Unified Storage Management

QNAP's Turbo vNAS business series is an unified storage system which can serve as iSCSI SAN storage and Turbo vNAS. The powerful Storage Manager can assist you manage iSCSI LUNs and volumes efficiently.

Intelligent Storage Manager
The QTS 4.1.2 Storage Manager neatly presents tools and options for managing system storage with an intuitive graphical interface. Pools, disks and iSCSI storage, the Storage Manager provides a centralized place to easily manage different hard drives (e.g. SAS HDD and SATA HDD) and to maximize storage usage of the tiered and unified storage.

Dashboard
The Storage Manager dashboard presents an overview for IT administrators to easily check the storage allocation status. QTS 4.1.2 provides a more secure and flexible way to store and manage the NAS data. This next generation volume offers powerful features such as storage pooling with multiple RAID groups, thin provisioned volumes with space reclamation, and online capacity expansion. Just click "New Volume" and you can start to allocate capacity.

	HDD Management IT administrators can view the HDD information to check the HDD allocation status for RAID group. With the information, it can be ensured that there is no idle HDD for the maximized utilization of the storage resources.
	Storage Pool IT administrators can aggregate multiple RAID groups into a big storage pool to flexibly utilize the storage capacity as a whole, protect them using redundancy and allowing for better protection against multiple disk failures for large-capacity environments. Multiple volumes can now be created on the Storage Pool to provide flexible deployment.
	Flexible Volume Allocation QTS 4.1.2 allows creating multiple volumes on the Storage Pool for various applications in typical business environments with different workgroups. Each data volume and LUN can be extended without interrupting services.

iSCSI LUN
QTS 4.1.2 supports two types of LUNs for efficient storage utilization: block-level and file-level iSCSI LUNs. The Turbo vNAS also supports multiple types of configurations for server connections:

• single LUN or multiple LUNs per iSCSI target.
• multiple iSCSI targets for a single LUN, only used for clustered environments

Block-Level iSCSI LUN
Besides storing data, volumes can be utilized as an iSCSI LUN. The block-level iSCSI LUN provides less overhead which improves the overall read/write performance.

File-Level iSCSI LUN
Users can consider file-level iSCSI LUNs if there isn't enough space for block-level iSCSI LUNs. The file-level iSCSI LUN can be used for creating a disk image for an iSCSI LUN.

Virtual Disk Drive - Increase flexibility of storage expansion
Virtual disks provide a more flexible way for IT administrators to expand storage. By using the built-in iSCSI initiator to connect an iSCSI target of the Turbo vNAS, you can create a virtual disk on the local server. The Turbo vNAS can be a stack master to connect up to 8 virtual disks or stack targets, aggregating storage space from multiple NAS systems. Thus, all NAS users only need to connect to a single target to access the space from all of the network storage devices.

QNAP high-performance unified and tiered storage solutions
Data used by enterprises continues to grow exponentially and with greater diversity in data types and importance. It is imperative to offer a secure and efficient storage solution that can process this enormous amount of data while minimizing the total cost of ownership.

Establishing a tired storage system based on efficiency and capacity can aid in improving overall processing efficiency. Enterprises can classify data accordingly by sharing folders with a file-based storage system and processing files that require more demanding data throughput with a block-based storage system to accommodate different usage models.

QNAP Turbo vNAS business series can flexibly configure different tiers to hard drives on a single unit according to different data usage needs, delivering the best unified and tiered storage solution.

Tiered storage for better efficiency
In the cloud era, enterprises need a storage architecture that can provide rapid access to dynamically scalable and virtualized IT resources. Classifying data into Hot Data (frequently-accessed) and Cold Data (rarely-accessed) to store them in a tiered storage can help achieve this goal efficiently and cost effectively. Businesses often use SSD to improve the overall workflow of random IOPS demanding applications such as databases and virtualization. Different types of storage media are used for different purposes. Hence, it is better to utilize different storage media according to the system requirements.

QNAP's Unique Transcoding Technology

Every year many SMBs produce hundreds of promotional videos for marketing purposes. However, due to the increasing use of HD videos (720p, 1080p), video files are becoming increasingly large in size and can use lots of network bandwidth to share or play them over a network.

Transcode Management
With the popularity of high-definition smartphones and digital cameras, video resolutions are getting higher. A higher resolution means larger file sizes and more bandwidth needed to stream it. Transcoding creates videos with optimal resolutions for sharing & watching in order to save bandwidth, but also retains the unaltered original video on the Turbo vNAS.

Smart transcoding adapts to suit different bandwidth
The TVS-x71 Series provides a range of resolutions to play/share videos according to different bandwidth limits. Higher resolutions need more bandwidth, and you can select the right resolution for your network environment to get the best viewing experience.

Multi-mode transcoding function

• Background hardware-accelerated transcoding
  The TVS-x71 fully supports offline background transcoding for 4K (H.264) videos. Just add videos to the transcoding list and use the Turbo vNAS to convert the original high-resolution video for use with multiple resolutions. Then you can select an appropriate resolution when sharing or watching to match your device or network environment.
• Auto transcoding
  When you set a folder on the Turbo vNAS to be an autotranscoding folder, videos added to it will be automatically converted to a resolution you have set. For example, if you set the folder to 360p, videos added to this folder will be automatically transcoded to 360p as a background task.
• On-the-fly transcoding
  If you have many high-resolution videos, but did not transcode in advance, you can use on-the-fly transcoding. This will adapt to meet bandwidth limits, with the Turbo vNAS transcoding in real time for directly watching the video.
• Embed subtitles
  By selecting the Embed Subtitles option in the Transcode Management function, you can embed subtitles to a video when converting a video to any resolution. The subtitles will then be displayed when a video is played on whatever device you are using.
• Hardware-accelerated transcoding technology
  With Intel HD Graphics, video creation & conversion is faster, easier and can significantly reduce the time needed when handling multiple on-the-fly transcoding tasks.
• Performance
  Compare the transcoding time between the TVS-671-PT and TS-670 with using the same high-resolution (1080p) video. Powered by an Intel Pentium CPU with QNAP's exclusive transcoding technology, the TVS-671-PT is 16 times faster than the Celeron-based TS- 670.

Qsync

Synchronize files anytime, anywhere
Qsync is a useful tool to synchronize files in multiple computers. It creates a specific “Qsync folder” in your devices that you can simply drop files in, and synchronizes the files to all your devices linked to the Turbo NAS.

Sync in multiple ways

Full Sync
Whenever you add, edit, delete or rename a file on one computer, the change applies to all others linked with the Turbo NAS, so you have exactly identical contents on all your devices.

Smart Sync
It allows you to remove files on one computer without affecting the copies stored on others that are linked with the Turbo NAS. However, when someone updates the files you deleted from another computer, you can still retrieve them in the Qsync folder.

Advanced Selective Sync
With both Full Sync or Smart Sync options, you can choose to only sync specific sub-folders within the Qsync folder, useful if your computers have limited storage.

Share files and folders easily

Quickly share files with download links
You can create download links to share files with people, even if they don’t have an account on the Turbo NAS. This greatly reduces the time in creating user account and password for users.

Share folders for collaboration
Your life is connected with different groups of people. You can create sub-folders within the Qsync folder, and share each with different groups of Turbo NAS users as a file exchange center. Everyone in the same sub-folder is always kept up-to-date with the latest version of the files.
