High-Performance PCIe Gen4 Switch Architecture

R1528D_performance architecture_v1.03_24_4_29.png

HighPoint's High-Performance PCIe Gen4 switching architecture integrates Broadcom’s 48-Channel PEX88048 switch IC to provide x16 lanes of dedicated PCIe Gen4 upstream bandwidth and x4 lanes of dedicated downstream bandwidth to each device channel. The innovative architecture enables the Rocket 152x Series AIC or Adapter to deliver up to 32GB/s of transfer bandwidth, minimize latency, and facilitate consistent, robust I/O throughput.

The Architecture employs a technique known as a “Synthetic Hierarchy” to isolate the host system’s OS from any PCIe topology changes. This enables the AIC or Adapter to directly manage resource allocation to the downstream PCIe channels by facilitating a more efficient interaction between the host CPU and PCIe switch.

Robust, High-Density NVMe Storage Solution with Plug & Play Installation

Rocket 152X series AICs and Adapters are compatiblle with any modern operating system that has native NVMe driver support, and require no unique software or application to function or perform optimally. NVMe media hosted by Rocket 152x Switch AIC and Adapters will be automatically recognized by the OS or SDS (software defined storage) suite as oridnary physical drives, and can be immediately formatted and partitioned as needed.


These features make Rocket 152x AICs and Adapters ideal for professional server and workstation applications that require a flexible, robust and easily managed NVMe storage solution.


Engineered to Enhance the Efficiency & Serviceability of Datacenter & Server Applications

Rocket 152x series NVMe AICs and Adapters incorporate a wide range of features designed to enhance the efficiency of day-to-day operations of datacenter and Edge Server platforms. First and foremost, the adapter has been built to the highest standards of quality and reliability, and is fully compliant with PCIe Card Electromechanical (CEM) specifications. The AICs & Adapters are field replaceable units (FRU); the VPD (vital product data) stored on each product enables customers and service providers to easily procure replacements with the correct firmware/driver combination.

The integrated OOB (out-of-band) management capability is an essential component of professional server infrastructure. MBC & MCTP over PCIe enables an administrator to securely interface with the adapter without the need for internet access. The service is scalable and can be used to administrate multiple servers via Linux command prompts to manage storage in both Pre-OS and OS-level environments.
