We have three ESXi servers connected to our Nimble storage using a Brocade Fibre Channel switch, each ESXi server connects to Nimble storage with individual zone as: ESXi1_Nimble, ESXi2_Nimble, ESXi3_Nimbe.
A few months after this configuration was done, we added a physical server for Veeam B&R v12 as backup server and repository, which is also a backup proxy server. This is connected to the same FC switch and I created zone between the Veeam B&R server and the Nimble storage as: VeeamBR_Nimble
And most recently, we added a HPE tape library to this mix for GFS tape backups. Added the library to the FC switch and created a zone between VeeamBR_HPETapeDrive.
Each night, the Veeam B&R server runs backup jobs then stores into its local repository (D: drive). Then it runs backup to tape, which writes from the Veeam B&R backup repository into tape drive. I have already configured "Direct storage access" while configuring Backup proxy's Transport mode.
The backup jobs do not use the FC switch path, but uses 1Gbps [nbd] network traffic as evident with this type of message on completed backup jobs: "Using backup proxy VMware Backup Proxy for disk Hard disk 1 [nbd]"
As we can tell from my FC zoning, there is no zone that connects Veeam B&R server and each ESXi server. Should I create zones between each ESXi and Veeam B&R as ESXi1_VeeamBR, ESXi2_VeeamBR, ESXi3_VeeamBR for the backups to utilize the FC switch?
And what are your thoughts on creating zones between the ESXi servers and the HPETapeDrive?
Thank you in advance for your help here.
