Dell J7TNV

Overview

The Dell J7TNV is a PowerEdge PERC HBA330+ SAS RAID controller designed to provide servers with direct access to SATA or SAS storage devices at speeds up to 12 Gb/s. It uses a PCIe x8 Gen 3.0 interface to efficiently transfer data between drives and the host system without the overhead of hardware RAID, making it ideal for setups that rely on software-defined storage solutions. This controller supports up to eight drives through two miniSAS SFF-8643 ports, offering flexibility for expanding local storage in servers used for virtual machines, databases, or backup applications.

Key features

• Direct disk access enabled by preinstalled IT mode firmware, allowing each drive to appear individually to the operating system for software RAID or storage management.
• High-speed PCIe x8 Gen 3.0 interface that ensures fast and efficient data transfer between the server and connected drives.
• Two miniSAS SFF-8643 ports that support up to eight SATA or SAS drives, providing ample connectivity for storage expansion.
• Includes both full-height and low-profile brackets, making it compatible with a wide range of server chassis from standard rackmount to compact desktop towers.
• Simple installation process requiring only standard miniSAS cables, with no need for additional hardware or complex setup.

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.
