SS-839 Pro Turbo NAS

Overview

T

he SS-839 Pro Turbo NAS is the 8-bay, 2.5” SA TA HDD network-attached
storage server for business users who need a power-saving, high
performance, and reliable network storage solution with professional
features such as advanced RAID protection, built-in iSCSI target service,
and AES 256-bit volume-based encryption.

Energy-saving and Quiet Design

The SS-839 Pro is the smallest 8-bay NAS in the market and can be easily
deployed anywhere in the office. It is also an energy-saving storage solution with
excellent cooling and low noise design. The power consumption of the SS-839 Pro
is only 34W in operation (in RAID 5 configuration with eight 500GB hard drives
installed), which helps save your electricity expense to a large extent.

Superior Performance and Advanced RAID Redundancy

Powered by Intel Atom 1.6 GHz CPU and 2GB DDRII memory, the SS-839 Pro
supports RAID 0/ 1/ 5/ 6/ 5 + hot spare, single, and JBOD, Online RAID
Capacity Expansion, and Online RAID Level Migration.

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

To meet the demand for high security data protection of the business users,
the SS-839 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.

iSCSI Solution with Virtual Space Allocation

The SS-839 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. Also, 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.

Versatile Applications for Business

The SS-839 Pro supports file sharing across Linux, UNIX, Mac, and
Windows platforms. Versatile business applications are supported, e.g. file
server, FTP server with encryption, printer server, web server, and remote
replication. Also, Windows AD (Active Directory) is supported to help create
an easy-to-access environment and lower the maintenance cost.

Easy Setup and Low-cost Maintenance

The handy LCD display on the NAS provides a speedy and easy approach
for you to initialize the NAS and set up the RAID configuration without using
any computer. The system information and settings are also displayed for
easy management. The schedule power on/off feature is available on the
NAS for you to flexibly manage the NAS server's up time according to the
working hours. Also, the smart Wake on LAN is supported for convenient
remote wakeup of the NAS in the local network.

The Best Storage Solution for Power Conservation

The SS-839 Pro delivers distinguished energy-saving performance and reduces the
electricity consumption to a large extent by supporting the 2.5” SATA hard drives. The
power consumption of the NAS in operation with eight
hard drives installed is as low as 34W. The power
consumption of SS-839 Pro is almost 60% less than
general 3.5” SATA HDD 8-bay NAS. Also, the NAS adopts
predominant heat dissipation and ultra silence design,
making it a cool and quiet solution in the working
environment with the use of the low vibration and highly
reliable 2.5” hard drives.

Advanced RAID Management

Advanced RAID Management with How-swap Design

The NAS offers advanced RAID 0, 1, 5, 6, 5 + hot spare, single, and JBOD disk
configurations. It also supports hot-swap design that a failed drive can be
replaced by hot swapping without turning off the server.

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.

Flexible Built-in iSCSI Solution

Built-in iSCSI Target Service

For small business, a high-performance and flexible storage expansion solution
for the existing application servers is required. However, DAS (Direct Attached
Storage) is not an efficient solution and a Fiber Channel SAN is too expensive
and complicated to implement.

The SS-839 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.

Virtual Space Allocation (Thin Provisioning)

The “Virtual Space Allocation” (Thin Provisioning) feature is provided which allows
you to flexibly allocate the capacity of iSCSI LUN at the beginning regardless of
the physical volume capacity. When the physical storage capacity of the volume is
going to be full, you can easily expand the storage capacity of the NAS by “Online
RAID Capacity Expansion”, or adjust/ remove the current unused volume space
according to the demands.

AES 256-bit Volume-based Data Encryption

The SS-839 Pro’s dominant “volume-based encryption” feature enables you to
build encrypted disk volumes on the NAS for the first time installation. The disk
volume is securely protected by AES 256-bit encryption. An encryption key is
required to unlock the encrypted volume to access the server data. This prevents
data leakage if the server or the hard drives were stolen.

Software Expansion via QPKG

The QPKG software package platform enables the users to maximize the usage
of Turbo NAS by installing additional software packages developed by the users
and community worldwide.

USB One Touch Auto Copy

The one touch copy button can be configured to trigger data backup from the
external USB device to the NAS or the other way round (applies to the USB
device connected to the front USB port of the NAS only). Press the button for 3
seconds and the backup will start instantly.

DOM Architecture and Fail-Safe Dual OS Protection

All the OS and applications are embedded on the DOM (Disk on Module) of the
SS-839 Pro to allow system booting without accessing the physical disk sectors, which
prevents 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.

Convenient System Tools
