Connecting to the 2510 Array with Other Topologies

A P P E N D I X D

This appendix describes connecting data hosts to the Sun StorageTek 2510 Array with topologies other than the basic ones listed in Chapter 4. It contains the following section:

Connecting to the 2510 Array with Other Topologies

Connecting to the 2510 Array with Other Topologies

Chapter 5 showed the two most common duplex cabling topologies:

Direct topology

Network topology

This section shows more examples of the above and adds:

Single-controller topology (not recommended)

Mixed topology

Host Cabling Configurations - Single Controller

The following figures demonstrate single controller host cabling configurations:

FIGURE D-1: Direct Connection - One Host Connected to a Single Controller

FIGURE D-2: Direct Topology - Two Hosts Connected in a Single Path

FIGURE D-3: Fabric Topology - Two Hosts Connected to the Controller Through a Switch

FIGURE D-4: Mixed Topology - Three Hosts Connected Through a Switch or Connected Directly

FIGURE D-1 Direct Connection - One Host Connected to a Single Controller

Figure showing a direct connection: One host connected to a single controller.

2	NIC 1	5	Host Port 2
3	NIC 2	6	Controller A

FIGURE D-2 Direct Topology - Two Hosts Connected in a Single Path

3	NIC 2	6	Controller A

You can connect one or more hosts to a controller tray. The hosts can run the same operating system or each host can run a different type of operating system.

Host Cabling Configurations - Dual Controller

The following figures demonstrate dual controller host cabling configurations:
