What it hides: your NVMe drives arrive in Linux as SCSI disks on mpt3sas, queue depth 128, sharing one tag pool and one x8 uplink. Two Gen4 drives saturate the card, one Gen5 is already past it. Whether the trade still makes sense in 2026. PCIe Resizable BAR and Modern GPUs — Intel Arc, NVIDIA and AMD https://blogs.damiendye.uk/en/proxmox/pcie-resizable-bar/ Fri, 07 Aug 2026 11:00:00 +0100 https://blogs.damiendye.uk/en/proxmox/pcie-resizable-bar/ Resizable BAR lets the CPU map a GPU's whole framebuffer instead of peering at it through a 256MB window. Intel calls it required for Arc, NVIDIA enables it per game, AMD sells it as Smart Access Memory — and for AI work it changes the transfer, not the maths.
