High availability services are important in any platform, and vCenter Server is no exception. As the main administrative and management tool of vSphere, it is a critical element that requires HA. vCenter Server HA (aka VCHA) delivers protection against software and hardware failures with excellent performance for common customer scenarios, as shown in this paper.

We thoroughly tested VCHA with a benchmark that simulates common vCenter Server activities in both regular and worst case scenarios. The result is solid data and a comprehensive performance characterization in terms of:

  • Performance of VCHA failover/recovery time objective (RTO)
  • Performance of enabling VCHA
  • VCHA overhead
  • Performance impact of vCenter Server statistics level
  • Performance impact of a private network
  • External Platform Services Controller (PSC) vs Embedded PSC

In addition to the performance study results, the paper describes the VCHA architecture and includes some useful performance best practices for getting the most from VCHA.
