Explanation
Microsoft Multipath I/O (MPIO) is a Microsoft-provided framework that allows storage providers to develop multipath solutions that contain the hardware-specific information needed to optimize connectivity with their storage arrays. These modules are called device- specific modules (DSMs). The concepts around DSMs are discussed later in this document. MPIO is protocol-independent and can be used with Fibre Channel, Internet SCSI (iSCSI), and Serial Attached SCSI (SAS) interfaces in Windows Server. Asymmetric Logical Unit Access (ALUA), also known as Target Port Groups Support (TPGS), is a set of SCSI concepts and commands that define path prioritization for SCSI devices. https://kb.netapp.com/support/s/article/ka21A0000000d32QAA/asymmetric-logical-unit-access- alua-support-on-netapp-storage-frequently-asked-questions?language=en_US
