Rapid Deployment of PCIe 4.0 & 5.0
Servers have been dependent on PCIe 3.0 for nearly ten years. But with PCIe 4.0 processors now available and PCIe 5.0 coming soon, system designers are rapidly responding with designs to be supported by a broad array of processors, workload accelerators, smart I/Os, Field Programmable Gate Arrays (FPGAs), and Solid State Drives (SSDs).
Leveraging standards-compliant semiconductors and plug-and-play systems from Astera Labs can accelerate the shift to these blazing-fast processor speeds. The increased bandwidth that comes with PCIe 4.0 and 5.0 requires a high-speed reach extension solution to overcome signal integrity issues. Along with this, the disaggregation of resources (e.g. modular servers, storage/accelerator trays, etc.) forces endpoints physically further away from CPUs. These longer physical topologies need reach extension solutions to provide robust, high-speed connectivity.
The Aries Smart Retimer is designed to empower system designers to easily integrate a reliable reach extension solution and achieve plug-and-play interoperation without compromising interconnect topologies even at 32 GT/s speeds. This compensates for the signal lost in the transmission media and retransmits a fresh copy of the signal every time, effectively doubling the reach between root-complex and end-point devices.
