vMotion of Exchange 2010 DAG member causes tempory loss of mail server connection
ESXi 5.1 with 16 Hosts (10G) Connection to Cisco 6500 and Fibre to EMC VNX 5300 SAN.
We have been having issue where when we vMotion a live Mailbox Server although it only takes less than a minute we lose several pings and it does not look like a clean memory swap to me even though over vNotion Network is on an isolated VLAN (VmkPings) all good.
Problem is users complain they lose access to mail and have to re-enter their login credentials.
The Mailbox Server is 2008 R2 16Gig Ram around 2 TB 5 x DB's
Appreciate and insite here

We have 8 Hosts each in Dell M1000e Blade Chassis.
All Hosts have 384Gig of Ram
Dell M1000e Chassis Have Force10MXL 10/40Gbe 10GE Chassis based switches so bandwidth should not be an issue.
We run VST so have multiple VLANS for VM's etc but vMotion on its own VLAN and VmkPings all good between hosts kernel ports.
What log is best to look at to see the results and process of the vMotion?
