VMware vSphere APIs: Array Integration (VAAI) Introduction to VAAI This section provides an introduction to VAAI and how it provides hardware assistance to storage vendors. In a virtualized environment, storage operations traditionally have been expensive from a resource perspective. Functions such as

2025年1月15日 · What does VAAI require? VAAI requires: Standard, Enterprise, Enterprise Plus or Remote Office Branch Office licensing for ESXi hosts. Storage arrays that support VAAI storage-based hardware acceleration. How do I know if my storage array supports VAAI?

VMware vStorage APIs for Array Integration / VAAI is a set of storage array operations aimed at reducing host CPU load and storage network bandwidth. The VAAI primitives allow for offloading certain storage operations to the array itself.

Claim rules in general have always been used to implement VAAI on vSphere. VAAI is a plug-in claim rule. It says if a device is from a particular vendor, in this case a Dell PowerMax device, it should go through the VAAI filter. In other words, if VAAI can be used it is used.

2015年2月8日 · This post covers two important vSphere features: VMware vSphere API for Array Integration (VAAI) and VMware vSphere API for Storage Awareness (VASA). After reading this post, you will know answers for the following questions: What is …

2014年11月18日 · VAAI stands for VMware APIs Array Integration (for vSphere Storage). VAAI is also referred to as hardware acceleration (or hardware offload APIs), which are a set of APIs to enable communication between VMware vSphere ESXi hosts and storage devices.

VAAI is a set of APIs and SCSI commands used to offload certain functions that are performed more efficiently on the storage array, it could help reduce the consumption of network and compute resources and increase efficiency, but it doesn't always apply.

2015年2月19日 · In 2011 VMware introduced block based VAAI APIs as part of vSphere 4.1 release. This APIs helped improving performance of VMFS by providing offload of some of the heavy operations to the storage array. In subsequent release, VMware added VAAI APIs for NAS, thin provisioning, and T10 command support for Block VAAI APIs.
