Access time to memory and I/O can be reduced because controllers for memory, PCI Express, and 10Gbit Ethernet are inside CPU chip,
Two memory controllers inside CPU chip helps improve memory access time because each memory controller can directly access four memory DIMMs.
With PCI Express2.0 interfaces incorporated I/O performance is much improved.
SPARC T4 with Network Interface Units (NIU) for 10Gbit Ethernet inside helps increase network throughput due to its direct access to 10Gbit Ethernet –Solaris Container may be your choice environment if you need a high network throughput.
*1 XAIU (10 Gigabit Attachment Unit Interface) is the standard for 10Gigabit Ethernet Interface.
