David,
You're thinking of Local Director. Distributed Director is when
you have mirrored servers that are in difference geographic locations.
Local Director is when you have mirrored servers that are on the same
local segment. The Local Director feature is now supported in IOS as
'Server Load Balancing'.
As the name implies, server load balancing is used to distribute
traffic between multiple servers. Usually these servers would be on the
same logical segment (ip subnet), but you can also use NAT with SLB so
that the servers can be on separate segments. With the 'Automatic
Server Failure Detection' feature, the device running SLB monitors how
many TCP sessions fail to connect to a particular server in the farm.
If the failed sessions exceed a certain threshold, the server is
declared down and taken out of service.
For syntax and more info:
