36. Supports VMware VAAI
What is VAAI?
VMware vStorage APIs Integration (VAAI) is a set of APIs
that allow ESXi hosts to offload processing for certain
storage-related services to storage systems.
Benefits:
The integration of QNAP NAS with VMware VAAI offers the
optimal performance for customers to deploy a virtualization
environment.
37. QNAP Supported Features
• VAAI for iSCSI

38. VAAI for iSCSI : Full Copy
What is Full Copy?
VAAI OFF
Enables the QNAP storage to make
full copies of data within the NAS
without needing to have the ESXi
host read and write the data.
Benefits:
• Reduces the loading of ESXi hosts
• Faster virtual machine clone
processing.

• Measured time to clone a 30 GB VM containing data (not an empty thin provisioned VM), using a normal storage and QNAP new Firmware with
VAAI.
40. VAAI for iSCSI : Block Zeroing
What is Block Zeroing?
VAAI OFF
Enables the QNAP NAS to zero out
a large number of blocks to speed up
the provisioning of VMs.
Benefits:
• Reduces the loading of ESXi hosts.
• Faster allocation of the capacity for
virtual machines.
Effective usage:

• Measured time to create a 30 GB VM with eager zero hard drives, using a normal storage.
42. VAAI for iSCSI: Hardware-Assisted Locking
What is Hardware-Assisted
Locking?
Hardware Assisted Locking enables
granular locking of block storage devices
rather than entire LUN locking in SCSI. It
provides a much more efficient means to
avoid retries for getting a lock when many
ESXi hosts share a single datastore.
Benefits:
• Permits the QNAP NAS to scale to more
VMs and more ESXi hosts w/o performance
penalty.

59. Qsync for SMB
What is Qsync?
Qsync allows users to synchronize their files between
multiple computers, and between users by sharing.
Benefits:
The use of Qsync permits to keep the latest copy of the files.
It is possible to share folders between users so that each
users can have the latest version of the files modified by
others. Ideal for collaboration!
60. Qsync for SMB
How it works?
•
•
•
•
Qsync synchronizes files in the user's Home folder.
Files remain accessible only by the user.
When a folder is shared, it becomes a Team Folder.
Team folders can be shared among multiple users.
61. Sync Files Between Different Devices
