VMware VASA

vStorage API for Storage Awareness (VASA) is an API that enables vCenter Server to link with the storage system and obtain storage system information. VASA can be used to integrate the virtual infrastructure of the storage with VMware and to enhance the Distributed Resource Scheduling (DRS) function and the troubleshooting efficiency.

ETERNUS VASA Provider is required to use the VASA function.

ETERNUS VASA Provider obtains and monitors information from the ETERNUS DX by using functions of ETERNUS SF Storage Cruiser.

• Profile-Driven Storage

  The Profile-Driven Storage function classifies volumes according to the service level in order to allocate virtual machines with the most suitable volumes.

• Distributed Resource Scheduler (Storage DRS)

  The Storage DRS function moves original data in virtual machines to the most suitable storage area according to the access volume. Storage DRS balances the loads on multiple physical servers in order to eliminate the need for performance management on each virtual machine.
