Settings Description
Network Health Displays the status (Connected or Not connected) of the server's network
Ethernet 1 & 2 connection(s). If you use both Ethernet ports and one fails, the other takes
over so that the WD Sentinel remains operational over the network.
Storage The WD Sentinel holds up to four of WD's enterprise-class drives and
features RAID levels 1 or 5 to enhance performance and data protection.
RAID is an acronym for Redundant Array of Independent Disks. With two
drives installed, the WD Sentinel server uses RAID 1 (mirror). With three or
four drives installed, the server uses RAID 5, which offers fast performance
by striping data across all drives. This arrangement protects data by
dedicating a quarter of each drive to fault tolerance, leaving three quarters
of the system capacity available for data storage.
Type: RAID level
Total capacity: Maximum amount of storage space (TB) available
Available capacity: Amount of storage (TB) left available for use
Alert Threshold: The percentage of storage capacity used above which
you receive alert notifications that the storage is approaching maximum
threshold.
Status: The status of the server storage may be:
• Healthy–All drives are in the optimal state.
• Degraded–A single drive failed; data is protected, but performance is
Status of drives 1-4: The status of a drive may be:
• Normal
• Failed! Visit WD Store to replace.
• CAUTION: Imminent failure detected. Please replace this hard drive
System temperature Enclosure: Temperature within the server enclosure.
CPUs 1 & 2: Temperature, status, and status description for each CPU.
(The server does not have two physical CPUs but instead uses a dual core
CPU. CPU 1 and CPU 2 represent the details of each core.)
The status may be:
• Normal
• Warm
• Hot
Fan The status of the server's cooling fan may be:
• Active
• Inactive
Speed of revolutions in RPMs.
Power Supplies The server has two power supplies. If you use both and one fails, the other
1 & 2 takes over and the WD Sentinel server remains operational. The status may
be:
• Active
• Inactive
