vStorage APIs for Array Integration (VAAI) is provided in "VMware vSphere" which enables platform virtualization. VAAI is an API which improves system performance and scalability by making effective use of the resources of ETERNUS AF/ETERNUS DX (herein after called ETERNUS). ETERNUS support the following functions of VAAI.
Previously, it is required to copy data through a server for replication of virtual machine, data migration, etc. This function enables data copy within a ETERNUS without going through the server. This reduces load on the server and improves system performance.
When allocating storage area to create a new virtual machine, etc., it is necessary to zero out the storage area as initialization process. Previously, this process is performed at the server side. Performing this process at the ETERNUS side instead reduces load on the server and speeds up capacity allocation of virtual machine.
When writing to virtual server disk volumes the logical volume locking size in VMware vShere environments is large. This means subsequent writes to the same area have to wait for the first one to finish. By performing exclusion control at the ETERNUS storage level uses much smaller block unit sizes. This improves the operational efficiency of the overall virtual machine environment.
Unallocated areas created by file or virtual machine deletion can be released. They are released by issuing a UNMAP command or deleting a file on VMFS. They are not released by file deletion by the OS of a virtual machine.
A host notification function notifies the host when the number of primary allocated blocks reached its threshold value.

ETERNUS VAAI Plug-in is required to use VAAI in any of the following environment. (Please ask our sales representative for downloading of the ETERNUS VAAI Plug-in.)
For example, ETERNUS VAAI Plug-in is NOT required for VAAI support if only ETERNUS DX S2 series with firmware version V10L20 or later is used in vSphere 5 environment.
