FMS 2019: EDSFF Form Factors Update – Long, Short, & Everything In-Between
The 3″ EDSFF form factors (two lengths and two thicknesses) are the most similar to the existing 2.5″ drive form factor, and can be accommodated without overhauling a server’s layout. These 3″ form factors also seem to be attracting the least interest, and if they see widespread use it will primarily be in more traditional enterprise 2U or 3U server applications where they can take the place of U.2 drives and also replace some uses for PCIe add-in cards. The SFF-TA-1008 spec for the 3″ form factors is still sitting at version 1.0, published in March 2018. The most interesting EDSFF 3″ device we ran across at FMS this year was a Gen-Z DDR4 memory module.
