Kerry,

<<< <<The switch weighs 15.5 pounds, and is fairly large for the number of chips on the board.>>
Another way of looking at this new MKII-8 is to compare it to Brocade Silkworm. I could be wrong, but I heard that the 8 port Silkworm is in the same box as the 16 port,ie. a stripped down version of the 16 port Silkworm ( can someone else confirm this? )as opposed to the MKII-8 which is total redesign versus the MKII-16. The Brocade Silkworm dimensions/weight are as follows:
Height: 3.438 inches
Width: 17.62 inches
Depth: 16.99 inches
Weight: 19 pounds
By contrast, Gigworks MKII-8 is:
Height: 1.72 inches
Weight: 17.4 inches
Depth: 13.6 inches
Weight: 15.5 pounds >>>

I looked up the MKII-16 specs:

Height: 3.36 inches
Width: 17.6 inches
Depth: 22.16 inches
Weight: 40 pounds

Ancor reduces the number of ASICs from 5 to 1 and the weight drops from 40 pounds to 15.5 pounds. I never realized ASICs could be so heavy.

The Brocade website shows the same weight and dimensions for the Silkworm and the Silkworm Express.

brocade.com

On a mildly interesting note, while the operating limits on altitude are the same for the Brocade and Ancor switches, the non-operating limit is only 13,000 feet for Brocade's switches vs. 50,000 feet for the MKII switches.

Also, I saw no mention of dual, hot-swappable power supplies for the Silkworms. Can anyone else confirm this? How many OEMs care about the apparent more rugged design of the MKII?
