IDSDM
The Internal Dual SD module (IDSDM) provides you with a redundant SD card solution. You can configure the IDSDM for storage
or as the OS boot partition. The IDSDM card offers the following features:
● Dual card operation — maintains a mirrored configuration by using SD cards in both the slots and provides redundancy.
NOTE: When the Redundancy option is set to Mirror Mode in the Integrated Devices screen of System Setup, the
information is replicated from one SD card to another.
● Single card operation — single card operation is supported, but without redundancy.
