I am evaluating all-flash VMware vSAN for a 3 node cluster and the performance is abysmal even with NVMe cache disks. I think I can get better performance if I have more disk groups. However, I only have one PCIe x8 slot available and in ESXi each disk can only be claimed by one disk group, so I will need a way to split a physical NVMe disk into multiple logical disks.
The build-in way to do this is with namespaces, but I only managed to find one model that supports more than one name space (Samsung PM1725a). Does anyone know any other disks that do?
Alternatively, is there any other way to split the drive or fit more than one drive into one PCIe slot?
