RocketStor 4243AS: The Entry-Point to NVMe-over-Fabrics

Eliminating Cost Barriers for the Software-Defined Enterprise

The RocketStor 4243AS is HighPoint’s premier Entry-Level NVMe-oF Storage Solution, designed to bring the power of Composable Disaggregated Infrastructure (CDI) to the wider industry. By removing the "Enterprise Tax" and high-budget hurdles associated with complex, over-engineered multi-controller arrays, the RS4243AS makes high-density, Fabric-Attached Block Storage accessible to mid-market enterprises, regional AI pods, and media production houses.

Disaggregated Server Storage - Redefined

Hardware-Accelerated Fabric Offload (WDC RapidFlex™ C2000)

At the heart of the RocketStor 4243AS is the Western Digital RapidFlex™ C2000, a dedicated NVMe-oF Fabric Bridge that transforms the storage enclosure into a high-performance network target.

Near-Zero Target Overhead: Unlike software-defined targets that consume massive CPU cycles to manage network traffic, the C2000 offloads the entire NVMe-oF protocol stack to dedicated silicon. This ensures the RS4243AS delivers consistent 100GbE line-rate performance without taxing the enclosure's management resources.

120-Host Connectivity: Consolidate your storage and serve up to 120 independent host initiators simultaneously. The C2000 manages these virtual controllers in hardware, providing seamless multi-tenant access without protocol bottlenecks.

Transparent Hardware Bridge: The RS4243AS functions as a pure hardware bridge, presenting remote NVMe storage to the network with the same simplicity and speed as locally attached drives.

Unmatched Fabric Flexibility: RoCE v2 or TCP

The RocketStor 4243AS is designed to adapt to your existing infrastructure while providing a clear path for future performance upgrades.

NVMe/TCP (Standard Ethernet): Deploy instantly over your current standard Ethernet network. Experience the benefits of disaggregated storage with zero specialized hardware and maximum compatibility across your existing switch fabric.

NVMe/RoCE v2 (RDMA): For workloads requiring sub-microsecond latency—such as AI/ML training and 8K video editing—leverage RoCE v2 to achieve "wire-speed" performance.

Note: Maximum RDMA performance requires a RoCE-capable SmartNIC on the host initiator.

Green Power & Thermal Reliability: Optimized for Efficiency

The RS4243AS is engineered for the "Green" data center, where every watt of power and every degree of heat matters.

"Lane-per-Drive" Architecture: Utilizing the HighPoint R1528D PCIe Switch, the RS4243AS allocates a dedicated Gen4 x1 lane to each of the 24 NVMe bays. This provides ~45GB/s of internal bandwidth—perfectly saturating the Dual 100GbE network interface (~25GB/s)—without generating the massive heat of an over-provisioned 96-lane configuration.

Reduced Thermal Load: Running 24 lanes instead of 96 significantly lowers the internal temperature of the chassis, protecting your NVMe media from thermal throttling and extending hardware lifespan (MTBF).

Operational Savings: A cooler-running system requires less active cooling, directly reducing your monthly electricity and facility cooling costs.

The "Zero-Constraint" Hardware Bridge

The RS4243AS offers a level of simplicity and open-standard compatibility that software-heavy arrays cannot match.

No Drivers, No Constraints: Natively supported by any OS with an NVMe-oF initiator (Linux, Windows Server 2025, VMware).

RedFish

Open Management: Utilize the integrated ARM-based BMC and native Redfish® API for seamless, out-of-band (OOB) integration into your existing orchestration and monitoring dashboards.
