Key features of VMware HA include:

  • Proactive monitoring of all physical servers and virtual machines
  • Automatic detection of server failure
  • Rapid restart of virtual machines affected by server failure
  • Optimal placement of virtual machines after server failure
  • Scalable availability up to 32 nodes across multiple servers
