From: eeb4u on
I am upgrading the cache to 16GB on a ST6580 and I have added 4 memory
modules to each controller, but there are also two small plugs (Flash
memory modules) that should be installed too (one in each controller).
There are four slots in each controller and each controller has one
similar plug in a slot called USB 3. These parts can only fit in one
of the remaining three. The question is, which one?

Anybody have any insight? Sun wants to come out and install this for
me.....
Regards,

Mike
