In addition to traditional networked storage that this topic covers, VMware supports virtualized shared
storage, such as vSAN. vSAN transforms internal storage resources of your ESXi hosts into shared
storage that provides such capabilities as High Availability and vMotion for virtual machines. For details,
see the Administering VMware vSAN documentation.
Note The same LUN cannot be presented to an ESXi host or multiple hosts through different storage
protocols. To access the LUN, hosts must always use a single protocol, for example, either Fibre Channel
only or iSCSI only.
Fibre Channel (FC)
Stores virtual machine files remotely on an FC storage area network (SAN). FC SAN is a specialized
high-speed network that connects your hosts to high-performance storage devices. The network uses
Fibre Channel protocol to transport SCSI traffic from virtual machines to the FC SAN devices.
To connect to the FC SAN, your host should be equipped with Fibre Channel host bus adapters (HBAs).
Unless you use Fibre Channel direct connect storage, you need Fibre Channel switches to route storage
traffic. If your host contains FCoE (Fibre Channel over Ethernet) adapters, you can connect to your
shared Fibre Channel devices by using an Ethernet network.
