We Are Converging on the ESXi Architecture

Brand History 2007 ESX 3i

2008 ESXi 3.x (Free, Std, Adv, Ent)

2009 vSphere ESX (Std, Adv, Ent, E+), ESXi (Free, Std, Adv, Ent, E+)

2010 VMware Hypervisor (Free); vSphere ESX/ESXi (all paid editions)

VMware will converge on the ESXi architecture in mid 2011. End-of-

Sale ? End of Support: ESX 4.0 (with Service Console) will be supported at least through May 2014
