Aries SCMs are an offering within Astera Labs’ COSMOS suite enables system baseboard/system management controllers (BMCs/SMCs) to utilize an array of customizable diagnostics and telemetry features to enable continuous monitoring of critical server-to-JBOG, JBOG-to-JBOG, and Switch-to-JBOG links. Parameters such as eye opening, equalization levels, junction temperature, and more are monitored, and interrupts to the host can be enabled whenever configurable limits are crossed. A full set of self-test features—host-side and line-side loopback, pseudo-random bit sequence (PRBS) generation and checking, etc.—enable rapid troubleshooting to minimize link down time and accelerate fault isolation.
