Oracle Coherence accomplishes failover without data loss by synchronously maintaining a configurable number of copies of the data within the cluster. Just as the data management responsibility is spread out over the cluster, so is the responsibility for backing up data, so in the previous example, each of the remaining four servers would have roughly 25% of the failed server's data backed up on it. This mesh architecture guarantees that on server failure, no particular remaining server is inundated with a massive amount of additional responsibility.

Oracle Coherence prevents loss of data even when multiple instances of the application are running on a single physical server within the cluster. It does so by ensuring that backup copies of data are being managed on different physical servers, so that if a physical server fails or is disconnected, all of the data being managed by the failed server has backups ready to go on a different server.

Lastly, partitioning supports linear scalability of both data capacity and throughput. It accomplishes the scalability of data capacity by evenly balancing the data across all servers, so four servers can naturally manage two times as much data as two servers. Scalability of throughput is also a direct result of load-balancing the data across all servers, since as servers are added, each server is able to utilize its full processing power to manage a smaller and smaller percentage of the overall data set. For example, in a ten-server cluster each server has to manage 10% of the data operations, and – since Oracle Coherence uses a peer-to-peer architecture – 10% of those operations are coming from each server. With ten times that many servers (i.e. 100 servers), each server is managing only 1% of the data operations, and only 1% of those operations are coming from each server – but there are ten times as many servers, so the cluster is accomplishing ten times the total number of operations! In the 10-server example, if each of the ten servers was issuing 100 operations per second, they would each be sending 10 of those operations to each of the other servers, and the result would be that each server was receiving 100 operations (10x10) that it was responsible for processing. In the 100-server example, each would still be issuing 100 operations per second, but each would be sending only one operation to each of the other servers, so the result would be that each server was receiving 100 operations (100x1) that it was responsible for processing. This linear scalability is made possible by modern switched network architectures that provide backplanes that scale linearly to the number of ports on the switch, providing each port with dedicated fully-duplexed (upstream and downstream) bandwidth. Since each server is only sending and receiving 100 operations (in both the 10-server and 100-server examples), the network bandwidth utilization is roughly constant per port regardless of the number of servers in the cluster.
