Introduction | en Introduction This manual covers the DVA-08K series of RAID subsystems. With its basic hardware redundancy and the capability of fast I/O transfer, the 2U RAID SATA subsystem is an ideal solution to meet the ever increasing demands for addition of storage capacity.
Each drive channel is routed to an enclosure drive tray that is equipped with a stan- dard SATA connector with of hot-swap capability. The methods used for assembling physical drives, fault management, and status monitoring are identical to that used with Bosch’s long line of RAID storage enclosures.
• Drive bays with drive tray canisters: The drive bays are used to house the subsystem hard drives. The DVA-08K contains 8 drive bays with a blank plate covering the lower part of the front panel. Bosch Security Systems...

RAID Subsystem DVA-08K | Installation Manual Subsystem Monitoring | en Audible Alarm Different subsystem environmental and operational parameters (i.e., temperature, etc.) have been assigned a range of values between which they can fluctuate. If either the upper or lower thresholds are exceeded, an audible alarm will automatically be triggered. The alarm will also be triggered when an active component of the subsystem fails.
| Subsystem Monitoring RAID Subsystem DVA-08K | Installation Manual NOTICE! If the temperature exceeds a preset threshold, the BBU charger circuits will stop charging. You will then receive a message that says “Thermal Shutdown/Enter Sleep Mode.” When the temperature falls back within normal range, the battery will resume charging.
