Distributed integrated high-speed solid-state non-volatile random-access memory
First Claim
1. A storage system comprising:
- a plurality of embedded storage devices, wherein each embedded storage device of the plurality of embedded storage devices comprises;
a first direct-mapped solid state drive (SSD) storage portion, wherein the first direct-mapped SSD storage portion has erase blocks mapped as directly addressable storage of the SSD; and
a second non-volatile random-access memory (NVRAM) portion comprising a random access memory (RAM) device and a processing device, wherein the first direct-mapped SSD portion and the second NVRAM portion are separately addressable, and wherein the second NVRAM portion is smaller capacity than the first direct-mapped SSD portion; and
a plurality of storage system controllers, operatively coupled to the plurality embedded storage devices via a bus, the plurality of storage system controllers to;
determine that data is to be stored in the first direct-mapped SSD storage portion of a first embedded storage device of the plurality of embedded storage devices; and
buffer the data in the second NVRAM portion of a second embedded storage device of the plurality of embedded storage devices.

Abstract
A system may include embedded storage devices, each including: a first solid state drive (SSD) storage portion and a second non-volatile random-access memory (NVRAM) portion. The NVRAM portion includes a random access memory (RAM) device, a processing device, and an energy source, where the first SSD portion and the second NVRAM portion are separately addressable. The system further includes a storage system controller, operatively coupled to the embedded storage devices via a network. The storage system controller may be to: determine that data is to be stored in the first SSD storage portion of a first embedded storage device of the plurality of embedded storage devices; and buffer the data in the second NVRAM portion of a second embedded storage device of the plurality of embedded storage devices.
