The Sun Blade X3-2B was previously named the Sun Blade X6270 M3 Server Module. This name might still appear in the software. The name change does not indicate any change in system features or functionality.
The new name identifies the following:
X identifies an x86 product.
The first number, 3, identifies the generation of the server.
The second number, 2, identifies the number of processors.
The alpha character, B, identifies the product as a blade server.
