The outline of each component making up the SB is shown follows.
-
CPU
Three system buses called Intel ®
QuickPath Interconnect (QPI) are output from each CPU. Large scale
configuration (SMP) with up to 8 CPUs can be made, by connecting to other CPUs. A memory controller
is also mounted in CPU and
four SMI2 interfaces are output.
-
Memory Buffer (MB)
In PRIMEQUEST 2400E3/2800E3/2800B3/2400E2/2800E2/2800B2, the MB is a converter chip that is
connected to the CPU and memories.
