"In a virtualized environment, storage operations traditionally have been expensive from a resource perspective. The VMware vSphere Storage APIs - Array Integration (VAAI) supports a set of ESXCLI commands for enabling communication between ESXi hosts and storage devices. Using this API/CLI has several advantages. This paper focuses on one component of those APIs known as VMware’s Storage APIs for Array Integration (VAAI Array Thin Provisioning APIs. VAAI とも呼ばれるこれらの API には、次のコンポーネントが含まれています。 ハードウェア アクセラレーション API。vSphere にアレイを統合して、特定のストレージ操作をアレイに対してオフロードできるようにします。

Storage APIs - Array Integration, formerly known as VAAI, include the following APIs: Hardware Acceleration APIs. Functions such as cloning and snapshots can be performed more efficiently by the storage device than by the host. We use cookies for advertising, social media and analytics purposes. In vCloud environments, cloning and snapshot operations stemming from provisioning tasks can quickly overwhelm the system. See Storage Hardware Acceleration.

See Using Storage Providers. vStorage APIs for Array Integration (VAAI): 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 . From vSphere 4.1 a new set of vStorage API has been added: vStorage APIs for Array Integration (VAAI). Using this API/CLI has several advantages. Allows arrays to integrate with vSphere to transparently offload certain storage operations to the array. This will help administrators determine whether VAAI is working correctly in their respective environments.

The APIs define a set of storage primitives that enable the ESXi host to offload certain storage operations to the array. Help to monitor space use on thin-provisioned storage arrays …

From vSphere 4.1 a new set of vStorage API has been added: vStorage APIs for Array Integration (VAAI). For others vStorage API see this diagram: The VAAI can offload specific storage operations to compliant storage hardware, which results in less CPU, memory and storage fabric bandwidth consumption.

This integration significantly reduces CPU overhead on the host. The VMware vSphere Storage APIs - Array Integration (VAAI) supports a set of ESXCLI commands for enabling communication between ESXi hosts and storage devices. Unterstützende Arrays für die Integration in vSphere, sodass vSphere bestimmte Speichervorgänge auf das Array auslagern kann. Help arrays to integrate with vSphere, so that vSphere can offload certain storage operations to the array. VMware vSphere Storage APIs is a family of APIs used by third-party hardware, software, and storage providers, such as Dell EMC, to develop components that enhance several vSphere features and solutions.

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. This section describes some of the options available for fine-tuning and monitoring the VAAI primitives. vSphere APIs for Array Integration.
