How is NVMe technology scalable?
NVMe SpecificationThe NVMe protocol was designed to be scalable through asynchronous IO and not having to be blocked by uncacheable register reads. NVMe architecture is scalable across multiple interfaces, through PCIe with NVMe technologies and networked fabrics through NVMe-oF architecture. It can scale performance with varying PCIe lanes and higher capacity SSDs, it can scale from mobile devices to data centers.
