[Techtalk] netbooting Linux raid

[Ricardo Dalceno]

Hi Carla,


I believe that booting from a USB device like a memory key, flash cards or
something like these would be better then booting from network. Also, you
will *not* need a boot server and you may use all your disks to storage.

It could be a good idea to build something like those 'router/firewall in a
disk' but with tools that you would like to have in a storage system. Plus
it might be practical to small networks.

Anyway, if you want, you still can boot from network, but if your boot
server fails for any reason, you will have problems to access your storage
until the boot server is up and running again.

I hope this is what you were looking for.
