Configuration of internal cluster network IP range

| Changelog Number | 741 |
| Type | New Feature |
| Status | Resolved |
| Fix Versions | EXASOL 6.0.0, EXASolution 5.0.15 |
| Resolution Date | 2016-06-21 |
(please only use fix version 6.0.0 for this, as this feature is only internal for AWS in versions 5.0.x)
Hint:
It is possible to define almost any netmask prefix for networks. However, only 8, 16, and 24 are supported at cluster installation time (due to implementation complexity). Thus, the description only shows these three example.
Configuration of internal cluster network IPs
At cluster installation time, the private network (IP address and netmask/prefix length) can now be configured.
Limitations:
- The private network configuration cannot be changed later (e.g. via EXAoperation).
- The prefix length must be 8, 16, or 24.
- The maximum node number and the number of additional private networks depend on the prefix length, as shown in the table below:
| Prefix Length (Network netmask) | Maximum node number | Maximum number of additional private networks |
|---|---|---|
| 8 (255.0.0.0) | 32766 | 191 |
| 16 (255.255.0.0) | 126 | 191 |
| 24 (255.255.255.0.0) | 30 | 2 |
