The common technique for increasing redundancy, high availability, and load efficiency for a vSphere environment is to arrange ESXi hosts into vCenter cluster. One of the most important requirements for clusters is creating a VMware shared storage. There are several ways to do this:
- SAS interfaces on storage servers and an ESXi host
- Fibre Channel
- iSCSI
- Virtual SAN (vSAN)
Let’s take a look at each of the approaches for creating a VMware shared storage and compare them.
