Assessment & architecture
Evaluate the existing estate for virtualisation opportunities, assess readiness, then design an architecture aligned to your business goals rather than a vendor template.
VMware · Hyper-V · KVM · SAN & NAS
Virtualisation and storage
Consolidate infrastructure and cut the complexity and cost of hardware-based environments — with the storage underneath administered as deliberately as the hypervisor above it.
Virtualisation services
Consolidate the estate, cut the hardware bill
Virtualisation reduces the complexity and cost of traditional hardware-based environments — but only when it is sized, configured and maintained properly. That is the whole engagement.
Build
Installation & configuration
Set up hypervisors, configure virtual machines and integrate the platform into your existing environment without disturbing what is already running.
Right-sized
Capacity planning
Analyse resource utilisation and model future growth, so you buy the capacity you will need rather than the capacity you happened to have.
Minimal downtime
Migration & upgrades
Move from older VMware or another hypervisor onto current versions, and keep up with releases — planned and executed to minimise downtime and disruption.
Audited
Performance & health checks
Find and resolve bottlenecks, audit the health of the environment, and remediate what the audit turns up rather than filing it.
Ongoing
Support & patching
Ongoing technical support to troubleshoot and optimise, with patch management keeping hypervisors current for security and performance.
Storage administration
The storage half, which usually gets forgotten
Virtual machines are only as fast and as safe as the storage beneath them. We administer the array as deliberately as the hypervisor.
- Configuration and provisioning across enterprise arrays
- Performance tuning where latency is the real cause of a slow application
- Patching, firmware and controlled upgrades
- Replication between sites for disaster recovery
- Capacity monitoring, so you are not surprised by a full volume on a Friday
- Backup platform administration across Veeam and Commvault
- Troubleshooting FC, iSCSI, NFS and CIFS connectivity problems
Platforms
Hypervisors and arrays we work across
Flexibility without compromise — the platform is chosen on merit and licensing position, not because it is the one we happen to resell.

- VMware vSphere & ESXi
- Microsoft Hyper-V
- Oracle Linux KVM
- Citrix
Storage arrays
- NetApp
- Dell EMC
- HPE
- Hitachi
- IBM
- Oracle Database Appliance
Protocols & backup
- Fibre Channel & iSCSI

- Commvault
- SAN & NAS
Why Onsys
Three platforms, no favourites
VMware
A seamless transition to a virtualised environment that optimises your resources and improves operational agility — from hypervisor build through to ongoing health.
KVM
Flexibility without compromise. Oracle Linux KVM delivers cost-effective, adaptable virtualisation, which matters most when licence cost is the constraint.
Hyper-V
Microsoft Hyper-V for scalability and reliability, and the obvious choice where your estate and licensing are already Microsoft-centric.
Paying for hardware you no longer need?
A virtualisation assessment tells you what can be consolidated, what it would save and what the migration would involve. Book a free scoping call to start.

FAQ
Common questions
Hourly work is $150 per hour with a four-hour minimum, GST exclusive. Defined projects such as a hypervisor migration or array replacement are quoted as a fixed price with milestone payments, and ongoing support is included in managed IT plans from $4,500 per month.
VMware vSphere and ESXi, Microsoft Hyper-V, Oracle Linux KVM and Citrix. We are not tied to one — the recommendation follows your workloads and your licensing position rather than a reseller relationship.
Yes. Migration planning and execution from older VMware versions or another hypervisor onto current releases is a standard engagement, planned to minimise downtime with a tested rollback path.
NetApp, Dell EMC, HPE, Hitachi, IBM and Oracle Database Appliance, across Fibre Channel, iSCSI, NFS and CIFS, plus backup platforms including Veeam and Commvault.
Usually storage, and often latency rather than capacity. A performance analysis looks at both layers together, because tuning the hypervisor while the array is the bottleneck wastes the engagement.
Yes, when it is sized properly. Consolidation reduces physical hardware, power and licence counts together. A virtualisation assessment models what can be consolidated and what it would save before you commit to the work.
Yes. Health checks audit the environment, identify configuration drift and performance bottlenecks, and include remediation — so findings are actually fixed rather than handed over as a report.
Yes. Storage replication between sites for disaster recovery is part of the storage administration engagement, and pairs with the database-level DR work on our upgrades, migrations and DR page.
