This 4U black chassis is purpose-built for enterprise-grade expansion, delivering up to 90 drive bays to accommodate a wide range of workloads—from archival backups and media libraries to virtualization and high-performance data processing. Designed for seamless integration into existing server environments, the enclosure supports both 2.5" and 3.5" drives, enabling mixed-drive configurations that optimize capacity, performance, and cost. With non-RAID JBOD operation, administrators gain granular control over each disk while maintaining a simple, scalable path to storage growth. The 946ED-R2KJBOD is the reliable backbone for data-intensive organizations looking to scale their storage footprint without sacrificing manageability or compatibility. Its robust construction, enterprise-minded design, and rack-ready form factor make it an ideal storage expansion solution for data centers, IT departments, and professional server rooms.

• Expands storage with up to 90 drive bays, enabling massive capacity for data centers, media libraries, backups, virtualization workloads, and high-demand enterprise applications. The 90-bay design supports dense HDDs and SSDs, allowing organizations to consolidate storage, manage capacity growth, and tailor performance characteristics for different workloads within a single enclosure. This scalable chassis is ideal for organizations migrating from smaller arrays to centralized disk pools to streamline management and improve total cost of ownership.
• Supports both 2.5" and 3.5" drive forms, offering flexible configuration for HDDs and SSDs and enabling mixed-drive deployments. This versatility helps optimize space, power, and cooling while aligning with existing inventories and future storage strategies, so you can deploy cost-effective drives alongside performance-oriented options without hardware compatibility concerns.
• 4U rack-mountable black chassis designed for enterprise racks with optimized airflow and cable management to help maintain performance and reliability in data center environments. The sturdy enclosure integrates smoothly with standard 19-inch racks, supports clean cable routing, and supports long service lifecycles in demanding IT ecosystems.
• Non-RAID JBOD mode allows independent drive access and streamlined data organization across dozens of disks, empowering administrators to tailor each drive's role—backup, cold storage, or active data—without a single RAID array. This configuration supports flexible data management policies and granular control over individual disks, making it ideal for organizations that need to mix storage tiers and workloads within a single enclosure.
• A versatile, future-proof solution that integrates smoothly with existing servers and storage networks, delivering scalable storage expansion for backups, archiving, virtualization, media workflows, and high-capacity workloads. Its broad drive compatibility and non-RAID design enable scalable expansion without vendor lock-in, while maintaining straightforward integration with mainstream operating systems and storage controllers.

How to Install Supermicro SuperChassis 946ED-R2KJBOD Drive Enclosure

Install this enclosure into a suitable data center environment with attention to power, cooling, and cabling. Use these general steps to integrate it into your storage infrastructure:

• Step 1 — Prepare the rack space: Ensure a clean, secure mounting location in a standard 19" rack. Check that the rack has adequate cooling capacity and power availability to support the 4U enclosure and the drives you plan to install. Confirm that the area around the rack allows for proper airflow to prevent thermal bottlenecks during operation.
• Step 2 — Mount the enclosure: Slide the 946ED-R2KJBOD into an available 4U rack slot and secure it with suitable hardware. Verify that the chassis is level and firmly attached to the rack rails to minimize vibration and ensure stable operation during drive loading and service events.
• Step 3 — Populate drives: Install 2.5" and/or 3.5" drives into the drive trays per your chosen configuration. Follow the enclosure’s drive tray instructions for safe insertion and alignment. Ensure proper seating of each drive and confirm that any required locking mechanisms are engaged to prevent accidental removal during operation.
• Step 4 — Connect data and power: Attach the appropriate data cables from your storage controller or server backplane to the enclosure’s ports. Connect power cables from the power distribution unit or power supplies. Organize cables to maintain airflow and simplify future maintenance, and label connections for easy troubleshooting.
• Step 5 — Power on and configure: Power up the enclosure and perform initial hardware checks. If you plan to use JBOD, configure the drives in non-RAID mode as needed by your storage management strategy. Confirm that each drive is recognized by the host system, then use your operating system’s storage manager to assign drives to pools, folders, or volumes according to your workflow requirements.
