Lenovo 4XB7A62771 – 16TB 7.2K RPM 3.5″ NL-SAS LFF

The Lenovo Storage 16TB 7.2K RPM 3.5″ NL-SAS LFF (Large Form Factor) Hard Drive is a high-capacity hard disk storage drive optimized for mass storage environments and workloads that require a balance between performance and cost. With a rotational speed of 7,200 RPM (revolutions per minute), this HDD offers consistent data transfer rates, making it suitable for applications such as backups, data archiving, big data analytics, and hybrid cloud storage.

This particular model, with part number Lenovo 4XB7A62771, was developed by Lenovo for use in the ThinkSystem Storage D1212 drive expansion enclosure, compatible with machine types 4587 and 4588. It comes complete with the carrier (bracket) required for installation, plus front LEDs that allow real-time monitoring of the drive’s status. When inserted into the dual-path direct dock SAS interface, the disk ensures redundancy and high availability, minimizing downtime risks in critical environments.

Imagine a busy data center where terabytes of data needs to be accessed quickly without compromising integrity. This NL-SAS (Nearline SAS) HDD is perfect for this, as it combines the high-speed SAS interface with the economics of a nearline design, ideal for secondary or long-term storage. Unlike more expensive SSDs, it prioritizes massive capacity over extreme speed, but still delivers solid performance for sequential reads and writes. For example, in an enterprise backup scenario, you can store years of historical data without worrying about insufficient space.

At DC Parts, we test and validate products like this to ensure they meet the highest standards. If you already use Lenovo ThinkSystem enclosures, this drive integrates effortlessly, expanding your storage capacity in a scalable way. Let’s now move on to the technical specifications for a deeper dive.

Technical Specifications

Here’s a detailed look at the specifications of this hard drive, compiled to make it easier to compare and make a purchase decision. We use official Lenovo data and our expertise to ensure accuracy.

• Storage Capacity: 16TB (Terabytes) – This allows you to store huge volumes of data, such as databases, media files, server logs, or complete system backups. For context, 16TB is equivalent to about 3,200 HD movies or millions of office documents.

• Rotational Speed: 7,200 RPM – Offers an ideal balance between performance and power consumption. In real-world testing, this results in sustained throughput rates of up to 250 MB/s for sequential reads, depending on the environment.

• Form Factor and Size: 3.5 inches (LFF – Large Form Factor) – Designed for larger drive slots in enterprise enclosures, making it easy to install in standard 19-inch racks.

• Interface: NL-SAS (Nearline Serial Attached SCSI) – Supports speeds up to 12Gb/s, with backward compatibility for SAS 6Gb/s. Dual-path design ensures redundancy, allowing the disk to continue operating even if one path fails.

• Part Number: Lenovo 4XB7A62771 – Official Lenovo code for identification and compatibility.

• Features Included:

  • Carrier – Facilitates hot-swappable insertion and removal, without the need to shut down the system.
  • Front LEDs – Status indicators (green for normal, amber for alert, red for failure), allowing for quick visual monitoring in crowded data centers.
  • SAS Direct Dock Support – Direct integration with the enclosure, eliminating extra cables and reducing points of failure.

• Power Consumption: Approximately 8-10W in operation, with idle mode around 6W, making it efficient for multi-drive environments.

• MTBF (Mean Time Between Failures): Over 2 million hours, based on industry standards, ensuring durability in continuous use 24/7.

• Operating Temperature: 5°C to 60°C, with vibration and shock support for industrial environments.

Compatibility and Installation

This hard drive is specifically compatible with the Lenovo ThinkSystem Storage D1212 expansion enclosure on machine models 4587 and 4588. It integrates seamlessly with ThinkSystem systems, including SR and ST series servers, as long as the enclosure is configured for SAS.

Steps for Installation (Simplified Guide):

1. Power off the enclosure if necessary (although hot-swap support in RAID configurations).
2. Insert the drive into the available slot using the included carrier.
3. Connect via dual path SAS interface – LEDs will illuminate to confirm status.
4. Configure in Lenovo management software (such as XClarity) for RAID or JBOD.
5. Test the unit with diagnostic tools to ensure integrity.

Real-world examples: In an e-commerce company’s data center, this HDD can be used to expand transaction log storage by integrating with RAID 6 arrays for redundancy. If your setup is different, check compatibility with our team – we avoid common problems such as firmware mismatches.

Warning: Always refer to the enclosure manual for accurate installation. DC Parts offers technical support for complex installations.

Additional Features and Benefits

In addition to the basic specs, this HDD brings features that elevate its usefulness:

• Status Monitoring via LEDs: Facilitates proactive maintenance, reducing downtime. For example, in a Network Operations Center (NOC), operators can identify faults from a distance.
• Dual Path Design: Built-in redundancy, ideal for high-availability environments such as banking or healthcare, where data loss is unacceptable.
• NL-SAS Technology: Combines the best of SAS (performance) and SATA (cost), with optional encryption for GDPR or HIPAA compliance.
• Energy Efficiency: Low power helps in sustainable data centers, reducing electricity costs in setups with dozens of drives.

Advantages:

• High Capacity: Store more data without multiplying drives, saving rack space.
• Cost-Effective: Cheaper per TB than SSDs, perfect for cold storage or archiving.
• Durability: Designed for 24/7 operation, with a low failure rate.
• Scalability: Add multiple drives to the D1212 for petabytes of storage.

Cons:

• Limited Speed: Not ideal for IOPS-intensive workloads (use SSDs for this).
• Noise and Heat: Spinning HDDs generate more vibration than SSDs, although this model is optimized.
• Compatibility Dependency: Limited to specific Lenovo enclosures.

In summary, the benefits outweigh the drawbacks for most enterprise uses, especially in big data or backup scenarios.

Applications and Use Cases

This HDD shines in a variety of scenarios:

• Data Centers and Cloud: Expand storage for VMs or containers on platforms such as VMware or Hyper-V.
• Backups and Archiving: Store historical data in compliance with regulations, such as in financial industries.
• Big Data and Analytics: Support tools like Hadoop or Spark, where capability is king.
• Real-world example: A digital media company uses drives like this to store video libraries, accessing data sequentially without bottlenecks.
