To make sure that the introduction of SVP3A doesn’t degrade the performance of common storage management tasks, we measured the performance of a set of common storage management tasks by using Storage Navigator. This blog illustrates the performance of Storage Navigator running on the new, enhanced SVP3A hardware compared to the performance running on the existing SVP3 hardware.
Test Procedure
To ensure that there was no performance degradation between SVP3 and SVP3A, we performed a common set of storage management tasks using Storage Navigator on SVP3 and SVP3A with the default configuration and with a modified configuration.
Here, default configuration means that nothing was changed on the SVP3 and SVP3A. In the modified configuration, the value of the LSO (Large Send Offload) parameter was changed (set to Disabled from Enabled) on SVP3 and SVP3A before performing any storage management task.
For this performance evaluation test, we used similar conditions across two different SVP versions. We used two different storage system models, VSP E990 and VSP F/G-350, and the storage SVOS version remained the same during the performance evaluation on SVP3 and SVP3A.
The test objective was to compare the provisioning time for SVP3 and SVP3A. Operation times include:
· Creating a parity group.
· Creating basic volumes.
· Creating, expanding, and deleting DP Pool.
· Creating and deleting DP-VOLs.
· Attaching two LUNs to four paths.
· Refreshing the storage system.
· Gathering a detailed DUMP.
Data Collection Process:
· Operation times were collected from the Storage Navigator Tasks log.
· Isolated storage unit was used when the tests were run. Identical environment pools, RAID, and resource groups were used for each test.
· All tests were repeated five times, and the average run time was calculated.

Summary
Performance evaluation tests show no significant performance degradation using SVP3A compared to SVP3. From the results, it is also evident that SVP3A performed better with a high-performance, large-capacity storage system like VSP E990 and can continue to be used across different Hitachi storage systems.
