Single and Dual Ported NVMe SSD Universal Backplane Management Controller

The MG9100 UBM Controller is a low-cost, small footprint solution for enclosure management of single and dual ported NVMe SSD Backplanes as well as traditional SAS/SATA backplanes through UBM (Universal Backplane Management) protocol, which is achieved with the help of two UBM SMBuses to communicate with the UBM controller on the host. A single MG9100 controller supports up to 8 drives, maximum of 32 drives are supported when four MG9100 controllers are cascaded together.

Legacy protocols such as SGPIO (SFF-8485), BMC & VPP/SHP are also supported in MG9100. MG9100 can also manage backplanes with combination of SAS/SATA & NVMe SSDs. Host Hot-Plug VPP or SHP SMBuses are used for LED management of NVMe drives, and SGPIO for SAS/SATA drives. Optionally, LED management can also be achieved with BMC SMBus.
