We have an Extended Cluster or Metrocluster solution where cluster(s) are located over multiple secure sites using FDDI and DWDM . What features of our networking infrastructure must be considered ?
2:
In a three-site Metrocluster solution, what role do arbitrator nodes perform? What software do they require to perform this role?
3:
Name at least five fundamental differences between Metrocluster and Continentalclusters?
4:
What does the concept of mutual recovery allude to when referring to Continentalclusters, and what implications does it have when designing the physical data replication infrastructure for such a solution?
5:
In a Continentalclusters solution, why is it more likely that data replication is performed asynchronously? What would be the impact of using synchronous data replication?
