Storage Controller
Dell EMC’s RAID controller options offer performance improvements, including the MiniPERC solution. Mini PERC provides a base
RAID HW controller without consuming a PCIe slot by using a small form factor and high density connector to the base planar.
The new PERC controller offerings leverage heavily on previous generation PERC family. The premium performance PERC series
controller drives better IOPs and enhanced the SSD performance.

IDSDM with vFlash card
The Internal Dual microSD Module (IDSDM) and vFlash card are combined into a single card module in the latest PowerEdge
systems. The following are SKUs available for PowerEdge R940xa systems:
•
vFlash only
•
IDSDM only
•
vFlash and IDSDM
NOTE: The IDSDM only option come with vFlash hardware but required iDRAC Enterprise license to enable it.
The IDSDM with vFlash module sits in the back of the chassis, in a Dell-proprietary PCIe x1 slot using a USB 3.0 interface to host. In
14 Gen system, the IDSDM and/or vFlash card moves from SD to microSD and the supported capacity for IDSDM microSD cards are
16, 32, and 64 GB while for vFlash the capacity is 16 GB only. The write-protect switch is built onboard on the IDSDM with vFlash
module.
