From Physical Layout to Enforced Policy with Everpure Fusion Topology Groups

The placement gap in modern infrastructure

IT Infrastructure teams must know where workloads run and how they perform, since data location, tenant isolation, latency, throughput, and operational consistency all hinge on placement decisions. Often this context lives only in tribal knowledge, spreadsheets, and scripts rather than in the provisioning workflow, making every placement a manual judgment call that grows harder to enforce as fleets scale across data centers and regions. This reveals a placement gap: A unified fleet view isn’t enough without control over where workloads are permitted to live. Organizations must still enforce data residency rules, availability zones, tenant isolation, disconnected sites, and infrastructure class requirements. Lacking a shared model for these boundaries, teams resort to silos, per array scripts, and operator expertise, approaches that scale poorly, invite human error, cause configuration drift, and complicate audits.

A better operating model with Everpure Fusion

Everpure Fusion™ helps organizations operate storage as a unified, policy-driven fleet rather than a collection of independently managed arrays. It provides a common control plane for defining storage standards and applying them consistently across the environment.

Topology groups extend that model by bringing physical structure into the placement workflow. They allow you to represent the topology and use it as a boundary for workload placement: from a simple regional layout to a nested hierarchy of regions, zones, and domains.

How Everpure Fusion topology groups work

Topology groups are folder-like structures that organize arrays into a hierarchy reflecting the way an organization designs and operates its infrastructure. An array or a group of arrays belongs in one place in the hierarchy, creating a clear, unambiguous model of the fleet. 

A global organization might define a top-level group for each region, then create child groups for availability zones and domains. Similarly, a service provider might model infrastructure domains that logically represent their tenant boundaries. Another team may only need a flat grouping of arrays by location. No matter how the infrastructure is distributed, Everpure Fusion simplifies creating, managing, and securing arrays similar to a public cloud-like environment. 

Everpure Fusion uses placement policies to guide workloads toward appropriate infrastructure and prevent placement outside the boundaries, making it secure. For instance, a compliance-sensitive workload can be constrained to an approved infrastructure in a country or a region. Similarly, applications with common availability requirements can be placed within the appropriate zones. 

Everpure Fusion evaluates topology rules whenever a placement request is made through the GUI, REST API, CLI, or natural language via MCP. During workload placement, Everpure Fusion prevents boundary violations by making sure that the workload policy and the corresponding topology groups have an eligible array in common. The result is a placement decision that is secure, repeatable, and defensible.

In addition, Everpure Fusion has doubled the number of arrays supported per fleet, giving teams one logical, scalable foundation for creating and managing their topology. Instead of maintaining separate structures and policies for multiple fleets, teams can organize arrays across regions, availability zones, and domains in a single hierarchy. New arrays, sites, or expansion rows can be added to the appropriate topology group as the environment evolves. It also makes topology-aware placement more useful. A policy can evaluate eligible infrastructure across a large fleet while still honoring the boundaries defined by topology groups. You gain the flexibility of a large resource pool without losing the geographic, physical, and logical context required for resiliency, locality, and isolation.

By combining fleet scale with a unified policy engine, Everpure Fusion helps administrators apply storage policies consistently across the fleet rather than synchronizing rules or scripts across fragmented environments. You can start with the boundary that matters most today—a region, a data center, or a tenant domain—and expand the topology over time without a disruptive fleet-wide redesign. These controls help prevent a hierarchy change from quietly undermining policies that depend on it.

Key benefits of Everpure Fusion topology groups

• Context-aware placement: Topology groups give Everpure Fusion the context to guide workloads to infrastructure that meets geographic, physical, or logical criteria, improving VMware datastore placement, strengthening data residency controls for databases, and enhancing data locality for apps.
• Less manual work, less script sprawl: Fleet structure becomes a managed object that IT teams can create, list, rename, and update, reducing repetitive edits across scripts, CMDB records, and runbooks.
• Shared source of truth: IT teams can export topology to a CMDB and trace an array’s place in the hierarchy instantly, giving infrastructure, security, and audit teams aligned visibility.
• Scalability across growing fleets: Everpure Fusion has doubled the number of arrays supported in a single managed fleet, letting organizations model distributed environments without splitting into smaller silos.
• Reliable policy foundation: Built-in safeguards prevent deleting nonempty or referenced groups, validate moves for cycles and depth limits, and check renames for naming collisions.

Start with the boundary that matters most

The path to policy-driven operations does not need to begin with a complete infrastructure redesign. Start by identifying the boundary that creates the most risk or manual work today:

• A regional or country residency requirement
• A tenant-isolation requirement
• A secure or disconnected site
• A compute or database workload that must land on specific infrastructure

Model that boundary in a topology group, connect it to a placement policy, and use it for the next workload. Each policy replaces another manual judgment call with a consistent outcome.

Everpure Fusion topology groups help organizations move from simply knowing where infrastructure is to governing where workloads can go, keeping physical layout, operational practice, and business requirements aligned as the fleet scales.
