Supermicro blows AMD out of the water when it comes to density. Here's equivalent 4 node in 2U AMD systems (they differ based on disk configuration -- SAS, NVME, or a mix of both). They also support Supermicro SIOM, so you can choose what integrated networking you want: http://www.supermicro.com/Aplus/system/2U/2123/AS-2123BT-HNC0R.cfm http://www.supermicro.com/Aplus/system/2U/2123/AS-2123BT-HNC... http://www.supermicro.com/Aplus/system/2U/2123/AS-2123BT-HNR.cfm http://www.supermicro.com/Aplus/system/2U/2123/AS-2123BT-HNR... http://www.supermicro.com/Aplus/system/2U/2123/AS-2123BT-HTR.cfm http://www.supermicro.com/Aplus/system/2U/2123/AS-2123BT-HTR... If you wanted even more density, there's the MicroCloud and MicroBlade series (although they use Intel processors): https://www.supermicro.com/products/MicroBlade/ https://www.supermicro.com/products/MicroBlade/ https://www.supermicro.com/products/nfo/MicroCloud.cfm https://www.supermicro.com/products/nfo/MicroCloud.cfm That being said, these don't make a lot of sense unless you're very space-constrained, or your racks have a ton of power available. Given a 30A 208V circuit, I could only safely run three of the above AMD systems at full power. I'd rather just get dedicated 1U or 2U servers, and not have to make compromises about expandability or serviceability.
