VMworld 2015: vSphere 6.0 in the Real World

Session INF4712

Compatibility Maximums – Review the document and stay within the guidelines.

vCenter 6 Platform choice: Windows and VCSA support same maximums and performance

  • Up to you, but look at things like Linux experience, licensing, existing skills, etc.

vCenter – New deployment architecture

  • PSC – SSO, License service, lookup service, vmdir, VMCA
  • vCenter – web client, inventory service, auto deploy, ESXi dump collector, syslog collector, etc.

PSC – Which architecture?

  • Embedded: Single site, no expansion past one vCenter
  • External: Supports up to 4 vCenters. HA mode is much more complex (3rd party load balancer)
  • Multiple sites – PSCs in each site, and replicate with each other.
  • Max size: 6 PSCs, 3 sites, 10 vCenters
  • Once a deployment model is chosen, you can’t change it in 6.0. U1 will allow changes.

VMware Certificate Authority – Favorite feature.

  • VMCA removes a lot of the certificate complexity
  • No longer uses self signed certificates
  • Built into the PSC
  • VMCA should you use it? Yes.
  • See KB 2111219 or my vSphere 6.0 install guide here

Standard vs. Distributed Switches

  • Always use VDS if you are licensed for it
  • Many of the past issues with VDS are now no longer an issue


  • Policy based storage management
  • Not all vSphere hardware is supported. Carefully check HCLs.
  • Learning curve for operational procedures and recovery
  • May require new hardware purchase

SMP Fault Tolerance

  • Long awaited SMP support (up to 4 vCPU)
  • Basically a continuous vMotion that only stops when there’s a hardware failure
  • 10Gb NIC requirement
  • Max 4 FT VMs per host

Content Library

  • New to vSphere 6.0
  • Storage for templates, appliances, ISOs, scripts, etc.
  • Should you use it? Definitely
