This page documents the steps necessary to initialize site replication between two AIStor deployments. The procedures assume at least two existing AIStor installations. Only one of the two sites can have any data at the time of setup. All other sites must be empty of buckets and objects. All sites must otherwise having the following matching configurations: AIStor Server version Key Management Server for Server-Side Encryption Identity Manager Ensure each peer site has a Load Balancer, Reverse Proxy, or similar network control plane component to handle routing connections to its AIStor Server nodes. Using a single node hostname for a peer site creates a single point of failure for site replication where replication can fail if that single node goes down.

Object tiering is the moving of the data of an object from one set of hardware to another set of hardware. This is often done as a cost-saving measure, keeping more expensive and performant hardware for the newest or most accessed objects while placing other objects to less expensive and less performant storage solutions. Retrieving a tiered object When AIStor moves an object to another tier, the object’s metadata remains on the primary tier while the object’s data moves to the secondary tier. When AIStor needs to serve a tiered object, it transparently retrieves the object from the secondary tier.
