25.4.3 Calculation examples

A 1-unit configuration of a HiRDB/Parallel Server (with a FES, a DS, and 5 BESs), where pd_max_users=1000
```
 
{5[2  3 (0 + 0) + 1]
 + 1 (2  3  0 + 0 + 2) + 1 (0 + 1)}
 1000 + 1000=9000
```
The target number of ports is 9000.
A parallel unit configuration (unit 1: a FES, a DS, and 2BESs; unit 2: 3 BESs), where pd_max_users=900

Unit 1:
```
{2[2  3 (3 + 0) + 1]
 + 1 (2  3  3 + 0 + 2) + 1 (0 + 1)}
 900 + 1000=10900
```
Unit 2:
```
{3 [2  3 (2 + 1) + 1]
 + 0 (2  3  2 + 1 + 2) + 0 (1 + 1)}
 900 + 1000=9100
```
The target number of ports is 10,900 for unit 1 and 9,100 for unit 2.
