System and method for non-volatile random access memory emulation

A method for emulating a non-volatile random access memory (NVRAM) for a storage system, the method comprising:

• using computer hardware for performing:
• receiving a storage capacity value of a volatile random access memory (RAM) device to indicate an available storage capacity of the volatile RAM device;
• allocating a range of a primary storage device, wherein a capacity of the allocated range of the primary storage device is based on the storage capacity value of the volatile RAM device;
• storing data to the allocated range of the primary storage device;
• migrating data from the allocated range of the primary storage device to the volatile RAM device;
• and
• migrating data from the volatile RAM device to the allocated range of the primary storage device in response a status of the volatile RAM device.

A non-transitory computer readable medium carrying one or more instructions for emulating a non-volatile memory for at least one storage system, wherein the one or more instructions, when executed by one or more processors, causes the one or more processors to perform the steps of:

• receiving a value indicating a number of primary storage devices, each primary storage device comprising an allocated range;
• segmenting a volatile random access memory (RAM) device into a plurality of segments, the segmenting based on the value indicating the number of primary storage devices;
• assigning each segment of the volatile RAM device to one primary storage device, each primary storage device is assigned to one segment of the volatile RAM device;
• and
• migrating data from the allocated range of each primary storage device to the corresponding assigned segment of the volatile RAM device.

A system, comprising at least one processor and memory, for emulating a non-volatile memory for at least one storage system, the system comprising:

• a non-volatile random access memory (NVRAM) emulation engine configured for:
• receiving a value indicating a number of primary storage devices, each primary storage device comprising an allocated range;
• segmenting a volatile random access memory (RAM) device into a plurality of segments, the segmenting based on the value indicating the number of primary storage devices;
• assigning each segment of the volatile RAM device to one primary storage device, each primary storage device is assigned to one segment of the volatile RAM device;
• and
• migrating data from the allocated range of each primary storage device to the corresponding assigned segment of the volatile RAM device.
