Engineered for reliability, performance, and endurance, this 2.5" U.2 (SFF-8639) NVMe SSD delivers the speed, capacity, and resilience required to handle demanding workloads such as real-time analytics, database operations, virtualization, and high-traffic web services. Built to integrate seamlessly into Cisco and non-Cisco server ecosystems, the SN840 is an excellent choice for organizations seeking to optimize performance per watt, reduce latency, and increase IOPS while maintaining mission-critical data integrity. From boot drives to data tiers, this drive is engineered to accelerate applications, streamline data workflows, and future-proof storage infrastructure across data centers and enterprise environments.

• High-performance NVMe drive for data-center workloads — The Cisco DC SN840 leverages the PCIe NVMe interface to deliver low latency, high throughput, and excellent IOPS for database acceleration, in-memory analytics, virtualized environments, and latency-sensitive applications. Its architecture is optimized to minimize queue depth delays and maximize throughput, allowing business-critical apps to respond faster and scale gracefully as demand grows.
• 1.60 TB capacity in a robust 2.5" U.2 form factor — This drive packs substantial storage density into a compact 2.5" U.2 (SFF-8639) package, enabling easy integration into standard server drive bays and backplanes. The 1.60 TB capacity is well-suited for a wide range of workloads, including operating system hosting, application data stores, and tier-1 storage pools, while preserving valuable rack space in dense data center deployments.
• Enterprise-grade reliability and endurance — Built for continuous operation in data centers, the SN840 emphasizes durability, wear leveling, and error correction to protect data integrity under heavy write workloads. Enterprise-grade features such as power loss protection considerations, ECC, and robust wear management help ensure consistent performance and long service life even under sustained I/O bursts.
• Seamless integration with Cisco server ecosystems — Designed to work within Cisco-based server infrastructures and compatible with other enterprise platforms, the SN840 supports efficient backplane connections, hot-plug capability where available, and smooth firmware updates through standard management pathways. This ensures easier lifecycle management, simpler procurement, and reliable operation across mixed environments.
• Efficient cooling, power efficiency, and data-center optimization — The SN840 is engineered to balance performance with energy efficiency and thermal stability. Lower active power draw per IOPS and effective heat dissipation help maintain cooler server operation, reduce total cost of ownership, and support higher-density rack deployments without compromising performance persistence.

How to install Cisco DC SN840 1.60 TB NVMe SSD

Installing the Cisco DC SN840 NVMe drive is designed to be straightforward in servers that support 2.5" U.2 form factors with SFF-8639 backplanes. Follow these general steps to ensure a safe, reliable installation and optimal performance:

• Power down the server, unplug the power cords, and disconnect any attached peripherals. Ground yourself to prevent electrostatic discharge before handling the drive.
• Identify a compatible 2.5" U.2 drive bay or drive tray in the server chassis. Ensure that the backplane and firmware support NVMe drives in the chosen slot combination.
• If using a drive tray, mount the Cisco DC SN840 into the tray, securing it with screws as required by the chassis design. If the drive is to be installed directly into a hot-plug bay, align the connector and slide the drive into the backplane until it seats firmly.
• Connect the drive to the server’s U.2 backplane or PCIe NVMe interface, ensuring the SFF-8639 connector is fully seated. Confirm that all connections are secure and free of obstruction.
• Power up the server and enter the system BIOS/UEFI or the storage controller’s management interface. Verify that the SN840 is detected as a valid NVMe device. If necessary, perform a firmware update to the latest release and initialize the drive within the operating system or storage controller utility.
• Partition, format, and provision storage as required by your workload. Consider configuring caching, tiering, or storage pools in line with your infrastructure strategy. Finally, monitor the drive’s health using vendor-provided utilities or standard SMART monitoring tools to ensure ongoing reliability.
