Getting to Know Your WD Sentinel DX4200 Server
Congratulations on your purchase of the WD Sentinel DX4200 Windows Storage Server.
Your WD Sentinel DX4200 device delivers a reliable, easy-to-deploy and manage storage
server designed for small business or workgroup environments. The
WD Sentinel DX4200 Storage Server provides secure centralized storage and seamlessly
integrates within almost any existing infrastructure.
Your WD Sentinel DX4200 features an easy-to-use WD StorCentral Dashboard, hard drives
optimized for reliability, quality, and performance, an Intel Atom dual-core processor, and
Windows Storage Server 2012 R2 Workgroup.
Key Features
WD StorCentral Dashboard
The WD Sentinel DX4200’s proprietary dashboard includes easy-to-use task wizards for
initial set up and common management tasks like storage configuration. It also provides an
at-a-glance summary of the system status, and manages networking, alerts, registration,
software updates, performance, and health monitoring.
WD enterprise-class hard drives
Equipped with WD Se hard drives that feature high capacity storage, peak performance and
24/7 datacenter-caliber reliability.
Seamless Integration
The WD Sentinel DX4200 easily integrates into workgroups, Active Directory, and most other
environments. Within the Active Directory environment, Microsoft’s Server Manager offers a
single view of all servers joined to the domain.
Security
WD Sentinel DX4200 has multiple layers of security. Beginning with physical security, the
WD Sentinel DX4200 has a bezel lock to prevent hard drives from being removed from the
system. It also includes a Kensington-style lock slot to secure the DX4200 to a desk. Upon
power up, the BIOS creates a secure UEFI boot environment. This prevents unauthorized
access to your company data by preventing booting from root kits. The Windows Storage
Server 2012 R2 Workgroup also contains layers of security. The WD Sentinel DX4200 can
manage users locally with multiple levels of access, and can be fully integrated into and
existing Active Directory.

PRODUCT OVERVIEW
Windows Storage Spaces
With Windows Storage Spaces, you can create large storage spaces and add more drives
to them when you run low on pool capacity. With the minimum of at least two WD-populated
drives, you can have two or more drives in the storage pool (data parity) and create storage
spaces that won’t be affected in the event of a drive failure.
Pre-installed Boot Drive
WD Sentinel DX4200 comes with one 2.5 inch boot drive pre-installed with
Windows Storage Server 2012 R2 Workgroup and specialized hardware services and
drivers. The pre-installed boot drive provides the ability to keep the OS running from the
boot drive while redeploying or changing applications and running folders on the large
capacity data drives. This allows businesses to save deployment time, as there is no need to
install from a DVD or search for any specialized drivers to install online. The
WD Sentinel DX4200 comes with the option to add a second boot drive with RAID 1 data
redundancy.
Redundant power capabilities
WD Sentinel DX4200 offers dual power supply ports, so in the event of a power surge or
other failure damage to the 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.
Dual Gigabit Ethernet Ports
WD Sentinel DX4200 comes with two Ethernet ports that can be configured for fault
tolerance, aggregated for high performance, or used for two separate LANs.
A Total Solution with Industry-Leading Technology Partners
The WD Sentinel DX4200 combines hardware and software from industry leaders to deliver
a reliable, secure, and easy-to-manage storage server designed specifically for
medium-sized businesses to small enterprise environments. WD Sentinel DX4200 features:
Unified Storage - The WD Sentinel DX4200 delivers an ultra-compact and quiet unified
storage solution with NAS functionality for file sharing and iSCSI SAN for block level storage
for virtualized environments.
Intel®Atom®processor – Built with an Atom dual core processor inside, with 4 GB
ECC RAM expandable to 16 GB RAM, the WD Sentinel DX4200 can easily handle your
business’s computing and file storage demands.
Windows®Storage Server 2012 R2 Workgroup – The dependable Microsoft
Windows Storage Server 2012 R2 Workgroup operating system provides the cost effective,
reliable, and easy-to deploy and manage storage solution your business needs to quickly
and efficiently organize, protect, and share your critical business data using the familiar

Shutting Down and Rebooting the Server
The WD Sentinel server is intended to be on at all times, providing shared data. A best
practice is to avoid turning the unit off. However, if it does become necessary (for example,
moving the server to a different location or performing a software update), follow the
procedures below to shut down or restart the server.
It is very important that the WD Sentinel server be shut down or restarted in a clean and
graceful manner through the Windows Settings function.
WARNING! To avoid a potentially unclean shutdown that could corrupt the
configuration, shut down the server through Windows Settings.
To shut down or restart the WD Sentinel device (Preferred method):
1. On the Windows desktop, move your mouse to the lower right-hand corner of the
screen and click the Settings button.
2. Click Power, then select Shut down or Restart.
3. From the pull-down menu, select a reason for your shut down or restart, then click
Continue.

MANAGING STORAGE ON THE WD SENTINEL SERVER
Managing Storage on the WD Sentinel Server
Storage Spaces
Setting Up Your Drives
Recovering from a Failed Drive
Storage Spaces
Storage Spaces is a Windows storage virtualization technology which succeeds Logical
Disk Manager and allows for the organization of physical disks into logical volumes similar to
Logical Volume Manager (Linux) or RAID levels 0, 1, 5, and 10, but at a higher abstraction
level.
A Storage Space behaves like a physical disk to the user, with optional thin provisioning. The
spaces are organized within a storage pool, i.e. a collection of physical disks, that can span
multiple disks of different sizes, performance or technology (USB, SATA). The same storage
pool can host multiple storage spaces. Storage Spaces have built-in resiliency from disk
failures, which is achieved by either disk mirroring or striping with parity across the physical
disks.
Setting Up Your Drives
Follow the steps outlined by in the Microsoft Storage Server Online Help to configure and
setup Storage Spaces on your WD Sentinel device.
Recovering from a Failed Drive
The WD Sentinel server lets you know when a drive fails in the following ways:
The LED above the bad drive is solid red.
The Power LED on the WD Sentinel server flashes red, indicating a serious fault.
An email Alert is posted if you have set it up to do so. (See “Setup Email Alerts” on
page 29.)
To recover from a failed drive:
1. Replace the drive (the one with the red LED over the drive) with an approved drive for
the WD Sentinel server (See “To view a list of compatible drives for your device:”on
page 30.)
2. Once replaced, follow the steps outlined by in the Microsoft Storage Server Online
Help to configure the WD Sentinel device using Storage Spaces.

BEST PRACTICES
Best Practices
Setting up the WD Sentinel Server
Using the WD Sentinel Server Efficiently
Replacing Drives
Shutting Down
The following practices help you use the WD Sentinel server and protect your data efficiently
and safely.
Setting up the WD Sentinel Server
Change the default name of WD Sentinel to something unique. This avoids
conflicts when another WD Sentinel server is added to your network in the future.
Make sure Ethernet 1 and Ethernet 2 are on the same network subnet.
Add the server to your domain. This allows users to use the same login and
password.
Make sure the password is stored in a safe place.
Set user password policy to at least medium security.
Enable Microsoft Automatic Updates to find and apply the latest Microsoft
software update.
Enable WD Automatic Updates to find and apply the latest WD software update.
Set up Automatic Alert Notification for real-time notifications of any problems with
the WD Sentinel server.
Do not remove the Windows page file! Some critical functions use the
system’s paging file. Removing the page file can potentially leave your system
unusable with the possibility of data loss. To maintain the reliability of your system
and its redundant resources, do not modify the paging file whatsoever.
Using the WD Sentinel Server 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.
Always use the WD Sentinel device with a UPS.
Enable email alerts. Receiving your alerts by email allows you to monitor certain
server issues as they occur.
Replacing Drives
When a data drive is removed, Storage Spaces will be degraded if another data
drive fails or is removed. Only remove one drive at a time between rebuilds. Once a
failed drive is replaced, manually rebuild the drive using Server Manager.
Avoid pulling a drive out unless there is a failure.
When a data drive needs replacement, the WD Sentinel server is still functional but
is subject to a second drive failure that would result in the loss of data. To minimize
this vulnerable time, a good practice is to have another drive ready to replace the
failed drive.

Shutting Down
Unclean shutdowns are hard on your system. To assure that the unit always
experiences clean shutdowns and the best data integrity, use an Uninterruptible
Power Supply (UPS).
To avoid possible corruption, do not unplug the power from the unit while it is
running.
