I have a Sun Storage Array 7110.  This is an "integrated" appliance,
running custom hardware and custom software.  In the configuration GUI, on
the page where I configure the 4 gigabit network ports, there are - as with
everything else in the GUI - visual aids.  In this case, there are
schematic-style icons of four network ports on the left-hand side of the
page, with little green and yellow indicators for link and traffic
I know the green dots actually track the green LEDs on the back of the
chassis, i.e. they do show actual link status in (near-)real-time.
However, the yellow dots also flicker in a manner than *might* reflect the
physical LEDs... but I was never sure.

Today, while doing some unrelated maintenance on the unit, I got curious
and dug in.

I found this in the page's javascript:

akNetDevice.prototype.setActivity = function (active)

var dev = this;

> for (var i = 0; i < this.akno_widgets.length; i++)


> this.akno_timeout = setTimeout(function () {

if (dev.akno_timeout)


}, 100 + Math.random() * (active ?



*Despite* having found this, the flickering yellow dots *STILL* give me a
sense of satisfaction, a vague notion that "oh, OK, the network ports are

Someone at Sun actually listened to a UI designer, it would seem.  And yet
I now also feel cheated - I was hoping the UI team was geeky enough to
actually flash the browser window graphics in time with the hardware :).
