@Sergey thanks for sharing this information! so to be clear the only difference between getting 1,2Gbps and 9Gbps is the operating systems that is installed. is the test based on VMs running on top of VMware ESXi? 

@Mike Struening can you elaborate on my previous question? reading back you post one more time really makes me curious who development is making sure the performance is kept in line with expectations also during OS certifications and in addition if a newer OS version come with increased performance enhancements which benefits Commvault performance drastically then I would also share this as well more pro-actively. 

Thanks for sharing, @Sergey !
