Marvell releases firmware +longsys deep development, focus on customization and industrial application of SSD


In the storage market, core technology of chips is in the hand of international large manufacturers. Supply of NAND Flash is monopolized by several large enterprises such as Samsung, Toshiba, Micron, SK Hynix and Intel. SSD is one of products deliberately planned by several original manufacturers. How does longsys face the competition from original manufacturers and improve its competitive power?


Zhong Mengchen, product manager of longsys, said, “We are now focusing on SSD which is also in the business range of original flash manufacturers but we can always find our market eventually. For example, storage capacity of SSD produced by original flash manufacturers is at least 128GB; however, many industrial clients need small capacity such as 64GB and 32GB, quantity demanded is not so big and they even require customization and fast delivery. Flash manufacturers are not willing to touch this partial market. We are also communicating some detailed customization with some internet enterprises now. Flash manufacturers can not meet these market requirements on some special products.”


Zhong Mengchen also expressed that Marvell released longsys with source code to let longsys develop its own firmware. Apart from constructing high-quality, high-performance, safe and reliable SSD products, it is convenient for longsys to offer products that suit the market, satisfy the demand on customization, and maximize the application of SSD.


Mick Chen, marketing director in SSD business division of Marvell expressed as well that the reason why Marvell cooperated with longsys was that longsys had made much accumulation and laid a good foundation in the market and moreover longsys was a company that paid much attention to thinking, got close to clients and supported them. In general, longsys had the capability of independent research and development. All these made longsys a good choice as cooperative partner.


Zhong Mengchen said,” some of our industrial clients want thorough customization openness but the openness has certain limitation. We can provide clients some interfaces for them to get the access to data below and operate at the bottom layer. These can be realized by virtue of technologies possessed by longsys and controller of Marvell. For example, we can customize some private functions and make some additional applications that they want.”

With Marvell controller support ,longsys is walking the forefront of SSD market  from SATA to PCIe


Market popularity of SSD SATAIII is basically realized now. In future, SSD interface is to develop from SATAIII to PCIe interface.


Mike Chen makes an analysis from three aspects about the development of SSD to PCIe.


In the first place, it is about the impetus of market requirement. Users’ requirement on speed is improving unceasingly.


In the next place, PCIe ecological chain has gradually formed. CPU on Intel Skylake platform adds PCIe NVMe channel and other manufacturer of ecological chain will also enhance support for PCIe interface.


Last but not least, from the aspect of price, there is huge difference between prices of SSD PCIe and SSD SATA. SSD PCIe mutually launched by Marvell and longsys is close to the cost of SATA. Advantage in price is the largest driving force for transferring to PCIe.


Well, will SATA SSD get fully replaced by PCIe SSD? It depends on the manufacturers’ support for SATA. As long as SATA interface exists, SATA SSD exists. However, it is easy for SATA interface to get velocity saturation. Any system pursuing efficiency will switch to PCIe soon.


With the advantage in technological innovation, longsys launched 2D TLC SSD based on DRAM-less structure first without any fear of price war.


In the trend of rapid growth of SSD, more and more enterprises will come in while users in commercial market care more about price so it is easy for product competition to get into price war.


Regarding this market phenomenon, Li Zhixiong, general manager of Longsys quoted what a tech star in Taiwan said that one of the most obvious expression of high-tech products was low cost. Everything was becoming much cheaper. It was important to lower the cost when enterprises were dealing with high-tech products.


Actually it is unnecessary to worry about low cost because it is exactly low cost that makes SSD become more popular. Laptops equipped with SSD in the market now takes up 25% and the figure will reach 40% to 50% in 2016. Especially two-in-one laptops and ultrabooks all adopt SSD.


How to face low cost? Li Zhixiong made an analysis.


First, latest 28nm technology possessed by Marvell has the advantage in technology.


Next, Marvell DRAM-less NVMe SSD controller optimizes the cost. Because of less of one Dram chip, packaging becomes much easier and PCB board is not complicated any more so that cost is naturally lowered.


Last, Marvell adopts LDPC technology. Traditional BCH has limited ECC capability. LDPC goes through loop iteration to eliminate more errors. This technology has been utilized in communication field for several decades and it transfers to NAND Flash application gradually. Our TLC SSD benefits from the support from 28nm advanced technology possessed by Marvell and it has lower cost comparing with MLC SSD.

When it comes to the development of TLC SSD in the market, Zhong Mengchen said, “Our TLC SSD is mainly applied in retail market of PC OEM market. TLC SSD is not applied in industrial market at present. Industrial applications have their particularity. For example, MLC SSD is a better choice for vehicle-mounted DVR because video is recorded and SSD is written everyday.”


Our fist step of plan will be in the retail market. The second step is to make publicity and promotion in PC OEM market. The third step is to generalize TLC SSD among industrial or business clients whose master demand is read application.


Marvell cooperates with longsys in security market and plans to stride forward data center market with huge potential.


Now the country is advancing the construction of information safety. Besides, there is a huge demand on the storage of BAT internet cloud data and center storage of server data. Thus, SSD will be a key application.


Zhong Mengchen expressed that the government and army had some requirements on data security because they wanted put an end to conditions such as data loss and leakage. Marvell released the bottom interface of SSD main-controller to longsys so longsys could develop firmware algorithms and protocols suitable for national and governmental security projects on this basis (longsys is the national fixed unit for the production of commercial encryption products) to get rid of risk in backdoor software and improve the security of data. In addition, regarding the SSD assembly house in Suzhou, right of supervision on production could be given appropriately according to the requirement of clients and other related institutions.


Moreover, Marvell has a rich experience and favorable reputation in enterprise-level data center market, which is of help to the fast growth of longsys. Enterprise-level data center market is also one of strategic investment directions for longsys.
