Ensures a robust, user-friendly virtualization platform with seamless VM management, efficient resource allocation and a strong community for support

Improvements are needed for the API. Currently, there are several features inaccessible through the API, necessitating the use of either the WebUI or the command line interface. While the command line interface suffices, it's apparent that efforts are underway to enhance this aspect. In future releases, one potential feature enhancement could be improved remote screen access, allowing users to connect to the screen of another machine more seamlessly. Additionally, integrating with Terraform or providing better support for Terraform workflows might be beneficial, as there seems to be some lacking in that area. There's a minor inconvenience where you have to switch the license file from the open-source community license to an enterprise license.

Extremely easy to learn and use for beginners

Some features go well with other tools like VMware, where making something on the fly or making some changes on the fly in the area of memory or something is possible. On the fly, you cannot do anything on Scale Computing HC3, though it is a very rarely needed area. Being able to make some changes on the fly is very risky, but even then, you see customers saying since it is an area that is not possible with Scale Computing HC3, it is better to go with some other tools. My company convinces our customers that opting for another solution is not required since a tool that allows us to make some changes on the fly can be very risky, and it is also not something that fits in according to certain policies or good practices.

"The affordability of the solution is the product's most valuable aspect."

"We can access the product from iPhone 7. It is stable and easy."

"You can easily migrate VMs between hosts."

"We had issues with this solution when it comes to resources. We have officially created four to five PMs and it just continues to make more resources even though they are delivered in the main post mode."

"The solution's most valuable feature is backups."

More Proxmox VE pros

"It gives the ease of management for a small IT department."

"The product's initial setup phase is too easy."

"The solution is scalable."

"The most valuable features are the appliance-type feel and that you don't need additional licenses as everything is built-in."

"I like that Scale Computing HCR is slimmed down and gives me the features I need and not features that I don't need."

"I rate Scale Computing support 10 out of 10. They're accessible and responsive."

"The initial setup is pretty straightforward."

"The most valuable feature of Scale Computing HC3 is if one of the devices fails, you won't even notice, the service maintains operation. The customers don't have to waste two, or three days on delays. Additionally, you do not have to waste time with recovery software, it is a lot easier."

More Scale Computing Platform pros

Cons

"I don't have enough experience to say what can be improved."

"It's one of those things for me to move things on to the cloud. It's not so easy. I am always on the laptop and have to monitor that because if you want to make strides; you need to stay online."

"Lacking in enterprise features."

"The facility of deployment is an area that needs to improve."

"There are some things that need to be done using the command-line interface, and these should be moved into the web-based interface."

"Its performance and support can be improved. Currently, there is a cost for support."

"Its user interface can be improved. In the version that I am using, not all functions can be performed by using the UI. There can be some improvement on that. I'm assuming that it has already been improved in the latest version."

"I can't speak to any improvements. It is not lacking features."

More Proxmox VE cons

"The product struggles to cope with bigger workloads. In the next release, I'd like some backup solutions to be added."

"The snapshot technology takes up 500 times more space compared to other solutions."

"On the fly, you cannot do anything on Scale Computing HC3, though it is a very rarely needed area."

"There could be an easier way to see which servers are on each node"

"The product could use a better control center."

"I would like bigger clusters with more than eight nodes."

"I've had so many issues with the sales team when I was looking to make some improvements, and improve the performance. They would create so many excuses to force me to buy new nodes all the time and not let me add more memory to each node."

"Scale HC3 improvements would involve literally fixing up the replication."

More Scale Computing Platform cons

Pricing and Cost Advice

"An excellent choice for budget sensitive operations."

"Proxmox VE is free of cost."

"The only thing you pay for is support and it is between $2,500 and $3,000 a year. It depends on the support plan you choose. Support is optional."

"Since Proxmox is open-source, it's freely available."

"I am not aware of the licensing cost, but there is a cost for support."

"Proxmox is free."

"There is an annual license to use Proxmox VE and it is approximately $90. There are not any additional costs."

"It's very cheap."

More Proxmox VE pricing and cost advice

"The product is worth the money, but I would not say it's very cheap or very expensive."

"I give the pricing a nine out of ten."

"I pay for Scale Computing HC3 and it includes customer service for one year. We paid for an additional year for customer service but that includes the updates and everything for the software. Additionally, the licensing is for Windows, which is the same for everybody."

"rate HC3's pricing a five out of ten since it is affordable."

Scale Computing HC3

Overview

Proxmox VE is a complete virtualization management solution for servers. It is a powerful open-source platform and supports two virtualization technologies - KVM (Kernel-based Virtual Machine) for virtual machines and LXC for containers. Proxmox VE has a central user interface that allows you to manage not only VMs and containers, but also storage resources, network configuration, and high availability for clusters. It is enterprise-ready and is valued for its scalability and maximum flexibility, enabling you to virtualize very demanding workloads. Proxmox VE makes it possible for you to easily install, manage, and monitor hyper-converged (HCI) data centers.

Proxmox VE Key Features

The Proxmox VE platform has many powerful features, including:

pen-source software, high-available clusters, command line, fencing, a web-based management interface, flexible storage options, REST API, live/online migration, storage replication stack, software defined storage, virtualized networking, backup and restore, two-factor authentication, role-based administration, and VM templates and clones.

Proxmox VE Benefits

Some of the biggest benefits of Proxmox VE are:

Central management: To manage all tasks of your virtual data center, you can use the central, web-based management interface.
Unique multi-master design: Proxmox VE allows you to carry out maintenance tasks cluster wide, from any node.
Minimize downtime: With the integrated live/online migration feature, you can move running virtual machines from one Proxmox VE cluster node to another, without any downtime or noticeable effect from the end-user side.
Granular access: Using Proxmox VE’s role-based permission management system helps you define granular access to all objects.
Multiple authentication sources: Proxmox VE supports multiple authentication sources, including Linux PAM, an integrated Proxmox VE authentication server, LDAP, Microsoft Active Directory, and OpenID Connect.
Several storage options: The Proxmox VE storage model is very flexible and the web interface allows you to add multiple storage types (LVM Group, iSCSI target, NFS Share, SMB/CIFS, Ceph RBD, Direct to iSCSI LUN, GlusterFS, CephFS).
Collaboration with Ceph: Proxmox VE fully integrates Ceph, giving you the ability to run and manage Ceph storage directly from any of your cluster nodes.
Scheduled backups: With Proxmox VE, backups can be scheduled so that they automatically run on specific days and times, for selectable nodes and guest systems.
IT infrastructure protection: Proxmox VE has a built-in firewall that works to protect your IT infrastructure. The firewall is completely customizable, allowing complex configurations via the GUI or CLI.
