IDSDM/vFlash card
This module contains the Internal Dual SD Module (IDSDM) and vFlash card that are combined into a single card module. There are
two SKUs available:
•
vFlash
•
IDSDM
The IDSDM with vFlash module has a dedicated slot at the back of the system chassis. This is a Dell-proprietary PCIe x1 slot that
uses a USB 3.0 interface to host. In the system, the IDSDM and vFlash card size changes from SD to microSD and the supported
capacity for IDSDM microSD cards are 16GB, 32GB, or 64GB, while the vFlash capacity is 16GB only. The write-protect switch is
built onboard the IDSDM/vFlash module.
Boot Optimized Storage Subsystem (BOSS)
BOSS is
offered
as a means of booting 14G servers to a full OS in the following scenarios:
•
A solution such as IDSDM may be desired, but the target OS is a full OS (not just hypervisor).
•
The user does not wish to trade
off
the standard hot-plug hard drive slot for OS install.
•
A separate hardware RAID is required for OS boot so that data drives can be in Passthrough mode with a HBA.
BOSS is a PCIe card located at the rear of the system to support up to two 80mm or 110mm M.2 SATA or PCIe x1 devices.
NOTE: BOSS drives are not hot-plug capable.
