Flash storage is the “go to” option in the modern data center to overcome storage I/O bottlenecks. The problem has been how to get full performance for the flash investment. The zero latent nature of flash exposes bottlenecks throughout the I/O chain. In this slideshare we discuss how the various storage interconnects (SAS/SATA HBA’s and PCIe bus) have incurred a latency penalty. These interconnects have kept flash storage from reaching its full potential. The memory bus is the final frontier in flash performance.
In this slideshare you will learn:
- How latency is introduced by each flash interconnect
- What the performance ramifications are of this latency
- How to reach the full performance potential of flash-based storage by leveraging the memory bus
- How memory bus based flash changes the game for how flash can be used in the data center
