It�s a great feature for a server environment, as the most common failure point in any server is typically the hard drive(s). By shifting that risk to a SAN, which is already highly redundant, monitored, and cared for, the thought is that you better protect your server infrastructure. Additional benefits for converged blade infrastructure (such as Cisco UCS or HP BladeSystem) is the ability to make a blade stateless � the blade can be replaced while still retaining its host identity, as it simply reaches out to the SAN to boot up. Having vSphere hosts that boot from SAN offers the unique opportunity to render any underlying blade hardware completely stateless. That is, a blade that is acquiring its personality from the blade infrastructure no longer has any unique identifiers or hosted information that keeps it tied down to the vSphere host personality.
