IDSDM/vFlash card
The XC640 Series system supports Internal Dual SD module (IDSDM) and vFlash card. In the 14th generation of XC Series 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 micro SD cards for IDSDM and one card for vFlash. Micro SD cards capacity for IDSDM are 16, 32, or 64 GB, while for vFlash
the microSD card capacity is 16 GB.
NOTE: One IDSDM card slot is dedicated for redundancy.
NOTE: It is recommended to use Dell branded micro SD cards associated with the IDSDM/vFlash congured systems.
