EDSFF - A New SSD Form Factor for Next Gen Servers and Storage
The Future of Enterprise and Data Center Storage is EDSFF
EDSFF stands for Enterprise and Data Center Standard Form Factor. The EDSFF specification was created by a group of industry leaders to address the concerns of data center storage. Today, the dominant form factors are 3.5”, 2.5” and M.2 for storage applications. EDSFF aims to address the issues and limitations enterprise and data center users face with legacy form factors by designing a new specification meant for NAND flash memory. The benefits include, but aren’t limited to, better signal integrity and the ability to deliver more power to an SSD for superior performance.

EDSFF Architecture Requirements
Taking into account ‘what’s needed’ for a new form factor architecture given 2.5-inch and M.2 drive limitations, the resulting architecture needs to be a balance of these requirements to achieve an optimal design:
