MANAGING THE WD SENTINEL SERVER (DASHBOARD)

WD SENTINEL DX4000
ADMINISTRATOR’S GUIDE
Storage Displays storage information associated with the WD Sentinel server. The
WD Sentinel server holds up to four of WD’s hard drives optimized for
quality, reliability and performance 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 degraded. (A failed drive must be replaced with a
healthy drive as soon as possible to fully protect your server and
data.)
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
immediately.
System Temperature Enclosure: The temperature within the server enclosure.
CPUs1&2: The 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 for each core.)
The status may be:
• Normal
• Warm
• Hot
Cooling Fans The status of the server’s cooling fan may be:
• Active
• Inactive
Speed of revolutions in RPMs.
Power Supplies
1&2
The server has two power supplies. If you use both and one fails, the
other takes over and the WD Sentinel server remains operational. The
status may be:
• Active
• Inactive
