Moving from VMware to Proxmox without replacing Cisco UCS hardware

Many companies in Dubai and across the UAE invested heavily in Cisco UCS servers running VMware. After recent licensing changes, customers started asking: Can we keep Cisco UCS and migrate away from VMware?

Yes — and we’ve done it multiple times using Proxmox VE 9, an enterprise virtualization platform and VMware alternative.

This article explains our real production experience deploying Proxmox on Cisco UCS infrastructure in UAE datacenters.


Why Cisco UCS works perfectly with Proxmox

Cisco UCS is enterprise x86 hardware.
Proxmox VE 9 is based on Linux KVM virtualization.

That means:

No proprietary hypervisor dependency.
No vendor lock-in.
No UCS-specific plugin required.

If your UCS runs VMware — it will run Proxmox.


Hardware platforms we migrated in UAE environments

We have deployed Proxmox VE clusters on:

  • Cisco UCS C-Series rack servers

  • Cisco UCS B-Series blade chassis

  • Boot-from-SAN UCS environments

  • Hyper-converged Ceph clusters

  • 10G / 25G Fabric Interconnect networking

All migrations were completed without replacing servers — only the hypervisor changed.


Installation on Cisco UCS (10 minute deployment)

Typical VMware installations on enterprise hardware often require vendor drivers and compatibility bundles.

Proxmox installation process:

  1. Mount ISO via CIMC

  2. Install to RAID or SAN LUN

  3. Configure management IP

  4. Access web interface

That’s it.

This simplicity is why many organizations in Dubai now consider Proxmox a serious VMware replacement solution.


Networking with Cisco Fabric Interconnects

One major concern customers have:

Will Proxmox support UCS networking architecture?

Yes.

Cisco UCS presents standard Ethernet adapters — Linux handles them natively.

Our production design:

UCS configuration

  • vNIC templates

  • VLAN trunking

  • Jumbo frames (MTU 9000)

Proxmox configuration

  • Linux bridges

  • LACP bonding

  • VLAN-aware bridges

Live migration and HA traffic run without packet loss.


Storage architectures supported

We successfully deployed the following enterprise storage models:

Local RAID (traditional virtualization)

Performance equal to VMware.

SAN (iSCSI / Fibre Channel)

Multipath works natively — no vendor plugins required.

Hyper-converged Ceph (recommended)

This is where Proxmox becomes powerful.

UCS nodes become both compute and storage:

  • High availability storage

  • No SAN dependency

  • Lower cost infrastructure

Ideal for organizations replacing VMware vSAN in UAE.


High Availability testing

We simulated real failures:

  • Host crash

  • Network outage

  • Disk failure

Proxmox HA automatically restarted virtual machines on surviving nodes.

Unlike VMware — HA is included, not licensed separately.

Operational advantages after migration

Organizations in UAE noticed immediate improvements:

  • No VMware licensing audits

  • Faster VM provisioning

  • Built-in backup server integration

  • Native Linux tooling

  • Easier clustering

  • Lower yearly costs

 


Production stability

We now run on Cisco UCS + Proxmox clusters:

  • Windows servers

  • Linux servers

  • Databases

  • Containers

  • Backup infrastructure

Stability has matched or exceeded VMware environments.


Who should consider Proxmox on Cisco UCS

This architecture is ideal for companies in Dubai & UAE that want to:

  • Exit VMware after Broadcom changes

  • Keep existing Cisco UCS hardware

  • Build hyper-converged infrastructure

  • Reduce datacenter licensing costs

  • Avoid vendor lock-in

 


Our conclusion

Migrating Cisco UCS from VMware to Proxmox VE 9 does not require replacing infrastructure.

Only the hypervisor changes — everything else continues working.

This makes Proxmox one of the most practical VMware alternatives available today.
