EDSFF is mainly divided into two types, length and length.EDSFF 1U LongAbbreviationE1.LVery similarIntelThe original Ruler is ideal for high-density storage with thicknesses of 18 mm and 9.5 mm.
SK Hynix's PE8111 uses this design, with PCIe 3.0 x4 and its own 3D V6 TLC flash memory, with a capacity of 15.36TB and 30.72TB.
Microsoft Azure Olympus FX-16 1U JBOF is equipped with E1.LSSDThe single block capacity is 16TB, and the total of 16 blocks is 256TB.
There is also a short oneEDSFF 1U ShortAbbreviationE1.SOriginally designed for the purposeReplacing M.2 in the data center to solve its various shortcomings, the horizontal and fast can accommodate two rows of flash memory particles, support hot swap, 12V power supply to support higher power supply, heat dissipation is also easier.
E1.S originally only defined the PCB board size, the power consumption did not exceed 12W, and the others left it free to play. The result could not be saved, and it soon appeared.20W power versionWith a thick outer casing and heat sink, it seems to be shortened E1.L.
Afterwards25W, thickness added to 25mmNo matter the power consumption or performance, it basically reaches the grade of 2.5 inch U.2, but the heat dissipation is more convenient.
The use of E1.S is not limited to SSDs.Various accelerators are beginning to appearFor example, BittWare brings an FPGA.
There is also a derivative 3-inch size that is nearly 2.5 inches in size, and SMART Modular showcases the world's first sub-standard DDR4 Gen-Z module.
