Chapter 4. Determining physical configuration and features
Use these general guideline for determining and ordering the feature codes that
you need to customize the XIV system.
Procedure
To determine what features to order, answer the following questions:
1. How many XIV systems do you need?
2. Which XIV model configuration best fits your needs?
3. How many data and interface modules do you need?
4.
What size disk drive do you need?
5. Does the installation site meet the physical site requirements for the XIV
systems and features that you plan to order? For example:
v Can you space the racks to allow for sufficient floor strength?
v Is there adequate cooling capacity to handle the new equipment?
v Is sufficient power available?
v Do you need 30A or 60A power cables?
v Is water cooling required?
