New Virtualization Experience

New Virtualization Experience

• VMware vSphere– Supports VMware VAAI – QNAP vSphere plug-in

• Windows Hyper-V– Supports ODX (Offloaded Data Transfer)– SCVMM– Thin Provisioning– Certified for Windows 2012

QNAP for VMware vSphere

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.

QNAP Supported Features

• VAAI for iSCSI– Full copy (hardware-assisted copy)– Block zeroing (hardware-assisted zeroing)– Hardware-assisted locking– Thin provisioning and space reclaim

• VAAI for NAS– Full file clone– Extended statistics– Reserve space

Note:1. Firmware 4.0.4 or above is required.2. Visit the QNAP virtualization features page for supported NAS models and more details.

VAAI for iSCSI : Full Copy

What is Full Copy?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.

Effective usage: • vCenter Cloning• Storage vMotion• Deploy VMs from templates

Test environments and verification steps:• TS-EC1279U-RP, 12* Seagate ST3000DM001-9YN166 (SATA), RAID 6• 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.

VAAI for iSCSI : Block Zeroing

What is Block Zeroing?

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: • Create Thick Provision Eager

Zeroed virtual disks.• Write data to Thick Provision Lazy

Zeroed virtual disks.

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.

Effective usage: • Power on VMs• Create VMs or templates• Create VMFS datastores• …. and more

VAAI for iSCSI : Hardware-Assisted Locking Performance

Performance verification steps:

1. Create a virtual machine (VM1) on the ESXi host 1, and use IOmeter to generate I/O load on iSCSI datastore.

2. Create 16 virtual machines (VM2 to VM17) on another ESXi host 2 and perform the virtual machine power ON operations simultaneously.

3. Record the throughput of the VM1.

What is Full File Copy?Similar to the Full Copy in iSCSI, it 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.

Effective usage: • vCenter Cloning• Storage vMotion (cold clone)• Deploy VMs from templates

VAAI for NAS: Extended Statistics

What is Extended Statistics?Enables vSphere to query space utilization details for virtual disks on QNAP NFS datastores. This includes the size of a virtual disk and the real space consumption of the virtual disk.

Benefits:• More accurate reporting of disk space consumption.• Increased NAS space utilization and save $.

VAAI for NAS: Reserve Space

What is Reserve SpaceHistorically, vSphere only supported building thin virtual disks on NFS. By supporting the Reserve Space, a space pre-allocated virtual disk (thick provision eager zeroed disk) is possible in QNAP NFS datastores.

Benefits:• Better virtual disk read/write performance (thin provision disks v.s. thick provision disks)

Qsync for SMBs

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!

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.
