Built-in Active Directory and Primary Domain Controller: Small businesses need to
keep their data secure and must be able to restrict user access to it. The Active Directory
and Primary Domain Controller in the WD Sentinel DS5100/DS6100 provide centralized
management and security by authenticating and authorizing all users and computers on the
network. It assigns and enforces security policies for all computers, so when a user logs into
a computer that is part of a Windows domain, Active Directory checks the submitted
password and determines what data the user is able to access.
All inclusive data protection for small business: We combined hardware and software
from industry leaders to deliver a reliable, secure and easy-to-manage all-in-one server
designed specifically for small office environments. The WD Sentinel DS5100/DS6100
features:
Pre-configured Datacenter-class hard drives optimized for performance, quality and
reliability.
Protect your data on the 3.5” WD hard drives with either RAID (0, 1, 5, 10) or Windows
Storage Spaces depending on user set up.
Built with an Intel Xeon processor inside, WD Sentinel DS5100/DS6100 keeps your
business running smoothly with server-class features that help protect critical business
data with redundant storage capabilities and allows quick recovery in the event of a
failure.

Server 2012 R2 Essentials provides a powerful and flexible solution that helps protect
your business data while allowing you to access the information you need from virtually
anywhere with almost any device. It provides easier setup, installation and migration
experiences, a simplified management experience and better network-wide security
features. It also incorporates the latest Microsoft technologies for management,
networking, data storage and backup, and provides integration capabilities for cloud-
based applications and services.

Virtualize WD Sentinel storage using iSCSI Target: WD Sentinel DS5100/DS6100
supports iSCSI. IT Pro’s and advanced users have the ability to partition their WD Sentinel
for both NAS File based storage as well as IP-SAN with the iSCSI Target. This capability
enables the administrator to create multiple iSCSI targets to meet the specific needs of their
dynamic IT environments.
Enterprise-grade backup and restore software: The backup and restore software
included with the WD Sentinel DS5100/DS6100 saves time and space by performing a full
Bare Metal backup the first time and then, through block-level deduplication, backs up only
the data that has changed since the previous backup. In the event of a data loss or a drive
failure on a client computer, the WD Sentinel DS5100/DS6100’s fast and easy restore
function finds your files or lets you restore an entire system to get you up and running again.
Local and remote automatic backup and restore is supported for both Windows and
Mac OS®clients.
Pre-loaded Boot Drive(s): WD Sentinel DS5100/DS6100 comes with the 2.5-inch boot
drive(s) pre-loaded with Windows Server 2012 R2 Essentials and specialized hardware
services and drivers. The pre-loaded boot drive(s) provides the ability to keep the OS
running from the boot drive while redeploying or changing applications and folders running
on the large capacity data drives. This allows small businesses to save time, as there is no
need to install from a DVD or search for any specialized drivers to install online.
Flexible Capacity: WD Sentinel DS5100/DS6100 offers various storage capacities so you
can choose the capacity option that’s right for your business. It is also designed to be user
serviceable, with the ability to buy 2 TB, 3 TB and 4 TB expansion/replacement kits and

ports that can be configured for fault tolerance, aggregated for high performance, or used
for two separate LANs.

event of a power surge or other failure damage to the internal power supply, the second
power supply will take over, providing small businesses with the added peace of mind
knowing that their server will remain operational.
Choice of Disaster Recovery Options: WD Sentinel DS5100/DS6100 offers a choice of
disaster recovery protection options providing small businesses with the peace of mind that
their business data is secure. They can choose to protect their data using local disaster
recovery through network share (LAN & WAN) or local disaster recovery through DAS.
