MCIO high-speed cable is a high-performance cable based on multi-channel input/output (MCIO) interface technology, designed to meet the high-speed signal transmission requirements of next-generation data centers, servers and high-performance computing equipment. The following is a comprehensive analysis of its core features and application scenarios:
1. Technical definition and core functions
MCIO (Mini Cool Edge O) supports PCIe 5.0/6.0, CXL (Compute Express Link) and SAS4.0 protocols by merging multiple physical channels into a single high-speed data stream, and can achieve a maximum transmission rate of 128Gbps (PCIe 5.0) and 24Gbps (SAS4.0). Its design goal is to optimize signal integrity, reduce signal attenuation and crosstalk in a limited space, and improve system energy efficiency.
2. Physical characteristics and design advantages
Compact structure: With a high-density layout with a pin pitch of 0.6mm, it is suitable for internal wiring of space-constrained devices (such as servers and network switches), which significantly saves space.
High reliability: Enhanced mechanical strength and durability through innovative structural design, supports multiple plug-ins and unplugging without damage, suitable for frequent maintenance scenarios in data centers.
Compatibility: Can adapt to a variety of device interfaces, such as ICY DOCK's hard disk extraction box and Yihua's CEM-MCIO components, the latter of which integrates high-speed copper cables and structural parts to meet the high-speed signal transmission requirements between AI server GPUs.
3. Application scenarios
Data centers and servers: Used in scenarios such as GPU interconnection and storage expansion cards, supporting high-performance computing tasks such as AI training and cloud computing.
Network equipment: Realize high-bandwidth data transmission in switches and routers to meet 5G and edge computing requirements.
Storage devices: Combined with products such as hard disk extraction boxes, provide flexible storage solutions, such as connecting 3.5-inch hard disk slots through MCIO interfaces.
4. Industry dynamics and manufacturer layout
Technology iteration: MCIO interfaces are gradually replacing traditional SAS/SATA interfaces and becoming a new generation of high-speed transmission standards. For example, Yihua's CEM-MCIO components have met the PCIe 5.0 specification and plan to adapt to higher specifications in the future.
Product development: Many manufacturers have launched MCIO interface motherboards, adapter cards and cables. ICY DOCK has also developed an MCIO hard disk box that is compatible with the optical drive slot to further expand the scope of application.
5. Performance comparison and future trends
Compared with traditional interfaces (such as SlimSAS), MCIO has more advantages in bandwidth density and energy efficiency. With the popularization of PCIe 6.0, its transmission rate is expected to be further improved. At the same time, modular design will reduce system complexity and promote data centers to develop in the direction of higher performance and lower power consumption.
MCIO high-speed lines have become a key technology for high-speed interconnection between next-generation data centers and servers through high density, multi-protocol support and reliable design. In the future, it will further penetrate into cutting-edge fields such as AI and autonomous driving.
