PCI-X is a high performance bus that is designed to meet
the increased I/O demands of technologies such as Fibre
Channel, Gigabit Ethernet and Ultra3 SCSI. PCI-X capabilities include:
- Up to 133 MHz bus speed
- 64-Bit bandwidth
- 1GB/sec throughput
- More efficient bus
operation for easier interface.
- Split Transactions allows
an indicator device to make only one data request and relinquish the bus.
Instead of constantly needing to poll the bus for a response.
- Byte Count that enables
indicator to specify in advance the
specific number of bytes requested, eliminating the inefficiency of
- Backwards compatibility
