How do I group compute nodes to control workload placement?

I've a set of old Dells and a set of new HP SandyBridge class systems as my compute nodes. I want to group or tag these nodes as two different groups so that I can deterministically place a workload on old Dells or on new HP systems.

This is similar to having two zones (east and west), how do I control whether my workload runs in east zone or in west zone?

You want to take a look at the http://docs.openstack.org/trunk/openstack-compute/admin/content/host-aggregates.html (aggregate) functionality.

Briefly, aggregates allow you to define groups of compute nodes with different characteristics. You can then create flavors that ask for the different characteristics and the scheduler will place them accordingly.
