The only thing more important than having advanced computing services is having them available. Built into Mac OS X Server are powerful high-availability features that reduce the risk of unplanned shutdowns and maximise server uptime — so a company can confidently maintain levels of service, comply with industry regulations, and provide organisational access to business-critical information.
Watchdog.
For maximum availability, Mac OS X Server includes a watchdog process that continuously monitors activity and recovers services in the event of an application, system, or power failure.
IP failover.
When Mac OS X Server is used with two servers, the IP failover service further increases availability. If one server fails, the second server can take over the IP address and deliver services for the failed server.
Automatic restart.
Mac OS X Server can be set to restart automatically in case of a power failure or catastrophic system failure.
Disk mirroring.
RAID 1, or disk mirroring, is a common technique for eliminating single points of failure. Copies of the same data are mirrored on two or more drives — reducing the risk of service shutdown if one of the disks were to fail.
Disk space monitoring.
Running out of disk space can reduce the reliability of your server. Mac OS X Server includes tools that monitor disk space and proactively free up space by deleting or backing up noncritical logs and utilities.
