LRSV9310-2IR uses the Marvell 88NR2241, a dual-port RAID controller designed specifically for NVMe SSDs. It integrates a PCIe 3.0 x8 host interface and two NVMe ports, supporting hardware RAID operations without consuming host CPU resources for data striping and mirroring.
Technical Advantages
· Hardware RAID Acceleration: Dedicated RAID engine, independent of host CPU, freeing up system computing resources.
· Low-Latency Design: Optimized data path reduces I/O delay and improves responsiveness.
· High Compatibility: Supports a full range of M.2 NVMe SSDs (consumer and enterprise-grade).
· Stability & Reliability: Built on Marvell’s storage expertise for long-term stable operation.
LRSV9310-2IR supports three configurable modes to match application needs:
RAID 0 stripes data across two SSDs for parallel access, nearly doubling sequential read/write performance.Suitable for: temporary cache, video recording buffers, real-time data analytics, and reconstructible data.
RAID 1 mirrors data to two SSDs simultaneously. If one drive fails, the other takes over instantly with zero data loss or downtime.Suitable for: critical production data, quality inspection logs, configuration files, and important records.
In JBOD (Just a Bunch Of Disks) mode, two SSDs operate independently and are recognized separately by the OS.Suitable for: data archiving, log storage, multimedia libraries, and high-capacity needs.
LRSV9310-2IR supports mainstream industrial and commercial operating systems:
Chinese OS: Galaxy Kylin V10, NeoKylin 7.6, OpenKylin 0.7.5, Deepin 15.11/20/20.6/20.9, Fangde Desktop/Server OS, UOS 20, New Start OS 5.0.5, YMOSGlobal OS: Windows 10/11, Windows Server 2016/2019/2022, RHEL/CentOS 7.6/7.9/8.2/9.0, Ubuntu 18.04.5/20.04.1/22.04.2, SUSE 15 SP2, VMware ESXi 6.7/7.0/8.0
This broad compatibility enables seamless integration into industrial automation systems, from domestic China IT projects to traditional Windows/Linux environments.
Engineered for harsh industrial environments:
· Wide Temperature Range: 5°C to 50°C for reliable operation in most factory settings.
· Low Power Consumption: Min 2.988W, max 11.904W, reducing thermal load.
· Compact Size: Low-profile, half-length form factor fits space-constrained IPC chassis.
· Flexible Bracket: Full-height preinstalled; low-profile included for multiple chassis types.
In precision manufacturing (electronics, semiconductors, auto parts), vision systems generate massive high-resolution images. RAID 0 delivers double write bandwidth for real-time recording; RAID 1 protects inspection logs for traceability.
Sensor data, equipment status, and process parameters require local storage and real-time analysis. LRSV9310-2IR provides reliable local storage for fast I/O, supporting on-site AI inference and real-time decision-making.
Industrial surveillance requires 24/7 continuous recording. RAID 1 ensures video data safety; single-drive failure does not lose critical footage.
Selection & Deployment Guidelines
· Motherboard Slot: Confirm PCIe 3.0 x8 / x16 availability and physical compatibility.
· SSD Selection: Choose capacity and endurance based on usage; wide-temperature SSDs recommended for industry.
· RAID Planning: Select mode based on data criticality and performance needs.
· Thermal Design: Ensure sufficient chassis airflow; use SSDs with heatsinks if needed.
· Driver Preparation: Some OS require Marvell RAID drivers; prepare in advance.
With the Marvell 88NR2241 controller, flexible RAID configuration, wide OS compatibility, and industrial-grade reliability, LRSV9310-2IR offers a cost-effective storage expansion solution for industrial PCs. It satisfies performance, capacity, and reliability demands in machine vision, IIoT, and edge computing.
For enterprises upgrading industrial automation or deploying edge computing, LRSV9310-2IR is a strong candidate for storage expansion shortlists.
