Method and system for providing processor-addressable persistent memory to guest operating systems in a storage system

The non-transitory computer readable medium of 9, further comprising:

• prior to obtaining the second write request, sending memory mapping information to a client virtual machine (VM),
• wherein the memory mapping information specifies that the second set of memory segments are associated with the second memory device, and
• wherein the memory mapping information further specifies that the second memory device is not local.

The non-transitory computer readable medium of 8, further comprising:

• prior to obtaining the write request, sending the memory mapping information to the client VM,
• wherein the memory mapping information specifies that the first set of memory segments are associated with the memory device, and
• wherein the memory mapping information further specifies that the memory device is local.

The non-transitory computer readable medium of 8, wherein the write request specifies a set of virtual memory segments, and wherein the memory mapper stores a virtual memory space mapping that specifies a mapping between the set of virtual memory segments and the first set of memory segments.

The non-transitory computer readable medium of 12, wherein identifying the first set of memory segments comprises:

• analyzing the virtual space memory mapping to identify the set of virtual memory segments;
• and
• identifying the first set of memory segments based on the mapping between the set of virtual memory segments and the first set of memory segments.

The non-transitory computer readable medium of 12, wherein updating the memory mapper comprises specifying that the first set of virtual memory segments in the virtual memory space mapping are used to store the first data.
