ElasticXL clusters
Draw the members at each site and label the Single Management Object (SMO) role. On a site, one member receives traffic and distributes it among members. Study the difference between adding inspection capacity to a site and designing for loss of an entire site. A management HA peer alone cannot supply enforcement capacity.
Before onboarding a new appliance, check the R82 platform requirements and supported interface topology. Inspect the member's join state, software alignment and site assignment. In a lab, send representative flows and examine evidence from the participating members. A cabled appliance is not necessarily a ready member.
