Fujitsu PRAID EP420i Network Server

Fujitsu PRAID EP420i Network Server

The Fujitsu PRAID EP420i is a high‑performance, enterprise‑grade RAID controller designed to deliver reliable data protection and rapid throughput for demanding storage environments. Built around the LSI MegaRAID SAS3108 chipset, it supports both SAS and SATA interfaces, enabling flexible deployment across a wide range of server platforms.

Key Design Features

• PCIe 3.0 x8 Host Interface: Provides a robust 12 Gb/s data path, ensuring low latency and high bandwidth for modern workloads.
• Full‑Height (Low‑Profile) Form Factor: Fits seamlessly into standard server chassis while maintaining a compact footprint of 53 mm depth and 87 mm width.
• Eight Independent Channels: Each channel supports up to 8 SATA 6 Gb/s or SAS 12 Gb/s drives, allowing for extensive scalability.
• Advanced RAID Levels: Supports RAID 0, 1, 5, 6, 10, 50, and 60, giving administrators granular control over performance versus redundancy trade‑offs.
• 2 GB Onboard Cache: Enhances write performance and protects against data loss during power interruptions.
• S.M.A.R.T. Monitoring: Continuous health checks for all connected drives, enabling proactive maintenance.

Connectivity & Power Options

The controller is powered via a standard USB Type‑C connection, drawing up to 5 V from the host system. This design eliminates the need for additional power supplies and simplifies installation. The included USB cable supports data rates of 480 Mbps (USB 2.0) and 5000 Mbps (USB 3.0/3.1 Gen 1), ensuring versatile connectivity for both legacy and modern systems.

Supported Operating Systems

The EP420i is fully compatible with a broad spectrum of Windows operating systems, ranging from Windows XP to the latest Windows 10 Enterprise editions. Its drivers are engineered for stability across both 32‑bit and 64‑bit architectures.

Performance Metrics

• Maximum Data Transfer Rate: 12 Gb/s per channel, translating to a theoretical aggregate throughput of up to 96 Gb/s across all eight channels.
• Mean Time Between Failures (MTBF): 1,500,000 hours, underscoring the controller’s reliability in mission‑critical deployments.
• Power Consumption: Only 2.5 W under typical load, making it an energy‑efficient choice for data centers.

Physical Specifications

Drive Compatibility

The EP420i accommodates both traditional HDDs and SSDs. Typical configurations include:

• HDD: 2.5" drives up to 1 TB, spinning at 5400 RPM.
• SSD: 256 GB solid‑state drives in the same 2.5" form factor.

Installation & Management

Upon installation, the controller is recognized by standard operating system utilities and can be managed via Fujitsu’s dedicated management software or third‑party RAID configuration tools. The included user guide provides step‑by‑step instructions for initializing arrays, configuring RAID levels, and monitoring drive health.

Use Cases

• Enterprise File Servers: Leverage RAID 10 or 50 for high throughput and fault tolerance.
• Virtualization Hosts: Use RAID 5/6 to balance capacity with redundancy, ideal for VM storage pools.
Backup & Recovery Solutions: Employ RAID 60 for large‑scale backup arrays requiring both performance and data protection.

Conclusion

The Fujitsu PRAID EP420i Network Server combines robust hardware, versatile RAID options, and low power consumption to meet the demands of modern enterprise storage environments. Its seamless integration with a wide range of operating systems and server platforms makes it an excellent choice for organizations seeking reliable, high‑performance data protection.
