Planning the Fabric

Preliminary Considerations

 

 

Preliminary Considerations

 

 

Before assembling a fabric physically, do the following to address all of

 

 

the appropriate issues:

Step

1.

Read Chapter 1, “Overview of the HyperFabric Product,” on page 1, 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 69, “Information You Need” on

 

 

page 71, and “Configuration Information Example” on page 74, to

 

 

understand how to configure the fabric.

Step

4.

Decide the number of nodes that will be interconnected in the fabric.

Step

5.

Decide the type of HP 9000 system for each node (for a list of supported

 

 

HP 9000 systems, see the HyperFabric Release Notes available at

 

 

http://docs.hp.com/hpux/netcom/index.html#HyperFabric.

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. If ServiceGuard is used, each node should have at least two

 

 

adapters.

Step

9.

Decide the topology of the fabric.

Step 10. Determine how many switches will be used based on the number of nodes in the fabric. The only configuration that can be supported without a switch is the node-to-node configuration (HA or non-HA). HyperFabric supports meshed switches up to a depth of four switches, starting with the following versions of the HyperFabric software:

For HF2 switches: software versions B.11.00.11, B.11.11.01, and B.11.23.00.
