Microsoft Hyper-V and Citrix XenServer, this storage solution includes the cutting edge
VAAI for iSCSI, VAAI for NAS and ODX (Offloaded Data Transfer) technologies to
offload the heavy-duty file operations from the servers and flexible volume management
approaches, such as Thin Provisioning and Space Reclaim, to manage your volumes
more effectively. To double system performance, QNAP offers a number of network
accessories that support 10Gbe transmission speeds and the SSD Cache feature that

Se rve r Virtua liz a tion
The Turbo NAS supports three types of server virtualization applications: VMware
vSphere, Microsoft Hyper-V and Citrix XenServer. For details on each of the solutions
and supported models, check here.
VAAI for iSC SI a nd VAAI for NAS
The Turbo NAS supports VMware VAAI (vStorage APIs for Array Integration) to
increase operational performance in virtualization environments. With VAAI, data
processing is offloaded to the Turbo NAS, and standard virtual machine management
and deployment can be performed more efficiently, consuming less ESXi CPU, memory,
and bandwidth resources. VAAI includes two parts: 1) VAAI for iSCSI and 2) VAAI for
NAS.
VAAI for iSCSI supports the following four features:
F ull C opy (ha rdwa re - a s s is te d c opy ): Processes the full copies of data within the
Turbo NAS without requiring that the EXSi host reads and writes the data. This
feature can reduce the loading for ESXi hosts and speed up the cloning process for
virtual machines;
