Setting Up SAS Cluster With PowerVault MD3000 and MD1000 Expansion
Enclosures
Task 1: Hardware Setup
Because SAS clusters can only be installed in a direct-attached cluster, they are
limited to two nodes only.
To configure your nodes in a direct-attached configuration (see Figure 5), 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 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 MD3000 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 MD3000 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 MD3000 storage enclosure.
5 (Optional). Connect two SAS cables from the two MD3000 out ports to the
two In ports of the first MD1000 expansion enclosure.
6 (Optional). Connect two SAS cables from the two MD1000 out ports to the
In-0 ports of the second MD1000 expansion enclosure.
NOTE: Refer to the MD3000 storage system documentation for information on
configuring the MD1000 expansion enclosures. The documentation is located at
