On CV 11.20.9 we backuped Oracle DB from SPARC Solaris to MA RedHar8.4.

If we set “Optimized For concurrent LAN backups” on MA then speed = 1800 GB per hour, if we unset “Optimized For concurrent LAN backups”, then speed=5500 GB per hour.

All other settings are identical.

What changed in MA configuration when set “Optimized For concurrent LAN backups”?

After a long correspondence with support, it was found that on RHEL8 during backup with enabled compression, the network traffic from the client to MA does not decrease. Those, we see that on RHEL8 the network traffic is 2 times higher, and the backup time is 2 times longer compared to RHEL7. The reason for this has not yet been clarified.

@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.
