good day, sorry to re open this topic after "some" weeks
I'm working on a customer infrastructure using VPLEX and experiencing this issue:
when the veeam proxy reads data in SAN mode with no storage integration, the speed is sometimes good (i.e. 50 MB/s per process, with many in parallel) but sometimes so slooooowww (I mean less than 500 KB/s).
Apparently it happens randomly, but this different speed is often observed for some vmdk inside the same VM (disk 1 is read fast, disk 2 pretty slow).
Any idea on what could be going wrong? Today I will try to get some logs and probabily open a SR.
Currently I have workarounded the issue forcing the proxy to work in NBD (management interfaces are on 10Gig and speed is satisfying for me: personally I would use NBD but the customer seems to prefer the direct SAN for traffic separation)
