As part of some current SharePoint 2010 on FlexPod work, I have been setting up some VMware ESX servers to boot from SAN. After a few quick searchs I found a few very good posts online.
BootFromSAN101 with Cisco UCS
UCS Boot Whitepaper
I thought the BootFromSAN 101 post had a good outline. So I decided to take it a few steps futher and create a video on NetApp storage provisioning, Cisco Nexus 5000 zoning and Cisco UCS boot from SAN for VMware vSphere ESXi 4.1.
