An  important storage requirement for virtual machine (VM) environments with more  than one physical machine (PM) server is shared storage. SAS has become a viable  interconnect along with other Storage Area Network (SAN) interfaces including  Fibre Channel (FC), Fibre Channel over Ethernet (FCoE) and iSCSI for block  access.
