Hi Karyn, I've used ArrowPoints for very high trafficed web sites for several different companies, and they are one of my favorites. Their CS-150, which has two GigE ports, perfect for using it in a one-in one-out scenario. (I only use APs as load balancers, never as Layer 2 switches, I use something else to aggregate the traffic) They are an ASIC based LB, so they perform better at higher speeds than the PC based solutions (such as F5 and Cisco's LD) One of the most critical performance metrics with LB is connections per second, which the ArrowPoints have always done well for me. I've pushed over 200 Meg through them for FTP traffic, and 90 megs of HTTP traffic (the site just didn't attract more than 90 megs) I've never really had any problems with them, except for a hard drive failure or two. Even though they are a switch, they load their real-time OS from an internal IDE drive. An annoyance in an otherwise good machine.
