Salesman in Germany who supports linux
--------------------------------------
I don't know the german market. But I do know that my distributor
have a presence in germany. Maybe you can call them and see if they
have a partner who can solve your need.
Germany

You can also call Sun Germany, and ask them if they have a suitable
partner.
Boot manager
------------
You can use std. sun boot loader or silo to boot solaris.
You can use silo to boot linux.
You can use std. sun boot loader to load silo from a linux partition
and then boot linux
Disk space is not usually a problem, though disk slot space is.
E.g. Seagate sells 70GB scsi disks, but you can only have six disks in
the chassi.
Raid
----
To my knowledge (I have not worked firsthand with raid) there are three
kind of raid out there:
software raid
raid with a raid card
"hw" raid
In software raid the os uses its own partitions so the should not be
any conflickt having both linux and solaris software raid
I don't know of any raid card that linux-sparc can use.
hw raid is os independent, the whole raid is presented as one big disk
Howtos:
/usr/share/doc/HOWTO/en-txt/Software-RAID-0.4x-HOWTO.txt.gz from the
doc-linux-text package is a good start. There are references there
also.
You cat go to http://www.linuxhq.com and search for raid, you will get
a list of howto's. I don't know which is best.
