IBM x3400 M3 Type 7378 / 7379 Accessories
The IBM x3400 server has been revised over three different generations (M1-M3). Disk drive options for the M2 Series are different than those for the M3 series. The best way to determine which server you have is via the 4-digit IBM feature code on the front of your server. Certain upgrade options are common across all three generations (such as disk drives), but other features such as CPU upgrades are not common across all generations.
