• FC SAN 1 with its larger number of hosts and capacities is spread over four nodes all with maximum storage capacity. There are at least eight streams per node to provide good throughput performance • All the NAS target backups have been grouped together on node 5 and 6 on 10GbE - these could be VMWare backups which generally require a backup to NAS target. Again all NAS targets are balanced equally across nodes 5 and 6 and, in the event of failover, performance would be well balanced at around 50% of previous performance for the duration of the failed-over period. • FC SAN 2 has smaller capacity hosts connected via FC. Nodes 7 and 8 are the least loaded hosts, so this couplet is the obvious candidate for use as the replication target. • Keep it simple and easy to understand - that's the key.
