SAS FE host path configuration options

2 SAS FE host path configuration options
When an SC Series array is equipped with SAS FE ports, a total of eight ports (four per controller) are
available to connect host servers. To support MPIO, each SC Series array supports a maximum of four host
servers (two SAS ports per host).
SCv2000/SC4020 with SAS FE ports (4 ports per controller)
SCv3000/SC5020 with SAS FE ports (4 ports per controller)
Note: Dell EMC recommends configuring all hosts to use MPIO as a best practice regardless of the type of
transport in order to provide path redundancy. Carefully consider the risks before configuring any host to use
single-path. The customer assumes all risks associated with the design of their environment.
2.1 Multipath configuration
To provide path redundancy and ensure uptime, each host should be configured with at least two data paths
to external storage. With MPIO, if a data path fails, another data path provides the host uninterrupted data
access to SAN storage. This is particularly important for standalone Hyper-V or other Windows hosts that do
not have node-level redundancy.
Microsoft offers native MPIO support with SC Series storage that is quick and easy to configure. For more
information on MPIO for Microsoft Windows including Hyper-V, see the Dell EMC SC Series Storage:
