We have a fairly large VMware infra with 5 vcenters and 5 ZVM’s all linked together running v5 update 1 all running embedded db’s. Our vCenters (5.5 and 6.0) manage 50 to 100 ESXi hosts and 1000 to 2000 VM’s. We currently have 300 VM’s protected by Zerto moving up to 500 in the next few months.
Our main two protected vCenter ZVM’s have embedded DB sizes in the range of 64Meg (zvm.sdf) and we seem to have pretty good UI performance.
I’m curious as to any indications as to when the embedded database causes problems and should I be planning to move them to external SQL at some point. I’d rather keep them as one self contained entity if possible.
On a side note, has anyone found a reliable way to cover the ZVM’s for DR?
I would say you’re pretty much at the point where a external DB would be warranted. Is your environment recently deployed? The DB will likely grow over time. The embedded DB has a size limit of 4GB and when you begin to fill that up (>60%) you may see performance degradation.
You can find official guidance in the document “Sizing – Zerto Virtual Replication” located under (MyZerto -> Technical Documentation).
Let me know if you have any added questions.
