Turbo NAS for Business
Optimize business IT infrastructure with ease and efficiency
In addition to providing network attached storage service for file sharing, QNAP Turbo NAS is also an affordable iSCSI/IP-SAN storage solution that can be utilized as a network shared storage of the virtualization environments of small businesses. It helps achieve efficient cost-saving, energy-saving and utilization of storage capacity. Being virtualization ready - VMware® Ready™, Citrix® Ready™, and Microsoft® Hyper-V™ compatible, the Turbo NAS leverages the benefits from virtualization solutions to help IT administrators flexibly deploy and manage the virtualization environment and effectively improve work continuity.

Flexible management

Flexible iSCSI LUN target settings

As an iSCSI/IP-SAN storage solution, the Turbo NAS is capable of sharing storage capacity for multiple iSCSI targets and iSCSI LUNs over the network. It enables businesses to optimize the usage of storage capacity with disparate users within the organizations, preventing numerous storages dedicated to each user but left unused most of the time and further lowering the total cost of ownership (TCO). The Turbo NAS supports multiple LUNs mapping per iSCSI target. The LUNs can be flexibly mapped to, unmapped from, and switched among different iSCSI targets.

iSCSI LUN thin provisioning enables efficient capacity allocation

Ideally, iSCSI LUN storage capacity allocation achieves 100% efficiency when allocated amount equals to that actually used. However, in business environments, it's always not the case.

Traditionally, disk space is reserved for each workgroup when it's allocated on the first day even without any file being written. IT administrators have to be alerted when any workgroup runs out of its allocated storage capacity. This causes less flexibility for IT administrators to arrange storage capacity for the whole company.

With thin provisioning, IT administrators are able to over-allocate the iSCSI LUN capacity for each workgroup regardless of the physical storage limit. The physical disk space is used only when files are written.

The implementation of thin provisioning ensures the disk space is fully utilized with the growth of businesses. IT administrators only need to watch the total storage capacity actually being used by the whole company, and expand the capacity when it runs out. When storage capacity expansion is needed, the Turbo NAS provides "online RAID capacity expansion" and makes sure zero system down time.

User Manual Application Notes

Secure deployment

Secured by CHAP authentication and LUN masking

Security can never be overemphasized in the networked environment. The Turbo NAS supports CHAP authentication and advanced Access Control List (ACL) to enhance the security of data transmission over the network. Besides, secure deployment can be achieved via the LUN access control. With the function of LUN masking, IT administrators can specify the access rights of the initiators to each LUN and prevent the risks from unauthorized access.

User Manual

Designed for virtualized and clustered environments

SPC-3, MPIO and MC/S support

The SPC-3 support for clustered environment deployment enables IT administrators to quickly execute live migration for virtual machines. The MPIO (Multipath Input Output) and MC/S (Multiple Connections per Session) support allows IT administrators to connect to the iSCSI targets on the Turbo NAS using two or more network interfaces from the server with failover and load balancing and achieve enhanced data transmission performance.

Shared storage for virtualization environments

The Turbo NAS is certified with VMware vSphere NFS and iSCSI protocols, Citrix XenServer, and is compatible with Microsoft Hyper-V environment, making the Turbo NAS to be easily deployed as a shared storage in a virtualized testing environment where users need to run different types of operating systems and software applications.

VLAN support for separate data transfers

The Turbo NAS is designed for virtualized and clustered environments, and supports virtual LAN (VLAN) connection to form an isolated network. For organizations, different VLANs can be created for different groups separately, and users in one VLAN are not able to access another. Since each VLAN is isolated from one another and thus it effectively separates data transfers to each VLAN for a better management and security.

Complete backup solution

The Turbo NAS plays an important role in providing the backup solution. It can be utilized for backing up data from physical computers and virtual machines to achieve data protection and disaster recovery. The Turbo NAS has taken iSCSI LUN backup/restore to a whole new level with snapshot technology.

Protection by iSCSI LUN snapshot

Directly backing up an iSCSI LUN usually takes a long time. In addition, during backup a LUN usually continues to provide data access; this could cause backed up contents to be inconsistent with the original copy. The Turbo NAS provides LUN snapshot to overcome this. A snapshot uses little time to record the current LUN status, just like taking a picture. IT administrator can further use the LUN snapshot to back up, restore, or allow access to the contents in the LUN, while it is still being used.

LUN backup and restore

A LUN snapshot has the LUN state when the snapshot was taken.IT administrators can use the LUN snapshot to back up contents in the file-based LUN and block-based LUN to various storage destination, including Windows shared folders via SMB/CIFS, Linux shared folders via NFS, or simply local shared folders on the Turbo NAS. Instant and scheduled backup options are available. In the event of LUN failure, IT administrators can choose to restore the LUN by overwriting the original one or creating a new LUN.

LUN snapshot access granted to other users

Since a LUN snapshot has the LUN state at a certain time, when users need to obtain contents at that point of time, the IT administrators can mount the snapshot to an iSCSI target on the Turbo NAS to allow data access from users.

VAAI support

New virtualization experience

VAAI for iSCSI and VAAI for NAS

The Turbo NAS supports VMware VAAI (vStorage APIs for Array Integration) to increase the performance for operations in virtualization environments. With VAAI, data processing is offloaded to the Turbo NAS, and standard virtual machine management operations and deployment can be performed faster, using less ESXi CPU, memory, and bandwidth.

VM' Write Read



The Turbo NAS supports VAAI for iSCSI and VAAI for NAS. VAAI for iSCSI supports Full Copy (hardware-assisted copy), Block Zeroing (hardware-assisted zeroing), Hardware-assisted Locking, and Thin Provisioning with Space Reclaim. VAAI for NAS supports Full File Clone, Extended Statistics, and Reserve Space.

The Turbo NAS, with the support of VAAI for iSCSI and VAAI for NAS, increases storage performance more than 120 time faster to create new virtual machine in a virtualized environment.

vSphere Client plug-in

The Turbo NAS supports vSphere Client Plug-in. Administrators can easily control the status of the Turbo NAS and datastores and create additional datastores to multiple ESXi hosts in just a few clicks from the vSphere client console. In a large-scale server virtualization environment, management becomes centralized and straightforward.

With the support of vSphere Plug-in v1.3, the option to create a datastore on a dedicated volume is available to provide better flexibility. The process is a one-step effort since the volume creation is automatically done when creating a datastore. Management process is remarkably simplified.


Hyper-V support

ODX(Offloaded Data Transfer)

The Turbo NAS supports Offloaded Data Transfer (ODX) in Microsoft Windows Server 2012, becoming a high performance iSCSI storage solution in Hyper-V virtualized environment.

The Turbo NAS supporting ODX can offload the copy process within the NAS without requiring the Windows Server to read and write the data. It highly reduces the loading of Windows servers and improves the performance of copy and move operations for Windows 2012 hosts using the QNAP iSCSI storage.
