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.

Shutting Down and Rebooting the Server

The WD Sentinel server is intended to be on at all times, providing shared data and backup services. 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), follow the procedures below to shut down or reboot the server

It is very important that the WD Sentinel server be shut down or restarted in a clean and graceful manner through the Settings section in the Dashboard.

WARNING! To avoid a potentially unclean shutdown that could corrupt the

RAID configuration, shut down the server through the Dashboard.

To shut down or restart using the Dashboard (Preferred method):

1. Click Settings in the icon bar.

Managing Storage on the WD Sentinel Server

WD Sentinel Server RAID Storage Storage Spaces Setting Up Your Drives Using USB Storage Moving a Server Folder

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.

Setting Up Your Drives

Use the following steps to set up your WD Sentinel device drives.

1. On the Dashboard Home page, click Setup>Set up your drives.

2. Select Click to start setting up your drives. The Set Up Your Drives wizard displays.

Using USB Storage

The WD Sentinel server has two USB 2.0 port and four USB 3.0 ports on the back panel of 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 USB port for communication and to ensure an orderly shut down.

4. Click Ye s , then click Close.

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. On the Dashboard, click Storage.

2. On the Server Folders tab, select the folder that you want to move.

3. 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.

Best Practices

BEST PRACTICES

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.

WD SENTINEL DS5100/DS6100 ADMINISTRATOR AND MAINTENANCE GUIDE

Page 78

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.

BEST PRACTICES

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.
