What is VMware vaai?

What is VMware vaai?

VMware vSphere Storage APIs “ Array Integration (VAAI), also referred to as hardware acceleration or hardware offload APIs, are a set of APIs to enable communication between VMware vSphere ESXi hosts and storage devices.

How does Vaai work?

With VAAI, the Data Mover can use the API primitives to offload operations to the array if possible. Whenever a data movement operation is invoked and the corresponding hardware offload operation is enabled, the Data Mover will first attempt to use the hardware offload.

What is Vasa and vaai?

Purpose. This article defines how vStorage APIs for Array Integration (VAAI) coexists with Virtual Volume (VVol) APIs (also referred to as VASA APIs). VMware vSphere API for Storage Awareness (VASA) is a set of APIs that permits arrays to integrate with vCenter Server for management functionality.

Is vaai enabled?

How do I know if VAAI is enabled? To determine if VAAI is enabled using the vSphere Client: In the vSphere Client inventory panel, click the host. Click the Configuration tab, then click Advanced Settings under Software.

Which features are provided by the VAAI Plugin?

ETERNUS VAAI Plug-in supports three primitive of VAAI, “Full Copy”, “Block Zeroing” and “Hardware Assisted Locking”. Using this software enables functions, previously operated using server resources, to be offloaded to the storage system.

What is Vasa provider?

The VASA Provider is a critical software component of the Virtual Volumes architecture framework. While VMware develops the Virtual Volumes framework, the VASA Provider is designed and implemented by the storage vendors to support their storage solutions.

What does Vasa stand for VMware?

vSphere API for Storage Awareness
vSphere API for Storage Awareness (VASA) – VMware Program.

How do I know if VAAI is working?

How do I know if VAAI is enabled?

1. In the vSphere Client inventory panel, click the host.
2. Click the Configuration tab, then click Advanced Settings under Software.
3. Check that these options are set to 1 (enabled): DataMover.HardwareAcceleratedMove. DataMover.HardwareAcceleratedInit. VMFS3.HardwareAcceleratedLocking.

How do I disable vaai?

Disabling VAAI using the vSphere Client:

1. Open the VMware vSphere Client.
2. In the Inventory pane, select the ESXi/ESX host.
3. Click the Configuration tab.
4. Under Software, click Advanced Settings.
5. Click DataMover.
6. Change the DataMover. HardwareAcceleratedMove setting to 0.
7. Change the DataMover.
8. Click VMFS3.

How do I know if VAAI is enabled?

To determine if VAAI is enabled using the vSphere Client:

1. In the vSphere Client inventory panel, click the host.
2. Click the Configuration tab, then click Advanced Settings under Software.
3. Check that these options are set to 1 (enabled): DataMover.HardwareAcceleratedMove. DataMover.HardwareAcceleratedInit.

How do I enable vaai on ESXi?

How to Disable or Enable VAAI in ESXi Host

1. Enabling or Disabling VAAI can be perform via vSphere Client, Web Client, or PowerCLI.
2. Login to vSphere Client and access vCenter Server.
3. Click on ESXi Host.
4. Click on Configuration >> Advance Setting as shown below.

What is a VVol?

vVols are VMDK granular storage entities exported by storage arrays. vVols are exported to the ESXi host through a small set of protocol end-points (PE). Protocol Endpoints are part of the physical storage fabric, and they establish a data path from virtual machines to their respective vVols on demand.

What does Vaai do for a storage array?

VAAI’s thin provisioning enhancements allow storage arrays that use thin provisioning to reclaim blocks of space when a virtual disks is deleted, to mitigate the risk of a thinly provisioned storage array running out of space.

How is Vaai used in VMware data mover?

With VAAI, the Data Mover can use the API primitives to offload operations to the array if possible. For example, if the desired operation were to copy a virtual machine disk (VMDK) file from one datastore to another inside the same array, the array would be directed to make the copy completely inside the array.

How is the Vaai primitives used in vSphere?

Improvements in performance can be observed by timing operations that use the VAAI primitives and using esxtop to track values such as CMDS/s, READS/s, WRITES/s, MBREAD/s, and MBWRTN/s of storage adapters during the operation. In the initial VMware vSphere 4.1 implementation, three VAAI primitives were released.
