Solution

Data Centre Solutions.

Enterprise infrastructure on proven architecture.

Validated reference architectures: FlashStack, HPE dHCI, Rubrik, HPE GreenLake. Designed, supplied and managed by Onel - as a capital purchase, or as a service on a monthly fee. One contract across the full stack.

Everything else in the organisation is sitting on top of this, which is why we build it on platforms the vendors have already tested together rather than assembling parts and hoping. When something does go wrong, that decision is the difference between one support call and three.

Most people arrive here via a referral. If that's you, here's who to call.

Reference architectures

Four validated platforms. One partner.

A validated reference architecture is a combination the vendors have engineered and tested as one thing, and will support as one thing. We deploy four of them. Which one depends on your workload and, just as often, on whether you want to own the hardware or rent it.

Delivered as a service

Disaster Recovery as a Service.

Most organisations have a disaster recovery position on paper and no budget line to build the second site it assumes. DRaaS removes the capital purchase: replication, a recovery platform, failover automation and the testing that proves it works, on a monthly fee over a three to five year term.

It is in production for Victorian councils, a TAFE and an independent school. The platform is the same one we would have designed as a capital project - the difference is who owns it and how you pay for it.

Commercials

Monthly fee, no capital purchase

Three to five year terms. Hardware, software, services and support in one line item. If the platform choice is still open, start with IT strategy consulting.

What it covers

Replication, failover, retention

Application-aware replication to a second site, automated failover and fallback, and disk-based retention. Also available on our managed private cloud platform.

Proof

Tested, not assumed

Scheduled DR exercises against documented recovery objectives. Bayside’s auditors called the result sector leading. Read the council case studies.

Data protection

SafeMode snapshots

Rubrik integration

Policy-driven backup

Pre-validated, jointly supported

Because it is a Cisco Validated Design, both vendors support the combined stack. That matters most on the day when the storage vendor and the compute vendor would otherwise be pointing at each other.

All-flash performance

Sub-millisecond latency and consistent performance at any scale: ideal for databases, VDI, ERP and latency-sensitive workloads.

Built-in ransomware protection

SafeMode snapshots cannot be deleted or altered, including by an administrator account. That is aimed squarely at ransomware, which now goes looking for the backups first.

Evergreen, no disruptive upgrades

Pure's Evergreen model upgrades arrays in-place, non-disruptively, for the life of the platform, no forklift upgrades, no migration projects.

Ideal for

→Mission-critical virtualised workloads with low-latency needs
→VDI and high-density virtual desktop environments
→ERP, CRM, business-critical application hosting
→One support contract across the full stack
→Environments requiring immutable storage

Reference architecture 02

HPE Disaggregated HCI (dHCI)

HPE dHCI delivers the simplicity of hyperconverged infrastructure without the compromise. Compute and storage scale independently on dedicated hardware. The operational benefits of HCI, with true enterprise flexibility.

Independent compute and storage scaling

Unlike traditional HCI where you scale both together, dHCI lets you add compute or storage independently, eliminating over-provisioning and wasted investment.

AI-driven predictive operations

HPE InfoSight analyses millions of data points across the global install base to predict and prevent issues before they affect your environment.

Simple HCI-like management

The operational experience feels like HCI: unified management, automated provisioning, simplified lifecycle ops, but without the rigid coupling.

Better economics at scale

Because compute and storage scale independently, you only buy what you need, avoiding the classic HCI trap of buying storage just to add more CPU.

GreenLake ready

Fully compatible with the HPE GreenLake consumption model, convert to as-a-service billing at any point.

Ideal for

→Organisations moving from traditional 3-tier to simpler platforms
→Environments with asymmetric compute vs storage growth
→Mixed workload environments needing flexible resource allocation
→Organisations already running HPE or Aruba infrastructure
→Teams wanting HCI simplicity without performance compromise

Immutable backups that ransomware can't touch

Rubrik backup data is immutable at the storage layer. Even if an attacker gains admin credentials, they cannot encrypt, delete or modify your backup data. Part of the wider IT security services picture.

AI-powered threat detection

Rubrik Radar monitors backup data for anomalies: unusual encryption, sudden data changes, suspicious file access, and alerts you before it's too late.

Fast, orchestrated recovery

Recover individual files, full VMs or entire application stacks in minutes, automated recovery runbooks execute complex recoveries without manual steps under pressure.

Protects everything: cloud, on-prem, SaaS

One platform protects VMs, physical servers, databases, NAS, Microsoft 365 and cloud workloads across AWS, Azure and GCP, single policy engine. Including workloads moved under our cloud migration services.

Compliance and data governance

Data classification discovers and tags sensitive data across your backups: supporting Privacy Act, Essential Eight, GDPR and sector-specific frameworks.

Ideal for

→Organisations that have experienced or are concerned about ransomware
→Regulated industries requiring defensible backup compliance evidence
→Mixed workloads across on-prem and cloud
→Microsoft 365 data protection
→Replacing legacy backup tools with a modern, secure alternative

Reference architecture 04

HPE GreenLake cloud economics, on your premises

HPE GreenLake brings the commercial model of public cloud (consumption billing, elastic capacity, no capital commitment) to infrastructure that runs in your own data centre. Pay for what you use. Scale as you grow.

No capital expenditure

Hardware is owned and installed by HPE at your site. You pay a monthly fee based on actual consumption, converting major CapEx into predictable OpEx.

Elastic capacity on demand

Buffer capacity is pre-installed and available to activate immediately. Scale up when you need it, no procurement cycles, no lead times.

Your site, your data

Infrastructure stays in your facility. For data sovereignty: government, healthcare, finance. GreenLake delivers cloud economics without moving data off-premises.

HPE manages hardware lifecycle

HPE handles refresh, warranty and end-of-life replacement, so the hardware stays in support without anyone on your side running a procurement round every few years.

Onel adds managed services on top

Onel layers 24/7 monitoring, patch management, incident response and capacity reporting on top of HPE GreenLake, a complete fully managed service.

Ideal for

→Eliminating large infrastructure CapEx cycles
→Government and regulated industries with sovereignty requirements
→Cloud-like flexibility without moving to public cloud
→Unpredictable growth that needs rapid capacity response
→Finance teams shifting IT spend from capital to operating

FlashStack, dHCI, Rubrik or GreenLake, how do you decide which one fits?

Three things drive it: workload profile (steady-state vs. variable), commercial model (capex vs. consumption), and operational fit with your team. FlashStack suits high-IO mixed workloads; dHCI fits compute-dense virtualisation; Rubrik anchors data protection; GreenLake covers consumption-based on-prem. We walk through the trade-offs in plain English before recommending.

Do we have to refresh everything at once, or can we phase it?

Phased refreshes are the norm. We start with the platform under most pressure - usually storage, backup or the firewall edge - and build a multi-year roadmap that lines up budget cycles with refresh cycles. No big-bang projects unless that's what you actually want.

Can you also support our existing kit, not just new builds?

Yes. We routinely take over support of existing data centre estates - HPE, Cisco, Dell, Pure, VMware, Hyper-V - and add monitoring, patching and 24/7 incident response. We don't require a refresh as a condition of taking on support.
