The CS800 chassis is a pretty big box, about the size of a Cisco 7507. Last I checked it had 4x RAM capability of the CS100 (and 2x of the CS150). Since the major source of my woes appeared to be memory related, it didn't look like a good jump $-wise and u-wise (I'm guessing at 16u ?) to serve the same number of devices. As I remember, it's a 10 slot chassis - two for the management modules. How many slots do you have populated on your chassis? Are they all GigE or 10/100s or a mix?
I seem to remember the folks over at Andover being disgusted with the Arrowpoint boxes after a recent denial-of-service attack. You might try searching on Slashdot; I think they posted a pretty fair criticism of the boxes. (Slashdot was using CS100s, as I recall). -- Timothy Brown tcb@ga.prestige.net /* I speak for myself, not my company. */
