QNAP
TS-239 Pro is the new generation 2-bay model of the worldwide
award-winning Turbo NAS Series designed to deliver high performance and
reliable server features such as advanced RAID protection, built-in
iSCSI target service, and AES 256-bit volume-based encryption for small
business.

Powered by Intel 1.6 GHz CPU and 1GB
DDRII memory, the TS-239 Pro is the 2-bay NAS with the best hardware
specifications in the current market. The NAS comes with two Giga LAN
ports which can be configured for network failover, load-balancing, and
multi-IP setting. Advanced disk configurations such as RAID 0/ 1, JBOD,
Online RAID Capacity Expansion and Online RAID Level Migration are
supported.

The TS-239 Pro can serve as a NAS and an
iSCSI target server. You can make use of the iSCSI target service to
set up the NAS as a device for storage capacity expansion or a backup
server of the existing servers on the local network. The “Virtual Space
Allocation” (Thin Provisioning) feature is provided that you can
flexibly allocate the capacity of iSCSI LUN (Logical Unit Number) at
the beginning regardless of the physical volume capacity of the NAS.

To
meet the demand for high security data protection of the business
users, the TS-239 Pro supports AES 256-bit volume-based encryption. The
encrypted disk volumes of the NAS must be unlocked by the encryption
password to be accessed, which eliminates the fear of confidential data
leakage if the hard drives or the NAS were stolen. Moreover, the TS-239
Pro supports file sharing across Linux, UNIX, Mac, and Windows. It
provides numerous applications, e.g. file server, FTP server, printer
server, web server (with phpMyAdmin, MySQL, SQLite, Joomla!). It is an
ideal storage solution for your office network.

Brand new user Interface available

Feature-rich Applications for Business

The TS-239 Pro supports file sharing across Linux, UNIX, Mac, and
Windows platforms. Different applications are supported, e.g. file server, FTP server, printer server, web server, and encrypted remote replication.
Also, windows AD (Active Directory) is supported to help create an
easy-to-access environment and lower the maintenance cost. SSH login
and web page SSL login enable users to transfer, store, and share data
securely.

The Most Affordable and Flexible iSCSI Solution

The TS-239 Pro can serve as a NAS and an iSCSI target server. The
built-in iSCSI target feature provides an affordable IP-SAN (Storage
Area Network) alternative for SMB. You can set up the NAS to expand the
storage capacity for existing application servers, such as database
server and mail server in an economic way. Moreover, the "Virtual Space
Allocation" (Thin Provisioning) feature is provided which allows you to
flexibly allocate the capacity of iSCSI LUN (Logical Unit Number) at
the beginning regardless of the physical volume capacity.

Secure Data Protection by AES 256-bit Volume-based Encryption

The TS-239 Pro's dominant "volume-based encryption" feature secures the
server data by AES 256-bit encryption. Even if the hard drives were
stolen, there is no need to fear that the confidential data would be
leaked since the data can only be accessed by an authorized password.

*Note: Data encryption functions may not be available in accordance to legislative restrictions of some countries.

Benefits of Dual Gigabit LAN Deployment

Failover Supported for Network Reliability

The dual LAN ports can be configured as failover which allows the NAS
server to sustain the failure of one network port to provide continuous
services.

Better Performance with Load Balancing

The two LAN ports of the NAS can be configured as load balancing mode
for bandwidth aggregation to boost the file transfer speed (works with
managed Ethernet switch with 802.3ad configured).

Multi-IP Setting for Serving Two Different Subnets

The NAS can be deployed with two IP settings for sharing among different workgroups in two different subnets.

High Reliability, Disaster-proof NAS for Business

DOM Architecture with Embedded Fail-safe Dual OS

All the OS and applications are embedded on the DOM. The NAS allows
system booting without accessing the physical disk sectors and that
avoids unsuccessful system startup caused by bad block sectors or file
errors on the hard drives. Two operating systems are built on the DOM
for system booting alternatively upon every system startup. When one
fails, the other one will be used to boot up instead, and the failed OS
is recoverable from the other healthy OS.

Advanced RAID Management with Hot-swap Design

The Turbo NAS supports RAID 1 Mirroring for non-stop service and easy
maintenance. When data crash occurs, the administrator can be alerted
by e-mail alarm and LED indication. The hard disk drive can be replaced
by hot swapping without turning off the server. The intelligent data
rebuilding capability allows users to replace a failed drive by
hot-swap. This enables automatic data rebuilding to the new drive
without suffering from any system downtime.

Online RAID Capacity Expansion

The storage capacity of a RAID configuration can be expanded by
replacing the hard drives with larger ones. All the data will be kept
and seamlessly moved to the newly installed hard drives. There is no
need to turn off the server during the process.

Online RAID Level Migration

You can upgrade the disk configuration to higher RAID level with the
data retained. There is no need to turn off the server during the
process.

Virtual Disk Drive (VDD) adds flexibility to storage expansion along with ease of management

The unique "Virtual Disk Drive" adds flexibility to expand the capacity
of NAS. By using the built-in iSCSI initiator, the NAS can connect to
other iSCSI targets on the network and turn them into virtual disks,
which become multiple single volumes on the NAS. Up to 8 virtual disks
can be stacked. The NAS serves as the storage stack chaining master.
The user only needs to connect to this single entry (QNAP NAS) and is
able to reach and use all the iSCSI target storages on the network.

Built-in iSCSI Target Service

The TS-239 Pro can act as a NAS and iSCSI target server at the same
time. It provides a cost-efficient iSCSI solution to set up an IP-SAN.
You can make use of the built-in iSCSI target service to add up to 8
iSCSI devices. Different iSCSI Target LUNs (Logical Unit Number) can be
defined as storage expansion or backup destination of the existing
application servers, such as database servers and mail servers.

Furthermore,
the "Virtual Space Allocation" (Thin Provisioning) feature is provided
which allows you to flexibly allocate the capacity of iSCSI LUN
(Logical Unit Number). When the physical storage capacity of the volume
is going to be full, you can easily expand the storage capacity by
"Online RAID Capacity Expansion", or adjust/ remove the current unused
volume space according to the demands.
