## 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: 

GLYPH<SM590000> FC-NVMe, native multipathing 

GLYPH<SM590000> FC-NVMe, using the operating system multipathing 

GLYPH<SM590000> FC-SCSI, using the operating system multipathing and the iSCSI protocol over FC 

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.
