Serviceguard at a Glance
What is Serviceguard?
Chapter 1 29
• Mirrordisk/UX or Veritas Volume Manager, which provide disk
redundancy to eliminate single points of failure in the disk
subsystem;
• Event Monitoring Service (EMS), which lets you monitor and detect
failures that are not directly handled by Serviceguard;
• disk arrays, which use various RAID levels for data protection;
• HP-supported uninterruptible power supplies (UPS), such as HP
PowerTrust, which eliminates failures related to power outage.
HP recommends these products; in conjunction with Serviceguard they
provide the highest degree of availability.
