The SS-439 Pro Turbo NAS from Qnap is a power-conscious tower NAS server. Four SATA HDD bays accommodate 2.5" hard drives, allowing you to store your media and other files in a centralized location and access it from any computer or other device on your network. The fast 1.6GHz Intel Atom CPU and 1GB of RAM ensure that data retrieval is fast and efficient. The server supports a variety of RAID configurations, allowing you to customize your system based on whether you'd prefer more storage or security.

The SS-439 Pro can function as a web server (phpMyAdmin is built-in) or a MySQL server. You can also connect it to a printer for network printer sharing. A one-touch copy feature makes backing up your data simple and straightforward. A wide variety of management tools let you get the most out of your NAS, including scheduled events, event tracking, UPS support and SMS support.

Feature-rich Applications for Business
The SS-439 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.
Affordable and Flexible iSCSI Solution
The SS-439 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 256-bit Volume-based Encryption
The SS-439 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. 1

Benefits of Dual Gigabit LAN Deployment

Failover
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.
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
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 + 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)
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.
Flexible Built-in iSCSI Target Service
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.

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.
S.M.A.R.T. & Advanced HDD Health Scanning (HHS)
The NAS supports Hard Disk Drive S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) for monitoring the hard drive status. Moreover, the NAS is embedded with HHS Technology which supports disk checking and bad blocks scanning.

Power Management

Hard Disk Standby
You can configure the hard disks to enter standby mode if there is no disk access within the specified period.
Schedule Power On/Off
The flexible schedule power on/off feature is now provided on the NAS for IT administrators to manage the NAS server's up time according to the working hours. You can set the time for automatic system power on, power off, or restart on any days of the week.
UPS Support
The NAS supports the majority of USB UPS devices (usbhid-ups supported) which enables the users to store the data in time and avoid critical data loss when power outage occurs during data transfer. It also supports advanced stand-by mode setting that users can set the time for the server to enter standby mode when an abnormal AC power supply is detected. When the power resumes, the server resumes to the operation status before the power outage.
Auto Power on after Power Loss
You can configure the NAS to turn on/ off when the AC power resumes after a power loss.

Cross-platform Data Sharing and Storage Center

Sharing Files across Windows, Mac, Linux, and UNIX
The NAS is designed for users to share the files across Windows, Mac, Linux, and UNIX environment.
Windows AD
