QNAP Turbo NAS Features

The TS-219P+ is a 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-219P+ also offers versatile business applications to maximize the efficiency of the data center in a small-scale business environment.

The Most Affordable and Flexible Virtualization Solution

The TS-219P+ 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.

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.

Advanced RAID Management with Hot-swap Design
The NAS offers advanced RAID 0, 1, 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 TS-259 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.

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.

QNAP Backup Software - NetBak Replicator
The backup software, NetBak Replicator, is provided for the NAS users to perform real-time synchronization or schedule backup from multiple PCs to the NAS.

3rd Party Backup Software Ready
The NAS works well with other backup software, e.g. Acronis True Image, CA BrightStor ARCserve Backup, EMC Retrospect, Symantec Backup Exec, and LaCie Silverkeeper.

Encrypted Remote Replication
The data on the NAS can be backed up to or from another Turbo NAS over the network securely.

One Touch USB Auto Copy
The one touch button can be configured to trigger instant data backup from the external USB device to the NAS or the other way round (applies to the USB device connected to the front USB port of the NAS only).

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.

Support Windows Active Directory
The Windows AD feature enables server manager to import user accounts from AD domain to NAS to reduce the time and effort for account setup, and users can use the same set of login name and password.

Web File Manager The NAS provides Web File Manager for you to easily download, upload, and manage the files on the server by web browser.

Ease of User and Share Folder Management
The NAS supports batch creation of users and share folders to save the time and effort of the server manager in account and folder creation. For the security of Windows network environment, server managers can hide or show network share folders.

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.

Secure data storage, access, and sharing

  • Comprehensive event logs: Detailed logs of file-level data access to the NAS via samba, FTP, AFP, HTTP, HTTPS, Telnet, and SSH, and networking services accessed by online users are all recorded.
  • SSL security (HTTPS): The NAS can be accessed and configured by web browser securely.
  • Remote login to the NAS by SSH (secure shell) or Telnet connection is supported.
  • Secure FTP: The data can be transmitted with SSL/TLS (explicit) encryption. Passive FTP port range setup is also supported.
  • Write-only access right on FTP server: The third party partners are allowed to upload data to the NAS but not able to read or edit the data on FTP server.

Policy-based Automatic IP Blocking
To prevent the NAS from malicious attacks, the server manager can create an IP filter policy to allow, deny, or auto-block the IP address or network domain which attempts to connect to the NAS via SSH/ Telnet/ HTTP(S)/ FTP/ samba/ AFP.

The most comprehensive support for numerous brands of IP cameras
The Surveillance Station of QNAP NAS supports all the leading network camera brands such as AXIS, D-Link, IPUX, LevelOne, Linksys, Panasonic and Vivotek etc. By using particular models, users can use two-way video and audio monitoring and recording, and smart PTZ control to control the monitoring direction via the web interface. Each of the supported cameras has been put through stringent tests with the NAS series in QNAP's laboratory to guarantee 100% compatibility and reliability with all these camera brands.

# Why no consumer drives?Dirk 2011-07-23 23:23
Hello,

to the "Cons" in the conlusion:
Why aren't consumer hard disks often the right choice for drive arrays, also a simple RAID-1 ?

I've heard about it before, but didn't find a real explanation. If you activate HDD sleep after xx idle minutes, the maximum hours of operation should be limited. What else?

QNAP has a detailed compatability list on their site, but you have to read between the lines to find out WHY consumer drives don't always cut it in RAID applications. Two things are primarily responsible: a software setting in the drive itself and the mechanical design of the platter bearings.

The consumer drives have an error recovery scheme that can interfere with the RAID controller, calle "Time-Limited Error Recovery" (TLER). There's ton's of info on the web, including the major drive manufacturer's sites about it.

The second factor is that the drive spindles can wear out quickly from excessive vibration when many, many drives are all chattering away in the same rack. So, some drives (WD Black for instance) are approved by the manufacturer in RAID 0 or RAID1 when there are only two drives in the enclosure. This is great news for all the two-bay NAS owners...

I see, and I remember that I've read complaints about WD's "deep error recovery" with consumer drives. Too bad, because most home users might prefer the energy efficient drives.

By the way: Thanks for the extensive review, Bruce!

Your measured power consumption on the page "insider details" (8 W in sleep mode) was with or without drives installed? In many reviews, the sleep mode consumption with discs amounts to 12-13W, which is on par with the comparable Synology DS-211+.

# Sleep ModeBruce 2011-07-24 12:14
There was one drive installed at the time I did the power measurement. In sleep mode, the drive is not spinning, that's why the power usage was lower.
