IDSDM or vFlash card
The PowerEdge R640 system supports Internal Dual SD module (IDSDM) and vFlash card. In the 14th generation of PowerEdge servers,
IDSDM and vFlash card are combined into a single module, and are available in the following options:
•
vFlash or
•
vFlash and IDSDM
The IDSDM/vFlash card can be connected in a Dell-proprietary PCIe x1 slot using a USB 3.0 interface to host. IDSDM/vFlash module
supports two MicroSD cards for IDSDM and one card for vFlash. The MicroSD card capacity for IDSDM are 16, 32, or 64 GB, while for
vFlash the MicroSD card capacity is 16 GB. The IDSDM or vFlash module combines the IDSDM or vFlash features into a single module.
NOTE:
There are two dip switches on the IDSDM/vFlash card for write-protection.
NOTE:
One IDSDM card slot is dedicated for redundancy.
NOTE:
It is recommended to use Dell branded MicroSD cards associated with the IDSDM/vFlash configured systems.
