your SLAs and business requirements, you need to have a fast and reliable storage
network. Your storage network is a key component that delivers performance and also
data protection and integrity. You need to ensure that your storage network is scalable,
highly available, and that it can meet the performance needs of all your databases and
applications. When it comes to storage protocol choice, the determining factors are
much less about performance and much more about other business requirements, existing
investments, and storage vendor support.
VMware supports four different primary storage protocols for virtual machines: Fiber
Channel (FC), Fiber Channel over Ethernet (FCoE), iSCSI, and NFS. Any of these
supported protocols can be used to support your SQL Server databases. Each protocol
has different requirements for the physical network; however, logically they are
architected similarly to provide performance and availability.

sample logical diagram of a storage network connecting vSphere hosts and storage
devices.
