Internal dual SD module (optional)

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. In modular servers, you can choose either a redundant SD module mode or share one slot with the iDRAC module and
the remaining slot can be used for storage or as the OS partition.
The Internal Dual SD Module (IDSDM) card provides two SD card slots and a USB interface dedicated for the embedded hypervisor. This
card offers the following features:
• Dual card operation—maintains a mirrored configuration by using SD cards in both slots and provides redundancy.
• Single card operation—single card operation is supported, but without redundancy.
