<div><p>Various rules and limits exist on how storage hardware can be attached
|
||
|
|
together. The limits may be determined by hardware design, architecture restrictions,
|
||
|
|
performance considerations, or support concerns. Your IBM<sup>®</sup> marketing representative can explain
|
||
|
|
these configuration limits and help you use them in your planning.</p>
|
||
|
|
<p>For each disk unit type, first plan for the I/O adapter that are needed
|
||
|
|
and then for the I/O processors that are needed. After planning the number
|
||
|
|
of I/O processors that are needed for all disk unit types, use the total number
|
||
|
|
of I/O processors to plan for the number of buses that are needed.</p>
