Solid State Storage Initiative

 

Welcome to the Solid State Storage Initiative (SSSI), dedicated to fostering the acceptance and growth of Solid State Storage (SSS) in the marketplace.  To achieve those goals, SSSI provides education, performs market outreach, and influences / promotes standards.  Work is ongoing within SSSI in several areas.

 

Performance

 

SSSI is leading the way in understanding and quantifying SSS device and system performance.SSDs behave very differently than HDDs, and standard HDD benchmarks will not provide a true picture of SSD performance. 

The SSS Performance Test Specifications were developed by the SNIA SSS Technical Work Group (TWG) and define how to measure SSD performance in a manner that is accurate, repeatable and enables comparison between different manufacturers’ products. 

The SSS System TWG, building on the work of the SSS TWG, is developing a specification for measuring the performance of SSS systems.

 

NVDIMM

 

A Non-Volatile Dual In-line Memory Module (NVDIMM) operates from DRAM with Flash as backup to create a high performance non-volatile storage device that plugs directly into the memory bus.  The SSSI NVDIMM Special Interest Group is shepherding this technology into the marketplace.

 

NVM Programming Model

Non-Volatile Memory (NVM) features and performance are outgrowing the existing storage model.  NVM is evolving to be less like storage, more like memory.  The SNIA NVM Programming Model, developed by the NVM Programming TWG, defines new software programming models for NVM.   The model describes extensions allowing software to utilize NVM features and enables designers to develop APIs that take advantage of NVM features and performance. 

 

PCIe SSD

 

PCI Express (PCIe), the ubiquitous system bus, has evolved to become a storage device interface.  SSDs are able to take advantage of the high bandwidth of PCIe and are available in multiple form-factors.  The SSSI PCIe SSD committee provides guidance to the marketplace on PCIe SSDs. They also coordinate with other industry organizations involved in PCIe SSD activities to access additional expertise and to provide a broader industry perspective for our members.
