Technology Overview
Mac OS X Server
High Availability
Computer problems such as unplanned shutdowns can severely impair an
organization’s operations. High availability of your computing resources is essential
to guarantee service levels, comply with industry regulations, and provide access to
business-critical information. Apple has built into Mac OS X Server powerful high-
availability features that maximize server uptime and reduce the risks of shutdowns.
These features include:
• Watchdog processes that continuously monitor activity and recover services in the
event of an application, system, or power failure
• IP failover to further increase service availability in the event of a failure on one server
• File system journaling to dramatically expedite le system repairs on system restarts
• Software RAID with disk mirroring to eliminate drive failures bringing down a server
• Disk space monitoring to access available drive space and, if necessary, proactively free
up space by deleting or backing up noncritical logs and utilities
