TS-239 Pro Turbo NAS

Overview

QNAP TS-239 Pro is the new generation 2-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. Powered by Intel 1.6 GHz CPU and 1GB DDRII memory, the TS-239 Pro is the 2-bay NAS with the best hardware specifications in the current market. The NAS comes with two Giga LAN ports which can be configured for network failover, load-balancing, and multi-IP setting. Advanced disk configurations such as RAID 0/ 1, JBOD, Online RAID Capacity Expansion and Online RAID Level Migration are supported.

The TS-239 Pro can serve as a NAS and an iSCSI target server. You can make use of the iSCSI target service to set up the NAS as a device for storage capacity expansion or a backup server of the existing servers on the

Online RAID Capacity Expansion and Online RAID Level Migration

The TS-239 Pro supports Online RAID Capacity Expansion for expanding the storage capacity of the RAID 1 configuration and Online RAID Level Migration for upgrading the disk configuration to higher RAID level. It also supports RAID 0, 1, single, and JBOD disk configurations. The hot-swap design allows you to replace a failed member drive of the RAID 1 configuration without turning off the server.

AES 256-bit Volume-based Data Encryption

The TS-239 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.

local network. The “Virtual Space Allocation” (Thin Provisioning) feature is provided that you can flexibly allocate the capacity of iSCSI LUN (Logical Unit Number) at the beginning regardless of the physical volume capacity of the NAS.

To meet the demand for high security data protection of the business users, the TS-239 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. Moreover, the TS-239 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.

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 TS-239 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.

Benefits of Dual LAN Deployment

Secondary Network Connection

1. Data flow from clients

2. Data traffic evenly distributed to balance network loading

Supports access of multiple IP from different LAN areas

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.

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”.

DOM Architecture and Fail-Safe Dual OS Protection

All the OS and applications are embedded on the DOM of the TS-239 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.
