 QNAP
SS-839 Pro Turbo NAS is the 8-bay, 2.5" SATA 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.
Brand new user Interface available
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 NAS 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.
*Note: Data encryption functions may not be available in accordance
to legislative restrictions of some countries.
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
encrypted 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
IT administrators 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 IT administrators 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" 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.
The Most Affordable and Flexible iSCSI Solution
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 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 SS-839 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.
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 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.
Besides, the best-in-class RAID on the NAS brings users a higher level
of data security by allowing one more hard drive failure than other NAS
of the same level.
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 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.
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.
