BEAVERTON, Ore. – July 11, 2012 – PCI-SIG®, the organization responsible for the widely adopted PCI Express® (PCIe®) industry-standard input/output (I/O) technology, today announced new updates to meet the evolving demands of a variety of computing markets from high-performance storage to ultra-thin and light mobile devices. Increased performance and new form factors frame the organization’s unique focus as it delivers new, innovative technologies built upon the 20-year legacy of the Peripheral Component Interface (PCI).

This year also marks 10 years of PCI Express specification development. As a leading standards organization, PCI-SIG is now turning its focus to driving I/O technology forward through advancements in PCIe-attached storage, new form factors and performance enhancements for the PCIe specification.

Increased Performance

• PCIe 4.0 technology is being developed to deliver 16GT/s, doubling the bandwidth over the PCIe 3.0 specification with seamless backward compatibility to all previous versions of PCIe technology. The PCIe 4.0 architecture is designed to double the data rate, while maintaining its position as a low-cost, high performance I/O technology. With the increase in clock rate designers can implement narrower links, thereby saving cost through pin reduction.
• PCIe-attached storage can achieve significantly higher bandwidth using processor-integrated PCIe 3.0 technology that is directly attached to storage sub-systems. The PCIe 3.0 standard is optimized for high performance solid-state drives (SSDs) in enterprise and client applications, and is well-positioned to address growing demands for increased storage I/O speeds.

New Form Factors

• PCIe OCuLink(SM), a small cable form factor supporting optical and copper optimized for internal and external enclosure usage, is being designed to offer bit rates starting at 8Gbps, with headroom to scale, and new independent cable clock integration. The internal and external connector supports up to four PCIe lanes, with all cables supporting 8GT/s. This provides up to 32Gbps in each direction within a four lane configuration; one lane and two lane configurations are also supported.
• Next generation form factor that will be part of the Mini CEM specification is being designed for the emerging ultra-light and thin platforms. A natural transition from the existing Mini CEM specification, this form factor is more flexible, smaller in both size and volume, offers better scalability and supports multiple technologies including Wi-Fi®, SSD and wireless wide area network (WWAN).
• The development of an electrical specification for the SFF-8639 connector which is intended for use in the growing PCIe-attached storage market.

PCI-SIG members can participate in the review of all PCI specifications before they are released to the industry. PCI-SIG members develop and maintain PCIe specifications, including the PCIe 4.0 specification, and are actively involved in defining compliance criteria and other technical enabling collateral.

As an additional and extremely valuable benefit of PCI-SIG membership, members are given the right to receive patent licenses from any other member of the organization with necessary claims of patent embodied within the specifications. These licenses may be limited in scope to an implementation of a particular specification, but must be granted to all members on reasonable and non-discriminatory terms.

PCI-SIG is the consortium that owns and manages PCI specifications as open industry standards. The organization defines industry standard I/O (Input/Output) specifications consistent with the needs of its members. Currently, there are more than 10,000 individuals participating from the PCI-SIG’s more than 800 industry-leading member companies.
