Introducing the Dell PowerEdge Compatible 300GB Hot‑Swap SAS Internal Hard Drive – Model 400‑AJRR

The Dell PowerEdge Compatible 300GB Hot‑Swap SAS Internal Hard Drive, model 400-AJRR, is engineered to deliver uncompromised performance and reliability in demanding server and workstation environments. Designed for Dell’s PowerEdge line, this drive seamlessly integrates into a wide range of systems, providing high capacity, rapid data access, and effortless maintenance.

Key Technical Specifications

• Capacity: 300 GB (307,200 MB) – ideal for medium‑size databases, virtual machine images, or high‑density storage arrays.
• Form Factor: 2.5" drive housed in a 3.5" carrier – combines the compactness of a 2.5" disk with the robustness of a 3.5" enclosure for hot‑swap compatibility.
• Rotation Speed: 15,000 RPM – delivers low latency and high throughput for I/O‑intensive workloads.
• Interface: SAS (Serial Attached SCSI) – supports 12 Gb/s data transfer rates, ensuring fast communication with host controllers.
• Hot‑Swap Capability: Yes – allows the drive to be replaced or added without shutting down the system, minimizing downtime.
• Operating Voltage: 5 V / 12 V – compatible with a broad range of power supplies found in Dell servers.

Compatibility Matrix

The 400‑AJRR drive is specifically engineered for Dell’s PowerEdge server family. Below is an exhaustive list of supported models:

• PowerEdge R730, R730XD
• PowerEdge T330, T430, T440, T640
• PowerEdge R230, R330, R430, R530
• PowerVault MD1400

These systems benefit from the drive’s hot‑swap feature, allowing administrators to perform maintenance without interrupting critical services.

Performance Highlights

• Sequential Read: Up to 350 MB/s – ideal for large file transfers and database backups.
• Sequential Write: Up to 300 MB/s – ensures rapid data ingestion for analytics workloads.
• Random IOPS (4K): Approximately 12,000 IOPS – supports high‑transaction applications such as OLTP databases.
• Latency: Sub‑millisecond access times due to the 15,000 RPM spindle speed and SAS interface.

Reliability & Durability

The drive incorporates Dell’s proven SAS controller architecture, featuring error correction codes (ECC) and advanced data integrity checks. Its robust mechanical design includes:

• Shock‑Resistant Enclosure: Protects against accidental drops or vibrations during operation.
• High‑Quality Bearings: Reduce wear, extending the drive’s mean time between failures (MTBF).
• Temperature Management: Operates efficiently within a wide temperature range, suitable for data center racks.

Installation & Maintenance

The 2.5" disk in a 3.5" carrier simplifies deployment:

1. Insert the drive into an available hot‑swap bay. The carrier’s design ensures secure mounting and proper alignment with SAS connectors.
2. Power on the server. The system automatically detects the new storage device without requiring a reboot.
3. Configure in firmware or operating system. Assign logical units, set RAID levels, or integrate into existing storage pools as needed.

Replacing an exhausted drive is equally straightforward: power down the bay (if required), remove the old carrier, insert a new one, and let the server recognize it instantly. This process eliminates downtime for critical applications.

Use Cases & Applications

• Virtualization Platforms: Host virtual machine images with high I/O demands.
• Database Servers: Store transactional data requiring low latency and high throughput.
• Backup & Recovery Solutions: Provide reliable storage for incremental backups and disaster recovery.
• High‑Performance Computing (HPC): Support compute nodes that need fast access to large datasets.
