5.6 NVME CPU usage example The advantage of FC-NVMe attached is shown in Table 5-1. This table compares the CPU  load on a Linux system with three different FlashSystem 900 attachments: This examples gives an idea of the CPU load depending on the used attachment. It is an  example only depending on the given workload and does not represent any values to be  achieved in a client’s environment.
