PLX Technology, Inc. (NASDAQ:
PLXT), the leader in high-speed connectivity solutions for the enterprise and the home, today announced it will demonstrate PCI Express® (PCIe®) Gen3 switching over optical cabling at the upcoming PCI Special Interest Groups (PCI-SIG®) Developers Conference (DevCon), June 22-23, Santa Clara, Calif. The PLX® DevCon demonstration will be complemented by a presentation by PLX devoted to the evolution of PCIe becoming a box-to-box rack clustering solution for next generation data centers.
PCIe as a box-to-box interconnect for data centers using parallel optics will enable a wide variety of applications such as server, storage and GPGPU clustering. This demonstration showcases true peer-to-peer Gen3 high-performance at 8Gbps, per lane, between multiple endpoints represented as top of rack, bottom of rack, SSDs, Ethernet, and the Internet. PCIe over fiber promises to offer higher performance and greater distance at a lower price than standard PCIe cabling used today. PCIe Gen3 in an eight-lane configuration can transfer 64Gbps, which is a six-fold improvement over 10Gig Ethernet and with significantly less power required. PLX was the first company in the industry to demonstrate PCIe Gen3 silicon.
“Connecting subsystems using PCI Express over optical cabling makes sense both economically and technically for data centers and cloud computing, particularly when compared to converting PCI Express to Ethernet or InfiniBand for short reaches, then reconverting back to PCI Express -- steps that exact myriad cost, power and latency penalties,” said Brad Smith, senior vice president at Lightcounting, LLC, a market research company covering high-speed optical interconnect technologies. “PLX is demonstrating that PCI Express can be used to connect subsystems together efficiently through switches, such as PLX’s Gen 3 devices, which can be used to create local switching clusters that deliver low latency, cost and power consumption, with less complexity than alternative schemes.”
