MANAGING STORAGE ON THE WD SENTINEL SERVER 5 Managing Storage on the WD Sentinel Server WD Sentinel Server RAID Storage Using USB Storage Replacing a Failed Drive Adding Capacity by Adding a Drive WD Sentinel Server RAID Storage RAID is the acronym for Redundant Array of Independent Disks. The WD Sentinel server provides automatic RAID service to assure the integrity of the storage system. For redundancy, a minimum of two drives must be active.
MANAGING STORAGE ON THE WD SENTINEL SERVER to perform this operation. While the server is verifying the RAID array, your data continues to be available albeit the performance may be impacted. The WD Sentinel server RAID system has no downgrade options. Once available capacity has been increased, the Administrator cannot decide to subsequently reduce capacity by removing a drive. The removal of a drive degrades the RAID and makes it vulnerable to single drive failure.

BEST PRACTICES 7 Best Practices Setting up the WD Sentinel DX4000 Setting up Client Computers Using the WD Sentinel DX4000 Efficiently Replacing Drives Shutting Down The following practices help you use the WD Sentinel DX4000 and protect your data efficiently and safely. Setting up the WD Sentinel DX4000 Change the default name of WDSentinel to something unique to avoid conflict another WD Sentinel server is added to your network in the future.
BEST PRACTICES Using the WD Sentinel DX4000 Efficiently The WD Sentinel server has many jobs to perform. Share data during business hours, and back up the computers during hours of inactivity. Keep the server powered on 24/7 to do its work. Replacing Drives The online removal of a drive forces a rebuild when the drive is replaced. Until the rebuild is complete, the RAID system is degraded and susceptible to unrecoverable failure should another drive be removed.
BEST PRACTICES Shutting Down Unclean shutdowns are hard on RAIDed systems. The WD Sentinel server recognizes an unclean shut down and upon the reapplication of power, begins a long sequence of examining the RAID for errors and bringing the RAID configuration back into alignment. This sequence can take many hours. To avoid this situation and to assure that the unit always experiences clean shutdowns and the best data integrity, use an Uninterruptible Power Supply (UPS).
