Overview

When ordering options for your xSeries server, note the Generation (usually designated with an M) or the feature code for your system. IBM uses the same x model numbers for multiple generations of servers. When ordering disk drives for servers purchased after 2005, pay special attention to SAS vs SCSI options (as well as LFF vs SFF choices) as IBM offered different back plane options for recently shipped systems.
