EVOLUTION OF MEMORY DEVICES FOR EDGE COMPUTING

Presenter: Dr. Sungwook (Sung) Ryu, Samsung

Computer system architecture has been changing due to new application
requirements and evolution of hardware. Mainframe computer used to be a prevail
solution but distributed workstations, cloud, and edge computing have been
adapted. I will go over what have been driving the architecture changes and talk
about the detailed requirements of edge computing. Samsung is developing memory
devices for edge computing, which include Computational Storage, ZNS (Zoned
Namespace) SSD, PIM (Processing In Memory), and MRAM. I will discuss how these
devices can address the issues on edge computing for power, latency and form
factor.

INNOVATION WITH SMARTSSD FOR GREEN COMPUTING

Yang Seok Ki, Vice President and CTO

Carbon neutrality is becoming an important issue in the industry. Data centers
are currently known to consume 1-2% of global electricity usage. Data centers
are transforming their architecture to improve total cost of ownership (TCO).
But now environmental impact is also becoming an important factor. Therefore, it
can be said that green computing, which increases computational efficiency with
low energy consumption, has great significance. I note that this is also a
problem stemming from the traditional CPU-centric general-purpose computing
model. Therefore, accelerators based on different domain-specific architectures
are becoming important not only from a basic TCO point of view, but also from a
green computing point of view and can be a potential solution. In particular,
Samsung has been approaching these issues from the perspective of memory and
storage, and has emphasized the importance of a data-centric computing as an
alternative to the existing compute-centric computing.
 
This keynote will showcase the innovations Samsung is making in storage devices
through the SmartSSD concept and share its long-term vision to enable
power-efficient green computing through data-centric computing. We would also
like to invite the industry to collaborate on realizing data-centric computing
across various accelerators for more power-efficient data processing.

WHY SHOULD THE STORAGE COMMUNITY CARE ABOUT CXL?

Presenter : Yangseok Ki

The exponential growth in data volume and traffic across the global internet
infrastructure is motivating the exploration of new architectures for data
centers to achieve the demand for better performance, efficiency and total cost
of ownership (TCO). One promising trend is to segregate the functional
components of compute, memory, storage, and networking into pools and organize
them as needed according to the specific needs of different workloads. This
disaggregation and composability will take us beyond the classic architecture of
servers as the unit of computing.

Backed by a broad consortium of hyperscalers, equipment OEMs, chipmakers and IP
vendors, Compute Express Link (CXL) is a new enabling technology for
interconnecting computing resources that embraces existing competing
technologies such as Gen-Z and OpenCAPI. Currently in Gen 3.0, CXL enables
high-speed, low-latency links with memory cache coherency between processors,
accelerators, NICs, memory, and storage.

In this keynote, Dr. Ki would like to share the opportunities and challenges
that exist across hardware and software, with a focus on Samsung’s CXL memory
technologies such as CXL memory expanders and memory semantic SSDs. In
particular, he will share the direction Samsung wants to move forward with the
storage community and suggest various collaboration opportunities.

OPEN SOURCE CONTRIBUTIONS


Multi-stream
Multi-stream is a technology that allows SSDs to receive host hints(e.g., stream
IDs) for data lifetime and place a similar lifetime data(e.g., same stream ID)
to a set of erase blocks. This way SSDs are able to minimize garbage collection
overhead since the lifetime of data in one erase block would be similar and
whole data in one erase block would be valid or invalid during garbage
collection time. The multi-stream is already standardized in NVMe and T10 (SCSI)
standards groups. The multi-stream open source software package includes patches
of fio benchmark tool, nvme cli tool, sg3 utilities, Linux Kernel and Qemu to
support the multi-stream. It also includes examples that contain example C
programming codes demonstrating how Stream Directive is used in application
writes.

KV SSD
KV SSD open source software package includes the host software that operates
with KV SSD. The package includes API library, emulator, kernel device driver
and performance evaluation suite called kvbench. With the package users can
evaluate multiple application(e.g., RocksDB, Aerospike, etc.) performance on
block device in addition to direct key-value stack performance on KV SSD.

KVCeph
KVCeph provides a new CEPH object store called KvsStore. It is integrated with
Samsung Key-Value SSDs, offloading the object management layer from CEPH to a
device. KvsStore reducing IO and compute overheads per device in a host system,
and thus improving performance and scalability; more number of SSDs can be used
in a single host system without performance degradation. This project also
demonstrates the use of Samsung Key-Value SSDs in implementing complex storage
operations such as transactions, and object filtering and listing.

1U Mission Peak
The 1U Mission Peak server platform was contributed to OCP, and it was developed
with the latest technologies with up to 576TB of high-speed NF1 (NGSFF) form
factor NVMe SSDs. It offers more than 5X higher capacity and 3X more IOPS than
traditional flash storage solutions within the same footprint and ease of
implementing this total solution in data centers.

DSS
Disaggregate Storage Solution (DSS) provides high throughput and highly scalable
storage solution for AI and Analytics workload. AI/ML is not new, but
innovations in ML models development have made it possible to process data at
unprecedented speeds. Data scientists have used standard POSIX file systems for
years, but as the scale and need for performance have grown, many faces new
storage challenges. Samsung has been working with customers on new ways of
approaching storage issues with object storage designed for use with AI/ML. We
welcome you to join the DSS community and explore how software and hardware are
evolving to allow unprecedented performance and scale of storage for Machine

Disaggregated/Rackscale/Composable Architecture

Everything in the data center is software defined, and new technologies like
NVMeOF, CXL and fiber optics are making the systems in the data center
disaggregated. SW and HW architectures for composable and disaggregate
rack-scale architectures are emerging. How should storage and memory subsystems
evolve over time to meet these requirements, and which architecture is right for
new trends?

System Security

This is a broad topic that includes system security (e.g., various cyberattacks
against servers in device and the device with computing capabilities), data
security (e.g. homomorphic encryption), and programmatic security (e.g. compiler
techniques that check for program vulnerabilities).
