Re: [load balancing] Re: LoadBalancing products: Foundry ServerIron

[tony bourke <tony () vegan net>]

couple of drawbacks to the LD that other products do not suffer from:

* lack of cookie-based persistance support
* only works when servers and LB instance are on the same subnet (having
them on different subnets would have the LB acting as a router which is
great for packet filtering)
* lack of any other Layer 5 functionality
* is a server-based LB (If you pop one open, you'll see a pentium chip
inside) rather than ASIC based
