SAS Architecture vs
NVMe Architecture
In SAS architecture, all CPU-cores have to go through a single SAS HBA
for storage access, which creates a central bottleneck for all I/O.
With NVMe architecture, there is no central bottleneck for I/O. Every
CPU-core can talk to every device.
Refer to
Figure 4 for an example of current SAS architecture compared
to NVMe architecture.
