Block Level De-duplication: WD Sentinel server features elegant block level
de-duplication technology for the computer backup data. A function completely transparent
to the users, it enables faster subsequent backups as well as efficient utilization of storage
on your server.
Active Directory Join: Active Directory join capability enables WD Sentinel DX4000 to
easily integrate into your existing infrastructure and networks.
DLNA Media Server: With the built-in DLNA media server your employees can access
WD Sentinel server's shared media library on the network rather than maintain copies of
media files on their individual computers. You can also stream digital content like videos,
music, or digital signage for employees, vendors, or clients using remote web access.
LCD Display Panel: The LCD display panel on the front of the device allows you to monitor
the system status and critical alerts.
Cross Platform File Sharing: WD Sentinel DX4000 supports industry standard protocols
such as CIFS/SMB and NFS, enabling file sharing across various Windows and non-
Windows clients.
Leading Edge Performance: With dual Gigabit Ethernet connectivity,
WD Sentinel DX4000 delivers read speeds greater than 85 MBps through the Gigabit
Ethernet interface. That is up to three times faster than most network drives in this category
today. For maximum flexibility there are also 2 SuperSpeed USB 3.0 ports to allow you to
connect additional storage devices and experience up to
5 Gb/s transfer rates.
Automatic RAID Migration and Capacity Expansion: Adding storage capacity to your
WD Sentinel server is as easy as changing a light bulb. Just open the door and add the hard
drive in one of the empty storage bays. WD Sentinel server does the rest. It seamlessly
migrates to the appropriate RAID level and automatically expands the server's storage
capacity. Your users can still access your business data while the new drive is being
integrated. No data loss. No downtime.

RAID edition drives.
