Sunnyvale, Calif.PLX Technology Inc. announced four new PCIe switches targeting servers, enterprise storage, control planes, and ultra-gaming, while featuring what the company says is the highest PCIe switch lane counts in the industry.
The PLX ExpressLane PEX 8696 (96 lanes, 24 ports), PEX 8680 (80 lanes, 20 ports), PEX 8664 (64 lanes, 16 ports) and PEX 8649 (48 lanes, 12 ports) are PCI-SIG PCIe 2.0 (Gen 2) specification-compliant switches. They support x16 port configurations and non-transparency (NT), as well as visionPAK and performancePAK development tools.
The PLX devices also implement game-changing Multi-root and Multicast features. These large switches allow designers to build switch fabrics, redundant backplanes and large IO/storage drawers without having to deal with high latency, high power consumption and bandwidth limitations associated with use of multiple smaller switch chips.
The standard Multicast feature was added to the new PLX switches to increase performance by reducing CPU load. Multicast delivers data to a group of destinations simultaneously, thus efficiently using memory bandwidth at the source and relieving the host from copying the data to multiple locations sequentially.
For use in backplane applications, PLX switches support fully non-blocking internal fabric and full peer-to-peer data exchange at full Gen 2 line rate without any host assist. PEX 8696 supports a total raw throughput of up to one terabit per second in full-duplex mode at PCIe Gen 2 rates.
Pricing: The PEX 8696, PEX 8680, PEX 8664 and PEX 8649 volume prices are $148.15, $127.75, $105.85 and $78.40, respectively.
Availability: Sampling in the second quarter of 2009.
Datasheets: PEX 8696, PEX 8680, PEX 8664 and PEX 8649.
