22.4.3 Calculation examples
- Example 1
- A 1-unit configuration of a HiRDB parallel server configuration (with a FES, a DS, and 5 BESs), where pd_max_users=1000
{5 ![[Figure]](FIGURE/ZUENG005.GIF)
[2 ![[Figure]](FIGURE/ZUENG002.GIF)
3 (0 + 0) + 1]
+ 1 (2 3 0 + 0 + 2) + 1 (0 + 1)}
1,000 + 1,000 = 9,000
The target number of ports is 9,000.
- Example 2
- A parallel unit configuration (unit 1: a FES, a DS, and 2BESs; unit 2: 3 BESs), where pd_max_users=1000
- Unit 1:
{2 [2 3 (3 + 0) + 1]
+ 1 (2 3 3 + 0 + 2) + 1 (0 + 1)}
1,000 + 1,000 = 12,000
- Unit 2:
{3 [2 3 (2 + 1) + 1]
+ 0 (2 3 2 + 1 + 2) + 0 (1 + 1)}
1,000 + 1,000 = 10,000
The target number of ports is 12,000 for unit 1 and 10,000 for unit 2.
