While using virtualization

While using virtualization to share SAN adapters on a server, how does Node Port ID Virtualization (NPIV) differ from Virtual SCSI (vSCSI) related to the use of multipathing software?（）

• ANPIV and vSCSI both require multipathing in VIO Server only. 
• BNPIV requires multipathing software on client LPARs, vSCSI requires multipathing software on VIO Server. 
• CNPIV requires multipathing software on VIO Server, vSCSI requires multipathing software on client LPARs. 
• DNPIV requires multipathing and MPIO software on VIO Server LPARs, vSCSI requires multipathing software on VIO Server and MPIO on client LPARs.
