Preparing for Production Deployment
*When deploying a main database server or a catalog node to production: It is recommended to remove the default 50GB and 60GB VMDKs included in the CTERA Portal OVA, and attach a VMDK sized 2% of the overall cloud storage you intend to allocate for the service. Prior to going to production, contact CTERA Support to evaluate whether the attached drive's performance meets CTERA's main database and catalog node performance requirements.
*When deploying an application server to production: It is recommended to remove the default 60GB VMDK included in the CTERA Portal OVA.
*When deploying a document preview server to production: You may keep the existing drives included in the CTERA Portal OVA.
