The Backplane Controller series 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, along with development boards to speed integration in specific OEM designs. 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.
