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:
Mount ISO via CIMC
Install to RAID or SAN LUN
Configure management IP
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.
Performance comparison: VMware vs Proxmox on UCS
| Feature | VMware | Proxmox VE 9 |
|---|---|---|
| CPU performance | Equal | Equal |
| Storage performance | Equal | Equal |
| Live migration | Yes | Yes |
| HA | Licensed | Included |
| Backup | Separate product | Built-in |
| Licensing cost | High | Very low |
| Vendor lock-in | Yes | No |
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.
