The Brocade ServerIron ADX Series pattern builds the BMC Discovery load balancer model based on additional details obtained via SNMP for the following configured items:

Real Server Port
Virtual Server
Virtual Server Port
VirtualServer Bind

Any configuration no longer reported is removed from the model.

Load Balancer Model

Brocade ServerIron ADX Series uses the following conceptual model:

Virtual Server and Virtual Server Port (n) - (n) Binding rule (n) - (1) Real Server and Real Server Port.

A pair of Virtual Server and Virtual Server Port is modeled as a LoadBalancerService.

A Binding rule is modeled as a LoadBalancerPool.

A pair of Real Server and Real Server Port is modeled as a LoadBalancerMember.

Supported service states

Enabled
Disabled

Supported balancing methods (algorithms)

leastconnection
roundrobin
weighted

Modeled Load Balancer Components

Load Balancer Instance

The pattern creates a Load Balancer Instance with the following attributes:

key	A hash of the device key and load balancer type.
type	A load balancer type (ServerIron).
name	A %LB_TYPE% on %device.name%.
version	A version of the device OS.

The pattern models a network service relationship between the device and the Load Balancer Instance.

Load Balancer Service

The pattern creates a Load Balancer Service with the following attributes:

key	A hash of the instance key, service ip address, and port.
name	A virtual server name.
ip_addr	A virtual server IP address.
port	A virtual server port.
type	A virtual server type.
state	A virtual server state.
_config_hash	Contains a hash of the Service Name, Service IP address, port, type and state.

The pattern models a containment relationship between the Load Balancer Instance and a Load Balancer Service.

Load Balancer Pool

The pattern creates a Load Balancer Pool with the following attributes:

key	A hash of the service key and pool.
name	Contains service name and service port.
algorithm	The Balance Method.

The pattern models a containment relationships between the Load Balancer pool and Load Balancer Instance.

The pattern also models a containment relationships between the Load Balancer pool and Load Balancer Service.

Load Balancer Member

The pattern creates a Load Balancer Member with the following attributes:

key	A hash of the instance key, IP address and port of the real server.
ip_addr	A server IP address.
port	A server port.
name	A pair of server IP address and port.
state	Real Server status.
_config_hash	Contains a hash of the Real Server ip address, port and state.

The pattern models a containment relationship between the Load Balancer Pool and a Load Balancer Member.
