What keeps increasingly complex AI racks manageable? A broader control layer connects compute, power, cooling, and monitoring systems.
MaxLinear has introduced RackCommander, a portfolio of semiconductor products designed to provide connectivity, monitoring, control, and power-management functions for AI rack-scale infrastructure. The portfolio targets systems where multiple compute nodes, accelerators, power shelves, cooling systems, sensors, and service processors need to be managed as a coordinated unit.
As AI infrastructure moves beyond individual servers towards rack-scale architectures, management functions also need to extend across the entire rack. RackCommander is intended to provide the hardware interfaces required to access, monitor, and control these distributed resources without relying solely on the production network.
The portfolio can support console access, infrastructure communication, telemetry aggregation, rack-level monitoring, and power protection. This allows system designers to build a separate management layer that can remain available for servicing and recovery even when the main compute or production network is unavailable.
The portfolio combines several types of ICs. USB-UART devices provide console connectivity for system bring-up, maintenance, monitoring, and recovery, while an RS-485 transceiver enables communication with power, cooling, sensors, and other rack infrastructure. I²C and SPI GPIO expanders extend the number of monitoring and control signals available to the management system.
Power functions are handled through eFuses and buck regulators, which provide power protection and regulation for rack infrastructure. The portfolio includes the Coronado and Laguna USB-UARTs, Carmel high-speed USB-UART, RS-485 transceiver, multiple GPIO expanders, eFuses, and step-down regulators.
“Future AI racks must securely connect compute nodes, power shelves, cooling systems, sensors, and service processors into a unified management domain,” said Amit D. Bavisi, Ph.D., Senior Vice President and General Manager of MaxLinear’s Analog Mixed-Signal Business Unit.
