Chapter 4. Physical conguration

Physical conguration planning is your responsibility. Your technical support representative can help you

to plan for the physical conguration and to select features.

This section includes the following information:

• Explanations for available features that can be added to the physical conguration of your system

model

• Feature codes to use when you order each feature

• Conguration rules and guidelines

Conguration controls

Indicator features control the physical conguration of the storage system.

These indicator features are for administrative use only. The indicator features ensure that each storage

system (the base frame plus any expansion frames) has a valid conguration. There is no charge for these

features.

Your storage system can include the following indicators:

Expansion-frame position indicators

Expansion-frame position indicators flag models that are attached to expansion frames. They also flag

the position of each expansion frame within the storage system. For example, a position 1 indicator

flags the expansion frame as the rst expansion frame within the storage system.

Administrative indicators

If applicable, models also include the following indicators:

• IBM / Openwave alliance

• IBM / EPIC attachment

• IBM systems, including System p and IBM Z

• Lenovo System x and BladeCenter

• IBM storage systems, including IBM System Storage ProtecTIER

, IBM Storwize

V7000, and IBM

System Storage N series

• IBM SAN Volume Controller

• Linux

• VMware VAAI indicator

• Storage Appliance

Determining physical conguration features

You must consider several guidelines for determining and then ordering the features that you require to

customize your storage system. Determine the feature codes for the optional features you select and use

those feature codes to complete your conguration.

Procedure

1. Calculate your overall storage needs, including the licensed functions.

The Copy Services and z-Synergy Services licensed functions are based on usage requirements.

2. Determine the models of which your storage system is to be comprised.

3. For each model, determine the storage features that you need.
