PernixData FVP testing – part 3

fvptesting01

Configured the Flash Cluster, it’s time to verify the enhancements PernixData FVP brings to the storage running some stress tests. To test FVP VMware-IO-Analyzer 1.6, FIO 2.1.9 and Jetstress 2010 benchmark tools have been used.

Tests have been performed in my LAB environment where hardware and workload are of course different compared to a real production environment therefore results should be taken just to have an’idea of the FVP potential.

Notes

PernixData FVP is definitely an interesting solution that brings real benefits to the storage.

Having 30 days fully working trial the administrators can test the product with different scenarios getting an overview of the FVP impact to the storage I/O performance.

Results strongly depend on used hardware and workload in the network and real benefits can be analyzed comparing parameters before and after FVP activation.
