Question
A cloud architect is designing a distributed block storage solution that will support application HA. The solution will consist of 10 nodes with all SAS devices. There are five racks available in the data center. Each rack has a single top-of-rack access layer switch with sufficient bandwidth to the aggregate layer. Each node will have multiple connections to the local top-of-rack switch. The architect wants to provide a design that has the fewest number of storage pools maximizing the number of fault domains. How should the storage pools be designed?
