You have two very large databases supporting OLTP workloads which run on multiple small-blade style servers in a cluster and which require optimal latency for I/O.
You plan to migrate them to a Database Machine once a capacity planning exercise is finished.
The database backup strategy requires that backups are written directly to media.
High availability requirements state that you must be able to survive node failures at any time.
Which three Database Machine components or features would you recommend to support these requirements?
