PowerScale for Azure: Dell High Performance Enterprise File Storage in Cloud

Dell’s move to bring PowerScale directly into the Azure control plane signals a meaningful shift for enterprises that need high-performance file storage in the cloud without giving up the OneFS feature set and operational model they rely on today.

Background / Overview​

Dell PowerScale for Microsoft Azure is an Azure‑native, co‑developed offering that packages Dell’s OneFS scale‑out filesystem as a transactable resource inside the Azure Portal and Marketplace. It is being presented in two deployment models: a Customer‑Managed model (deploy OneFS on Azure VMs and manage it yourself) and a Dell‑Managed Azure‑native model where Dell provisions and operates the underlying infrastructure while customers consume a managed filesystem from their Azure subscription. This managed path is billed through Azure Marketplace and integrates with Azure role‑based access and monitoring. Dell positions this as an enterprise‑grade solution for throughput‑sensitive workloads — AI/ML training, HPC, Electronic Design Automation (EDA), Media & Entertainment (M&E), and large‑scale analytics — by combining OneFS data services, multi‑protocol access, and dedicated compute SKUs tuned for PowerScale.

---

What PowerScale for Azure delivers: the facts IT teams should know​

Native Azure integration and managed operations​

• The Dell‑managed edition surfaces PowerScale as an Azure Marketplace resource with integration into Azure Resource Manager, portal visibility, and Marketplace billing. This simplifies procurement and allows use of existing Azure enterprise agreements and consumption commitments.
• The Customer‑Managed edition remains available for teams that require maximum control over configuration, networking, lifecycle management, and data residency.

OneFS capabilities preserved​

PowerScale’s OneFS brings enterprise file services to Azure consistent with the on‑prem experience:

• Single global namespace with multi‑protocol access (NFS v3/v4, SMB3, S3, HDFS).
• Built‑in data services: snapshots, inline compression, SmartDedupe, SmartLock immutability, SmartConnect load balancing.
• Policy‑driven cloud tiering via CloudPools and asynchronous replication via SyncIQ for hybrid DR and cloud‑burst workflows.

Performance and NVRAM‑enabled compute SKUs​

Dell advertises custom NVRAM‑enabled compute SKUs engineered exclusively for PowerScale on Azure and claims up to 4× the performance of its closest competitor for read throughput per namespace. This is presented as an engineering differentiation designed to offer ultra‑low latency and higher throughput for data‑intensive workloads. This is a vendor claim and should be validated in a proof‑of‑concept under your workload profile.

Scale and namespace limits — verified vs reported numbers​

• Dell’s product documentation and solution briefs for the Customer‑Managed PowerScale on Azure edition state guidance of up to 18 nodes and ~5.6 PiB (pebibytes) of usable cluster capacity for an Azure cluster. That 5.6 PiB guidance is an important planning baseline for self‑managed deployments.
• Several vendor briefings and independent outlets report a larger 8.4 PB single‑namespace figure associated with the new Dell‑Managed Azure‑native edition. Microsoft’s partner announcement and press coverage list up to 8.4 PB for the managed offering, but Dell’s public documentation for the managed variant had incomplete or evolving capacity disclosures at the time of writing. Treat the 8.4 PB number as reported by Microsoft and third parties but not yet fully codified as a contractual guarantee; obtain written capacity and throughput limits from Dell when planning production deployments.

---

Why enterprises will care: use cases and practical value​

AI, ML and HPC pipelines​

Parallel file access and scale‑out throughput are essential for large model training, feature engineering, and dataset preprocessing. PowerScale’s ability to present the same dataset over NFS/SMB and S3 simultaneously, combined with high concurrency and low‑latency reads, makes it suitable as a data plane for GPU clusters and Azure AI compute. The Dell messaging specifically ties the managed service to Azure GPU compute and AI workloads.

Media & Entertainment (M&E)​

High‑bandwidth ingest, real‑time editing, collaborative workflows, and tiered archiving are classic PowerScale strengths. CloudPools can archive cold assets to Azure Blob while present a unified namespace for production teams, simplifying hybrid media pipelines.

Electronic Design Automation and Life Sciences​

Both EDA and genomics require high throughput and predictable I/O under highly concurrent access. PowerScale for Azure aims to reduce data movement friction and let teams leverage burst compute in Azure without rearchitecting storage footprints.

Disaster Recovery and Ransomware resilience​

SyncIQ asynchronous replication within Azure and to on‑prem clusters extends DR posture across environments. OneFS snapshotting plus SmartLock and other immutability features are marketed as part of a zero‑trust, ransomware‑resilient model. Confirm backup SLAs and recovery times as part of contractual negotiation.

---

Security, governance and operational control​

Security posture​

Dell highlights a zero‑trust architecture, always‑on encryption, and built‑in ransomware recovery primitives in the managed offering. These design points are consistent with enterprise expectations for production workloads, but the precise controls (telemetry residency, key management model, audit log retention, and the location of forensic copies) must be validated with Dell and Microsoft to meet regulatory or internal compliance requirements.

Governance and telemetry​

Managed services introduce a third‑party control plane. Important questions for security and compliance:

• Do audit logs and telemetry remain in your subscription, or are they managed within Dell’s control plane?
• Are encryption keys customer‑managed (CMKs) or vendor‑managed?
• What are the region/fidelity guarantees for data residency and where are backups stored?
  These are operational controls that must appear explicitly in service agreements before production rollout.

---

Strengths — what PowerScale for Azure does well​

• Familiar OneFS experience: Preserves feature parity for organizations already using PowerScale on‑prem: snapshots, SmartDedupe, SmartLock, and multi‑protocol access all remain available as part of the OneFS experience. This reduces re‑tooling for applications that depend on POSIX semantics or SMB.
• Hybrid continuity: CloudPools and SyncIQ enable staged migrations, cloud bursting, and hybrid DR patterns without forcing a full replatform to native object semantics.
• Managed consumption through Azure Marketplace: Billing and procurement integration simplify billing consolidation and permit use of enterprise Azure commitments. For many organizations, this reduces procurement friction and shortens time‑to‑pilot.
• Purpose‑built compute SKUs and performance claims: NVRAM‑enabled compute SKUs are an architectural differentiator aimed at delivering higher read throughput and lower latency for parallel workloads. Vendor testing claims substantial improvements, which can translate to faster training runs and shorter job turnaround for data‑heavy workloads — after validation.

---

Risks, caveats and where to push back during procurement​

1) Vendor claims vs contractual guarantees​

Vendor benchmark claims — such as “up to 4× performance” — are useful as orientation but must be validated under your workload and secured in contract when throughput or latency SLAs are business‑critical. Run a PoC that replicates real concurrency and dataset sizes.

2) Capacity and published limits are not yet uniform​

Different sources report different maximums: Dell’s customer‑managed guidance (18 nodes, ~5.6 PiB) is documented; Microsoft’s partner messaging and press reports cite the managed offering at 8.4 PB in a single namespace. That larger figure should be treated as reported but not yet contractual until Dell or Microsoft include it in the managed service documentation and offer terms. Ask for written capacity limits and export guarantees during procurement.

3) Data gravity and exit strategy​

Moving multi‑petabyte datasets into a Dell‑operated resource inside Azure may increase data gravity and create migration friction or unexpected egress costs. Model exit scenarios: how are bulk exports handled, what are egress speeds, and are there tools for staged migration back to on‑prem or another cloud? Confirm costs and timelines for data export in the service agreement.

4) Network topology, delegated subnets, and performance variability​

Azure‑native integrations typically require delegated subnets and specific networking constructs. Public cloud network variability (noisy neighbors, VM host variability) can affect performance predictability. Validate network designs (NSGs, Private Link, ExpressRoute) and test end‑to‑end latency under representative load.

5) Security and compliance surface of a managed service​

A managed model replaces some direct control with vendor operations. Confirm the following:

• Who controls keys? CMK vs vendor key models.
• How long are audit logs retained, and where are they stored?
• What is the incident response and escalation SLA, and who owns RTO/RPO guarantees?
  These must be contractual.

---

Practical checklist for evaluation and deployment (actionable steps)​

• Clarify the target edition (Dell‑Managed vs Customer‑Managed) and map responsibilities for patching, monitoring, and compliance.
• Obtain written capacity, node, and throughput guarantees for the targeted edition (don’t rely solely on press or vendor marketing). Verify whether the 8.4 PB figure applies to your region and is contractual.
• Run PoC tests with representative workloads (AI training, EDA simulation, multi‑user M&E editing). Measure throughput, latency, and concurrency under production‑like load.
• Model full TCO including storage, snapshots, CloudPools archival charges, cross‑region replication, and network egress. Include snapshot retention, metadata costs, and potential CloudPools restore patterns.
• Validate security controls: CMK support, audit log residency, SIEM integrations, Private Link/endpoint support, RBAC/ABAC patterns with Microsoft Entra. Get these details in writing.
• Confirm backup and DR flows: test SyncIQ failover/failback, CloudPools restores, and PowerProtect integration if used for long‑term retention.
• Negotiate exit and data export terms: bulk export bandwidth, timeframes, and supported tooling. Include cost ceilings or credits for long egress operations where possible.

---

Cost modeling and procurement tips​

• Include Azure Marketplace billing mechanics and how they interact with your Azure Consumption Commitment or Enterprise Agreement. Managed offerings billed through Marketplace may be eligible for committed spend offsets, but specifics vary by contract. Confirm with your Azure account team.
• Snapshot and replication frequency materially affect storage costs; model snapshot retention windows and the cost of CloudPools archival to Azure Blob, which will incur tiered storage and egress costs on recall.
• For burst scenarios (e.g., training large models on GPU farms), include temporary compute costs and any cross‑zone traffic pricing in your PoC cost model. Network egress between zones/regions can dominate costs when datasets are large.

---

How PowerScale for Azure fits into a long‑term hybrid strategy​

PowerScale for Azure represents an approach that keeps enterprise file semantics intact while enabling a cloud‑native operational model for consumption and procurement. For organizations that depend on POSIX semantics, SMB shares, or require advanced OneFS data services, this offering reduces replatforming risk and lowers operational lift (if choosing the Dell‑Managed path). For organizations with strict compliance or custom networking needs, the Customer‑Managed path preserves control. A balanced strategy:

• Start with non‑critical workloads or DR/test datasets in the Dell‑Managed preview.
• Validate performance, security, and billing models via PoC.
• Stage migration of critical production datasets only after contractual SLAs, capacity guarantees, and exit procedures are in place.

---

Final assessment — measured enthusiasm with due diligence​

Dell PowerScale for Azure brings a compelling blend of enterprise OneFS features and Azure‑native consumption. For teams wrestling with petabyte‑scale file estates and throughput‑hungry workloads, it promises to simplify cloud adoption while preserving application semantics that are otherwise costly to rework.
However, this is a vendor‑managed evolution in a still‑maturing product landscape. Key vendor claims — notably the up to 4× performance figure and the 8.4 PB single‑namespace number for the managed edition — are powerful marketing points but must be validated and contractually secured. Use the Dell‑Managed offering as a strategic tool to accelerate pilots and AI bursts, but insist on proof‑of‑concepts, written capacity and throughput limits, security attestations, and explicit exit plans before moving mission‑critical production data.
In short: PowerScale for Azure can materially reduce operational friction and deliver high‑performance file storage in the cloud, but prudent procurement and engineering validation are mandatory. When paired with rigorous PoCs, careful contractual terms, and a staged migration plan, it becomes a strong candidate for enterprises scaling data‑intensive workflows into Azure.

---

Conclusion
Dell PowerScale for Azure is more than another cloud storage SKU — it is an attempt to bring enterprise‑grade file semantics and data services into the Azure user and procurement experience. Its strengths for AI/ML, EDA, M&E, and hybrid DR are real; the path to deriving value runs through careful validation of capacity, performance, security, and exit options. Treat vendor performance and scale claims as starting points for technical verification and contractual negotiation; do that, and PowerScale for Azure can be an effective, high‑performance file storage foundation for enterprise cloud initiatives.

[ChatGPT]

Dell and Microsoft have quietly turned a familiar on‑premise workhorse into an Azure‑native option: Dell PowerScale — the OneFS scale‑out file system that many enterprises rely on for high‑performance unstructured data — is now available as a Dell‑managed, transactable service in the Azure Portal under a public preview, while the customer‑managed PowerScale on Azure path remains supported for teams that need full control.

Background​

Enterprise storage vendors have long wrestled with a simple problem: how to preserve the advanced data services customers depend on while making those services consumable in hyperscaler clouds. Dell’s PowerScale has been a staple in media, HPC, genomics, EDA, and large‑scale analytics because of OneFS’s single global namespace, multi‑protocol access, and data services (snapshots, dedupe, SmartLock immutability, CloudPools tiering, SyncIQ replication). The new public preview introduces a second, Dell‑managed pathway that integrates PowerScale directly into Azure’s control plane and Marketplace, shifting management of the underlying platform to Dell while exposing the filesystem as a native resource in customers’ Azure subscriptions.
This shift matters because enterprises are increasingly faced with two options: re‑platform applications for cloud‑native object stores, or bring enterprise storage features into the cloud as a managed service. Dell’s approach gives customers both choices: keep the customer‑managed OneFS deployment in their Azure subscription, or opt for a Dell‑operated, Azure‑native variant billed and consumed via Azure Marketplace.

---

What Dell PowerScale for Microsoft Azure actually is​

Two deployment models, different responsibilities​

• Customer‑managed PowerScale on Azure: You deploy OneFS on Azure VMs, choose instance sizes, manage networking, lifecycle, patches, and monitoring. This remains the path for teams requiring deep customization, specific compliance postures, or tight network control.
• Dell‑managed (Azure‑native) PowerScale / APEX File Storage for Microsoft Azure: Dell provisions and operates the infrastructure and OneFS software; the filesystem surfaces as an Azure resource that can be provisioned through the Portal and billed via Marketplace. This model simplifies procurement and day‑to‑day operations while integrating into Azure RBAC and Azure Monitor telemetry.

Core OneFS capabilities preserved (vendor claim)​

Dell says the managed service preserves OneFS’s signature capabilities:

• Single global namespace across nodes
• Multi‑protocol access (NFS v3/v4, SMB3, HDFS, S3)
• Data services: snapshots, inline compression, SmartDedupe, SmartQuotas, SmartConnect load balancing, SmartLock (WORM/immutability)
• CloudPools policy‑driven tiering to Azure Blob storage
• SyncIQ asynchronous replication for hybrid DR

These capabilities are described as consistent with on‑prem PowerScale behavior and are central to the value proposition for workloads that rely on POSIX semantics or parallel file access.

---

Verified technical claims and where to be cautious​

Capacity and scale: what is documented vs what’s been reported​

Dell’s published guidance for the customer‑managed PowerScale on Azure edition lists cluster planning guidance of up to 18 nodes and roughly 5.6 PiB (pebibytes) of usable cluster capacity for that deployment path. That figure appears in Dell’s product and admin documentation for cloud deployments and is a concrete planning baseline for self‑managed clusters.
However, several press reports and partner announcements have mentioned a larger 8.4 PB single‑namespace figure attributed to the new Dell‑managed Azure‑native edition. That 8.4 PB number appears in external coverage but was not fully codified in Dell’s public product pages or in the marketplace materials at the time of initial reporting. Treat that number as reported but unverified until Dell provides it in written, contractual documentation. Enterprises must request explicit capacity guarantees from Dell before planning production workloads around that limit.

Performance claims: vendor numbers should be validated​

Dell has promoted NVRAM‑enabled compute SKUs tuned for PowerScale on Azure and cited performance delta claims — for example, statements like “up to 4× the read throughput per namespace compared with the closest competitor.” These are vendor benchmarking claims useful for orientation, but they are workload dependent and must be validated with proof‑of‑concept (PoC) testing under representative concurrent loads. Any throughput or latency SLAs you rely on should be contractually secured.

Security and compliance — questions that require contractual clarity​

Dell and Microsoft position the managed service as enterprise‑grade with zero‑trust and always‑on encryption, and they highlight ransomware‑resilience features such as SmartLock immutability and snapshot‑based recovery. That said, managed services introduce additional governance questions:

• Where do audit logs and telemetry live (customer subscription vs Dell control plane)?
• Are encryption keys customer‑managed (CMK) or vendor‑managed?
• What are the data region guarantees and residency limits for backups and immutable copies?
• How are SLAs for recovery time and point defined and enforced?

These are operational controls that must appear explicitly in service agreements and data‑processing addenda before any production migration.

Why enterprises will consider PowerScale for Azure​

Natural fit for throughput‑sensitive, file‑centric workloads​

PowerScale’s OneFS architecture is purpose‑built for parallel I/O and high concurrency. In Azure, this can be particularly compelling for:

• AI/ML training data planes that need the same dataset exposed via NFS/SMB and S3 semantics to different consumers.
• HPC and EDA workflows that require predictable, high throughput and consistent POSIX semantics.
• Media & Entertainment pipelines with high‑bandwidth ingest, collaborative editing, and tiered archiving.
• Life sciences and genomics where dataset sizes and concurrency are demanding.

Dell explicitly ties the managed offering to Azure GPU compute and AI services, framing PowerScale as a data plane that reduces the need to re‑architect datasets for native object stores. For teams adopting Azure AI tooling, the Azure‑native consumption model and Marketplace procurement reduce friction for spinning up trials and PoCs.

Hybrid continuity and phased migration​

PowerScale’s CloudPools tiering and SyncIQ replication are the primary hybrid‑cloud mechanisms: CloudPools allows policy‑based archiving to Azure Blob while keeping smartlinks in the active namespace; SyncIQ supports asynchronous replication across clusters for DR and cloud bursting. Those features enable staged migrations and hybrid DR scenarios without forcing applications to be refactored for object storage. This hybrid continuity is a practical advantage for organizations unwilling or unable to do a full replatform.

---

Operational and commercial implications​

Procurement and billing​

Because the Dell‑managed PowerScale edition is provisioned through the Azure Marketplace as an ISV integration, customers can often apply existing Azure enterprise agreements, private offers, and consumption commitments. Billing and chargeback become parts of the Azure subscription model rather than a separate Dell invoice, which can simplify internal finance workflows and help optimize contractual discounts. However, this shifts some vendor/reseller dynamics — organizations must map who in procurement signs off on Marketplace purchases and how private offers are handled.

Support boundaries and exit strategy​

In the managed model Dell is the primary platform operator, which consolidates support for infrastructure and OneFS. That simplifies vendor interactions for customers but creates dependencies on Dell’s operational SLAs and responsiveness. Important questions to negotiate before production:

• Escalation paths for outages and security incidents
• SLAs for patching and maintenance windows
• Data egress and export procedures if you decide to transition away
• Contractual guarantees for capacity and throughput as your dataset grows

Organizations should build an exit and portability plan into contracts to avoid being locked into a particular managed configuration without clear data export paths.

---

Practical checklist for IT teams evaluating the public preview​

Run a scoped, instrumented evaluation that answers these concrete questions before committing production datasets.

1. Define representative workloads
   • Select the exact training jobs, HPC workflows, or file operations that reflect real concurrency and dataset sizes.
2. Performance validation (PoC)
   • Measure throughput, latency, IOPS, and concurrency at scale.
   • Compare the Dell‑managed Azure SKUs vs your current on‑prem nodes and against alternative cloud storage patterns.
   • Validate NVRAM‑enabled SKU claims under real data access patterns.
3. Capacity and scale verification
   • Obtain written maximum filesystem and node counts for the managed edition.
   • Model dataset growth and ask Dell for contractual capacity expansion terms.
4. Security, key management and telemetry
   • Confirm whether CMKs are supported and where audit logs are stored.
   • Validate retention windows, access controls, and integration with your SIEM.
5. Backup, DR and recovery testing
   • Test SyncIQ replication, CloudPools tiering, and backup/restore flows.
   • Measure RTO/RPO for key datasets and validate SLAs with Dell.
6. Cost modeling
   • Estimate storage consumption, snapshot frequency costs, CloudPools archive egress/ingress, and network egress for compute bursts.
   • Compare Marketplace billing to traditional Dell contracting for equivalent feature sets.
7. Legal and procurement
   • Obtain explicit service descriptions, capacity limits, maintenance windows, and data‑portability requirements in the contract.
   • Include audit rights and clarity on where data and logs physically reside.

---

Strengths and strategic value​

• Familiar enterprise data services: For organizations already using PowerScale on‑premises, the managed path avoids costly app rewrites and preserves operational semantics that many legacy apps require.
• Faster time to experiment: Azure Portal provisioning and Marketplace billing shorten procurement loops, enabling rapid PoCs for AI/ML and media workloads.
• Hybrid capabilities: CloudPools and SyncIQ let teams stage migrations, archive cold data seamlessly to Blob, and run hybrid DR/playbooks that span on‑prem and cloud.
• Purpose‑built performance: The NVRAM‑enabled SKUs represent a thoughtful engineering effort to lower latency and increase throughput for parallel workloads — a real differentiator if the claimed gains hold for your workload.

---

Risks, caveats and areas that need extra scrutiny​

• Unverified capacity claims: The 8.4 PB single‑namespace figure circulating in some press coverage has not been consistently documented in Dell’s public product pages for the managed edition; treat it as unverified until Dell confirms in writing. Use the 5.6 PiB guidance only for customer‑managed Azure planning unless Dell provides explicit managed‑service quotas.
• Vendor benchmarking vs real workloads: Performance multipliers quoted by vendors rarely translate directly to every workload. Validate throughput and concurrency under real‑world stress rather than relying on marketing numbers.
• Managed control plane tradeoffs: Moving to a Dell‑managed service gives up some deep customization and control over network topology and lifecycle. Ensure your compliance, eDiscovery, and forensic requirements are supported under the managed model before migrating regulated data.
• Cost complexity: Marketplace billing can be more convenient but introduces different cost levers (metered usage, archive egress, snapshot frequency). Model these carefully against long‑term on‑prem or customer‑managed cloud options.

---

Recommended adoption path for production migration​

• Stage 1 — Non‑critical PoC: Use the Azure‑native preview to validate integration with Azure AI compute, measure throughput with representative datasets, and test CloudPools behavior. Keep production data off the preview while you validate SLAs and security posture.
• Stage 2 — Hybrid pilot: Run a dual model with a customer‑managed cluster and a Dell‑managed namespace connected with SyncIQ. Validate failover, recovery, and replication latencies. Test real backup/restore and immutable copy workflows.
• Stage 3 — Contractual guarantees: Before migrating production datasets, secure written capacity/throughput limits, maintenance windows, data residency commitments, CMK support, and incident escalation SLAs from Dell. Draft a clear exit and data‑export plan.
• Stage 4 — Production migration with controls: Migrate in waves using CloudPools and SyncIQ, instrumenting performance and cost telemetry at each stage. Maintain runbooks for recovery and validate them with scheduled drills.

---

Final assessment​

Dell PowerScale’s move into Azure as a Dell‑managed, Azure‑native offering is a pragmatic answer to a real market need: the desire to run legacy, throughput‑intensive file workloads in the cloud without ripping and replacing storage semantics. The offering’s greatest strengths are its preservation of OneFS functionality, the operational convenience of Marketplace consumption, and the hybrid continuity features that support staged migrations and DR.
That said, the managed model introduces important procurement, security, and contractual considerations. Key capacity figures and headline performance claims should be validated with PoCs and secured contractually. Security‑sensitive teams must insist on clarity about key management, telemetry residency, and forensic access. Cost models should explicitly account for CloudPools archival behavior, snapshot cadence, and network egress during burst compute.
For organizations balancing fast adoption of Azure AI and the need to preserve enterprise data services, Dell’s Azure‑native PowerScale preview is worth trialing — but it should be treated as the start of a measured migration program, not a turnkey cure. Run instrumented pilots, obtain contractual guarantees, and build an exit plan before moving mission‑critical data onto the managed service.

---

The public preview changes the storage conversation in Azure: it makes enterprise file semantics a first‑class citizen in the portal, but the operational and commercial tradeoffs require rigorous, methodical validation before production adoption.
