Key Features:
4x Dedicated Gen5 x4 M.2 Ports
Near-Zero Latency
Universal M.2 Versatility: NVMe & PCIe Accelerator Modules
Maximum Bandwidth: Leverages native CPU bifurcation (x4/x4/x4/x4)
Mission Critical Reliability
Near-Zero Latency. Zero-Distance Purity. Absolute Gen5 Velocity
As the industry transitions to PCIe Gen5, IT architects are encountering a common physical bottleneck: the lack of onboard NVMe connectivity. With most enterprise platforms offering only one or two native Gen5 M.2 slots, scaling high-speed infrastructure has historically meant compromising on signal integrity or latency. The Rocket 1604L, an Gen5 x16 M.2 Expansion Add-In-Card, was engineered to address this growing problem.
The Signal Integrity Revolution - Motherboard-Grade Stability: Unlike traditional passive bifurcation cards that suffer from signal attenuation at 32GT/s, the Rocket 1604's integrated Astera Labs Gen5 Retimer actively terminates incoming signals, eliminates electrical noise, and re-transmits a bit-perfect, "clean" signal to your devices. The result? 100% data integrity across all four M.2 ports - the exact same performance and reliability as a native motherboard-integrated slot!

Maximize Your Inference Throughput: Industry-Leading 4-AIPU Compute Density
Why the Rocket 1604L is the Architect's Choice
For AI Architects, the Rocket 1604L represents the ultimate solution for maximizing compute-per-watt and compute-per-slot. By leveraging a high-density PCIe Gen5 x16 host interface, this AIC transforms a single slot into a quad-core AI powerhouse, hosting up to four M.2 AI Acceleration modules (AIPUs) in a parallel, non-blocking architecture. This 4-AIPU Density allows for the simultaneous processing of massive data streams—such as multi-channel 4K video analytics or high-frequency sensor fusion—without the thermal and power overhead of a traditional full-length GPU. Equipped with Astera Labs’ PCIe Gen5 Retimer technology, the Rocket 1604L ensures each accelerator receives a pristine, low-latency data path, delivering deterministic performance and eliminating the "GPU starvation" that plagues passive expansion solutions. Now, you can pack server-grade inference capabilities into compact 1U and 2U Edge chassis, effectively quadrupling your TOPS (Tera Operations Per Second) without expanding your physical footprint.
Near-Zero Latency: Operating at the Physical Layer (PHY), the 1604L provides a "transparent pipe" to the CPU. re-clocks and regenerates a fresh, perfect data stream.
Universal M.2 Versatility: Engineered for more than just storage, the 1604L’s transparent PCIe architecture supports the full spectrum of M.2 PCIe Accelerator Modules (TPUs/NPUs) and high-speed NICs alongside the latest Gen5 NVMe SSDs.
Proven M.2 Cooling Solution Eliminates Thermal Throttling: Comprised of a full-length aluminum heat sink, integrated low-decibel cooling fan, multi-layered thermal padding, & ventilated PCIe bracket
40% Smaller, 100% Faster: Space is at a premium in compact AI servers. The Rocket 1604L is over 40% shorter than standard 4-bay M.2 cards.
Intelligent Firmware Layer with Smart Monitoring & Transparent Performance:
-
Bus Lane Allocation: Ensure each drive receives maximum bandwidth.
-
Power Consumption: Track real-time storage power draws.
-
Health Status: Get board-level diagnostics to preemptively manage hardware lifecycle.
Zero Friction Integration: Native OS Driver support results in a true Plug-and-Play solution
Pro-Class M.2 Cooling Solution
Rocket 1604L AICs are equipped with a powerful, ultra-efficient hardware cooling solution comprised of an anodized aluminum heatsink with an integrated low-decibel cooling fan, multiple layers of high-efficiency thermal padding, and a ventilated PCIe bracket. The solution rapidly transfers waste heat away from the hosted M.2 modules and Switch chipset, and keep the performance-sapping threat of thermal throttling at bay.
Technical Note: The Rocket 1604L requires a host platform that supports PCIe bifurcation (x4/x4/x4/x4).
The Rocket 1604L is widely compatible with industry standard M.2 SSDs from all major NVMe storage vendors. It has also been engineered for use with advanced M.2-based devices such as the Hailo-8™ series M.2 acceleration modules.
