iSCSI target randomly gets dropped while doing backup (Hyper-v)

hello here our situation.

we bought cloud-storage product, company provided hyper-v (linux) vm.

the hyper-v mount physical hard drive, , use iscsi initiator connect vm ip.

i created shared folder drive(mapped iscsi initiator  )

the problem when run backup server, speed getting slower , slower, , when each file seems writting disk, drive down network（i can't access network @ time.）and backup job fail, after while drive again. (i can access local server, not network when problem happens)

i googled , found people have issue:

now sure it's problem 3 things ： hyper-v,  iscsi initiator, or linux vm provided us.

anyone has idea? can't see error event logs, when drive down network.

hi,

what’s os of hyper-v host server? what’s os version of hyper-v guest vm?

is hyper-v host server single server or cluster node server?

> hyper-v mount physical hard drive, , use iscsi initiator connect vm ip.

the hyper-v host connects cloud-storage product through iscsi? did mean connect vm, what’s vm used for? have installed latest integration service in vm?

i’m little confused how configured storage, please give more information understand scenario.
