Serviceguard for Linux at a Glance
What is Serviceguard for Linux?
Chapter 1 21
Serviceguard is designed to work in conjunction with other high
availability products, such as disk arrays, which use various RAID levels
for data protection; and HP-supported uninterruptible power supplies
(UPS), such as HP PowerTrust, which eliminates failures related to
power outage. These products are highly recommended along with
Serviceguard to provide the greatest degree of availability.
