Sangfor HCI, VMware and Nutanix: Where Do They Differ?

When VMware's licensing model changed, many organisations started reassessing their virtualisation platform at renewal time. The clearest difference between Sangfor HCI and VMware or Nutanix is that storage, networking and security come on the same platform without extra licences, along with more flexible licensing options. In this post we put the three platforms side by side and explain what to ask before deciding and how to run a sound POC.

Why did the search for alternatives begin?

After Broadcom acquired VMware, perpetual licences were discontinued and products were moved into bundled subscriptions. Many organisations saw their costs rise significantly at renewal and realised they were also paying for components they did not use.

Gartner also published a selection guide for VMware alternatives during this period and listed Sangfor among the sample vendors. In this post we compare Sangfor HCI with the two platforms it is most often measured against: VMware vSphere and Nutanix.

Side-by-side comparison

The Sangfor assessments in the table are largely based on the vendor's own comparison material; licensing details vary by version and region. Always confirm current bundle contents in writing at the quotation stage.

Five key differences of Sangfor

1. Five layers in one package

Sangfor delivers compute, storage, networking, security and management on one platform. With VMware, the same scope requires adding vSAN, NSX and a separate security product alongside vSphere. Each additional product means a separate licence, separate expertise and a separate support contact.

2. Flexible licensing

Sangfor is licensed per CPU socket and, depending on the region, also offers a perpetual licence option. This matters for organisations that prefer a one-off investment to spreading costs over years, while the subscription option remains open for those who want it.

3. Built-in security

Micro-segmentation, a virtual firewall, WAF and IPS are part of the platform. Traffic between virtual machines (east-west traffic) can be inspected without an additional product, which makes it harder for ransomware to spread between servers.

4. Freedom of hardware and storage

Sangfor can be installed on common x86 servers and can work with existing FC/iSCSI storage, so you do not have to replace hardware to migrate. Nutanix, by contrast, is limited to a specific certified vendor list.

5. Easy migration and Veeam support

Sangfor's migration tool copies from vCenter agentlessly and incrementally, bringing downtime down to the order of minutes. With the official Sangfor aSV plug-in that ships with Veeam Backup & Replication 13.1, existing backup processes also stay the same (Sangfor HCI 6.11.3 or later).

What to consider before deciding

Every platform has strengths and weaknesses. For the right decision, these points also need to be weighed:

• Ecosystem: VMware's third-party product and integration ecosystem is still the broadest. Check in advance whether the specific tools you use (monitoring, automation, application agents) support Sangfor.
• Edition and licence scope: Some advanced features (such as network virtualisation or QoS) come with specific licence editions. Make sure the features you need are included at the quotation stage.
• Team skills: The interface is simple, but it is still a new platform. Short training and a good implementation partner speed up the move.
• Independent validation: Vendors' TCO savings figures usually rely on their own calculations. The soundest approach is a POC on your own workloads.

How to run a sound POC

A comparison table is a starting point; the decision comes from results measured on your own workloads. Five steps make a POC meaningful:

• Choose representative workloads: Not the easiest virtual machines, but those that represent your real load profile, such as a database, a file server and a business application.
• Write success criteria in advance: Set acceptance thresholds for latency, IOPS, migration downtime and restore time before the POC begins.
• Try the migration: Move at least one virtual machine from vCenter with the agentless tool and measure the real downtime.
• Restore from backup: Take a backup with the Veeam plug-in and perform both full-VM and file-level restores.
• Calculate total cost over three and five years: Put licences, hardware, support and additional security products in the same table; do not look only at the first year's quote.

Three common migration mistakes

Squeezing the migration into the licence renewal date

When the decision is made a few weeks before the VMware renewal, the migration is rushed and the pilot phase is skipped. A realistic move needs months for evaluation, POC, pilot and migration waves. Organisations that know their renewal date start evaluating at least two quarters ahead, or plan a short bridge renewal from the outset.

Leaving backup and monitoring until the end

If it turns out after the virtual machines have moved that backup jobs and monitoring agents do not work on the new platform, the organisation is left unprotected for days. The Veeam plug-in, monitoring integration and alert rules should be ready BEFORE the first migration wave.

Writing security rules afterwards

Micro-segmentation is one of Sangfor's strongest points, but if it is written after migration, every existing connection has to be justified one by one and the project often ends with an "allow everything" rule. Mapping application dependencies before migration makes the security gain real.

Conclusion

With storage, networking and security in one package, a flexible licensing model and the ability to reuse existing hardware, Sangfor HCI is a strong alternative, especially for organisations reassessing their VMware licensing costs. With official Veeam support, a major obstacle to migration has also been removed. To plan a POC on your own workloads, get in touch with ATEON's specialists.
