Enterprise & Data Center SSD Form Factor

The Enterprise & Data Center SSD Form Factor (EDSFF) is a storage form factor for use in the data center that is being developed by the EDSFF Working Group. It is based on Intel's former Ruler SSD standard.[1]

First products conforming to the EDSFF standard have been launched:

  • Intel launched the Intel® SSD D5-P4326 Series in May 2019[2], a 15.36 TB SSD in the E1.L form factor
  • Supermicro launched their first E1.L (Long) & E1.S (Short) chassis[3][4]
  • Echostreams launched their 2U 108-drive chassis, with up to 3.3 PB of all-flash storage[5]

Early products conforming to the EDSFF standard have been announced:

  • Intel has announced[6] a series of SSD devices
  • Supermicro has announced an enclosure or storage server[7] for 32 EDSFF SSDs.

EDSFF SSDs are made in two sizes: E1.L (Long) and E1.S (Short). Samsung's NF1 form factor competes with EDSFF[8], and both are meant to replace M.2 and U.2 drives in data center applications.
