We're moving past the 100Mbps traffic levels and are looking for load balancers that have Gigabit ethernet ports, at least for the outbound aggregated connection.

I'm looking at the Cisco 1150x series. The 11501 is <$8K and I trust their stuff. The Radware hardware, which I used about 5 years ago, is not $20K+ (which is BS and turns me off entirely to them).

I'm not interested in a Linux solution - everything I've found so far is NOT able to handle active fail-over. I'd also prefer a 1u box, space is a premium.

Anyone have experience with the 1150x series?

I don't know... I've heard of it, but I'm not a Linux guru. Something I can look at

Well, it's more for failover services. For load balancing, you may want to take a look at LVS: http://www.linuxvirtualserver.org/
