SS-439 Pro

Caratteristiche

QNAP SS-439 Pro is the new generation 2.5" SATA 4-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.

The SS-439 Pro houses four reliable and low power 2.5" SATA hard drives with the total storage capacity of up to 2TB. It is particularly designed for business users who are looking for a network storage solution of high data security for data backup and numerous powerful server applications. The SS-439 Pro is an energy-saving server with low heat output and low noise level.

Powered by Intel Atom 1.6 GHz CPU and 1GB DDRII memory, the SS-439 Pro supports RAID 0/ 1/ 5/ 6/ 10/ 5 + hot spare, single, JBOD, Online RAID Capacity Expansion, and Online RAID Level Migration. To meet the demand for high security data protection of the business users, the SS-439 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. 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. 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.

Moreover, the SS-439 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 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.

The Most 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 AES 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.

*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 NAS offers advanced RAID 0, 1, 5, 6, 10, 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-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.
