SAS FE host path configuration options
9 Dell EMC SC Series Storage with SAS Front-end Support for Microsoft Hyper-V | 3026-CD-WS | V3
With SAS FE, up to four host servers can be connected to each SC Series array in any combination of
standalone hosts or cluster nodes. Figures 5 through 10 show several different MPIO cabling options for
Hyper-V hosts and clusters.
Each color in Figures 5 through 10 represents a separate SAS FE fault domain. Fault domains protect host
servers against a single path or single controller failure.
Each SAS FE fault domain consists of two SAS FE ports. To group the SAS FE ports, group SAS FE port 1
on each controller to create SAS fault domain 1, group SAS FE port 2 on each controller to create SAS fault
domain 2, and so on. A corresponding SAS FE port from each controller must be used when creating a SAS
FE fault domain as shown in the figures.
Note: SAS FE supports multiple dual-port SAS HBAs per physical host server (up to four per host if the host
server has available PCIe slots). If more than one SAS HBA is installed in a host server, the HBAs must be
identical. Each dual-port HBA must be connected to only one fault domain as shown in Figure 11 and Figure
12.
Note: The SCv2000 and SC4020 arrays utilize a 2U chassis. The SCv3000 and SC5020 arrays utilize a 3U
chassis. SAS FE functionality is similar on supported SC Series models.
