the
In-0 port of RAID controller 0 in the PowerVault MD32 xx
storage enclosure.
2 Connect one SAS cable from the other port of the SAS controller of
node 1 to the
In-0 port of RAID controller 1 in the PowerVault MD32 xx
storage enclosure.
3 Connect one SAS cable from a port of the SAS controller of node 2 to the
In-1 port of RAID controller 0 in the PowerVault MD32 xx storage enclosure.
4 Connect one SAS cable from the other port of SAS controller of node 2 to
the
In-1 port of RAID controller 1 in the PowerVault MD32 xx
storage enclosure.
5 If applicable, connect two SAS cables from the two PowerVault MD32 xx
storage enclosures
Out ports to the two In ports of the first PowerVault
