At the OCP Regional Summit 2023 in Prague we saw a new AMD EPYC Genoa server sled from MiTAC called the Capri2 CP2S11. MiTAC, for those unfamiliar, is the parent of Tyan and is taking over Intel’s server business focusing on hyper-scale designs. One of the new designs is an OCP AMD EPYC Genoa platform.

The MiTAC Capri2 CP2S11 is a 1/3 width 2OU form factor designed to fit three nodes in 2OU of rack space. Here is the AMD Socket SP5 that we have seen a number of times. Of note, there are only eight DDR5 DIMM slots. There is a misconception that all hyper-scalers use two DIMMs per channel and full memory loads in all servers. This is an example where not even all 12 channels of DDR5 fit in the platform due to physical size constraints. We covered this a bit in our Why 2 DIMMs Per Channel Will Matter Less in Servers piece recently.
MiTAC did not have the cooler installed, but we found one in a pre-production red board version of the Capri2 on the show floor at another booth.
One of the advantages of the sleds is that the front is full of I/O. Here we have our normal management ports and an OCP NIC 3.0 port. There are four E1 EDSFF drive bays on the right side of the node and three full-height PCIe Gen5 slots on the top left.
Here we can see the riser that goes with this featuring two x16 slots and one x8 slot. The PCIe slots are cabled as well.
The rear of the unit is where the two fans and the bus bar power connector are.
Overall, it was great to see a design like this out in the wild. We hope to cover more of these designs like the Capri2 in the coming year. In the meantime, if you want to learn more about AMD EPYC 9004 “Genoa” platforms, you can see our AMD EPYC Genoa launch piece.
