SPARC: Installing a Sun StorEdge Netra D130/S1 Storage Array

If your host has only one SCSI port, see SPARC: Single-SCSI-Port Hosts. If your host has two SCSI ports, see SPARC: Dual-SCSI-Port Hosts.

SPARC: Single-SCSI-Port Hosts

When you install the storage array on single-SCSI-port hosts use the Netra E1 PCI Expander for the second host SCSI port. Figure 3–16 shows an overview of the installation. The storage arrays are cabled so that no single point of failure is in the cluster. Netra E1 PCI Expanders provide the second SCSI port for the 1RU form-factor hosts such as the Netra t1, x1, or t1 200.

To cable the storage arrays correctly, adhere to the bus-length restrictions that are listed in the documentation that shipped with your host adapter. In a Sun Cluster environment, this cable-length measurement includes the cables to both nodes. This cable-length measurement also includes the bus length that is internal to each storage array, node, and host adapter.
