Internal Dual SD Module
The IDSDM card provides the following major functions:

Dual SD interface is maintained in a mirrored configuration (primary and secondary SD)

Provides full RAID1 functionality

Dual SD cards are not required; the module can operate with only one card but will provide no
redundancy

Enables support for Secure Digital eXtended Capacity (SDXC) cards

USB interface to host system

I2C interface to host system and onboard EEPROM for out-of-band status reporting

Onboard LEDs show status of each SD card

A BIOS Setup Redundancy setting supports Mirror Mode or Disabled

Table 17. IDSDM new features
Description
When RAID is enabled, writes to IDSDM will perform write operation to both
SD cards simultaneously
Ensures data integrity during power loss conditions
If USB 3.0 is disabled, or an error on USB 3.0 is detected, IDSDM will revert to
USB 2.0
User-defined primary SD slot for IDSDM; if RAID is enabled, content of primary
SD card will be mirrored on secondary SD card
Prevents a single bad sector from causing an SD card to fail
IDSDM does not require the BIOS to halt during POST and wait for the rebuild
to complete; rebuild happens in the background and is much faster as
compare than the previous generation
Functionality of primary SD card is not compromised if the secondary SD card
has a different speed or lower storage
Mismatch check will only happen if the IDSDM is operating in RAID mode
Only secondary SD card will be placed in mismatch state; if the secondary
card does not match the speed or have lower storage capacity than the
primary card, the secondary card will be placed in the Mismatch state
Write-protected SD cards are treated as read-only; if at least one card is write-
protected and RAID is enabled, IDSDM will operate in the degraded RAID state,
and RAID will automatically be disabled if both cards are write-protected
IDSDM will bring secondary SD card online and will make it primary if for some
reason primary SD card fails
