56 SPARC Enterprise Mx000 Servers Administration Guide • August 2009
Note – On midrange and high-end servers, SPARC64 VII processors run only with
certain versions the Solaris OS and XCP firmware (beginning with XCP 1070). For
specific information about minimum OS and firmware requirements, see the Product

The first firmware to support the newer entry-level server is the XCP 1080 firmware.
For specific information about minimum OS requirements, see the Product Notes for
your server.
