A few years back we order two Cisco 4510 to replace our two Cisco 4006. At the time I am thinking about moving to iSCSI away from Fiber Channel.
So you can select diffrent Engines with this product and when I have this types of options I buy the BIGGEST. and I was thinking I was getting the best (Its Cisco its the best, its cost $120,000).
So I had my self Cisco Catalyst 4500 Series Supervisor Engine V-10GE with 8 x 48 Port 1000mbits PoE line cards.
2/3 years later I find out..
a) the line cards have 48 x 1000mbits dont support Jumbo Frames (up to 9216 bytes) when I was thinking that Jumbo Frames was a Engine feature.
b) Per slot switching capacity is only 6 Gbps when the total for switch 136 Gbps. I have 10 slots... so why dont I have a min of 13.6 Gbps per slot? If I have a 48 Port line card I should be able to pump thu 48 Gbps.
c) Every 6 ports on 48 Port line card shares 1 Gbps. So I can only get 8 Gbps, but does not matter as the slot only supports 6 Gbps.
So I got 24u (1/2 a rack) of tin.. which cost $120,000.. and does nothing for iSCSI. I really think I have to review my want to buy Cisco. I think Cisco is amazing company but I really hoping for a lot more.
Plus this not the only product. If you played with Cisco Router 3640 it can support up to 8 E1 interfaces, but it can deal with more then 2 1/2 with H.323.
