I have 2 virtual servers setup where the client server "ClientA" connects to a SQL database on the database server "ServerSQL". I've found that on our VMware ESXi 6.0 farm that when I manually storage vmotion a large virtual server (2 to 6TB disks), the client server "ClientA" loses its network connection to the database server "ServerSQL" and shows a network error.
I believe that the storage vmotion traffic is being transferred over the LAN, and it seems to be somehow interfering with the normal server data network. How do I prove this and then fix it?
My Setup:
* 4x UCS B200 M4 servers setup as VMware hosts connecting via a virtual center server.
* Each host has 5 NICs:
---- vnic0 & vnic1 for VMOTION VLAN010 (IP: 192.168.1.1) and Management VLAN120 (IP: 10.96.12.51).
---- vnic2 is for all data VLANs for server network comms. VLAN010 (IP: 10.100.125.xxx)
---- vnic5 is for SQL Heartbeat network VLAN217.
---- vnic3 is for DMZ network VLAN101
Note that VLAN010 is defined as the VMOTION VLAN and a DATA VLAN on different NICs and I assume this is where the issue is?
