Rocket 7528D

PCIe Gen4 x16 to 4-SlimSASx8 NVMe RAID Adapter

The Rocket 7528D 2nd Generation PCIe Gen4 NVMe RAID Adapter was designed for professional applications that require uncompromised Storage Performance with the flexibility of proven RAID technology and the industry's most comprehensive storage health Monitoring & Management suite. It can directly support up to eight 2.5" U.2 or U.3 NVMe SSDs via four SlimSAS SFF-8654 Ports and cable-to-backplane connectivity.

Hosted media can be configured into as many as 4 separate RAID 0, 1 or 10 arrays, including bootable volumes or mixed configurations of single SSDs and arrays. In addition, RocketStor 7528D Adapters are Hot-Plug & Hot-Swap capable; administrators can easily add or remove RAID arrays and individual NVMe SSDs without rebooting the OS or powering down the host platform.

High-Performance Gen4 Switching Architecture

48 Lanes of Dedicated PCIe Gen4 Bandwidth

HighPoint's High-Performance PCIe Gen4 switching architecture integrates Broadcom’s 48-Channel PEX88048 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 7528D 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 Rocket 7528D to directly manage resource allocation to the downstream PCIe channels and provide true Hot-Swap /Hot-Plug capability by facilitating a more efficient interaction between the host CPU and PCIe switch.

True NVMe Hot-Plug & Hot-Swap Capability

R7628A_performance architecture_v1.02_24_4_17.png

The Rocket 7528D provides true NVMe SSD Hot-Swap and Hot-Plug capability; an essential feature for any professional server and datacenter platform. Administrators can safely add or remove individual SSDs or RAID arrays without rebooting the OS or powering down the host system.

The Rocket 7528D utilizes Synthetic Hierarchy to isolate the host operating system from any PCIe topology changes (physical changes) and any events associated with the sudden addition or removal of an NVMe device.

The adapter accomplishes this by creating virtual “placeholders” to reserve dedicated resources for each of the eight NVMe downstream ports whenever the system is booted. This technique ensures these channels remain active at all times. Adding an SSD will temporarily replace the corresponding placeholder. Likewise, removing an SSD will reactivate the corresponding placeholder.

PCIe Gen4 Hyper-Cooling Solution

The Rocket 7528D's Low-Noise Hyper-Cooling solution combines the industry's most advanced PCIe Gen4 hardware cooling system with a suite of pro-active monitoring and management tools designed to keep temperatures in check under the most grueling working conditions.

R7628A_performance architecture_v1.02_24_4_17.png

The Rocket 7528D's passive, fan-less cooling system pairs copper piping with an aluminum heat exchanger for maximum thermal efficiency & durability. This Zero-Maintenance design is ideal Server & Data Center applications.

SHI (Storage Health Inspector): Administrators can instantly asses the operating status of hosted NVMe media via S.M.A.R.T. (self-monitoring and reporting technology), can customize temperature thresholds for each NVMe SSD, manually adjust fan speed to best accommodate the target application, and configure email notification services to monitor storage from afar.

Comprehensive Storage Health Monitoring, Management & Analysis Suite

The Rocket 7528D is equipped with HighPoint’s intuitive yet comprehensive monitoring, management and analysis suite, which enables administrators to easily configure and maintain the platform’s NVMe storage ecosystem with a few simple clicks and commands. SSDs and RAID 0, 1 and 10 arrays created and managed using these interfaces will be recognized as single, physical disks by the host platform, and can be used to install a bootable OS.

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.

OOB Management

The Rocket 7528D provides OOB (out-of-band) management capability; an essential component of datacenter server infrastructure. BMC and MCTP over PCIe enables administrators and service technicians to securely interface with the NVMe AIC 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.
