KIOXIA's Software-Enabled Flash™ (SEF) Technology

Hyperscalers are looking to evolve and redefine the use of flash in their data centers. What is needed to accelerate this trend are tools that leverage the native speed and flexibility of flash, coupled with the ease of software-defined storage.

KIOXIAS's Software-Enabled Flash™ (SEF) technology supports this emerging paradigm by fundamentally redefining the relationship between the host and solid-state storage. SEF technology consists of purpose-built, media-centric flash hardware focused on hyperscaler requirements, with an open source API and libraries to provide the functionality hyperscalers demand.

Overhead from Traditional Industry Solutions

Firmware induced ‘long tail latency’
DRAM buffers
Device-level RAID
Overprovisioning limiting capacity
Device-level power protection

Challenges of Current HDD Driven Approach

Legacy of HDD paradigms for storage
Fixed functionality by the standards
IO blender approach to block and wear leveling creates tenant workload conflicts
Limits flash to fit the standards used

KIOXIA's SEF Technology Solutions

Enables host to control latency optimizations
Offers DRAM, no-DRAM and hybrid solutions
RAID becomes a host control decision
Gives access to full capacity of each flash die
Power loss protection option
API delivers needed tools to adapt flash at the speed developers require
Sheds the legacy HDD paradigm
Adapt single IO or multiple IO modes
Die-level workload isolation that also enables multiple IO modes to run simultaneously
Maximizes flash flexibility, scalability, performance, parallelism and speed

Simply put: SEF technology brings software flexibility and scalability to flash.
