Buffalo TeraStation™ WSS 5000 2 Bay with Windows® Storage Server 2012


TeraStation™ WS5200D brings you the power of Windows® Server OS and Intel® Atom™ Dual-Core Processor in a 2-bay form factor. The TeraStation™ WS5200D is powered by the Microsoft Windows® Storage Server 2012 Workgroup Edition, providing seamless integration with all Windows® computers and servers.

Equipped with Intel® Atom™ Dual-Core Processor & DDR3 memory

The TeraStation™ WSS 5000 Series is equipped with Intel® Atom™ Dual-Core Processor, 4GB DDR3
memory, and USB 3.0, maximizing the data transfer speed to support large data transfers and multiple data
transfers which occurs constantly in daily business operations.

*Test conducted by Buffalo on December 2012.
[PC] Motherboard: Intel DH77KC (PU-0015), Chipset: Intel H77, BIOS: KCH7710H.86A.0095.2012.0608.1754,
CPU: Intel Corei3 2100, Memory: DDR3-1600 2GB, System: 64bit OS, Gigabit Ethernet: Intel 82579V Gigabit Network Connection,
HDD: Seagate ST31000DM003 x2 RAID, OS: Windows7 x86 Professinal SP1 [NAS] WS5600D, WS-6VL/R5
Connected WS5600D and WS-6VL/R5 to PC by LAN and mounted as network drive, then ran five tests
using NASPT Ver.1.71. Above value has been taken from the average of three test results, excluding maximum and minimum value.
*Measured values were obtained in a specific test environment; this does not necessarily gurarantee similar results can be
achieved in all operating environments.

Seamlessly share large files from multiple location within the network

With TeraStation™ WSS 5000 Series, you can share large files within the network with cross-platform support for versatility and access restrictions for security.

Expand your existing server's storage capacity with iSCSI

The TeraStation™ WSS 5000 Series can be used as an iSCSI storage array, allowing you to expand the storage space of your existing server. Since this can be done through the LAN network, installation location can be flexible.

Increase storage capacity for virtual server environment with iSCSI

The TeraStation™ WSS 5000 Series can be used as additional storage for virtual server environment.
By mirroring two TeraStation™ WSS 5000 Series, system with greater redundancy can be created.

HDD replaceable with optional hard drive cartridge

The TeraStation™ WSS 5000 Series uses cartridge type tray for easier HDD replacement. HDD can be
quickly replaced by lifting the lever and sliding the cartridge out from the slot. No need to remove screws.
OP-HDS, an optional hard drive cartridge for TeraStation™ 5000 Series can be used for replacement.

Efficient account administration with Active Directory support

The TeraStation™ WSS 5000 Series uses the account information registered in the Active Directory server
to control access to files and folders stored on the unit. This means that it requires no separate account
management. In addition, the server can accommodate an unlimited number of registered users and groups,
so it can be used even in large-scale environments. Active Directory centralizes management of account
information, which vastly reduces the work of setup and administration, even with systems using multiple units.

Group administration function provides flexibility and rigorous security

Read-only and read-write attributes can be set for the individual folders and files residing on the unit. You can
also restrict access to shared folders for groups and users individually for secure, efficient data management.

Quota function allows setting of users' available capacity

File server resource managers can set and manage the amount of storage capacity, in folder and volumes.
Managers can also set NTFS quotas*, providing users and groups the appropriate amount of disk space while
preventing any one user or group from making excessive use of the hard drive.

*Volume must be formatted for NTFS

Two different network segments can be connected using two LAN ports

The TeraStation™WSS 5000 Series is equipped with two LAN ports, enabling access from each segment to
be managed separately. Unrelated divisions are prevented from connecting to each other's networks, while
being allowed to access the data stored on their own folders in the TeraStation™ WSS 5000 Series.

No need to purchase individual Client Access License (CAL)

Regular Windows® Server OS requires Client Access License (CAL) in each clients in order to access the
server OS. With the Windows® Storage Server 2012, which is installed in this TeraStation™
5000 Series,there is no need to purchace individual CAL to access the server OS. This helps reduce the
initial cost of installing a server in your office.

DFS replication allows you to save data to a remote location via the network

The TeraStation™ WSS 5000 Series supports "DFS Replication", which allows you to back up files to a
TeraStation™ WSS 5000 Series in a different location via the network. Backing up data to a remote location
via the Internet protects your data, even when there is a breakdown locally. Even if a natural disaster or other
such major problem occurs at the head office, the backup data in the remote locations allow to recover data.

*Difficulties in backing up may occur in some network environments. We recommend that the system be evaluated and
verified in advance.
*Use of this function requires Active Directory on Windows Server 2003 R2 or later. In addition, the two TeraStation™ WSS 5000
Series units must be located in the same forest.

Multiple backup options available

- Replication
Replicates data between two TeraStations. In the event of a TeraStation failure, simply unplug the Ethernet
cable from the malfunctioning TeraStation and plug into the backup TeraStation for service restoration.

*Supported after firmware update

- Scheduled backup
Scheduled backup can be set at a specific date and/or time.

*Supported after firmware update

- Many-to-one TeraStation Backup
Backup all shared folders in multiple TeraStations on a single TeraStation

*Supported after firmware update

Added data protection with RAID 1 and 0 support

There are two internal HDDs equipped in the unit and features "RAID", a technology that can recognize and
show multiple hard drives like a single drive and which allows the storage to be configured in accordance with
the user's needs. Using RAID 1 mode, for example, if one internal drive fails, you can recover the content,
There are two internal HDDs equipped in the unit and features "RAID", a technology that can recognize and
Normal mode, in which the two drives are used as independent drives.

Joining Active Directory makes administration more efficient

Copies of the shared folder can be created automatically according to administrator-specified schedules.
If a user accidentally deletes afile,the user himself can use Explorer or a major Microsoft Office application* to directly restore the deleted file to when last saved.

*User of Shared Folder Shadow Copy requlres th cllent computer to be running Windows XP SP2 or later.

Hardware supporting 24/7 operation

Extremely reliable hardware

The design of the unit and ventilation fan help ensure air flow,which is critical in holding down temperatures inside the case.The fan used id very quiet.It also monitors temperatures within the case and automatically regulates the fan speed for quiet yet effective cooling.

Utilizes specially designed,highly reliable power supply unit

The components are rigorously designed to handle high-temperature environments and extended operation. The highly reliable power supply withstands even continuous 24-hour-a-day use.BUFFALO recommend confidently to even business users with systems running for long hours.

Front panel dust filter

The filter prevents dust from getting inside the unit,which reduces the load on the fan and contributes to more stable operation.

Hot-swappable hard drive

The inernal drives are hot-swappable,so they can be replaced in the event of a hard
drive failure, with no need to switch off the power. It is designed to minimize effects
on the system when disks are replaced. are replaced.The RAID array absent the failed hard drive allows the system to be used as usual,even while the drive is being replace,so there is no extra obstacle to normal business operations.

In the unlikely event of an internal drive filure,the failed drive can easily be replace by the user.Replacement is a snap,no screwdriver or other tools are required.

*For safety,please wear gloves or similar protection when replacing disks.
*BUFFALO assumes no liability whatsoever for loss of data on drlves damaged during transport, whether for warranty repair or free repair.
*Replacement drives other than conforming modeis are not supported.
