Review Implementing and configuring modern SANs with NVMe-oF, high parallelism I/O submission and completion queue pairs ( io-queue-count ) are aligned to host CPU cores. If the customer is having a large NVMe/TCP or NVMe/FC configuration, which breaches the NVMe/TCP or NVMe/FC limits published in HWU, then it will result into over provisioning of NVMe object.
