Configuration Planning

Figure 5-2 shows a diagram of the planned network. As shown in the diagram, backup and DR are implemented without changing the company's existing network.

Figure 5-2 Planned network

IP connections are used between storage systems A and C and between storage systems B and C. Therefore, you need to plan front-end ports for IP replication links.

Table 5-1, Table 5-2, and Table 5-3 list the IP addresses planned for front-end ports on storage systems A, B, and C, respectively.

Table 5-1 IP addresses planned for front-end ports of storage system A (for replication links)

Front-End Port	IP Address	Subnet Mask
CTE0.A.IOM1.P0	172.16.19.30	255.255.0.0
CTE0.A.IOM1.P1	172.16.19.31	255.255.0.0
CTE0.B.IOM1.P0	172.16.19.40	255.255.0.0
CTE0.B.IOM1.P1	172.16.19.41	255.255.0.0

Table 5-2 IP addresses planned for front-end ports of storage system B (for replication links)

Front-End Port	IP Address	Subnet Mask
CTE0.A.IOM1.P0	172.16.21.30	255.255.0.0
CTE0.A.IOM1.P1	172.16.21.31	255.255.0.0
CTE0.B.IOM1.P0	172.16.21.40	255.255.0.0
CTE0.B.IOM1.P1	172.16.21.41	255.255.0.0

Table 5-3 IP addresses planned for front-end ports of storage system C (for replication links)

Front-End Port	IP Address	Subnet Mask
CTE0.A.IOM1.P0	172.17.20.30	255.255.0.0
CTE0.A.IOM1.P1	172.17.20.31	255.255.0.0
