VMware, Inc.
Direct access flash transition layer

Abstract:

The disclosure provides an approach for accessing data stored in a page addressable memory by a first virtual computing instance (VCI) running on a host, the host running a virtualization layer configured to provide access to resources to the first VCI. The approach includes mapping by a flash translation layer (FTL) of the virtualization layer a first virtual address received in an I/O request from the first VCI directly to a physical page address (PPA) of the page addressable memory. The approach includes issuing an access request to the page addressable memory based on the I/O request, the access request comprising the PPA. The approach includes receiving data stored at the PPA from the page addressable memory. The approach includes passing the data to the first VCI.
