Hyper V file transfer kills the network

dear all,

        have 4 hyper v vm installations on 2 hp dl 380 g8 servers , have connected hp nsa 2040 san storage through 6 gbps fibre channel. physical machines clustered.

out of 4, 2 clustered hyper v's running microsoft dynamics ax 2012 r3 , have 2 clustered hyper v database server running ms sql 2012 r2.

the issue here app servers slow in communicating db server. hyper v's have dedicated 4 * 1gbps interface cards teamed , packets getting timed out. other machine in subnet communications proper.

when ever try copy file db server app server using smb share kills network, copy happen after copy completed network comes backup.

its strange scenario. app server 2 app server smb copy fine, , db db smb copy fine cannot copy between them.

can please help?

thanks,

hello,

this forum discussions , questions regarding profiles , microsoft's recognition system on msdn , technet sites. not products/technologies.

as it's off-topic here, moving question hyper-v forum.
