Aries SCM Highlights
Enabling Reliable PCIe/CXL for Rack-to-Rack Connectivity
Why Use Aries Smart Cable Modules?
Aries SCMs enable robust, easy-to-design PCIe and CXL cabling while also offering COSMOS' suite of built-in advanced fleet management, security, and deep diagnostic capabilities critical to ensuring high reliability and up-time.
Robustness
Supported Data Rates: 32 GT/s, 16 GT/s, 8 GT/s, 5 GT/s, and 2.5 GT/s Data Rates with Automatic Link Equalization
Power Efficient: Low power CMOS process and L1.0 Low-Power Mode minimizes rack power/thermal density
Low Latency: Less than 10ns
Security: Advanced security features help prevent malicious attacks of unauthorized firmware loading, module diagnostics access, and configurations
Easy System Design
Thin Cable Gauge: Offering thin cables in various lengths for flexible bend radius
Extended Reach: Up to 7m for long reach inter-rack connectivity
Flexible Supply Chain: Aries SCMs are compatible with multiple cable vendors for ease of second sourcing of active cable assemblies
Interop Testing: Rigorous system testing with 50+ Endpoints and all major Root Complex
Fleet Management
Quick Debug: Built-in protocol analyzer with Link state history and timestamps, full non-destructive eye scan for RX Lane margining, self-test features to minimize link downtime and accelerate fault isolation
Deep Diagnostics: Firmware-driven link health monitoring to alert BMC of any possible link performance issues
