iStarUSA D-300 3U Rackmount Chassis — Industrial RAID-Ready Storage Solution

The iStarUSA D-300 is a purpose-built 3U industrial rackmount chassis engineered for demanding storage deployments in data centers, labs, and industrial environments. This chassis blends rugged durability with modular expandability, delivering a scalable foundation for RAID-ready storage systems, hot-swappable drives, and flexible backplane configurations. With its emphasis on serviceability, airflow, and compatibility with a wide range of add-on cards, the D-300 is designed to simplify complex storage architectures while maintaining reliability and ease of maintenance in high-demand operating environments.

• Flexible drive configurations and RAID support: The D-300 is designed to accommodate a variety of storage arrangements through optional BPU Series hot-swappable storage modules. It supports essential RAID configurations including 1, 0, 0+1, and JBOD, giving you the choice to implement fault tolerance, performance, or straightforward JBOD expansion according to your workload. Whether you’re deploying fault-tolerant servers in critical applications or building dense storage arrays for archival data, the D-300 offers the flexibility to tailor storage topology to your needs. The ability to mix drive types, capacity tiers, and hot-swappable bays simplifies maintenance windows and reduces downtime during upgrades or replacements.
• Backplane with expansive add-on card support: A defining feature of the D-300 is its backplane designed to support up to seven full-length add-on cards. This expansive backplane enables you to deploy a variety of controllers, storage adapters, or expansion cards without sacrificing bay density. The modular design makes it feasible to upgrade I/O capabilities, improve bandwidth, or adapt to evolving networking and storage requirements, all within a compact 3U footprint. When you pair the D-300 with compatible SAS/SATA controllers and high-speed expanders, you unlock scalable performance for intensive workloads while preserving a clean, organized rack layout.
• Maximum drive capacity and expansion options: The chassis is engineered to handle up to a total of six HDD storage bays, with configurations that suit small-to-medium enterprise workloads or industrial data collection systems. The practical drive-count provided by the D-300 enables a balance between capacity, performance, and cooling, making it ideal for RAID sets, JBOD expansions, or hybrid configurations that combine HDDs for bulk storage with SSDs for caching or high-IO demands. The design prioritizes straightforward drive installation and maintenance, helping IT teams deploy storage quickly and confidently.
• Weight-conscious aluminum body option for easier deployment: An optional Aluminum Body reduces overall chassis weight, making the D-300 more manageable during installation, relocation, and service procedures. In environments where rack space, forklift access, or frequent maintenance is a factor, the lighter aluminum variant can improve ergonomics and reduce the risk of damage during handling. The aluminum option also contributes to a cooler, more efficient thermal profile by aiding airflow around the chassis, which can be beneficial in data centers with mixed workloads or constrained cooling resources.
• Rugged construction and enterprise-grade reliability: Built for industrial environments, the D-300 emphasizes sturdy construction, consistent airflow, and reliable operation. Its 3U form factor fits standard 19-inch racks, enabling seamless integration into existing infrastructure. The chassis is designed to support hot-swapping, modular expansion, and long service intervals, supporting uptime and predictable maintenance cycles in environments that require steady performance and robust protection for valuable storage assets. For teams deploying data logging, sensor networks, or edge-to-core storage architectures, the D-300 provides a dependable platform that scales with evolving storage demands.

How to install iStarUSA D-300 Chassis

• Prepare your workspace and confirm you have a compatible 19-inch rack with sufficient clearance for a 3U chassis, including space for cable management and airflow.
• Power down and unplug any existing equipment, then mount the D-300 into the rack using the included rails or compatible mounting hardware. Ensure the chassis is level and securely fastened to prevent vibrations that could affect drive operation.
• Install the Aluminum Body option if desired to reduce weight. Confirm all screws are tightened to manufacturer guidelines to maintain structural integrity and proper grounding.
• Attach the backplane and installed add-on cards. Connect the appropriate SAS/SATA controllers or expansion cards to the backplane and verify that all connectors are firmly seated. Route cables to minimize obstruction to airflow and to prevent accidental disconnections during service.
• Install the drives into the six HDD bays according to your RAID plan. If using hot-swappable BPU bays, verify the hot-swap trays are properly seated and the drive trays engage with the backplane ports securely.
• Connect power and data cables to the backplane and control interfaces. Power on the system and enter the RAID or server BIOS or controller configuration utility to configure your designated array (e.g., 1, 0, 0+1, JBOD) and to initialize drives if required.
• Perform a basic health check by monitoring drive detection, controller status, and temperature readings. Ensure fans are operating within spec and that there are no warning indicators indicating drive faults or connectivity issues.
• Document the final configuration, including drive order, RAID level, and controller settings. This will simplify future maintenance, upgrades, and troubleshooting.

Frequently asked questions

• What is the key purpose of the iStarUSA D-300? The D-300 is a versatile 3U rackmount chassis designed to deliver scalable, RAID-ready storage for industrial and data-center deployments. It emphasizes modular expandability, hot-swappable storage options, and a backplane capable of accommodating multiple add-on cards, making it suitable for high-availability storage environments and enterprise-grade workloads.
• How many drives can I install? The chassis supports up to six HDDs in its drive bays, with configurations that vary depending on the selected BPU option and RAID strategy. This density makes it well-suited for moderate-scale storage deployments where capacity planning and performance tuning are essential.
• Does the D-300 support hot-swappable drives? Yes. With the optional BPU Series, storage drives can be hot-swapped, enabling maintenance or upgrades without powering down the entire system. This feature is particularly valuable for minimizing downtime in production environments and for quickly replacing failed drives in critical deployments.
