Exxact NVDIMM High Performance Data Storage


The onboard DRAM controller triggers the backup process if a power outage is imminent. Copy data is then immediately written.


Unlike NAND flash that becomes compromised due to the oxide layer that isolates the floating gates after repeated P/E cycles.


NVDIMM is used to extend system memory or supply high-performance storage.


NVDIMM uses a familiar form factor, being able to plug into a standard DIMM connector on a memory bus.


NVDIMMs provides high performance and low latency, the flash and backup power handle data protection.


NVDIMM allows applications to continue processing I/O traffic during planned or unexpected system failures.

Combining DRAM and NAND Technology

Non-Volatile Dual In-Line Memory Module (NVDIMM) is a storage device that is able to be installed into a motherboard's DIMM slot, normally used for RAM, that stores data during a power loss, system crash, or normal system shutdown. Most NVDIMMs use NAND flash to preserve data. During a power failure or system crash, the NVDIMM module is powered by a supercapacitor pack which allows the data contained within the DRAM to be transferred to the Flash and become “persistent.”

NVDIMMs can be used to improve system crash recovery time, data security, and application performance. They are designed to benefit high performance applications including On-Line Transaction Processing, Metadata Servers storing indexes, Storage appliances, RAID caches, and other projects which are especially sensitive to down time during power failures and system crashes.

The Benefits of NVDIMM

When used in conjunction with SSDs, applications’ performance and endurance are improved substantially. Instead of depending on custom firmware or software, NVDIMMs reduce the number of write cycles for any given period and remove the need to write to the SSD. The practice of "over-provisioning" is no longer needed, increasing storage capacity available for each drive. Also, “wear-leveling” (technique for prolonging flash memory found in SSDs) is no longer necessary, which results in extending the lifecycle and subsequently increasing the return on investment (ROI) for deployed SSDs in data center applications or enterprises.

Modern file systems today utilize a transaction log based system to record changes to the file system that are not yet committed to the persistent data storage. This method safeguards the file system during out of power and any other failure situation. In the instance of a failure, the file system replays the transaction log and commits the changes to the persistent data storage, bringing the file system to a consistent state. When this occurs with conventional persistent data storage media, like hard drives, latency/ timing issues could occur. However, by using NVDIMMs as a separate logging device, the file system can respond to its clients faster and thus drastically increase the overall throughput. Because NVDIMMs are located on the memory bus, there is no need to share or interfere with the file system's I/O to its persistent data storage (on the SATA, SAS or Fiber Channel bus). Devices on the memory bus have much less latency than any device on the storage I/O bus.

NVDIMMs are the ideal solution to reduce bottlenecks and improve system performance in storage and high-reliability servers. As the next step towards the adoption of Storage Class Memory (SCM), they are leading the way to standardizing the benefits of nonvolatile random access memory.
