Alfresco really does not care whether NAS or SAN is used for storage. In a dockerised deployment, the only thing that matters is that you provide it with a volume mount to handle the alf_data / contentstore folder, and/or index for SOLR. So as long as you provide a volume mount that is located on a SAN-backed filesystem, you don't have to do anything else really in Alfresco.
Thank you for clearing my concern for Alfresco on SAN. Actually I am planning to deploy Alfresco on SAN for Disaster Recovery in a production eviornment. Since my DR server and Production Server both will be connected to a shared Storage so if my Production server fails my DR server will be automatically UP as I will be using SAN. My database will be replicating continiously through logical replication.
I just wanted to confirm that if my strategy is technically possible or not?
