Which storage option would best meet company objectives?

TestKing.com wants to increase disk capacity for their VMware vSphere environment.
Management mandates that:

(1) VMotion must work in this environment
(2) the existing LAN infrastructure must be used
(3) the storage must support VMFS volumes
Which storage option would best meet company objectives?

Overview of Using ESX/ESXi with a SAN
Using ESX/ESXi with a SAN improves flexibility, efficiency, and reliability. Using
ESX/ESXi with a SAN also supports centralized management and failover and load
balancing technologies.
The following are benefits of using ESX/ESXi with a SAN:
You can perform live migration of virtual machines using VMware VMotion.

Therefore this option would meet requirement (1) VMotion must work in this
environment

iSCSI SANs use Ethernet connections between computer systems, or host servers, and
high-performance storage subsystems. The SAN components include host bus adapters
(HBAs) or Network Interface Cards (NICs) in the host servers, switches and routers that
transport the storage traffic, cables, storage processors (SPs), and storage disk systems

Therefore this option would meet requirement (2) the existing LAN infrastructure must
be used

Use the vSphere Client to set up a VMFS datastore in advance on any SCSI-based
storage device that your ESX/ESXi host discovers. A VMFS datastore can be extended
over several physical storage extents, including SAN LUNs and local storage. This
feature allows you to pool storage and gives you flexibility in creating the storage
volume necessary for your virtual machine.

Therefore this option would meet requirement (3) the storage must support VMFS
volumes
