PCI-SIG Board of Directors approved PCI-X 2.0

Today PCI-SIG Board of Directors approved the official public release of PCI-X 2.0 protocol portion and the posting of the ´release candidate´ for the PCI-X 2.0 electrical portion to PCI-SIG official website. Together, both parts contain complete information for chip and system developers, required for making new PCI-X 266 and PCI-X 533 products.

PCI-X 2.0 specifications define two new PCI-X card variants: PCI-X 266 and PCI-X 533. The former feature 266 MHz bus clock rate and provide over 2.1 GB/sec bandwidth. PCI-X 533 operate at up to 533 MHz clock rate, providing over 4.2 GB/sec bandwidth. It is more than enough for 10 Gigabit Ethernet, 10 Gigabit Fibre Channel, Serial Attached SCSI, Serial ATA (SATA), InfiniBand, RAID and cluster interconnects for servers and workstations.

PCI-X 2.0 expands the popular PCI-X 1.0 specifications with such features, as byte counts and split transactions, PCI-X 2.0 also supports Error Checking and Correction (ECC).

The new standard is backward compatible with previous PCI versions, enabling faster PCI-X 2.0 motherboards and systems deployment.
