In the event of component failure, a hard disk drive, power supply, battery module, RAID controller, or Reliability cooling fan can be replaced within seconds. The In addition to RAID protection against drive failure, the modules are closely monitored using self-diagnostic subsystem has ingenious means to deal with other features and the help of runtime utilities such as challenges that may jeopardize data integrity. For RAIDWatch. Spring screws, securing latches, and example, hard disk drives wear down over time and key-locks all provide easier access to the modules. drives may arrive from the manufacturer with inherent defects. Media Scan and Task Scheduler are among the A variety of configuration and monitoring methods are DrvSmart utilities designed for mending these available, either locally via the LCD keypad panel and problems. the text-mode RS-232C terminal, or remotely through the Java-based GUI manager. All faulty conditions, The subsystem is also equipped with error containment including RAID configuration events, module failure, algorithms, known as the SysSmart functions. If a voltage and temperature readings, are instantly critical component fails, e.g., a battery module, the reported. A system administrator can select from the subsystem automatically disables write-back caching following notification methods to receive reports when and assumes the conservative write-through mode.
