Lenovo 7N47A00117

Overview

The Lenovo 7N47A00117 is a 400 GB internal solid state drive designed for 2.5 inch hot swap bays commonly found in Lenovo ThinkSystem servers. It features a 12 Gb/s SAS interface that integrates seamlessly with existing server backplanes, enabling faster storage performance without requiring changes to the server architecture. With data transfer speeds up to 12 Gb/s and the ability to handle 197,000 random read IOPS and 50,000 random write IOPS, this drive accelerates demanding workloads such as database queries, virtual machine migrations, and analytics tasks.

Built for continuous data center operation, the drive maintains a power draw of just 9 watts during active use, helping to manage heat output effectively. Its reliability is underscored by a mean time between failures (MTBF) of 2 million hours, supporting long service intervals and predictable maintenance. Compatible with Lenovo ThinkSystem models including SR530, SR650, SR850, and SN550, it offers flexible deployment options as primary storage, RAID expansion, or a ready spare.

Compatibility and deployment

This SSD is compatible with a range of Lenovo ThinkSystem servers, including the SR530, SR650, SR850, and SN550 models. It fits well in environments that require reliable, high-throughput storage solutions such as virtualization hosts, transactional databases, and data analytics platforms. IT teams can deploy it as a primary storage device, expand existing RAID arrays, or keep it as a hot spare to ensure minimal downtime.

Performance and reliability

Leveraging the PM1635a platform, the drive delivers consistent performance with high random read and write IOPS, which translates into faster data access and improved responsiveness for critical applications. Its low power draw helps maintain manageable operating temperatures, contributing to the drive’s longevity and stable operation in demanding data center conditions. The 2 million hour MTBF rating provides confidence in its durability and reduces the frequency of maintenance interventions.

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.
