Looking at the stats on Bruno, I'm not 100% sure the machine will support booting from a USB device. I'm looking at this through the eyes of someone who knows mostly personal PC's. My experience with servers is slight. I'm not sure whether BIOS boot configurations on servers would be typically more or less robust than personal computers.

Bruno's old. With a decent RAID array, there are many personal computers these days that would have the same, if not more capacity. It's a dual single-core machine. 2.66G individual cores is technology that predates USB2.0 if I recall correctly. This is why I am unsure if it will take USB as a boot source.

Having said that, a boot CD would almost certainly be doable.


This is not Bruno though, it is Thumper: Sun Fire X4500 (2 x dual-core 2.6GHz Opteron, 16 GB RAM). Slightly newer.



The X4500 will boot CD/DVD and USB. If the upgrade hasn't been done to the x4540 (main board swap, and some firmware) then the boot drives are the first two from left to right looking at it from the front. The HPC center I was working at had the first two drives configured raid 1 and the other 46 as data and spares. If the upgrade has been done, then the boot drives will be the first two starting from the left, front to back.

The upgrade should be completed if possible. This was to address the fact that the boot drives where on the same controller. No controller no boot. With the upgrade you could still boot to the mirror and would be out the drives on that controller. Proper config would allow a controller failure and still leave the machine running. This pretty much requires a physical drive map...ie pen and paper to keep everything straight as multiple arrays means drives are scattered all over heck!!

I may still have the old drive maps for controllers to physical locations...
