At the OCP Regional Summit 2023 in Prague, we saw an OCP DC-SCM 1.0 module at the show and thought it was worth a moment to show. For those who are not aware, the OCP DC-SCM project is designed to put server management features onto a card format so that motherboards are not BMC-specific.
OCP DC-SCM 1.0 Shown at OCP Regional Summit 2023
Here is the OCP DC-SCM 1.0 module at the IEIT booth. One can see the familiar ASPEED AST2600 baseboard management controller or BMC. There is also an Intel-Altera Max 10 FPGA, BIOS for the BMC and the system, and more. On the I/O side we get our USB, VGA, and out-of-band management ports.
The DC-SCM can have features like PFR 3.0 support, a host TPM SPI 2.0, storage for the BMC logs, and dual BIOS flash storage for the system and BMC. Here is the card installed in a Genoa server between the two risers and OCP NIC 3.0 slots.
This is going to be a technology we see in more servers over the next few generations.
Perhaps the biggest impact of the OCP DC-SCM is that it allows for server management features to be customized separately from the main motherboard. OCP has a DC-MHS project that we have mentioned a few times that moves much of the I/O off of the motherboard, and one component of that is the DC-SCM. To make this a bit easier to understand, companies like Dell and HPE that use proprietary BMCs as vendor lock-in tools can adopt DC-SCM and then offer more industry-standard OpenBMC or MegaRAC firmware on an ASPEED BMC and not have to change the rest of their server design. We will be covering more on DC-SCM in the future but thought it would be worth showing off a card for now.
