BIG-IP Software on the Dell PowerEdge 1655MC Blade Server System
BIG-IPĀ® Platform Guide for the DellĀ® PowerEdge 1655MC Blade Server System 1 - 13
Setting up a basic BIG-IP software configuration
The most common application of the BIG-IP software is to distribute traffic
across an array of web servers that host standard web traffic, including
e-commerce traffic. Figure 1.1, on page 1-14 shows a configuration where a
BIG-IP system load balances two sites: www.siterequest.com and
store.siterequest.com. The www.siterequest.com site provides standard
Web content, and the store.siterequest.com site is the e-commerce site that
sells items to www.siterequest.com customers.
To set up load balancing for these sites, you need to create two pools that are
referenced by two virtual servers, one for each site. Even though the sites
are related and may even share the same IP address, each requires its own
virtual server. This requirement exists because each site uses a different port
to support its particular protocol: port 80 for the HTTP traffic going to
www.siterequest.com, and port 443 for the SSL traffic going to
store.siterequest.com. Note that this is true even when there are both a port
80 and a port 443 on the same physical server, as is the case with Server 2.
For specific information on how to create pools and virtual servers, see the
BIG-IP Reference Guide, Part III, The High-Level Network.
Important
In this example, we use only non-routable IP addresses. In a real topology,
you have to include virtual server IP addresses that are routable to the
Internet.
