I have no idea, still processing the ISOs and not really into server stuff myself. ps, can you please edit the quote and remove the majority of my post? just leave the first line in the quote, or simply use @Enthousiast, it will ping me too.
Only Server 2025. But the difference is not huge - after all the NVMe controller itself was always natively supported, they just replaced Disk.sys in the stack for NVMe disks with a newer/better version. Maybe if you have PCIe 5 SSDs - I don't. IMHO it's nowhere near the latency difference between iSCSI and NVMeOf + RDMA. Hopefully this will fix the native NVMeOf MPIO support/performance they promised at launch.
