Dell EMC PowerEdge C6420 - Internal Storage; M.2 Boot Storage

Tape drive
The PowerEdge C6420 does not support an internal tape drive. External storage peripherals are not directly validated with
PowerEdge C6420, but customers can use any supported network-based storage options validated with our network and fabric card
matrix.
Internal storage
M.2 boot storage
PowerEdge C6420 introduces support for internal boot storage using the M.2 boot device. Following two options are available for M.
2 boot devices:
• Single M.2 Boot Drive connected using SATA : A single M.2 boot drive can be congured for each C6420 node. The boot
device uses a PCIe riser which uses the x16 PCIe buried riser. Note that the M.2 boot device is not a PCIe device, but a SATA
device and connects to the SATA port. The SATA port comes from the PCH chipset. This SATA connected M.2 device can work
with a single or dual CPU congurations. M.2 capacities available: 240GB
• Modular BOSS-S1: Dual M.2 Boot Drives with HW RAID connected using PCIe : Dual M.2 boot drives in RAID 1 can be
congured for each C6420 node. The boot device uses a PCIe riser which uses the x16 PCIe buried riser. A hardware RAID
controller on the M.2 card congures the two drives in RAID 1. M.2 capacities available: 2x240GB and 2x480GB
Since the M.2 RAID card utilizes PCIe connectivity from CPU2, the M.2 RAID card is only available with dual CPU C6420
congurations. The following table compares the two M.2 boot options:
