PANZURA CLOUDFS® MIGRATION PATH

Your NetApp GFC Infrastructure is Now Unsupported.

NetApp announced the End of Availability (EOA) for Global File Cache on May 31, 2024, and the edge caching service was removed on August 7, 2024, from the BlueXP platform (now NetApp Console). Organizations still running GFC are operating on legacy infrastructure without vendor support, security patches, or cloud API updates—creating mounting operational and security risk.

While NetApp directs customers toward FlexCache or FlexGroup (Volume Caching) as alternatives, these technologies are not designed for high-performance global collaboration. Only Panzura CloudFS delivers the real-time global locking and AI-powered threat protection your distributed workflows require.

What Actually Happened?

Your organization invested in NetApp Global File Cache because it solved a real problem—distributed collaboration without version conflicts. GFC delivered centralized data control, local performance, and file locking that prevented costly overwrites. Then NetApp removed Edge Caching from BlueXP entirely. No migration path. No direct replacement.

aleting-history The platform your distributed teams depend on is now unsupported infrastructure. This is a ticking clock. The question isn't whether to migrate, but where.

RISK ASSESSMENT

The Cost of Staying Unsupported

Every day on legacy GFC infrastructure compounds operational debt and security exposure.

Risk Category
Impact of Inaction
Security Exposure
No security patches means increasing vulnerability to cyber threats. Ransomware attackers specifically target known unpatched systems.
Operational Risk
If a Windows update breaks the GFC agent or cloud orchestration fails, there is no vendor support. Recovery could take days or weeks.
Supportability Deficit
No path for vendor troubleshooting or technical assistance. If the system hangs or data becomes inaccessible, your internal IT team is entirely on its own.
Compliance Gaps
Running unsupported software may violate security policies, audit requirements, and regulatory mandates like GDPR or HIPAA that require current vendor support.
Performance Degradation
Legacy software without maintenance updates inevitably slows as datasets grow. Latency increases over time, frustrating users and stalling workflows.
Productivity Impact
Any service disruption stops distributed teams from accessing critical files. For AEC and manufacturing firms, this means project delays and missed deadlines.

FLEXCACHE ANALYSIS

Why NetApp's Suggested Path Possibly Falls Short

NetApp directs GFC customers to FlexCache or FlexGroup (Volume Caching)—technologies designed primarily for read acceleration rather than high-performance, real-time collaborative locking. The critical issue is what happens when connectivity drops. NetApp's own documentation states: "With global file locking enabled, modifications to the origin volume are suspended until all FlexCache volumes are online." A network hiccup at your smallest location could freeze save operations globally.

resilient-data-icon
File Locking Problem

FlexCache requires all cache sites to maintain connectivity to the origin to permit write operations. Changes to the origin volume are not available until all FlexCache volumes are active.

caution-icon
Failure Cascade Risk

If a single branch office loses internet connectivity, a global write lock potentially engages, freezing save access for the entire organization. One network hiccup shouldn't freeze productivity worldwide.

file-collaboration-icon
Lacks Granular Locking

FlexCache lacks the byte-range locking necessary for simultaneous editing and collaboration in critical applications like Autodesk Revit, AutoCAD, and Microsoft Excel across distributed teams.

TECHNICAL COMPARISON MATRIX

CloudFS Advantage: Stop Constantly Working Around System Limitations

The differences between file caching solutions determine whether your distributed teams can actually collaborate in real-time or whether they're constantly working around system limitations. Three architectural decisions matter most: how the system handles locking (file-level vs. byte-range), how it responds to site failures (cascade vs. isolation), and where data lives (expensive block storage vs. cost-efficient object storage). The comparison below examines these capabilities and more across your three options: staying on unsupported GFC, migrating to NetApp's FlexCache, or moving to Panzura CloudFS.

CLOUDFS ARCHITECTURE

Not a Cache Layered on Storage. CloudFS is a Complete Platform.

Cache-on-top-of-storage architectures bolt distributed collaboration onto systems designed for something else. CloudFS is a global file system from the ground up—data lives in cost-efficient object storage while local nodes at each office connect through a peer-to-peer full mesh topology. No central origin bottleneck. No single point of failure. Every node maintains complete metadata for the entire file system and retrieves data directly from wherever it lives—local cache, cloud, or another office. The result: local-speed access to a single authoritative dataset with no synchronization lag or version conflicts.

architecture-icon

Peer-to-Peer Full Mesh

Local nodes connect to both cloud object storage and every other node. Sites retrieve data directly from each other—no single point of failure, no origin dependency.

remote-collaboration

Distributed Byte-Range Locking

Multiple users edit different sections of the same file simultaneously. User A modifies the 3rd floor of a Revit model while User B works on the roof—both in the same file, without conflict.

tc-stop-threat-icon

AI-Powered Threat Control

Threat Control for CloudFS delivers ML-based behavioral fingerprinting that proactively detects ransomware and exfiltration. It interdicts threats by disabling compromised users only—no site-wide "blast radius."

security-icon

Immutable Object Storage

Write-Once-Read-Many architecture on standard object storage (AWS S3, Azure Blob, GCS). Data never overwritten—ransomware and malware cannot encrypt base data blocks and accidental data loss is a thing of the past.

Panzura-FIPS-140-3

FIPS 140-3 Certified Security

The only solution in its category with FIPS 140-3 certification means encryption for data at rest and in transit. Compliance-ready for highly regulated engineering and government environments.

time-reverse-icon

60-Second Metadata Sync

All nodes synchronize changes across the network every 60 seconds (configurable). Every node holds the complete metadata copy for the entire file system.

 

COMPETITIVE LANDSCAPE

Why CloudFS Wins Against Alternatives

Every distributed file system vendor has positioned their solution as the natural GFC successor. But architectural differences matter—especially for large CAD files, BIM models, and data-intensive collaborative work. The key differentiator is how each platform handles real-time locking, failure isolation, and technical workflow performance. Panzura CloudFS remains the only platform that solves the “Distributed File Dilemma” without the 
“synchronization lag” found in competitor hub-and-spoke models. 

Solution
Why Panzura CloudFS is Superior
Nasuni
Nasuni utilizes a hub-and-spoke architecture that can suffer from latency in heavy collaborative environments. CloudFS’s peer-to-peer mesh provides faster sync and superior byte-range locking.
CTERA
CTERA is often positioned as a gateway-heavy solution. CloudFS’s software-defined approach provides greater flexibility across multi-cloud environments without proprietary hardware lock-in.
Egnyte
Egnyte is primarily a file sharing (EFSS) solution. It lacks the robust, block-level global locking and high-performance local caching required for large-scale CAD, Revit, or media workloads.

BYTE-RANGE LOCKING

Applications That Support True Co-Authoring with CloudFS

Byte-range locking with CloudFS is what makes true real-time collaboration possible on complex files. Instead of locking an entire file when someone opens it—forcing colleagues to wait or risk overwriting each other's work—byte-range locking allows different users to edit different sections of the same file simultaneously.

Consider a Revit model of a large building. With file-level locking, only one person can work on it at a time. With CloudFS, your structural engineer in Chicago can modify the foundation while your MEP engineer in London works on the HVAC systems and your architect in Singapore refines the façade. All in the same model file, at the same time, without conflicts. It's the difference between teams working in parallel versus working in sequence. Here's a list of some of the critical applications that support byte-range locking with CloudFS.
