisions each ESXi host, each vCenter Server and vCenter Server service with certificates that are signed by VMCA

VMware Endpoint Certificate Service (VECS)

Stores and Certs and Private Keys for vCenter Services

vCenter Server 6.0 – VMCA

Root CA

  • During installation, VMCA automatically creates a self-signed certificate
  • This is a CA certificate, capable of issuing other certificates
  • All solutions and endpoint certificates are created (and trusted) from this self-signed CA certificate

Issuer CA

  • Can replace the default self-signed CA certificate created during installation
  • Requires a CSR issued from VMCA to be used in an Enterprise/Commercial CA to generate a new Issuing Certificate
  • Requires replacement of all issued default certificates after implementation

Certificate Replacement Options for vCenter Server

VMCA Default

  • Default installed certificates
  • Self-signed VMCA CA certificate as Root
  • Possible to regenerate these on demand easily

VMCA Enterprise

  • Replace VMCA CA certificates with a new CA certificate from the Enterprise PKI
  • On removal of the old VMCA CA certificate, all old certificates must be regenerated


  • Disable VMCA as CA
  • Provision custom leaf certificates for each solution, user and endpoint
  • More complicated, for highly security conscious customers

Cross vSwitch vMotion

  • Transparent operation to the guest OS
  • Works across different types of virtual switches
  • vSS to vSS
  • vSS to vDS
  • vDS to vDS
  • Requires L2 network connectivity
  • Does not change the IP of the VM

  • SSO Domain
  • Same SSO domain to use the UI
  • Different SSO domain possible if using API
  • 250 Mbps network bandwidth per vMotion operation
  • L2 network connectivity on VM portgroups
  • IP addresses are not updated

  • MAC Addresses preserved across vCenters
  • Always unique within a vCenter
  • Not reused when VM leaves vCenter

Long Distance vMotion 

  • Cross-continental distances – up to 100ms RTTs
  • Maintain standard vMotion guarantees
  • Does not require VVOLs
  • Use Cases:
  • Permanent migrations
  • Disaster avoidance
  • Multi-site load balancing
  • Follow the sun

Increased vMotion Network Flexibility


  • vMotion network will cross L3 boundaries
  • vMotion can now use it’s own TCP/IP stack

Content Library Overview

Update: a post vSphere 6 – Clarifying the misinformation has been posted to clairify any changes that have or will happen between beta and this post. I did my best to validate that my information is correct.
