NVDIMM is a module integrated into the main memory of the computing platform, capable of performing the workload at dynamic random access memory (DRAM) speeds. This combines DRAM and NAND technologies, enabling data retention even when there is an unexpected power loss or system crash. The integration of these memory technologies allows NVDIMMs to achieve speed and endurance of DRAM along with the data retention characteristics of NAND flash memory. Thus, NVDIMMs are persistent memory modules with high speed and low latency.They improve performance in applications such as storage, cache, indexing, message queuing, logging, batch processing, on-line transactions, and redundant array of independent disks (RAID) applications that require higher throughput, while simultaneously offering fault-tolerant data integrity. The high performance of these devices is crucial to hyper-scale computing environments that are focused on cloud computing, big data analytics, low latency and high performance database applications. Thus, NVDIMMs are primarily aimed for huge in-memory computing tasks such as ultra-speed in-memory transactional database systems including those used in search engines and hyper-scale computing applications.
Superior capabilities offered by NVDIMMs in terms of I/O performance, latency, and data security have fueled adoption of this technology, especially in data sensitive mission critical applications. Rising demand from data centers and enterprise storage applications have fueled market momentum. In addition, formation of ‘NVDIMM Special Interest Group’ by leading vendors to accelerate penetration of the technology is expected to have positive impact on the growth of this market. However, lack of awareness regarding the benefits of NVDIMMs coupled with high cost is posing challenge to the widespread adoption of this technology. However, as the technology matures and with the development of DDR4 NVDIMM standards, it is expected to witness widespread acceptance in different verticals including, defense and aerospace, medical electronics, and consumer electronics among others.
In term of applications, market is segmented into enterprise servers & storage, high-end workstation, networking equipments and others (smart card readers, memory devices etc.). In 2014, market was dominated by enterprise servers and storage devices and accounted for over three quarters of the global NVDIMM market. Their dominance is expected to continue throughout the forecast period from 2015 to 2021. The need for non-volatile DRAM capability necessary for optimizing regular access to big data’s complicated information sets has increased the adoption of NVDIMM technology in enterprise servers and storage devices.
By end-usage industry, the market was segmented into data centers & enterprise storage, consumer electronics, industrial & automotives, medical electronics, defense & aerospace, and others. Data centers & enterprise storage was the largest end-use segment in 2014. Over the forecast period from 2015 to 2021, it is expected to remain the leading end-use segment due to growing need for ensuring data reliability, endurance, and performance in data center and storage applications where I/O performance is critical consideration and where downtime costs money.
