Connecting the Management Host and Data Hosts

This chapter describes Sun StorEdge 6130 array cable connections for hosts. It contains the following sections:

Connecting the Management Host

The management host directly manages Sun StorEdge 6130 arrays over an out-of-band network. This section describes how to connect the physical Ethernet and power cables to the management host.

Before You Begin

Before you begin, ensure that the two Ethernet cables are used to connect the management host. These requirements are outlined in the Sun StorEdge 6130 Array Site Preparation Guide.

Connecting the Ethernet Cables

1. Locate the Ethernet ports for Controller A and Controller B at the back of the controller tray (FIGURE 4-1). FIGURE 4-1 Ethernet Ports for Controller A and Controller B

2. Connect an Ethernet cable to each Ethernet port.

3. Connect the other end of each Ethernet cable to a LAN that can be reached by your management host (preferably on the same subnet).

Connecting Data Hosts

You can connect data hosts to access the Sun StorEdge 6130 array through Fibre Channel (FC) switches to the array or directly to the array.

Connecting Data Hosts Through External Fibre Channel Switches

You can connect the Sun StorEdge 6130 array to data hosts through external FC switches.

Before you connect data hosts, check that the following prerequisites have been met:

The FC switch has been installed and configured as described in the vendor's installation documentation. (See the Sun StorEdge 6130 Array Release Notes for a list of supported switches.)

Interface cables are connected and routed between the host bus adapters (HBAs), switches, and installation site.

Fiber-optic cables (2-meter or required length) are available to connect the array to the FC switch.

1. Locate the host ports (SFP transceivers) at the back of the controller tray (FIGURE 4-2). FIGURE 4-2 Host Connections

2. Connect each fiber-optic cable to the host port of Controller A and Controller B.

Caution - Fiber-optic cables are fragile. Do not bend, twist, fold, pinch, or step on the fiber-optic cables. Doing so can degrade performance or cause data loss.

3. Connect the other end of each cable to the external switch as shown in the graphics that follow. FIGURE 4-4shows the external switch with cross-connections. Note that this configuration is not yet supported for use within a SunCluster. FIGURE 4-3 Connecting Data Hosts via a Switch

4. Connect the cables from the switch to the HBAs for each data host.

Connecting Data Hosts Directly

A direct point-to-point connection is a physical connection in which the HBAs are cabled directly to the array's host connectors.

Before you connect data hosts directly to the array, check that the following prerequisites have been met:

Interface cables are connected and routed between the HBAs and the installation site.

Fiber-optic cables (2-meter or required length) are available to connect the array to the data host HBAs.

The Sun StorEdge 6130 array has four host connections, two per controller. To maintain redundancy, connect one data host to both Controller A and Controller B.

1. Locate the host ports at the back of the controller tray (FIGURE 4-2).

2. Connect a fiber-optic cable to each host port on Controller A and Controller B.

Caution - Fiber-optic cables are fragile. Do not bend, twist, fold, pinch, or step on the fiber-optic cables. Doing so can degrade performance or cause data loss.

3. Connect the other end of each fiber-optic cable to the HBAs (FIGURE 4-5and FIGURE 4-6). FIGURE 4-5 Direct Connection to a Single Host With Dual HBAs

Next Steps

After you have connected the management host and data hosts, you are ready to install the management and data host software as described in Chapter 5.
