With that said, I've never encountered network interruption associated with taken vSphere snapshots. What OS are you running on the SQL server and which network adapter are you using? - Sean On Wed, Apr 20, 2016 at 7:01 AM, Tom Cass <t...@vaneerden.com<mailto:t...@vaneerden.com>> wrote: Need some design advice, We have recently started virtualization of our physical servers for the express purpose of reducing RPO RTO. So we have a Nimble SAN doing replication to a DR Nimble San. A VMware cluster at each end. The replication is uses a 1GB link. When we do synchronized snapshots of Nimble volumes which triggers a VMware snapshot which triggers the VSS writers in the appropriate guests. The snapshot succeeds and replicates But … If the guest is running MSSQL, most of the client PCs running Dynamics Accounting experience connection problems, causing errors and a restart of the client app. When pinging the virtual server during a snapshot at least 3 pings are lost. VMWare says this is normal. Is anybody out there running MSSQL on a virtual server where the SAN volumes are being replicated?
