Hi
I also use Veeam Backup 6.5 specifically and we experience very similiar issues with something classed as a Highly Transactional SQL Server (6CPU,48GB RAM, 2008R2 Enterprise)
I notice during the snapshot removal 95% that the SQL VM would freeze - this is very very very bad.
I Have even created a Snapshot Working LUN to store the Delta snapshot but it has made no differemce
I also noticed this happen when I created a snapshot of my vCenter server it ran very slow and then my pings to the server timed out and then the VM stopped all RDP connections to it - few seconds later the server came back
Is it normal for pings to stop to a VM being snapshot or snapshot removal happening in progress.
Also read a little on Stun times on a vm log but no real solution fixed
System Spec
Using ESXi5.0.2 -
2 x Dell Equallogic 6510X SAN (96 x 600GB Disks)
ISCSI10GB SAN Switch, setup for jumbo Frames
Dell MEM Plugin 1.0.2
Backing up to VMFS as Veeam doesnt backup RDM or
ISCSI Direct connect LUNS
The SQL server is where we need performance and 24/7 Operation but like mentioned i seen to have issues with Timeouts to my lower resource VM's too
Hopefully someone can suggest a fix
