Below diagram shows a traditional 3 tier highly available cluster with 3 Hyper-V nodes and 2 shared storage nodes (storage in Active-Passive/ Active-Active mode) all connected via network switches.
Compute
*Hyper-V nodes are running on DELL PowerEdge R630 rack servers
Networking
*Shared storage is accessed via MPIO over two separate VLANs (61 and 62)
*VM traffic is over NIC teaming (Switch independent and dynamic)
*Live migration/ cluster network is also teamed together
Storage
*We are using DELL PowerEdge R320 with Open-E DSS V7 as storage nodes
*Each node has 8 x 10K SAS drives with RAID 5
*Storage can be either in Active-Passive/ Active-Active cluster mode
*In Active-Passive mode, only one of the storage nodes will be active. That means resources of only one storage node will be utilized at a time
*In Active-Active mode, both servers will be active and serving storage traffic
