SAS Cluster Setup for the Dell PowerVault MD3000 17
Before You Begin
Verify that the following tasks have been completed for your cluster:
• All hardware is installed in the rack.
• All hardware interconnections are configured.
• All virtual disks/LUNs, RAID groups, and storage groups are created on the
storage system.
• Storage groups are assigned to the cluster nodes.
CAUTION: Before you perform the procedures in the following sections, ensure
that the system hardware and cable connections are installed correctly.
Cabling Your SAS Storage System
SAS clusters can only be installed in a direct-attached cluster, hence they 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.
PowerVault MD3000 • Two CAT 5e/6 cables connected to a LAN (one from
each storage processor module).
• Two SAS connections to each PowerEdge system
node using a SAS 5/E controller. See "Cabling Your
SAS Storage System" on page 17.
Gigabit Ethernet switch • One CAT 5e/6 connection to the private Gigabit
NIC on each PowerEdge system.
• One CAT 5e/6 connection to the other Gigabit
Ethernet switch.
