High speed, wide bandwidth, crossbar

SPARC Enterprise mid-range and high-end servers incorporate high speed and wide bandwidth crossbars inherited from supercomputer high speed interconnect technology.

Direct and symmetric crossbar connections between CPU, memory and I/O enables max. 737GB/s throughput (theoretical figure SPARC Enterprise M9000), maximizing bandwidth and minimizing latency.

SPARC Enterprise with leading crossbar technology provides the optimum platform for demanding high performance applications such as OLTP (OnLine Transaction Processing), data warehousing and line-of-business application servers.

High speed data transfer between CPU and memory

Direct connections between CPU, memory and I/O are controlled by crossbars. Data transfer rates are improved by parallel memory access from multiple CPUs.

High speed data transfer between CPU Memory Boards and I/O Boards

In high-end models, crossbar interconnects occur between CPUs, Memory Boards and I/O Boards. These crossbars enable uniform access from any CPU to any unit of memory, regardless of memory or CPU mounting location.

The distances between CPU Memory Boards and I/O Boards are minimized, enabling low latency and high performance with I/O accesses.

The dual crossbars in SPARC Enterprise M9000 each have 368.5 GB/s bandwidth. If one crossbar fails, the system can restart using the remaining crossbar after isolating the faulty crossbar during reboot.
