Technology Overview
Xserve RAID
Monitoring Xserve RAID Systems
Xserve RAID features robust self-monitoring technology that maximizes storage avail-
ability while minimizing the pressure on system administrators. RAID Admin software
reports at-a-glance information about all Xserve RAID systems on the network, with
green, yellow, or red icons indicating the health of each subsystem. Administrators can
easily “drill down” for detailed information about the status and performance of each
component. If operating conditions for any subsystem exceed predened thresholds,
RAID Admin can automatically notify the administrators via email, pager, or email-
capable cell phone—allowing them to stay in touch with storage deployments and
resolve issues without downtime or data loss.
RAID Admin software displays summary health and activity information for multiple
Xserve RAID systems.
File system journaling in Mac OS X Server
A robust le system journaling feature in
Mac OS X and Mac OS X Server enhances
the availability and fault resilience of
servers and server-attached storage devices.
Journaling protects the integrity of the
Mac OS Extended (HFS+) le system in the
event of an unplanned shutdown or power
failure and maximizes uptime by expediting
repairs to the aected volumes when the
system restarts.
