Rocket 1608A

PCIe 5.0 x16 to 8-M.2x4 NVMe Switch AIC

HighPoint Rocket 1600 series switch AICs/adapters provide enterprise-class NVMe storage connectivity and administrative capability and are suitable for use with a wide range of industry-standard x86 server and workstation platforms. These versatile, high-performance AICs and Adapters are equipped with our revolutionary PCIe Gen5 Switch Architecture and are capable of directly supporting up to eight NVMe SSDs, or as many as 32 NVMe devices via backplane connectivity.
NVMe media hosted by Rocket 1600 Switch AIC/Adapters will be automatically recognized by any OS platform with Native NVMe driver support. This makes them an ideal for businesses and organizations seeking to enhance critical workflows with flexible, robust and easily managed Gen5 NVMe storage performance.

The Rocket 1608A 8-Channel NVMe Switch AIC is an ultra-compact high-density, M.2 NVMe storage connectivity solution capable of delivering up to 64GB/s of transfer bandwidth industry-standard x86 workstation and server platforms. Each AIC can directly host up to eight 2280 form factor M.2 SSDs, which removes the need for internal drive bays and cabling accessories. The Rocket 1608A AICs intelligent PCIe Gen5 cooling solution employs a full-Length Aluminum Heatsink with copper SSD contacts and a powerful low-decibel cooling to ensure hosted M.2 SSDs always operate within their recommended temperature threshold to maximize lifespan and transfer performance.

High-Performance Gen5 Switching Architecture

48 Lanes of Dedicated PCIe Gen5 Bandwidth

HighPoint's high-performance PCIe Gen5 switching architecture integrates Broadcom’s 48-Channel PEX89048 switch IC to provide x16 lanes of dedicated PCIe Gen5 upstream bandwidth and x4 lanes of dedicated downstream bandwidth to each device channel. The innovative architecture enables the Rocket 1608A to deliver up to 64GB/s of transfer bandwidth, minimize latency, and facilitate consistent, robust I/O throughput.

The Architecture employs a technique known as a “Synthetic Hierarchy” to directly manage resource allocation to the downstream PCIe channels by facilitating a more efficient interaction between the host CPU and PCIe switch.

Advanced PCIe Gen5 Cooling Solution

R7628A_performance architecture_v1.02_24_4_17.png

Rocket 1608A AICs intelligent PCIe Gen5 cooling solution employs a full-Length Aluminum Heatsink with copper SSD contacts, two layers of thermal padding and a powerful low-decibel cooling to ensure hosted M.2 media always operate within their recommended temperature threshold to maximize lifespan and transfer performance. 

Intelligent Self-Diagnostic LEDs

HighPoint PCIe Gen5 AICs and Adapters feature Built-In Early Warning LED Indicators. Simple color coding and flash-patterns enable administrators to instantly asses the operational status and condition of hosted SSDs and RAID arrays, the strength of the PCIe connection, and temperature of the PCIe switch hardware.
