VRLI Setup Recommendations.

[virtual9999]

Dear All,

We have two Datacenters  and the vCenters in both sites are in enhanced linked mode. Would like to know the best way to implement Log Insight cluster. I believe a 3 node cluster ( 1 Primary node and 2 Worker nodes ) is the minimum supported / recommended configuration.

My Questions are :

1. Should we setup the 3-node cluster in each site Or just one cluster in any of the sites will do, as a single cluster can collect logs from both sites, as the vCenters are in linked mode ?

2. If one cluster is sufficient, how can we handle a disaster recovery situation, if the site goes down..

Appreciate any input.

Thanks in advance.

Hello,

1. Should we setup the 3-node cluster in each site Or just one cluster in any of the sites will do, as a single cluster can collect logs from both sites, as the vCenters are in linked mode?

• You can create 3 node Log insight cluster each site (Site A and Site B).
• Enable log forwarding from Site A to Site B log insights and from Site B to Site A log insights.
• Any planned activity / DR where a Log Insight is down you will not lose any data.

1. If one cluster is sufficient, how can we handle a disaster recovery situation, if the site goes down..

- You can integrate site vCenter into single 3 node Log Insight cluster.
- In case of Disaster Recovery situation - Log Insights will not collect data until the environment is down.
