Unlock Fleet-Wide Storage Management with ‘Just Enough’ LDAP

If you’ve looked at Everpure Fusion™ and thought, “This is exactly how I want to manage storage,” you’re not alone. A single intelligent control plane, fleet‑wide policies, and Storage‑as‑Code™ are a big step up from managing one array at a time.

Then reality hits:

“Everpure Fusion requires LDAP… and we don’t use that today.”

For some teams, that’s where the conversation stalls. Lightweight Directory Access Protocol (LDAP) and a directory service such as Active Directory or an identity provider (IdP) such as Okta are used by Everpure Fusion to make sure the right users can manage your data estate. And directory services sound like more infrastructure, more security review, and possibly a whole IAM project you didn’t sign up for.

The good news: To unlock Everpure Fusion, you don’t need to rebuild identity for your entire company. You need just enough LDAP to give Everpure Fusion a trustworthy, centralized way to answer two questions across your fleet:

1. Who is this admin?
2. What are they allowed to do on any array in this fleet?

Everything else can stay where it is today.

Why Everpure Fusion makes identity a hard requirement

On a single FlashArray™ or FlashBlade^®, local users are fine. One box, a few admins, some scripts—that works.

Everpure Fusion changes the scope in order to solve problems:

• You’re managing fleets, not individual boxes.
• Policies and presets apply across arrays and sites.
• Automation replaces hand‑built runbooks.
• Governance stops being a “nice-to-have” and becomes table stakes.

In that world, local accounts don’t scale—and for Everpure Fusion, they simply don’t work for remote operations. Only directory‑backed users can safely join arrays into fleets and run cross‑array commands.

That’s where LDAP comes in: not as a new identity strategy, but as the directory backbone Everpure Fusion plugs into.

What does ‘just enough’ LDAP for Everpure Fusion look like?

The model that works well for existing Everpure customers is deliberately narrow:

• Read‑only directory access from the arrays
• A small set of admin groups (e.g., PF_Admin, PF_Operator, PF_ReadOnly)
• Clean group to role mappings on every Everpure Fusion‑enabled array
• A low‑privilege bind user scoped to the OU that holds those groups
• TLS‑only (LDAPS/StartTLS) connections with real certificates
• Identity lifecycle (joiners/movers/leavers) staying in your existing IAM flow

In other words, LDAP acts as a thin, secure adapter between Everpure Fusion and the identity system you already trust—rather than a whole new identity world you have to build and run.

What you gain (and what you don’t lose)

With that minimal setup in place, Everpure Fusion enables:

• Fleet‑wide provisioning from a single control plane
• Policy‑driven governance via presets and workloads
• Consistent RBAC across arrays, instead of per‑box snowflakes
• Cleaner audits and offboarding, because “who’s an admin?” is answered in one place

Crucially, a scoped LDAP integration doesn’t turn Everpure Fusion into your identity authority. It remains a consumer of directory data, enforcing roles on the storage side while IAM and security own the directory.

There are some tradeoffs to this minimal approach. You’re choosing explicit, group‑based roles over fancy attribute‑based access control. You’re accepting that directory availability is now part of your management‑plane resilience story. And you’re involving IAM/security in naming, TLS, and governance.

But for most environments that are growing beyond a couple of arrays, those are smart trades to make. Especially when these tradeoffs come with all the benefits that Everpure Fusion delivers to you and your team: managing all of your data, with more confidence, using less time and resources.
