The document discusses EDSCRE, a new standard form factor for data centers and storage that provides increased capacities and operational efficiencies. It also discusses findings around a Gen4x4 PCIe NVMe platform that can support up to 10 media placements and saturate the Gen4x4 link. The document then covers benefits of key-value SSDs and how host application awareness and namespace types can improve system benefits. It concludes by discussing the need for continued innovation in SSD controller architectures to provide greater isolation of logical, physical, and shared resources while balancing performance and maintaining an open block management approach.

8. EDSFF is the new standard form factor for
Data Center and Storage:
- Common connector spec and pinout of x4 /
x8/x16; PCIe Gen3 through Gen5
- Optimized increase in capacities while
providing operational efficiencies
- Reduces need for proliferation of additional
form factors

9. - Hot Pluggable, allowing improved Serviceability
- Increase Capacity Support, 4/6 -> 10/12 placements
- Flexibility for carrier cards, heat spreaders and latch
enclosures
- Better thermal optimizations
- Reduces EMI /ESD issues

10. Gen4x 4 PCIe NVMe, 8 CH Platform Findings:
- Floor Planning: Max Media placements = 10
- Max Performance: Saturate Gen4 x4 link, consistent
IOPS and good QOS
- Max Capacity supported with no performance
degradation ~ 4CEs/ lane @ 1200MT/s
- Power profiling and heat sink studies

12. Enables the partitioning of functions, data placement - the main
function of FTL -is executed from host side, while media
management functions, such as NAND Flash access and error
correction, are implemented in the SSD device
Benefits:
- Application I/O Isolation improving GC, < WAF,
- Endurance Extension
- Independent I/O scheduling, < lower latency and improved QOS
- Removal of redundant mapping
- Improved media utilization

13. KV SSDs as an extension of the existing Open Channel infrastructure
KV Store Applications that use unstructured data (RocksDB /
mySQL/Ceph) suffer significant bottle necks when attempting to
access traditional block based device drivers in SSDs
KV SSD Benefits:
- Linear scaling of storage performance
- Inclusion of Metadata
- Improved resource utilization lowering system cost
- I/O Efficiencies, removal of bottle necks in processing path

14. Host application awareness combined with
standardization of Namespace Types
converges system benefits:
Namespace Types allows for inclusion of
Application Specific SSDs
NVMe Standard Benefits:
- Easy adoption and qualification by
maintaining abstraction and appearance of
HDDs
- No Need for Host understanding of
underlying FW control of FTL and media
management
- Well defined functionality & performance
- Robust Standards activity and eco-system
to drive commodities of scale

16. Still Need for innovation for SSD Controller architectures:
- Logical with no Physical Isolation
- Physical Isolation, Static vs Dynamic Isolation
- Media Isolation thorough NVM Sets and Endurance Groups
- Timing Isolation with Predictable Latency Mode
- Shared Controller Resource Isolation (Queues, Buffers, Accelerators,
Processor Cores) with priority settings
- Function isolation (FTL, GC, e.g)
Challenge:
- Complex HW and FW design of SSD controller
- Performance: Throughput balancing
- Open block management

17. Slicing SSD Controller Resources:
- Two physical back-ends of XOR, CPU, DRAM and NAND
Channel Resources
- In production with Open Channel environment today
optimizing data placement reducing noisy effects
- Incrementally evaluating the use of NVM sets in a
standard FW stack identifying opportunities for
architectural optimization

18. Next Generation, continue to slice SSD
architecture:
- Four physical back-ends of XOR, CPU,
DRAM and NAND Channel Resources
- Comparing the use of NVMe sets with IOD
vs ZNS
Next Generation:
Sliced into 4x 2 CH SSDs
