Modern businesses face the challenges of dramatic growth of digital data as well as raising productivity and efficiency. To well deploy the business IT environment with a reliable, affordable, scalable, and easy-to-maintain storage center to securely store, share and back up the digital assets has become the top task for the server managers nowadays in small and mid-sized companies. The Turbo NAS is the brand-new rackmount chassis network attached storage (NAS) server to satisfy these requirements.

The Turbo NAS is equipped with the next-generation Intel® Atom™ Dual-core 1.8GHz Processor delivering exceptionally high performance, yet with low power consumption for energy-saving commitment. The Turbo NAS provides versatile business applications to maximize server consolidation in the business environment. The Turbo NAS is integrated as a powerful all-in-one application server, which requires no extra time and efforts for software installation. The server managers can adopt the NAS in many of the system integration projects or office applications quickly. The Turbo NAS is also an affordable solution capable of business-class server applications, secure data backup and sharing, and iSCSI service for virtualized and clustered environment.

The Most Affordable and Flexible Virtualization Solution
The TS-859U-RP+ 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/ IP SAN for Virtualization Deployments
The Turbo NAS provides flexible and secure storage server deployment with the following enhanced iSCSI features:

• NAS + iSCSI/ IP SAN 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.

Redundant Power Supply
The TS-859U-RP+ is equipped with two power supply units, each of which is capable of supplying the power for the entire NAS independently. If one of the units fails, the other one will take over to supply the power to ensure continuous operation of the NAS. You can replace the failed power supply unit without turning off the server.

Hard Disk Standby
The hard disks can be configured to enter standby mode if there is no disk access within the specified period.

Scheduled Power on/ off
The flexible scheduled power on/off feature is provided on the NAS for you to manage the NAS server's up time according to the working hours.

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 you 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.
