|
|
<div><p>With the best possible mirrored protection configuration, the system continues
|
|
to run after a single disk-related hardware failure. On some system units,
|
|
the failed hardware can sometimes be repaired or replaced without having to
|
|
turn off the system. If the failing component is one that cannot be repaired
|
|
while the system is running, such as a bus or an I/O processor, the system typically
|
|
continues to run after the failure. Maintenance can be deferred, the system
|
|
can be shut down normally, and a long recovery time can be avoided.</p>
|
|
<p>Even if your system is not a large one, mirrored protection can provide
|
|
valuable protection. A disk or disk-related hardware failure on an unprotected
|
|
system leaves your system unusable for several hours. The actual time depends
|
|
on the kind of failure, the amount of disk storage, your backup strategy,
|
|
the speed of your tape unit, and the type and amount of processing the system
|
|
performs. If you or your enterprise cannot tolerate this loss of availability,
|
|
you should consider mirrored protection for your system, regardless of your
|
|
system's size.</p>
