|
||
|
|
<div><p>Mirrored protection is beneficial if you
|
||
|
|
have a multibus server or a server with a large single bus. A greater number
|
||
|
|
of disk units provides more opportunity for failure and increased recovery
|
||
|
|
time. Mirrored protection is local to a single server and is distinct from
|
||
|
|
cross-site mirroring or geographic mirroring. Mirrored protection works to
|
||
|
|
prevent outage on the server by keeping a second copy of the data on a mirrored
|
||
|
|
disk unit. If one disk unit fails, the server relies on the mirrored disk
|
||
|
|
unit.</p>
