Installing a Sun StorEdge 3120 Storage Array
For the procedure about how to install and cable the storage arrays, see the Sun StorEdge 3120 SCSI Array Quick Installation Guide. For a URL to this storage documentation, see Related Documentation.
Note –
In the configuration that is outlined in Figure 3–1, you must mirror the Sun StorEdge 3120 storage array against another storage array. This storage array need not be a Sun StorEdge 3120 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.

SPARC: Sun StorEdge D2 Cabling Diagrams
SPARC: Installing a Sun StorEdge D2 Storage Array
You can install a single storage array by using a split-bus configuration. You can install two storage arrays by using a single-bus configuration.
Figure 3–24 SPARC: Installing a Sun StorEdge D2 Split-Bus Configuration: An Example
To use a single storage array in a Sun Cluster environment, you must use the split-bus configuration.
As Figure 3–24 shows, the split-bus configuration requires that the storage array contain two Environmental Service Modules (ESM). Each ESM is connected to two nodes. Each ESM controls half the disks in the storage array and the data is mirrored by using a volume manager.
Figure 3–25 SPARC: Installing a Sun StorEdge D2 Single-Bus Configuration: An Example
As Figure 3–25 shows, the single-bus configuration requires two storage arrays that each contain a single Environmental Service Module (ESM). The ESM controls all disks on the storage array in which it is installed and the volume manager implements mirroring between the two storage arrays. Each ESM must be connected to two nodes.
SPARC: Adding a Sun StorEdge D2 Storage Array
Ensure that the entire bus length that is connected to the storage array is less than 12 m. The bus length includes the cables from the ESM to the host adapter. See the documentation that shipped with your hardware for internal bus length.
