Overcoming Tradeoffs

QLC (quad-level cell) flash drives offer greater storage capacity and density for better cost-efficiency than TLC (triple-level cell) flash drives - and even HDDs.

Higher capacities mean that QLC flash drives store more data per memory cell and also feature a greater number of charge levels. These factors ultimately decrease the number of P/E (program/erase) cycles – or write cycles – they can support compared to TLC drives. Historically, this has meant that QLC drives have a shorter lifespan than their TLC counterparts.

EXAScaler

DDN EXAScaler further mitigates this issue by writing small IO-intensive metadata to TLC and sending larger file writes directly to QLC.

This architectural design offers three advantages:

01
Diminishes concerns around drive endurance by reducing write amplification
02
Unlocks performance by directly writing to and reading from QLC
03
Simplifies the architecture by avoiding an expensive tier (such as storage class memory) to cache data before writing to QLC
Needs Title Here
Start with a single self-contained 2U QLC solution - and zero additional components. That means no backend network switches and cabling, no tiering or any of the complexity associated with other QLC-based solutions.
Want to Scale Up Fast and Efficicently?
Just add enclosures and grow QLC capacity to multiple petabytes in a single appliance without rearchitecting anything.
Need Scaling Capacity or Performance?
Just plug additional appliances directly into your network to add space and horsepower to your file system. Scale to hundreds of petabytes without performance degradation.

OVERCOME PERFORMANCE SHORTCOMINGS

Simply Adding Flash is Not Enough to Meet Your AI Workload Demands

QLC-based distributed storage systems can provide a lower-cost, high-capacity solution, but they are inadequate for high-performance environments.

Some solutions use storage class memory as a first step for writes, then proceed to tier the data via a complex backend fabric with unwieldy switching and cabling. But even with additional storage class memory, QLC-based systems still can't meet the IOPs, write throughput and latency requirements for today's AI, machine learning and real-time applications.

OVERCOME PERFORMANCE SHORTCOMINGS

DDN Breaks Down Performance Barriers

DDN eliminates the shortcomings of distributed storage with a more efficient design that uniquely combines the power of DDN's parallel file system with direct writes to QLC flash.

DDN's client-side compression also improves full stack efficiency and performance by uniquely trading network traffic for additional CPU cycles. Because less data is moved over the wire, the reduced network traffic reduces contention and increases application performance.

Performance at Scale for AI & Data Center Use Cases

Yes, AI is top of mind for most organizations, but additional applications and use cases are also driving the requirement for efficient, dependable performance that readily scales.

DDN's QLC and hybrid systems are purpose-built to deliver workload-specific performance optimization. You get twice the capacity and performance per watt to accommodate today's data-hungry workflows.
