What is Vasa VMware?

vStorage APIs for Storage Awareness (VASA) is a set of application program interfaces (APIs) that enables vSphere vCenter to recognize the capabilities of storage arrays. Such capabilities, including RAID, native thin provisioning and deduplication, are made visible within vCenter.

What is VAAI and VASA?

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.

How do I find my Vasa provider?

Check the status of VASA Provider from the virtual appliance for Virtual Storage Console (VSC), VASA Provider, and Storage Replication Adapter (SRA), and ensure that VASA Provider is active. In the VSC page of vCenter Server, verify that VASA Provider is enabled by navigating to Configuration- > Manage Extensions.

How do I register as a provider with Vasa?

Register VASA Provider With VMware vCenter

1. Start the vSphere Client and connect to the VMware vCenter Server.
2. Select View > Administration > Storage Providers .
3. Click Add.
4. Type a descriptive name for the VASA Provider in the Name field.

What does vaai stand for?

API for Array Integration
vStorage API for Array Integration (VAAI) is an application program interface (API) framework from VMware that enables certain storage tasks, such as thin provisioning, to be offloaded from the VMware server virtualization hardware to the storage array.

What is VMware Vaio?

VMware VAIO stands for “vSphere APIs for IO Filtering”. It’s a new API framework technology present in vSphere 6.0 (6.0 U1 more precisely) allowing vendors to present capabilities for caching and replication to individual VMs.

How does VADP backup work?

During VADP backups, the Virtual Server Agent requests a snapshot of the virtual machine hosted on the VMFS datastore. The snapshot VMDK and virtual machine configuration files are then copied to the storage media without requiring any dedicated disk cache on the proxy server.

What is Vasa service?

VASA Provider for ONTAP uses VMware vSphere APIs for Storage Awareness (VASA) to improve storage management between Virtual Storage Console for VMware vSphere and the vCenter Server. You can use VASA Provider to manage features such as storage capability profiles, alarms, and virtual volumes (VVols).

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.

How do I know if VAAI is enabled?

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.

What is VAAI Plugin?

The NetApp Plug-in for VMware vStorage APIs for Array Integration (VAAI) is a software library that integrates the VMware Virtual Disk Libraries that are installed on the ESXi host. You can perform tasks such as thin provisioning and hardware acceleration at the array level to reduce the workload on the ESXi hosts.

Is VMware snapshot a backup?

Do not use VMware snapshots as backups. The snapshot file is only a change log of the original virtual disk, it creates a place holder disk, virtual_machine-00000x-delta. vmdk, to store data changes since the time the snapshot was created.

What happens when Vasa request is sent to ESXi host?

When the VASA provider sends a rebind request to an ESXi host to switch the binding for a particular vSphere Virtual Volume driver, the ESXi host might switch the protocol endpoint and other resources to change the binding without any I/O disturbance. As a result, the ESXi host might fail with a purple diagnostic screen.

Why is it important to use Vasa in vSphere?

Because VASA providers enable tight integration with vSphere policy and operations management, and better troubleshooting and physical storage event correlation to reduce support costs, partners who create VASA providers are becoming the preferred storage suppliers for administrators and capacity planners seeking these optimizations.

What is the difference between Vasa and Vaai?

VMware vSphere API for Storage Awareness (VASA) VMware vSphere API for Storage Awareness (VASA) – is a set of APIs that permits storage arrays to integrate with vCenter for management functionality: Displays the features of the physical storage devices.

How are VVols exported to the ESXi host?

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.
