Datastore for VMware
• VAAI for iSCSI, VAAI for NAS
VMware vStorage APIs Integration (VAAI) is a set of APIs that allows ESXi
hosts to offload processing for certain storage-related services to storage
systems. The integration of QNAP NAS with VMware VAAI offers optimal
performance for customers to deploy a virtualization environment.

performance for customers to deploy a virtualization environment.
The QNAP NAS, VAAI iSCSI and VAAI NAS are VMware certified.
Businesses can either select 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.

• Enhanced Performance by VAAI
Storage for Microsoft Hyper-V
• ODX (Offloaded Data Transfer)
With ODX support, the QNAP Turbo NAS becomes a high performance
iSCSI storage solution under Windows Server 2012, including Hyper-V
virtualized environment. QNAP storage enables full copies of virtual
machines within the NAS without requiring the Windows hosts to read
and write the data. This highly reduces the loading of Windows hosts and
improves the performance of copy and move operations for Windows
2012 hosts using the QNAP iSCSI storage. When providing QNAP storage
to a Windows 2012 file server, the end user using Windows 8 client
workstation will also benefit from the Offloaded copy process for large
file transfers.

The QNAP Business Series Turbo NAS supports an optional 10GbE
adaptor, including SFP+ and 10G Base-T interface. The 10Gb speed
increases the agility of data transmission in a virtualized environment,
intensifying NFS and iSCSI connection performance, and enables
more VMs with multiple transactions running concurrently without
performance penalty.
