Protocol of IP scale-out switch planes

3

The switch plane protocol is the iWARP (Internet Wide Area RDMA Protocol). The iWARP is one of the technologies for high-performance transmission at 10GbE (10 Gigabit Ethernet) or higher rates. The iWARP is built on the basis of TCP/IP. It can utilize the existing network infrastructure. Through the RDMA over Ethernet technology, iWARP can provide data centers with integrated and low-latency switching services.

Scale-out switch planes are IP-based rather than PCIe-based
The reasons are as follows: 1. The IP switching technology is a common and mature practice in the industry. The IP protocol has been the de facto standard of data center standards. The IP switching complies with Huawei's ALL IP development trend. 2. For mid-range storage arrays, using IP switches can save the cost. PCIe switches are for specific purposes and bring higher costs. It is applicable to high-end storage. 3. The iWARP based on the IP protocol is a high-performance transmission technology. Its latency meets requirements of mid-range storage.

Default IP address of CX911 FC
The default IP address of the CX911 FC switching plane is provided below. Other switching planes or BMC is not configured with a default IP address. IP address: 192.168.1.100 Subnet mask: 255.255.255.0 Default gateway: 0.0.0.0

Management plane of the network planes for the eBackup
The management plane is divided into two sub-planes: backup management plane and production management plane. The backup management plane serves as the communication plane for eBackup to provide external services. You can use the IP address of this plane to log in to the eBackup backup management system through a maintenance terminal or a third-party system to configure and manage backup and recovery services. The production management plane serves as the communication plane between the backup server/backup proxy and the management plane at the production end.

Default IP address of CX912 FC
The default IP address of the CX912 FC switching plane is provided below. Other switching planes or BMC is not configured with a default IP address. IP address: 10.77.77.77 Subnet mask: 255.255.255.0 Default gateway: 0.0.0.0

Switching over the E9000 switching plane
