I don't see anything in the Manual or BIOS screens about bifurcation support. Does anyone know if any or all 7 PCIE slots can be broken out as x4/x4/x4/x4?
The Broadcom PEX88000 PCIE 4 and Broadcom PEX9700 PCIE 3 family of chips have some very intriguing features, most interestingly Tunneled Windows Connection (TWC) that allows true multi-host to host communication via DMA. The previous generation PEX8700 only supported Non-Transparent Bridge...
The AMD v1000 series seems like the perfect system for a small form factor 1xM.2 2800 NVME + 1xSATA SSD/HDD Ceph OSD system. Connecting to an Infiniband backbone is paramount so a PCIE 3.0 x8 slot for QDR is a must have. Up to this point the best I've seen is PCIE 2.0 x8 outside of EPYC which...
I've stumbled across IEI's SPXE-11S :: IEI which has 6 PCIe Gen3 ports attached to a PEX 8724. Even though this is a backplane part, I'm wondering if this could also be used standalone as a poor man's 6-port PCIe switch.
Does anyone know if there would need to be firmware changes to be able to...
I have been running Mellanox QDR Infiniband primarily due to the magnitude of difference in latency using RDMA and its use via SRIOV in containers and VMs. Unfortunately Infiniband in the industry is almost entirely proprietary and PCIE fabrics have been a promising future for years now without...
I have 3 Threadripper servers with MCX354A-QCBT ConnectX-3 cards connected to a Voltaire 4036 via WLGORE QSFP+ cables. I would like to do an ethernet bridge with docker swarm/kubernetes, but am seeing aweful EIPOIB performance for some strange reason. Regular IPOIB gets around 12-16Gbps...
