  8. 8. 8confidential 8 LSI Nytro Architecture Pros:  Tradition architecture and zero cost for maintain  Online FW/DR upgrade without shutdown the system  No DRAM as buffer, no additional thermal and power safety method. Cons:  No DRAM as buffer, the random read need twice ops  In the low queue deep application, can’ utilize the whole performance  The absolute latency big than other architecture.

  10. 10. 10confidential 10 MySQL 5.6+
  11. 11. 11confidential 11 Application trend  As more and more flash in market, the application want to change from low QD to deep QD to utilize the low layer hardware performance  The parallelization will help application increase the workload.  The hybrid solution like HD+Flash will shrink as too complex
  12. 12. 12confidential 12 LSI in Future  New Sandforce controller will release in Q3/14.  Already have the product line to add DRAM to meet low latency application.  Move from SATA interface to NVME  Add DRAM in the some Sandforce product line  NVME based solution include the RAID function.
