Planning the Fabric
Preliminary Considerations

| Preliminary Considerations |
|
| Before beginning to physically assemble a fabric, follow the steps below to be sure all |
|
| appropriate issues have been considered: |
Step | 1. | Read Chapter 1, “Overview,” on page 13 to get a basic understanding of HyperFabric and |
|
| its components. |
Step | 2. | Read this chapter, Planning the Fabric, to gain an understanding of protocol specific |
|
| configuration guidelines for TCP/UDP/IP and HMP applications. |
Step | 3. | Read “Configuration Overview” on page 63, “Information You Need” on page 64, and |
|
| “Configuration Information Example” on page 66, to gain an understanding of the |
|
| information that must be specified when the fabric is configured. |
Step | 4. | Decide the number of nodes that will be interconnected in the fabric. |
Step | 5. | Decide the type of HP 9000 system that each node will be (for a list of supported HP 9000 |
|
| systems, see the HP HyperFabric Release Note). |
Step | 6. | Determine the network bandwidth requirements for each node. |
Step | 7. | Determine the number of adapters needed for each node. |
Step | 8. | Determine if a High Availability (ServiceGuard) configuration will be needed. |
|
| Remember, If MC/ServiceGuard is used there must be at least two adapters in each |
|
| node. |
Step | 9. | Decide what the topology of the fabric will be. |
Step 10. Determine how many switches will be used based on the number of nodes in the fabric. Remember, the only configuration that can be supported without a switch is the
Step 11. Draw the cable connections from each node to the switches (if the fabric will contain switches). If you use an HA configuration with switches, note that for full redundancy and to avoid a single point of failure, your configuration will require more than one switch. For example, each adapter can be connected to its own switch, or two switches can be connected to four adapters.
