Test Results
The simulations were designed to be highly reproducible, meaning that we could reproduce test results
if identical circumstances were provided. In each configuration we held everything else constant
except the number of EqualLogic PS6000XV arrays. We used the various application throughputs from a
single PS6000XV array configuration as the baseline. The test results from the other two configurations
were then compared to the baseline to determine the performance of each configuration relative to
the baseline. This comparison allowed us to show the performance improvements in each configuration
as we added additional PS6000XV arrays to the storage pool.
Figure 5 shows the simulation test results for three hardware configurations where the CPU, memory,
and network subsystems were kept constant and only the storage capacity in the EqualLogic FS7500
was increased by adding additional PS6000XV arrays. The height of each bar in this chart shows the
normalized application throughput in a VMware environment via NFS. These test results clearly show
that in a VMware environment, with multiple virtual applications running on an EqualLogic unified
scale-out NAS, a near linear increase in application transactional performance is achieved when
additional storage capacity is added. We were easily able to provision additional capacity in the
EqualLogic FS7500. Each time the PS series array was automatically discovered and added to the
storage pool, and data was load-balanced across all the disks in the pool while the applications were
running. As we increased the workloads, the application performance increased at a near-linear rate
with capacity.
