Page 27 from vsphere-esxi-vcenter-server-50-installation-setup-guide.pdf
the three valid options for *installing* ESXi in a scripted manner are PXE, boot from CD, and boot from USB. http://pubs.vmware.com/vsphere-50/topic/com.vmware.vsphere.storage.doc_50/GUID- 9004389B-E2C0-4BE5-811C-E4886E3B7450.html states that booting through a Fibre Channel host bus adapter (HBA) or a Fibre Channel over Ethernet (FCoE) converged network adapter (CNA) is supported, but this is not an installation option, but a way of running ESXi in a diskless manner after the installation.
