"Storage Networks Explained" is one of the rare textbooks which have been translated from German to English. Please follow the link for further details on „Speichernetze“.
All authors publish in German and in international journals regularly. The fundamental German article "Speicher im Netz: Professionelle Speicherverwaltung mit SAN und NAS" which has been issued 2003 in c't is still quite useful.
In the year 2002 we have compiled various presentations for a German workshop, which might be useful for English readers as well
In the case you need the figures of the book for your own presentations, just send us an email to firstname.lastname@example.org.
