[TechWeb] April 18, Puneet Sharma, Senior Director of non-volatile memory (NVM) Product Management, Micron embedded products Division, released a signed article entitled “how the world’s first four-port SSD will drive smart car architecture change”.
This paper makes an in-depth introduction to the role of Meguiar 4150AT SSD vehicle storage in promoting the reform of intelligent vehicle architecture.
According to the data, Puneet Sharma is responsible for managing the NVM portfolio, including UFS, eMMC and SSD products for the automotive, industrial and consumer markets.
Over the past 18 years, Puneet Sharma has accumulated rich experience in NAND design, fab integration and application engineering.
So far, he has obtained 18 US and international patents.
The following is the full text of “how the world’s first four-port SSD will revolutionize smart car architecture”: cars are becoming a “data center on wheels”, a title made more apt by innovations in advanced features and computing architecture.
Smart cars, for example, are by far the most complex software-driven machines, running about 100 million lines of code, and with the rise of AI in cars, that number is expected to climb to 1 billion lines soon.
However, the problem is that the current automotive architecture design is not enough to support the explosive growth of data, the current automotive architecture and storage systems need to be improved.
So what should be done? Today, cars are moving from a traditional domain distributed architecture to a partition architecture, simplifying design through centralized decision-making.
In fact, McKinsey predicts that by 2030, the proportion of cars using zoning will reach about 18% and will continue to grow.
Within the existing domain architecture, in-vehicle systems are grouped according to their functions, such as in-vehicle infotainment system (IVI), connection, powertrain and so on.
Although this approach was once feasible, as car systems become more complex, the number of sensors, cameras and electronic devices is growing exponentially, with some cars having as many as 150electronic control units (ECU).
This makes the line layout more complex and onerous, increasing the cost and body weight.
The partition architecture simplifies the connection of electronic devices by effectively grouping systems and devices in the physical area near the electronic controller (ECU).
Local controllers in these areas are connected to a central high-performance computer cluster similar to data center servers, and high-end cars can be equipped with up to four system-on-a-chip (SoC).
At present, many new models have been planned to adopt this centralized architecture, but the existing vehicle storage solutions are not enough to support so many SoC, it is difficult to achieve the ideal system efficiency.
, , in order to solve the above problems, we have launched a new model of automotive storage-Meguiar 4150AT SSD.
This SSD not only provides the flexibility and scalability of the data center SSD, but also extends the dual-port capabilities common in the data center, is the first four-port SSD on all end markets, and integrates powerful single input / output virtualization (SR-IOV) capabilities.
These groundbreaking product features will drive the automotive industry to shift to centralized architecture design, resulting in better intelligence and safety performance.
Let’s understand the principle and motivation together.
The integration of SSD, multi-port SSD and SR-IOV technology, specially built for the new era of smart cars, provides a powerful solution for managing data isolation and data sharing at the same time.
Each port of the 4150AT SSD can be connected to the SoC and can support up to 16 virtual machines (VM), providing precise control of data access.
The four ports of 4150AT SSD provide multiple independent data channels that can communicate with the host system at the same time.
These ports can be assigned to support different virtual machines or workloads to ensure strict isolation of data streams.
Whether for latency-sensitive applications or high-throughput workloads, multi-port SSD provides the flexibility needed to reduce the time it takes to gain insight.
In addition, with SR-IOV technology, 4150AT SSD can support up to dozens of virtual machines, which is critical given that today’s heavily loaded SoC increasingly uses virtualization to perform multitasking.
It is worth noting that each virtual machine can have its own separate storage area or namespace for storing and accessing data, and can also share datapools with other virtual machines.
This system architecture selectively allocates ports to ensure that critical data remains isolated while sharing data efficiently if necessary.
Proprietary namespaces are combined with SR-IOV to ensure that only virtual machines or hosts connected to that namespace can access data, thus ensuring the privacy and security of critical data.
This approach enables accurate storage management, whether in the cloud, edge computing, or data centers.
When designing 4150AT SSD, Micron always puts security first, equipped with the latest device-level protection and security features, including hardware-level data encryption, device authentication, secure startup and encryption signature firmware.
To improve the architectural efficiency of modern automobiles, how can what we do help to achieve a centralized architecture? “because current storage solutions typically can only connect to a single SoC, they can only be stored for specific domains or functions, such as IVI, ADAS, or attached systems.
” This limitation sometimes causes the design team to spend a lot of time and effort and make the necessary compromises to adapt the code to existing storage space and avoid double expansion (for example, from 512 GB to 1 TB).
However, sometimes there is unused or idle capacity in the storage device of a feature, such as IVI, that could have been used by other SoC for ADAS or connection.
The Micron 4150AT SSD replaces up to four storage devices, significantly improving efficiency while streamlining the architecture, thereby reducing total cost of ownership and storage costs per GB.
Another way to achieve shared storage across SoC is to connect the SSD to multiple SoC by relying on expensive car-grade PCle switches.
This method usually consumes high power and takes up valuable circuit board space.
4150AT SSD’s multi-port feature eliminates the need for switches, providing automakers with greater design flexibility while helping to reduce operating temperature and power consumption.
4150AT SSD can connect multiple SoC, reducing redundant copies of data, resulting in significant cost savings.
For example,The navigation data of a city can be as high as 100GB, which is usually shared by ADAS and IVI systems.
Current car storage solutions need to save at least two copies of such data while binding local storage to all SoC.
If it is the navigation of multiple cities, it will generate hundreds of GB of unnecessary data, resulting in economic and space / capacity waste.
The launch of 4150AT SSD will completely change that.
Starting from bit by bit to protect the earth, at present, the breakthrough advantage brought by Meguiar’s latest automotive SSD has been obvious.
What is even more exciting is that the shift to a centralized architecture will benefit us at the macro level.
According to Vicor Power, the zoning architecture reduces weight by simplifying wiring, increasing the range of electric vehicles by 4000 miles (about 6437 kilometers) a year and losing up to 40 pounds (18 kilograms) of weight compared to traditional structures.
For fuel-fueled cars, zoning structures can improve fuel efficiency (and thus save on fuel costs) and help significantly reduce carbon emissions in an environment where global warming is accelerating.
In the face of severe climate change, any bit of energy savings are crucial, and we expect the car ecosystem to be equipped with Meguiar 4150AT SSD to create lighter, simpler and more environmentally friendly cars.
For the automobile of the new era facing the future, new problems need new solutions.
To this end, Meguiar redesigned automotive storage and launched the world’s first four-port 4150AT SSD.
Its multi-port and SR-IOV virtualization technology brings unprecedented flexibility and power to the automotive ecosystem to easily cope with increasingly complex automotive data workloads.
With the accelerated popularization of generative AI and fully autonomous driving technology in the future, the scale and complexity of automobile data workload are increasing.
4150AT SSD supports a centralized architecture, bringing scalable and sustainable new choices to the automotive ecosystem, helping the industry embrace disruptive technologies and create greener cars of the future.
For automakers, the Meguiar 4150AT SSD has a small size and powerful performance, which can help the automotive ecosystem to rethink and design the cars of the future, creating unlimited possibilities.
The exciting journey has only just begun, and as people say, it is the process, not the end, that matters.
