PRODUCT OVERVIEW  
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

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.

PRODUCT OVERVIEW  
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  
other parts.

ports that can be configured for fault tolerance, aggregated for high performance, or used  
for two separate LANs.  
Dual power supply: WD Sentinel DS5100/DS6100 offers dual power supplies, so in the  
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.

This chapter steps you though the process of connecting and setting up your  
WD Sentinel DS5100/DS6100 server and connecting it to computers in your network.  
User Roles and Responsibilities  
Types of WD Sentinel DS5100/DS6100 Users  
At a high level there are two categories of users who need to access one or more features of  
your WD Sentinel server.  
Administrator—This is the person who performs the setup and routine  
management tasks on the WD Sentinel server. This person is also the holder of the  
Administrator password of your WD Sentinel server.  
Users—You can have up to 25 user accounts on your WD Sentinel server. These  
can be:  
-
Internal Users – The internal users are typically the employees (including the  
Administrator) in your office, working locally or occasionally from a remote loca-  
tion (e.g. Sales Staff), who need to access business data and server resources.  
-
External Users – The external users are the customers and business  
partners with whom you need to exchange business data.  
The WD Sentinel server offers different paradigms for each type of user. The table below  
provides a view into the usage model and tasks for each category of users.

CONNECTING THE SERVER AND GETTING STARTED  
Connecting your Computers  
Once you’ve set up your WD Sentinel server, you can connect up to 50 Windows PCs or  
Mac computers to your device.  
Installing the Connector software joins the client computer to your WD Sentinel Server and  
installs Launchpad and Dashboard.  
Users use Launchpad to access server resources for which they have the rights.  
The Administrator (you) accesses Dashboard for such tasks as managing the  
WD Sentinel server, setting up user accounts, and managing access to shared  
folders.  
Important Steps  
Before installing Connector software on a computer, ensure that:  
The computers have all the latest mandatory and optional operating system  
updates installed.  
There are no active backups in progress on the WD Sentinel server.  
Note: Check for active backups on the Dashboard’s Devices tab. The screen displays  
backups in progress.  
Once the Connector software is installed, set up an automated scheduled backup (for after  
working hours) using the Dashboard. Running a manual backup during the initial connection  
process will impact overall system performance.

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. The operating system and all data are  
protected by the RAID structure. The server automates the management of the RAID.  
Your WD Sentinel server uses RAID 5, which offers fast performance by striping data across  
all drives, This RAID level provides the system with both redundancy and optimum capacity.  
2 TB Drives 3 TB Drives 4 TB Drives  
RAID Level 5 (4  
Drives)  
8 TB Capacity 12 TB  
Capacity  
16 TB  
Capacity  
If a drive in the array fails, the data and operating system are still intact, and the  
WD Sentinel server continues to provide service.  
Important: If you have one bad drive, the server operates normally. However, if a  
second drive fails, the server will no longer operate. You will need to  
recover the server and/or replace the failed drive(s). A best practice  
is to have a replacement drive readily available.  
The WD Sentinel server lets you know when a drive fails in the following ways:  
The LED below 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 “Monitoring System  
Health and Alerts” on page 33.)  
To recover from a failed drive, simply replace the drive (the one with the red LED over the  
drive) with an approved drive for the WD Sentinel server (see “Find compatible hard drives”  
on page 36)  
Once replaced, complete the steps outlined in “Recovering from a Failed Drive” on page 48  
to integrates the new drive into the RAID array. This process takes many hours to  
accomplish. Progress of this operation appears on the Dashboard. While the server is  
verifying the RAID array, your data continues to be available although 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.

MANAGING STORAGE ON THE WD SENTINEL SERVER  
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), RAID1 or RAID5, but at a higher abstraction level.  
A storage space behaves like a physical disk to the user, with thin provisioning of available  
disk space. 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, SAS). 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.

in different places on multiple hard drives, providing necessary redundancy, greater  
performance, and data integrity.

the unit. The USB 3.0 ports can connect to external USB 2.0 or USB 3.0 storage devices or  
to a UPS device for power outage conditions. For example, WD My Passport or WD My  
Passport Essentials may be used to connect to the WD Sentinel server. You can share this  
data on your USB drive with other users connected to the server by using the Dashboard,  
which treats the USB drive as a share. You can set user privileges just as you do with shared  
folders on the WD Sentinel server’s drives. The server manages UPS capability through a

Moving a Server Folder  
It is a best practice to move any folders you may have on your server boot drive (C:) to your  
shared data drives. Use the following steps to move a folder on your server to another  
location on your server. When you perform this task, ensure that the new location has a  
maximum amount of free space.  
Note: If possible, avoid moving a shared folder to your server’s system drive (such as C:\ )  
This may take away the necessary drive space required for your operating system  
and its updates.  
Note: Avoid moving share folders to an external hard drive. Once moved, you may not be  
able to access these files in a folder on an external drive because they can be easily  
disconnected. Instead creating the folder on an internal drive is recommended.  
A server folder cannot be moved to the following locations and will result in an error if any  
one of these locations is selected for a move:  
a hard drive that is not formatted with the NTFS or ReFS file system.  
the %windir% folder.  
a mapped network drive.  
a folder that contains a shared folder.  
a hard drive that is located under Device with Removable Storage.  
a sub-folder of a shared folder.  
Before you move a folder ensure that:  
You’ve backed up your device (See “Backing up your WD Sentinel Server” on  
page 70.).  
None of the files within the folder you’d like to move are currently in use.  
Use the following steps to move a server folder.  
1.

3.  
On the Dashboard, click Storage.  
On the Server Folders tab, select the folder that you want to move.  
In the Tasks pane, click Move the folder.

Backing up (Windows PC)  
The WD Sentinel server backup is based upon block level de-duplication, a process that  
backs up data without unnecessarily backing up the same data more than once. This  
powerful process uses less network traffic for execution, provides a full back-up at each  
backup time (although it behaves as if it is incremental), and by executing de-duplication  
across all client computers, the storage capacity requirements are significantly reduced.  
Backup becomes an automatic process for a computer once you install Connector software  
on it. With Connector software installed, all volumes and all NTFS data on that computer are  
backed up.  
Note: For information on backing up your Mac using Time Machine, See “Backing up with  
Time Machine (Mac)” on page 64.

Setting up the WD Sentinel Server  
Setting up Client Computers  
Using the WD Sentinel Server Efficiently  
Replacing Drives  
Sharing Files with External Users  
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 for both the Launchpad and their computer.  
If you decide to lock the drives, 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.  
Set up Remote Web Access using Ports 443 and Port 80. If your router or IP  
provider blocks these ports, you may need to consult with your IP provider for  
assistance.  
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.  
Setting up Client Computers  
Before loading the Connector software to add a computer to the  
WD Sentinel server for backup, be sure that the computer’s operating system is  
fully up-to-date.  
When adding client computers to the WD Sentinel server, it is best not to have any  
backups active.  
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.  
To avoid RAID issues, always use Sentinel with a UPS.  
Enable e-mail alerts. Receiving your alerts by email allows you to monitor certain  
server issues as they occur.

BEST PRACTICES  
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 unrecoverable failure will  
occur should another drive be removed. Only remove one drive at a time between  
rebuilds.  
Avoid pulling a drive out unless there is a failure.  
When a drive needs replacement, the WD Sentinel server is still functional but  
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.  
Sharing Files with External Users  
Create Employee-Specific Private Folders/Assign Permissions—Depending on the  
nature of your business and organizational structure, you may want to create a  
shared folder for each employee and give the respective employee Read/Write  
permissions for that folder.  
Create Shares for Vendors or Clients/Access Remotely—The built-in Remote Web  
Access feature enables collaboration on files and data not only among your  
employees but also with your clients and vendors.  
As a best practice, create a unique user account for each client and vendor you  
want to exchange data with and create a dedicated Shared Folder for each such  
external user. To prevent giving external users access to your sensitive data, make  
sure that the user accounts you create have the appropriate permissions for only  
the folders you have created for them.  
To start collaborating with your external users, just provide them with the domain  
address of your WD Sentinel server and their user name and password.  
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).  
Note:  
Performance is affected during a RAID rebuild and verification.  
To avoid possible corruption, do not unplug the power from the unit while it is  
running.
