Disk Usage
Disk Usage describes the total disk space occupied by system
Þles, by users, and by shares/volumes, the amount of free
disk space left, and the total available disk size of the
NASRaQÕs disks. This space is determined by the RAID
mode selected.
RAID
RAID status page describes four values relating to your
RAID disk conÞguration.
¥ RAID Mode - the RAID mode you decided to use when
you set the machine up in the setup wizard.
¥ Boot Disk- NASRaQ can boot from either of its internal
disks. This Þeld indicates the disk that the NASRaQ used
to boot from most recently.
The last two Þelds describe the operational status of each
hard disk.
If a disk has failed or has been removed from the system, the
ball next to the disk is red. The administrator also receives
mail from Active Monitor describing the problem.
Memory
Memory Status indicates if memory swapping is high. If you
see a red light, you may want to add more memory to the
NASRaQ.
CPU
CPU Usage provides a real-time update of CPU load. It
indicates the number of tasks waiting to be executed. This
chart helps you evaluate whether the NASRaQÕs CPU is
being used heavily or lightly.
