VMware/NetApp Snapmirror transfer size question
Posted on 2012-03-14
We just stood up a new Virtual Infrastruture with a NetApp filer. We have a PROD and DR filer in place onsite. We have our snapmirror relationships setup and have started monitoring the traffic flow for these relationships to make sure we can handle the network load when the mirrors update every night. The plan is to move the DR filer offsite once this study is done.
We have a total of 36 VMs. 95% Windows 2008 R2. We place 10 VMs per datastore, with the exception of one datastore for the file server (different backup needs). Out of these servers, we have 2 SQL servers.1 small SQL server for a one off app, the other is the main SQL server, 10+ DBs, heavy I/O.
Between 5 datastores, we run one nightly backup via NetApp VSC. The total transfer size for all 5 datastores last night was 316GBs. This is a "normal" production day here meaning nothing was done out of the ordinary that would have infalted the deltas.
Does this sound "typical"?
