AMI Backplane Controllers from AMI provide LED and sensor control for SAS/SATA/NVMe drives. They provide exceptional flexibility and require minimal board real estate, making them a perfect fit for numerous applications.
A wide selection of reference designs and development tools are available to help speed the design process. AMI's Backplane Enclosure chips work with any HBA supporting SGPIO (SFF-8485) and/or SES-2 protocol over I2C. These Backplane Controllers can be flashed or upgraded via SMBus from the motherboard BMC, or USB, depending on the model.
