Samsung Semiconductor I Interview
queues, particularly beneficial for servers, which can process simultaneous disk I/O requests. In short, NVMe optimises the processor’s driver stack so it can handle the high IOPS associated with flash storage. This new relationship between bus and firmware will enable OEMs to produce faster, better and more robust servers without compromising on either their size or energy efficiency.
NVMe - the best of both worlds
SSDs on PCIe used to operate with non-standard specification interfaces. Today, manufacturers have standardised the interface, so the operating system needs only one driver to work with all SSDs adhering to that specification. The standardisation reduces complexity for SSD manufacturers who don’t need to design specific interface drivers. From the manufacturer’s point
of view, increasing standardisation gives a basis to which developers can work. Standards will also enable storage vendors to use multiple suppliers to improve performance, without the overhead of needing to support multiple drivers. Finally, from an end customer perspective, data centres will benefit from an overall increase in their servers’ performance.
The first step to V-NAND with NVMe While these 3D V-NAND and NVMe have set the wheels in motion for the flash market, many OEMs are struggling to combine the two technologies. However, Samsung Semiconductor offering both 3D V-NAND technology - after securing
300+ patents during the development phase - and NVMe. This position has provided the company with a significant advantage, enabling the organisation to focus on the development of NVMe firmware to support its existing V-NAND offering. As a result, while other market leaders attempt to catch up on the
development of V-NAND, Samsung is already launching the world’s first ‘killer app’ storage solutions (the PM1633 and PM1725), which were showcased at this year’s Flash Memory Summit.
