High-Density Design

The Lenovo ThinkSystem D4390 is enterprise-class storage that delivers massive scalability, allowing you to easily expand as your data needs grow. The high-density design is 34% more dense than the previous generation enclosure (Lenovo D3284), allowing for more drives in less physical space.

The Lenovo ThinkSystem D4390 is ideal for HPC simulations, object storage, Tier 3 cloud data providers, video streaming, global file sharing, big data and analytics, video surveillance, private and hybrid clouds, and backup and archiving.

Optimized Storage

The Lenovo ThinkSystem D4390 is a single, flexible expansion platform that utilizes existing infrastructure, providing a lower TCO and immediate savings on traditional capital costs.

High-capacity 3.5" NL-SAS drives offer up to 1620TB of “cold” or archive storage in only 4U, and up to 8.1PB in 20U, using daisy-chained enclosures.

SSDs (up to 48TB in 20U) provide the throughput necessary for the most I/O intensive jobs. With up to 12 drives per enclosure and 24 per daisy-chain, there is plenty of room for multitiered drive types.

Enterprise Simplicity and Reliability

Seamless integration with Lenovo servers makes deployment easy and supports mixing and matching of SAS, NL-SAS, and SSD drives for high-performance, high-capacity, or a combination of the two.

The Lenovo ThinkSystem D4390 is also key component within the Lenovo Distributed Storage Solution (DSS-G) for IBM Spectrum Scale.

Hot-swap redundant components, including dual Environmental Service Module (ESMs) and 5V DC-DC modules, quad 1200W 80 Plus Titanium power supplies, in addition to five fans, provide the high availability needed for enterprise environments.
