VMware vSphere (formerly VMware Infrastructure), is VMware's first cloud operating system. It is able to manage large pools of virtualized computing infrastructure, including software and hardware, and it is fully supported by LIO.
vSphere 4 and vSPhere 5 have been tested with LIO with IBLOCK, FILEIO and PSCSI backtores storage objects. Physical storage objects work because the underlying SCSI low-level driver (LLD) supports SPC-3, SPC-4 and T10 WWN for vSphere MPIO.

Reservations
vSphere 4 uses SPC-3/SPC-4 Persistent Reservations (PRs) for controlling I_T Nexus access to a LUN.
vSphere 5 uses VAAI ATS to support much finer granularity LUN access control and synchronization.
Multipath
vSphere 4 uses SPC-3/SPC-4 Asymmetric Logical Unit Assignment (ALUA) for intelligent multipathing. ALUA implements outer-nexus OS dependent multipathing (via MO_SET_TARGET_PGS) from the SCSI Initiator port that allows ALUA Access States to be set on per SCSI Target Port basis. The LIO ALUA implementation conforms with SPC-4 r17.
Certification
The LIO has obtained "VMware Ready" certifications for VMware vSphere 4 with Buffalo, Netgear[1] and QNAP[2] storage appliances.
VMware
VMware, Inc. (NYSE: VMW) is a provider of virtualization software.[3][4][5] The company was founded in 1998 and is based in Palo Alto, California. The Company is majority owned by EMC Corporation (NYSE: EMC).
VMware's desktop software runs on Microsoft Windows, Linux, and Mac OS X. while VMware's enterprise software is hypervisors for servers, VMware vSphere, VMware ESX and VMware ESXi are bare-metal embedded hypervisors that run directly on server hardware without requiring an additional underlying operating system.
