In the NAS scenario, multiple physical ports are typically bonded and assigned IP addresses for service data communication during service configuration on Huawei Data Storage System. What are the differences between configuring one IP address and multiple IP addresses for the bond port?
The following table compares the reliability, service performance, and management complexity of configuring one IP address and multiple IP addresses for a bond port accessed by multiple hosts.
| Scenario | Impact | ||
| One IP Address | Multiple IP Addresses | ||
| Reliability | IP address exceptions, such as IP address conflict and accidental deactivation or deletion | All host services are affected. | Some host services are affected, but access is still possible through other IP addresses. |
| Service performance | High-end storage system | Services are processed by a single controller. | IP addresses are distributed across multiple controllers to process services in parallel, achieving controller load balancing. |
| Mid-range or entry-level storage system | Services are processed by a single controller. | Services are processed by a single controller. | |
| Management complexity | Service IP address management | Low | High |
Therefore, despite the complex IP address management, you are advised to configure multiple IP addresses for a bond port to improve reliability and performance. Note the following precautions:
- Ports on different controllers cannot be bonded.
- Ports across interface modules can be bonded when TOE is disabled; however, this configuration will affect storage system performance. You are advised not to bond ports across interface modules.
