Craig, <<<I'll defer the loop questions to KJ. I haven't had a chance to fully research the Public/Private loop debate.>>> I think this is called passing the buck.<g> Pigboy, my understanding of these terminologies are as follows. If a company has only 127 devices in a FC/AL, it has 1 private loop. If a company has 350 devices in 3 FC/ALs, it has 3 private loops. If this company wants all these devices to be able to communicate with each other, it can use Arcxel's switch/hub (stealth mode) or of course Ancor's MKII to connect them together. My guess is that you can call these 3 loops(used to only talk to devices within its own loop) public loops.<g> My understanding of this 'stealth mode' is that it 'extends' the limitation of a single loop (which is 127 devices) to theoretically a much higher number of devices. But, then again, if 127 devices in a loop is already way too many in a real life situation, do you really want to have 1,000 devices participating in a large 'virtual' loop architecture? I called it 'virtual' because it is physically 3 FC/ALs. This is a network planning decision. But, the capability is there. MKII's theoretical upper limit is virtually none. KJ
