VAAI for iSCSI, VAAI for
NAS
The QNAP NAS, VAAI iSCSI and VAAI NAS are VMware
certified. Businesses can select either iSCSI or NFS as
a centralized storage to boost performance. 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 QNAP NAS supports VAAI iSCSI and
VAAI NAS to enhance storage performance in a virtualized
environment.
￭ Storage for Microsoft
Hyper-V
With ODX support, the QNAP Turbo NAS becomes a
high-performance iSCSI solution under Windows Server
2012 , including Hyper-V virtualized environments. QNAP
storage enables full copies of virtual machines within
the NAS without requiring the Windows hosts to read
and write the data to highly reduce the load on Windows
hosts and improving the performance of copy & move
operations on Windows
2012 hosts. When providing
QNAP storage to a Windows
2012 file server, the end user
using a Windows
8 client workstation will also benefit
from the Offloaded copy process for large file transfers.
￭
vSphere plug-in
The vSphere plug-in allows users to manage the QNAP
Turbo NAS directly on the vSphere client, making datastore
management more effective.
￭
NAS management via
SCVMM
QNAP SMI-S enables management of the QNAP Turbo
NAS directly through Microsoft System Center Virtual
Machine Manager
2012 (SCVMM)
