In the data center and related environments, high-end systems are struggling to keep pace with the growing demands in data processing.
There are several bottlenecks in these systems, but one segment that continues to receive an inordinate amount of attention, if not part of the blame, is the memory and storage hierarchy.
SRAM, the first tier of this hierarchy, is integrated into the processor for cache to enable fast data access. Then, DRAM, the next tier in the hierarchy, is used for main memory. And finally, disk drives and NAND-based solid-state storage drives (SSDs) are used for storage.
