Key Features of the MegaRAC MG9085:
- Low-cost single chip solution
- 1 SGPIO / 1 SES-2 channel up to 6 drives
- USB Firmware Upgrade
- LQFP-32 (9mm x 9mm)
The MegaRAC® MG9085 controller helps optimize backplane layout with the latest enclosure management technologies. Highly integrated and space-optimized, the chip features an integrated internal oscillator, measures only 9 x 9 mm, and does not require the usual plethora of components that drive backplane costs upward: external crystal, flash memory, regulator, EEPROM, LED Driver, FRU, and transceivers. This may bring significant savings, depending on the design and configuration of your project. In addition, reducing the number of components on the backplane makes for simpler and cleaner designs, which improves time to market (TTM). Developers can further improve TTM by utilizing AMI’s 966 development board.
The MG9085 enclosure management controller manages LED patterns for up to six SAS/SATA drives, providing drive activity, Fail/Rebuild and Locate signals. The chip can directly drive 2 LEDs for up to 6 slots or 3 LEDs for up to 4 slots; it determines the number of drives by sensing the connections on the Mx-bus. The MG9085 supports SGPIO and SES-2 over SMBUS.
MG9085 can be utilized in a variety of designs. Various reference designs are already available from AMI.
AMI offers a variety of hardware and software tools for firmware upgrade and configuration via IPMI or USB. A convenient USB2.0 utility provides status monitoring, diagnostics and firmware upgrade independent of the system BMC controller.
