Note – The SPARC64 VII processors are supported only on
M3000/M4000/M5000/M8000/M9000 servers that run certain versions of XCP
firmware (beginning with XCP 1070) and Solaris software. For specific information
about these minimum software and firmware requirements, see the latest version of
the Product Notes (no earlier than the XCP 1070 edition) for your server.
FIGURE 2-9
shows an example of a mixed configuration of SPARC64 VI and SPARC64
VII processors.
FIGURE 2-9
CPUs on CPU/Memory Board Unit (CMU) and Domain Configuration
A mix of SPARC64 VI and SPARC64 VII processors can be mounted on a single
CPU/Memory Board unit, as shown in CMU#2 and CMU#3 in
FIGURE 2-9
. And a
single domain can be configured with a mix of these SPARC64 processors, as shown
in Domain 2 in
FIGURE 2-9
.
An M4000/M5000/M8000/M9000 server domain runs in one of the following CPU
operational modes:
■
SPARC64 VI Compatible Mode – All processors in the domain – which can be
SPARC64 VI processors, SPARC64 VII processors, or any combination of them –
behave like and are treated by the Solaris OS as SPARC64 VI processors. The new
capabilities of SPARC64 VII processors are not available in this mode. Domains 1
and 2 in
FIGURE 2-9
correspond to this mode.
