This may be old news, but when I was looking at the MKII-16 spec, I came across this Interoperability listing: It is Ancor's goal to continually add interoperability. This list will grow. Adapter Vendors Ancor (IP only) Adaptec Emulex Interphase Jaycor QLogic Systran Chip Sets Adaptec Emulex HP's Tachyon QLogic SUN OC+ Storage Vendors Ciprico Series 7000 RAID (firmware v2.1 for class 3, v3.0 for class 1) CLARiiON Arbitrated Loop JBOD (Seagate Barracuda and Cheetah Arbitrated Loop drives Unisys Abritrated Loop JBOD Boxhill Arbitrated Loop JBOD * requires public loop firmware for disc drivers (available from Seagate) Hub Vendors Emulex Arbitrated Loop hub Gadzoox Arbitrated Loop hub Vixel Arbitrated Loop hub Maybe those rumored relationships with Brocade are not hard and fixed for many years.

I never realized ASICs could be so heavy. Chips do weigh a lot once you add the power supplies. ;-) - nic

Greg, I might be able to answer some of your questions regarding the MKII switches. (I have seen the MKII-16.) Here are the dimensions of the two Ancor switches and Brocade's SilkWorm: (I took these from your and Kerry's previous posts, and corrected a couple of typos.) Brocade Silkworm: Height: 3.438 inches Width: 17.62 inches Depth: 16.99 inches Weight: 19 pounds Ancor Gigworks MKII-8: Height: 1.72 inches Width: 17.4 inches Depth: 13.6 inches Weight: 15.5 pounds Ancor Gigworks MKII-16: Height: 3.36 inches Width: 17.6 inches Depth: 22.16 inches Weight: 40 pounds The Ancor MKII-16 is a very industrial type switch. It has a relatively large chassis, and is built like a tank. There is also a surprising amount of empty space, mostly in the vertical direction. My speculation is that due to cooling (and possibly power supply size) concerns, the MKII-16 could not have been made any smaller in height. The MKII-8 appears to be a totally different animal. The power supply has probably been redesigned, and the main board has been redesigned for certain. Notice that the fiber optic connector placement on both switches is in a zig-zag pattern. (One connector is above the centerline, and the next one is below it.) This adds structural rigidity to the entire board/connector assembly, reduces space requirements, and improves reliability. Ancor also takes extra precautions to make sure that the connector assemblies don't work loose over time. The bottom line is that the MKII-8 appears to offer much of the ruggedness of the MKII-16, but at a substantially lower price point. I doubt that we will see a plastic box version of the switch in the near future, due to cooling and rigidity requirements. Craig
