HP Multi-Site Traffic Director Server Appliance SA9200 Getting Started Guide

Site Survey

Photocopy multiple copies of the Site Survey tables. You should

complete the tables before you begin the Quick Start Wizard.

Definitions

• Data Sites. Where your sites are located (both the network

topology and geographical location).

• ISP’s DNS. Your Internet Service Provider’s DNS needs to

include your name server information.

• Zones. The subdomain to which the host belongs.

• Services. A service is an application protocol that is offered on a

network. The device where the service is running is identified by

an IP address and a port is used to identify the protocol at the

designated IP address. A service contains an IP address and a

port. For example, 10.54.67.6:80 describes a service

consisting of a server’s HTTP application listening on port 80.

• Agents. The HP Traffic Directors at each site. (refers to either

HP Traffic Director Server Appliance, Models SA7200 and

SA7220; or HP e-Commerce Traffic Director Server Appliance,

Models SA8200 and SA8220) They are used to keep the SA9200

informed of the services it manages. The information it provides

to the SA9200 includes metrics, site status, response time, and

number of current connections of the server farm they are

balancing.

NOTE: If an ISV group is

on a remote site, identify

the ISV group by a site

name. If a group of

services are across sites,

identify the ISV group by

the service.

• ISV Group. Intelligent Site Verification (ISV) is used to directly

determine the availability of (a) a service or, (b) a service that is

balanced using a third-party load balancer. Methods of

verification include a site ping, TCP connect, and HTTP probe.

An ISV Group is a collection of services. All services in a group

share the same ISV polling parameters.
