Hardware-assisted Locking:
Enables granular locking of block storage devices rather
than locking the entire LUN in SCSI. This feature permits the VMware vSphere
environment to scale up for more virtual machines and more ESXi hosts without
performance penalty and boosts efficiency when a single datastore is shared by a number
of ESXi hosts;
Thin Provisioning with Space Reclaim:
Releases the LUN space when virtual disks are
deleted or migrated. This feature can report disk space consumption more accurately,
avoid out-of-space conditions, increases NAS space utilization and saves IT cost.
VAAI for NAS offers the following three features:
Full File Clone:
Enables the Turbo NAS to copy all data within the NAS without requiring
that the ESXi host reads and writes the data. This feature can reduce loading for ESXi
hosts, speeds up the cloning process for virtual machines.
Extended Statistics:
Enables vSphere to query space utilization details for virtual disks
on QNAP NFS datastores, including the size of a virtual disk and the real space
consumption of that virtual disk. This feature can report disk space consumption more
accurately, increase NAS space utilization and save IT cost.
Reserve Space:
Reserves the pre-allocated space of virtual disks (thick provision eager
zeroed disks) in QNAP NFS datastores. This feature can increase virtual disk read/write
performance (thin provision disks vs. thick provision disks.)
With the support of VAAI for iSCSI and VAAI for NAS, the Turbo NAS can boost storage
performance (more than 120 times faster) to create new virtual machines in a virtualized
environment. For more details on VAAI for iSCSI and VAAI for NAS, check here.
ODX (Offloaded Data Transfer)
The Turbo NAS supports Offloaded Data Transfer (ODX) in Microsoft Windows Server 2012,
making it a high performance iSCSI storage solution in Hyper-V virtualized environment.
Supporting ODX, the Turbo NAS can be offloaded with all the copying processes from
Windows servers. It highly reduces loading of Windows servers and improves the
performance of copying and moving operations for Windows 2012 hosts using the QNAP
iSCSI storage. For more details on ODX, check here.
