Back to the Office
Microsemi SmartRAID 31548i16e is a high‑performance PCI Express x8 3.0 RAID controller designed for enterprise storage environments that demand reliability, scalability, and advanced data protection.
Key Design Features
The controller incorporates the SmartROC 3100 chipset, a purpose‑built solution engineered to deliver exceptional throughput while minimizing latency. Its 12 Gbit/s PCIe interface ensures that data can flow rapidly between host systems and storage arrays, making it ideal for high‑density servers and blade platforms.
Form Factor & Physical Characteristics
Built in a compact MD2 form factor, the card measures 6.57 inches (167 mm) wide and 2.52 inches (64 mm) high, allowing it to fit into half‑height (low‑profile) server chassis without compromising airflow or space. The compact design does not sacrifice performance; the controller’s internal architecture is optimized for dense deployment.
Internal Memory & Cache Architecture
The SmartRAID 31548i16e boasts a generous 4 GB DDR4 cache, clocked at 2100 MHz. This high‑speed memory buffer plays a critical role in buffering I/O operations, reducing write amplification on SSDs, and providing fast data access for read‑intensive workloads. The large cache also supports advanced features such as RAID level migration, enabling administrators to reconfigure RAID levels without downtime.
Port Configuration & Connectivity
Equipped with 8 internal mini‑SAS HD ports, the controller can connect up to 24 drives (both SAS and SATA III) in a single chassis. The mini‑SAS HD interface offers robust signal integrity, low power consumption, and support for hot‑plug operations, ensuring that drive replacements or additions do not interrupt service.
Supported RAID Levels
The controller supports a comprehensive set of RAID levels, including:
- RAID 0 – Striping for maximum performance.
- RAID 1 – Mirroring for data redundancy.
- RAID 1 ADM – Advanced mirroring with automatic defect management.
- RAID 5 – Block‑level striping with distributed parity.
- RAID 6 – Dual parity for enhanced fault tolerance.
- RAID 10 – Striping of mirrored sets.
- RAID 50 – Nested RAID 5 and 0 for scalability.
- RAID 60 – Nested RAID 6 and 0 for maximum data protection.
Operating System Compatibility
The SmartRAID 31548i16e is fully compatible with a wide range of operating systems, ensuring seamless integration into existing infrastructure:
- Windows Server 2008 x64, 2012 x64, and 2016 x64.
- Windows 10, 7 x64, and 8 x64.
- Linux distributions – The controller is supported on major Linux kernels, providing robust driver support for enterprise deployments.
Advanced Features & Reliability Enhancements
The controller incorporates several features that enhance data integrity and system resilience:
- SMART Support – Continuous monitoring of drive health metrics to preemptively detect failures.
- SSD Support – Optimized firmware for solid‑state drives, including wear leveling and TRIM support.
- Hot‑Plug Capability – Drives can be added or removed without shutting down the system, minimizing downtime.
- RAID Level Migration – Allows dynamic reconfiguration of RAID levels while preserving data integrity.
- Mean Time Between Failures (MTBF) – Rated at 2,000,000 hours, reflecting the controller’s robust design and high‑quality components.
Compliance & Certifications
The SmartRAID 31548i16e meets a broad spectrum of industry certifications, underscoring its suitability for mission‑critical environments:
- RoHS, CE, FCC, UL, C‑tick, VCCI, KCC, and CNS.
Use Cases & Deployment Scenarios
This controller is engineered for:
- Enterprise Storage Arrays – High‑density configurations requiring robust data protection.
- Virtualization Platforms – Delivering low latency and high throughput to virtual machines.
- Backup & Disaster Recovery Solutions – Leveraging RAID 6 or 60 for maximum fault tolerance.
- High‑Performance Computing (HPC) – Supporting large datasets with fast I/O paths.
Conclusion
The Microsemi SmartRAID 31548i16e combines a powerful SmartROC 3100 chipset, extensive cache, and versatile port configuration to deliver reliable, high‑throughput storage solutions. Its broad operating system support, advanced RAID capabilities, and rigorous compliance certifications make it an ideal choice for data centers that demand uncompromised performance and resilience.
