HP Matrix Operating Environment Software - Manual (Page 56)

At least one network must be selected. All networks in the server group are displayed. Only a load
balancer that has access to the selected networks will be allocated.
The attributes of a load balancer that you can select for a server group are as follows:
High Availability
Requests a load balancer in a redundant configuration. This
means that there are two or more load balancers that back
up and monitor each other. If one load balancer fails,
another takes control so that users do not notice any
disruption of service.
SSL Capable Requests a load balancer on which an SSL certificate is
installed, which allows un-encrypted HTTP to be used over
the local network between the load balancer and the servers.
This improves performance on the servers.
Cookie Based Session Persistence Requests a load balancer with cookie based session
persistence. Persistence ensures that requests from a single
user are always distributed to the server from which they
started. Cookie based session persistence provides a
stateless solution for session persistence by storing all session
data in a cookie in the user's browser.
Source Address Session Persistence Requests a load balancer with source address session
persistence, or simple session persistence, which directs
session requests to the same server based on the source IP
address of a packet.
Requesting a load balancer for an organization
Load balancers can be “reserved” for use by a particular organization or user by:
•
Specifying a tag in the ioexec add loadbalancer command, and specifying that tag
on the Load Balance tab in infrastructure orchestration designer
•
Ensuring that all networks visible to a load balancer are assigned to a specific organization.
In a template that has a logical network N that is visible to a load balancer, the actual load
balancer selected is determined by the network allocated to N by IO.
Creating and deleting a logical load balancer group
After a service has been deployed, IO administrators or an IO user can use the following ioexec
commands to create, manage, and delete logical load balancer groups.
