4.2 Base configurations
Figure 11 shows the measured sequential read and write performance of the Small, Medium and Large
configurations (base configurations) of the Dell EMC Ready Solution for HPC BeeGFS High Capacity
Storage.
Measured IOzone sequential performance of base configurations
The small configuration using a single ME4084 array shows a peak read performance of 6.84 GB/s and peak
write performance of 5.74 GB/s. We observe a linear increase in performance as we add ME4084 arrays from
Small to Medium to Large configurations.
