• Rates – Allocates system resources between the background activity
such as Rebuild, Media Patrol, Migration/Expansion, Initialization, and
Synchronization, and the data read/write activity.
A High setting assigns most of the system resources to background
processes. The process will finished sooner but read/write requests are
handled slower.
A Medium setting tries to balance system resources between the
background processes and data input/output activity.
A Low setting assigns most of the system resources to handling read/
write requests. Read/write requests are handled at nearly normal speed
while the background processes take longer.
• Automatic Rebuild Status – When enabled, and a hot spare drive is
available, a critical or degraded logical drive will rebuild itself
automatically.
