EDSFF High-Speed Connectors and Cable Solutions
Specifications and Standards
The EDSFF connectors featured under this category adhere to many different specifications and standards. As the name suggests, they adhere to EDSFF, which stands for Enterprise and Datacenter Standard Form Factor, a specification designed to optimize the performance and efficiency of solid-state drives (SSDs) in high-performance computing and data center environments. This standard addresses the growing demands for data throughput and flexibility, providing a framework for various storage solutions.
The Storage Networking Industry Association or SNIA, is a non-profit organization that focuses on developing standards and best practices to enhance interoperability among storage solutions. Within SNIA, the Small Form Factor Technology Affiliate Technical Work Group, or SFF TA TWG, plays a critical role in creating technical specifications for storage media, networks, and connectors. This group ensures that the specifications meet industry standards, facilitating the procurement of compatible products across different vendors. The different connectors under this series meet standards such as SFF TA 1002, SFF TA 1035, and SFF TA 1020.
Common Features
- High-Speed Data Transmission: EDSFF connectors support impressive data rates, from 32GT/s to 64GT/s, and can upgrade to 112GT/s PAM4 and 224GT/s PAM4 in the future. This capability is essential for environments requiring rapid data access, such as artificial intelligence (AI), machine learning (ML), and high-speed computing. The E1/E3 E1/E3 High-Speed Cable Assembly is tooled to Gen 5 EDSFF orthogonal 1C/2C/4C as per PCI-SIG CEM.
Compact and Efficient Design:
- The EDSFF 2-piece cable solution features a Mini Cool Edge 1C/2C/4C on one end; the other end allows for connector form factor selection (e.g., MCIO, Multi-Trak, backplane connectors). It has a two-piece cable solution that facilitates direct connection to the main PC board, which supports PCIe® 5.0 data rate of up to 32Gb/s.
- The Mini Cool Edge 0.60mm Card Edge Connector is designed for board-to-board applications with configuration options such as vertical, right angle, straddle mount, and orthogonal, and also supports interconnections with high-speed cable.
- The Cool Express Link™ EDSFF E3 2C PCIe® Gen 5/6 Cable Connectors feature a robust die-cast cage design that provides stability and durability while facilitating high-speed data transmission. Its hybrid configuration allows for efficient routing of power and signals through a midplane, optimizing performance in high-density computing environments.
- The PCIe® Gen 6 Mini Cool Edge 0.60mm connector is designed as a high-density, high-speed card edge connector tailored for new-generation small form factor systems rated up to 64GT/s. Its 0.60mm pitch allows for a compact footprint, making it an effective space-saving solution.
- Compliance with Standards: EDSFF connectors adhere to industry specifications such as SFF-TA-1016 and SFF-TA-1035, ensuring compatibility with a wide range of devices including SSDs, CXL modules, and backplane connectors.
