Rewriting the Rules of Storage: Evergreen//One Adaptive Tiers

Enterprise workloads have entered a new era—more dynamic, more mixed, and more unpredictable than ever before. Application estates evolve monthly, not annually; AI training cycles surge and retreat; analytics jobs swing between steady-state and burst behavior; and backup windows spike capacity movement. In the public cloud, elasticity has become the default expectation for handling this variability. Yet in the enterprise data center—where organizations demand the highest levels of security, dependability, and control—storage architectures still rely on rigid, predefined tiers and fixed bundles of performance and capacity that struggle to keep pace with modern workload behavior.

These legacy approaches weren’t built for the way organizations work today. They slow innovation, elongate pipelines, and lock teams into costly architectural choices. The real problem isn’t the complexity of workloads—it’s the limitations of infrastructure that can’t adapt to them.

Evergreen//One™ Adaptive Tiers rewrites these rules, replacing rigid infrastructure with a service-defined model that flexes with your workloads, eliminates unnecessary data movement, and restores productivity through simplicity and control.

Breaking the Link between Performance and Capacity

For decades, storage has forced a simple but painful trade-off:

• Need more performance? Buy more capacity—even if you don’t need the TBs.
• Want economical capacity? Accept slower performance and longer workflow cycles.

This tight coupling is a core flaw in traditional architectures.

Adaptive Tiers breaks this connection entirely. With Evergreen//One, organizations reserve capacity and performance independently, scaling each on demand as workloads evolve. Instead of prepackaged tiers, you define the service outcomes you need—IOPS, bandwidth, latency, and storage footprint—and the service delivers those outcomes under SLA.

The result is storage that truly adapts, without re-architecture, without workload shuffling, and without overbuilding “just in case.”

Why Static Architectures Fail Modern Workloads

Today’s workloads behave nothing like the steady, predictable applications that classical tiering was built for. A few common examples illustrate the problem:

• Backup repositories need cheap, deep capacity with burst performance during backup and restore cycles.
• Analytics pipelines require sustained throughput that doesn’t degrade as data sets grow.
• ML feature stores demand high, consistent performance on a moderate data set.
• Scratch or dev/test spaces spike performance temporarily, but don’t justify permanently overprovisioned hardware.

Traditional storage treats these very different workloads as if they belong on rigid performance tiers—forcing teams to continuously rebalance, migrate, or re-tier data.

This leads to chronic inefficiency:

• Data is copied between scratch, staging, and data lakes, creating complex, slow pipelines.
• Teams overprovision to avoid outages, inflating cost and energy consumption.
• Architects plan environments around limitations rather than around actual behavior.

Adaptive Tiers solves these structural problems by aligning storage performance with real workload patterns—not arbitrary labels.

A Unified Data Space for Faster, Cleaner Pipelines

One of the biggest sources of operational friction is the constant movement of data between tiers to get the right performance profile. In analytics environments, for example, teams often:

• Land data in a low-cost data lake
• Copy it into scratch space for processing
• Move results back into colder storage for long-term use

Every copy adds latency, introduces risk, and increases operational overhead.

The Evergreen//One Adaptive Tiers service replaces this fragile workflow with a single logical data space where performance can be dialed up without moving data. Analysts and data scientists work on the same data footprint throughout the lifecycle of a workload, with performance adjusted precisely to the level needed—for instance, based on peak model training cycles or heavy transformation jobs.

This eliminates pipeline sprawl and drastically shortens time to insight.

What Makes Evergreen//One Adaptive Tiers Different

Decoupled Performance and Capacity

You reserve only the capacity you need and only the performance you need—no more buying one to get the other. This flexibility reduces overspend and ensures consistent performance across critical workloads.

Non-disruptive Adjustments as Workloads Evolve

Performance reserves can be increased instantly without migrations, downtime, or complex planning. Seasonal patterns, new workloads, or shifting demand are absorbed seamlessly.

Delivered as a Fully Managed Service

Adaptive Tiers leverages the Evergreen//One service model with:

• SLA-backed availability and performance
• Evergreen non-disruptive upgrades
• Hardware ownership and lifecycle handled by Pure Storage
• Unified operational intelligence through Pure1^®

This reduces operational overhead and keeps infrastructure continuously optimized.

Economics That Follow Value, Not Guesswork

Instead of capital-heavy tiering decisions or repeated reinvestment cycles, organizations scale incrementally based on measured usage and actual workload value. Costs align naturally to business drivers rather than speculative projections.

Smarter Sustainability through Efficiency

Right-sized performance reduces stranded hardware, lowers power and cooling consumption, and minimizes physical footprint. Adaptive Tiers helps deliver on sustainability commitments without compromising SLAs.

A Foundation for Service-defined Infrastructure

Evergreen//One Adaptive Tiers marks a fundamental shift from infrastructure-defined limitations to service-defined flexibility. By decoupling capacity from performance, enabling non-disruptive adjustments, and eliminating unnecessary data movement, it empowers organizations to build architectures around how workloads truly behave.

This is how the rules of storage get rewritten:

• No rigid tiers
• No repetitive migrations
• No forced trade-offs

Just programmable, flexible, SLA-backed service levels that evolve with your business.
