Where to place the Superna appliance if we have 2 datacenters.  Is it possible to have 2 active appliances?  Does our license support having 2 appliances?

Description

  • Client has 2 data centers and would like to know if they can have to active appliances

Details

  • The license does not support having two appliances. It is recommended to put the eyeglass appliance on the cold site if you have a hot-cold configuration. If you have a hot-hot configuration then you can put it on either location. It is not recommended to have two active appliances as it would cause some issues due to both appliances accessing the same clusters.
