The TS-259 Pro is the powerful 2-bay network attached storage (NAS ) server, which is designed to provide an affordable and easy-to-management solution with iSCSI service for virtualized and clustered environment. The TS-259 Pro also offers versatile business applications to maximize the efficiency of the data center in the business environment.

Incorporating the next-generation Intel® Atom D510 1.66GHz Dual-Core processor and 1GB DDRII RAM, the Turbo NAS delivers exceptional performance and maintains high reliability for multiple concurrent applications and intensive data transfer with guaranteed low power consumption.

The Most Affordable and Flexible Virtualization Solution
The TS-259 Pro is certified as compatible with VMware® vSphere4 (ESX 4.0 and above) virtualization platform. The NAS can be utilized as the networked shared storage of VMware virtualization environments and Windows cluster servers. Comparing with traditional SAN (Storage Area Network), the Turbo NAS is a competitive alternative with much lower setup and maintenance costs in an IP SAN.

The Feature-rich and Integrated Applications for Business
The NAS supports file sharing across Windows, Mac, Linux, and UNIX platforms. Versatile business applications such as file server, FTP server, printer server, web server, and Windows AD support are provided. The dominant features, such as WebDAV, Share Folder Aggregation (also known as DFS), IPv6 and IPv4 dual-stack, Wake on LAN, schedule power on/ off, HDD S.M.A.R.T, comprehensive log systems, and policy-based unauthorized IP blocking are all included features of a QNAP NAS server.

New iSCSI for Virtualization Deployments
The Turbo NAS provides flexible and secure storage server deployment with the following enhanced iSCSI features:

• NAS + iSCSI storage solution
  The Turbo NAS can serve as a NAS for file sharing and iSCSI storage concurrently.
• Flexible multiple LUNs management
  The NAS supports multiple LUNs (Logical Unit Numbers) and iSCSI targets. The LUNs can be flexibly mapped to, unmapped from, and switched among different iSCSI targets.
• Secure IP SAN environment deployment
  Designed with CHAP authentication and LUN masking, the advanced ACL (Access Control List) offers you the capability to block unauthorized access from the initiators.
• Designed for virtualized and clustered environments
  Comparing with the high cost of Fibre Channel SAN, the Turbo NAS is an affordable system that can be deployed as a storage center for virtualized and clustered server environments, such as VMware and Microsoft Windows Failover Cluster.

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 LUN on the network.

Superior Performance and Eco-friendly Design
The NAS delivers superior performance and high reliability for critical business applications. It is optimized to achieve low noise and low power consumption for environment protection.

SAMBA/ FTP Access

• FTP/SAMBA Testing Environment: Intel Core2 Quad CPU Q8300 2.50GHz/ 4GB DDRII RAM, WD640AAKS 640GB, Windows 7 Enterprise 32 Bits,Intel PRO 1000 PT Dual Port Server Adapter 82571
• FTP/SAMBA Testing Method: Connect the TS-259 Pro and PC to switch, upload/download 5GB File without Jumbo Frame, FTP Tool: File Zilla

Abundant Business Features
The Turbo NAS provides diversified server applications in the business environment.

1		FTP Server: You can establish your own FTP server by the Turbo NAS and share the files conveniently with your friends or customers.
2		Encrypted Remote Replication: The data on the Turbo NAS can be backed up to or from other Turbo NAS or Rsync servers over the network.
3		File Server: The Turbo NAS allows file sharing across Windows, Mac, Linux, and UNIX platforms. It also supports WebDAV for you to access the share folders via HTTP/HTTPS protocol remotely.
4		Printer Server: The Turbo NAS supports USB printer sharing over the network (max. 3 USB printers).
5		Backup Server: The Turbo NAS offers you the most complete backup solution with Apple Time Machine support, remote replication to an Rsync server, Windows client backup software NetBak Replicator, and third party backup software support, and so on.
6		Web Server: You can easily create a website to publish information over the Internet using the built-in web server by the Turbo NAS.
7		Surveillance Station: The Turbo NAS enables you to configure and connect multiple IP cameras simultaneously for remote monitoring, video recording and playback.
		IPv6: The Turbo NAS supports IPv6 (Internet Protocol Version 6) which makes your NAS a dual-stack IP host running IPv4 and IPv6 at the same time.

Advanced RAID Management with Hot-swap Design
The NAS offers RAID 0, 1, single, and JBOD disk configurations. It also supports hot-swap design that a failed member drive of a RAID configuration (RAID 1 or above only) can be replaced by hot swapping without turning off the server.

Online RAID Capacity Expansion
The storage capacity of a RAID configuration can be expanded by replacing the larger hard drives. All the data will be kept and seamlessly moved to the newly installed hard drives without turning off the server.

Online RAID Level Migration
You can upgrade the disk configuration to higher RAID level with the data retained without turning off the server.

The Most Complete Backup Solution
The NAS offers complete backup solution for data protection, including cloud-based storage backup (Amazon S3), Apple Time Machine support, encrypted remote replication, third party software backup, one-touch-copy backup and QNAP exclusive Windows-based utility NetBak Replicator. The users can choose different backup modes for redundant data backup.

Practical System and Authority Control Management Tools

	Instant SMS and Email Alert You can configure the SMTP server and SMSC server settings on the NAS in order to receive instant system warning or error messages by email and/or SMS.
	SNMP (Simple Network Management Protocol) You can collect the information, warning or error of the NAS and send to maximum 3 SNMP servers for centralized management and real-time monitoring.
	Comprehensive Event Log System Detailed logs of file-level data access to the NAS via SAMBA, iSCSI, FTP, AFP, HTTP, HTTPS, Telnet, and SSH, and networking services accessed by online users are all recorded.
	Wake on LAN Enable this option to power on the Turbo NAS remotely by Wake on LAN. Wake on LAN helps you manage your NAS conveniently.
	S.M.A.R.T. & Advanced HDD Health Scanning (HHS) S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) helps you to monitor the HDD status. Moreover, the Turbo NAS is embedded with HHS (HDD Health Scan) which supports disk checking and bad blocks scanning.

Windows Active Directory (AD)
The Windows AD feature enables you to retrieve the user accounts from the Windows AD server to the NAS to reduce the time and effort for account setup. Users can use the same set of login name and password to access the NAS.

Share Folder Aggregation
You can easily access the share folders of other servers on Microsoft Networking through the “portal folder” on the Turbo NAS. This saves your time and effort to login different servers one by one.

AES 256-bit Volume-based Data Encryption
The disk volume with AES 256-bit encryption can only be accessed by an authorized encryption password or key. This prevents the NAS data from unauthorized access and data breach even if the hard drives are stolen.
*Data encryption functions may not available in accordance to the legislative restrictions of some countries.

DOM Architecture and Fail-safe Dual OS
Two operating systems are built on the DOM of the Turbo NAS for system booting alternatively upon every system startup. When one fails, the other one will be used to boot up the NAS, and the failed OS is recoverable from the other healthy OS.

Software Expansion via QPKG
The QPKG feature enables the users to maximize the usage of Turbo NAS by installing additional software packages developed by the users and community worldwide.
