Nodes
A node is an individual service on a physical server that consists of
an IP address and a port number.
Pools
A pool is a group of nodes that is mapped to a corresponding virtual
server. Pools allow you to scale large networks that contain many
nodes. Pools may be configured independently and associated with
virtual servers in complex ways.
Each pool has its own load balancing method. When associated with
a virtual server, the pool cannot be deleted from the SLB
configuration.
Pools must be added before, and deleted after, the virtual servers
that reference them. If a pool is not associated with a virtual server,
it is not used for load balancing.
To create a pool, use this command:
create slb pool <poolname> {lb-method [round-robin
| ratio | priority | least-connections]}
To add nodes to a pool, use this command:
configure slb pool <poolname> add
<ipaddress>:<L4Port> {ratio <ratio> | priority
<priority>}
To delete nodes from a pool, use this command:
configure slb pool <poolname> delete
<ipaddress>:<L4Port>
Virtual Servers
Virtual servers are the backbone of the SLB configuration. They
determine which groups of servers, or other network equipment, are
targeted for server load balancing. Before you configure virtual
servers, you need to know:
• The forwarding mode for your network design
• The name of the pool
• The virtual IP address
