Hi Team, I have 3 esxi5.0 hosts running on IBM servers using netapp FCOE storage. We are configuring SRM for fail over to DR site. we have about 20VM. 3 or them are MSSQL and the rest are application servers. we found the snapshot is more than 25GB every day created in SAN ,which means data changes of the OS VMDK is too large. it's not SQL data because the data is in RDM disks and not in the datastore. I am wondering what caused so large data changes because the OS suppose has no changes everyday, or very minimum. Is there a way to reduce this to less than 1GB? because the large data change will take too long time to sync to DR site via a very limited WAN link. or is the memory of VMs got changes? I tried to change the memory reservation to 4GB for one VM,but got an error ,though the other VM changes had no issue. the host has 64GB memory and assigned 50GB to the VMs and still have some un-assigned. resource should be enough.
error is
Reconfigure virtual machine
myappserver1
Insufficient resources to satisfy configured
failover level for vSphere HA.
any advice please?Thanks so much!
regards
KF
