SS-439 Pro Turbo NAS
Benefits of Dual LAN Deployment
Network Failover
Failover allows the NAS to
sustain the failure of one
network port to provide
continuous services.
Load-balancing
Bandwidth aggregation is
supported to boost the file
transfer speed (works with
managed Ethernet switch
with 802.3ad configured).
Multi-IP Setting
The NAS can be deployed
with two different IP settings
for sharing among different
workgroups in two different
subnets.
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. 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 configura-
tion 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.
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-439 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 (Logical Unit Number) 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.
Web Server
With the built-in phpMyAdmin, Joomla!, editable php.ini, MySQL
and SQLite, you can easily set up your web server and other
online applications such as online shops, forums, and blogs.
MySQL Server
The Turbo NAS is the most affordable choice as a standalone
database server. It can be applied as a database server of
another web server or as an additional backup database server.
The SS-439 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.

AES 256-bit Volume-based Data Encryption
The SS-439 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 four
hard drives installed is as low as 18W, which is almost
the same as an energy-saving light bulb. 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.

DOM Architecture and Fail-safe Dual OS Protection
All the OS and applications are embedded on the DOM of the SS-439 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.
Printer Server
You can connect a USB printer to the NAS to enable network
printer sharing. The NAS supports up to 3 USB printers.

HDD S.M.A.R.T.
The NAS supports Hard Disk Drive S.M.A.R.T. (Self-monitoring
Analysis and Reporting Technology) for you to monitor the hard
drive condition and prevent potential data loss.
Wake on LAN
Enable this option to power on the NAS remotely by Wake on
LAN. Wake on LAN helps you manage your NAS conveniently.
