Maximize Your Inference Throughput: Industry-Leading 4-AIPU Compute Density
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.
Why the Rocket 1604L is the Architect's Choice
Unmatched Signal Integrity: Beyond Passive Bifurcation
Most bifurcation cards are "passive," meaning they simply pass the signal through, often carrying electrical noise and interference. The Rocket 1604L is different. It re-clocks and regenerates a fresh, perfect data stream.
Flexible Placement: Whether installed directly on the host CPU slot or via a remote PCIe slot through MCIO cabling, you never have to worry about signal degradation or dropped IOPS.
40% Smaller, 100% Faster
Space is at a premium in compact AI servers. The Rocket 1604L features the shortest board length in its class—over 40% shorter than standard 4-bay M.2 cards. Despite its compact dimensions, it inherits our proven Pro-Class M.2 cooling solution, ensuring your Gen5 devices never thermal throttle, even under 24/7 heavy AI workloads.
Smart Monitoring & Transparent Performance
Server-class architects require visibility. The Rocket 1604L features Smart Firmware that allows you to monitor:
-
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.
-
FRU Module (Field Replacement Unit): stores Vital Product Data (VPD) to ensure seamless replacement while minimizing dowtime for the host server.
Zero Friction Integration
We believe in performance without proprietary headaches. The Rocket 1604L utilizes Native OS Drivers, making it a true Plug-and-Play solution for any modern Linux or Windows server environment. No special software is required to boot or manage your high-speed arrays.

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).
