PMC flashtec? NVRAM flash accelerator FAQ

Summary

PMC flashtec NVRAM flash accelerator series is a PCI-Express based on the most advanced nvme controller on the market today? NVRAM solution. This series of products sets up a new storage level to accelerate key applications.

SSD solutions constantly replace the traditional HDD in the high-performance hierarchy of multi-level storage space. However, there is also a huge performance gap between the memory and storage layers in terms of latency, durability, and high availability. As application requirements continue to increase with the speed of cloud services, the result of relying on the volatile memory to achieve the required performance is that data loss required by applications may occur in the case of system faults.

We need a new level of storage layer to provide necessary data security protection for key task-based applications, while also ensuring the performance required by applications, there is no need to sacrifice data protection, reliability and availability. The flashtecnvram flash accelerator series meets this requirement. A single card can provide over 10 million iops and 16 GB capacity, thus meeting the most stringent application requirements.

Products and features

What is performance?

The NVRAM flash acceleration card establishes a new storage level between DRAM and PCIe SSD, featuring excellent performance and high reliability. Its features include:

• It also has DRAM write resistance and non-volatile features of NAND.
• In direct connection storage mode, iops reaches 10 million times; in nvme block (4 kb) mode, iops reaches 1 million times; performance is increased by 10 to 100 times over SSD
• Latency lower than the level of granularity

Which application is this solution designed?

The flashtecnvram flash accelerator is designed for mission-critical applications that require high performance and reliability, including:

? Write cache with high latency requirements

? Persistent metadata storage area of a 64-bit addressing space

? Persistent shared memory in a horizontally extended cluster system

? High-Performance Logs or transaction commit logs

? Persistent cache required for high-speed cache Reconstruction

? High-performance storage layer on top of the Low-performance storage layer

As the ecosystem continues to evolve, this series of products will be integrated into many other systems in the future.

What is the product size?

Half-height md2 PCIe insertion card

What modes does this product support?

This series of products can be used as an extension of persistent storage mapped directly to hosts (random small access can achieve tens of millions of iops ), it can also be used as an nvme block device for efficient DMA transactions (4 k B sustained random read iops more than 1 million times)

When will this series of products be available?

The customer has provided a sample card for evaluation. Mass production is expected to be put into operation in the later stage of 2014 q4.

Customers, markets and trends

 What is the difference between this product and PCIe SSD or NV-DIMM?

PMC combines DRAM with flash memory to perfectly meet the performance requirements of the storage system required for the most critical applications. Flash memory itself does not have durability, while DRAM itself is not reliable enough for mission-critical data. The result of combining the two is the performance of 10 ~ 100 times higher than any SSD on the market.

The limitations of flash storage devices are the durability, which is fundamentally derived from the durability of their internal NAND Flash technology-usually no more than 10,000 programming/erasure times. In contrast, the dram used by the flashtec NVRAM flash accelerator card basically has no durability limitations, which is exactly what this product can do.ContinuousProvides the reason for millions of writes per second. None of the NAND Flash-based solutions can achieve this.

Compared with NV-DIMM technology, PMC's flashtec NVRAM flash accelerator series are based on industry-standard (nvme standard for PCIe interfaces), so it has the advantages of easy integration from the hardware and application perspective. On the DDR bus, the CPU must process the transmission of each data transaction. Pmc nvram flash memory accelerator uses the PCIe DMA engine, the CPU does not need to transmit data, so the CPU can be freed from application processing, and finally achieved four times the CPU utilization of the NV-DIMM.
