Tonight, while waiting for the /home array to resync, [NTU], [TRS] and I 
discussed the possibilities of doing this for $0 rather than trying to 
convince the committee to spend more money.

To this end, we've loaded up Manduba's chassis (the E4000) with six of the 
US-II boards from Manbo (the E6000), and the clock board which allows the 
backplane to run at 100MHz. This has been hooked up to the system drive 
array from Manbo, so if the machine POSTs successfully the plan is to 
re-use the old Manbo install (at least in the short term) to get the FC 
arrays back online.

This machine will have a gigabit network connection provided the fibre 
isn't broken (fingers crossed!) and will run the FC arrays at gigabit 
speed, as well as finally using the LA-sponsored chips to their full 
potential, so speed shouldn't be too much of an issue.

(I have even less idea about Sun and Solaris than anything else, so any of 
the above might be wrong.)
