Scenario A: One Virtual Machine per Blade
Figure 62 shows that the system is capable of delivering up to about 1200 IOPS (random read) with a response time of less than
20 milliseconds, which aligns with the expected disk performance

For a random read and write workload, IOPS scales linearly with additional nodes with acceptable response times (less than 20
milliseconds). A six-node system can deliver up to 1113 IOPS with a response time of 10.78 milliseconds (Figure 63).
