By using IP to transport block storage replication traffic
instead of fiber channels, you avoid the extra hardware costs associated
with fiber-based block disk replication.
Before you begin
- Review the concepts that are presented in Network configuration overview.
- Review and complete, if required, the steps in Network configuration planning.
- You must be assigned the Hardware administration role with permission to Manage hardware resources (Full permission) to perform these steps.
- An IP connection is required to enable the connection of storage controllers. Complete the steps
in Connecting storage controllers to an IP network. Make sure that
the IP addresses that you use are resolved by your DNS server.
- Ensure that the services and ports in the following topic are
not blocked by firewalls:
About this task
This task is optional. Complete the steps in this task only
when using IP to handle all block storage replication traffic.
Procedure
- Click .
- To configure IP addresses, under Optional,
expand the node for Additional IPs for storage device for
block disk replication.
- In the Management Port section,
define a port to be used for storage device management. In sections Replication
Port 1 and Replication Port 2,
define ports for data traffic replication use.
- In the IP Address field, specify
the IP address of the port.
IP addresses for the Management Port, Replication
Port 1 and Replication Port 2 can
be on the same customer data VLAN or associated with different customer
data VLANs.Important: The configuration will fail
if the IP address is already defined in another IP group.
- In the VLAN field, specify the
VLAN ID of the VLAN selected in the VLANs and Links section
with the type IP Group.
- In the Gateway field, specify
the gateway for the VLAN.
- In the Netmask field, specify
the netmask for the VLAN.
- After specifying all required information, click Save.
- Click .Verify
that three new jobs of the type storage controller ports and
of action configureIPBaseReplication are running
and complete successfully.
- To verify connectivity, you can ping the IP address that
you configured from another machine on the same VLAN.
