QNAP CAB-PCIE10M-8644-8X

Overview

The QNAP CAB-PCIE10M-8644-8X is a 3.3-foot PCIe 3.0 x8 cable designed to connect a QNAP NAS directly to a JBOD expansion enclosure. It features two 36-pin SFF-8644 connectors that create an external SAS pathway capable of transferring data at speeds up to 64 Gb/s when paired with a TL-Rx00PES-RP chassis or a QXP-3X8PES adapter card. On other supported QNAP models, it operates at up to 32 Gb/s, providing sufficient bandwidth for tasks like backups, media editing, and virtual machine storage.

This cable’s length is optimized for rack environments, allowing connections between adjacent devices without excess slack that could obstruct airflow. Its locking latches ensure a secure connection, maintaining stability even during equipment maintenance or movement.

Key features

• 3.3-foot length designed to minimize cable clutter and improve airflow in rack setups
• Dual 36-pin SFF-8644 connectors with locking latches for a reliable and secure connection
• Supports up to 64 Gb/s data throughput with specific QNAP chassis and adapter cards
• Backward compatibility at up to 32 Gb/s with other QNAP NAS models
• Enables easy expansion of storage capacity without opening the NAS chassis
• Qualified by QNAP to ensure tested performance and compatibility within their expansion ecosystem
• Simple plug-and-play setup that integrates seamlessly with QTS or QuTS hero operating systems

Key specs

• Interface: PCIe 3.0 x8
• Length: 3.3 feet (1 meter)
• Connector type: 36-pin SFF-8644 on both ends
• Maximum throughput: 64 Gb/s with TL-Rx00PES-RP or QXP-3X8PES
• Backward throughput: up to 32 Gb/s on other compatible QNAP models

Connectivity and compatibility

This cable is specifically designed to link QNAP NAS devices to JBOD expansion enclosures, supporting high-speed SAS connections. It works best with QNAP’s TL-Rx00PES-RP chassis and QXP-3X8PES adapter cards to achieve maximum data transfer rates. For other QNAP NAS models, it still provides robust performance at half the maximum speed, ensuring broad compatibility within QNAP’s storage solutions.

The secure locking mechanism on the SFF-8644 connectors prevents accidental disconnections, which is crucial in environments where equipment may be moved or serviced regularly.

Ideal uses and environments

This cable is well suited for IT professionals managing rack-mounted storage systems who need to expand capacity without disrupting existing setups. It fits naturally in data centers, media production studios, and virtualized environments where fast, reliable access to large volumes of data is essential. Video editors can benefit from keeping high-resolution footage on a dedicated expansion shelf, while system administrators can add drive bays without opening the NAS chassis, reducing downtime and maintenance complexity.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
