SAS Cluster Setup for the Dell PowerVault MD3000 17
Cabling Your SAS Storage System
SAS clusters can only be installed in a direct-attached cluster and are limited
to two nodes only.
To configure your nodes in a direct-attached configuration (see Figure 3-2),
complete the following steps:
1
Connect one SAS cable from a port of the SAS controller of node 1
to the In-0 port of RAID controller 0 in the MD3000 RAID enclosure.
2 Connect one SAS cable from a port of the other SAS controller of node 1
to the In-0 port of RAID controller 1 in the MD3000 RAID 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 MD3000 RAID enclosure.
4 Connect one SAS cable from a port of the other SAS controller of node 2
to the In-1 port of RAID controller 1 in the MD3000 RAID enclosure.
