Updating Software
You can update controller software by loading a software package file obtained
from the enclosure vendor. A software package file contains the following software
components:

■ Memory controller FPGA
■ Management Controller and its loader
■ Expander Controller
■ Power supply unit (PSU)
■ CPLD
SMU automatically updates only those types of software that require updating.
