Easy maintenance

Replacing one of the pre-installed drives is as easy as changing a lightbulb. Just open the door and swap out the drives. WD Sentinel does the rest. It seamlesslymigrates the server to the appropriate RAID level and automatically expands the server's storage capacity. Your users can still access theirbusiness data while the drive is being integrated. No data loss. No down time.

Comprehensive data protection for your entire office has never been easier.

    1. RAID: Featuring levels 1/5 for data protection and speed.
    1. Automatic backup and restore: The software saves time and space by performing a full backup the first time and then automatically backing up only the files that have changed since the previous backup. In the event of a drive failure, WD Sentinel's easy restore function finds your files, restores them to their previous location and gets you up and running again quickly.
    1. Dual Ethernet ports: Comes configured in Adaptive Fault Tolerance, which keeps your network available by automatically switching to the second Ethernet port if the first one should fail.
    1. Optional dual power supply: WD Sentinel DX4000 offers the small business owner the option of adding a second power supply that will take over should a power surge or other failure damage the first power supply. With the optional second power supply you have the added peace of mind knowing that your system will remain operational.
    1. Optional off-site disaster recovery protection:Choose the disaster recovery solution that works for your small business - local USB drive or backup to a cloud.
