Kernel-based Virtual Machine (KVM) vs. Scale Computing Platform

KVM is the best solution in the case you need to test and turn up any virtual environment with limited vCPU/RAM resources. The obvious area of its use is a network environment when we want to avoid being tied to one type of hardware/vendor and being able to swap from one instance to another with no downtimes. The use of a vSwitch (that supports VLAN tagging) is a significant bonus for network engineers that some other hypervisors do not provide.

Scale is best suited to environments that do not have excessive external or proprietary peripherals. Integrating with tape drive backups or robot tape libraries can be problematic. The most effective use of Scale systems is for companies running multiple instances of the same operating system. The hypervisor's code/file-sharing nature does an excellent job managing new instances while keeping the increase in storage to a minimum.

• KVM is really good at providing fast and reliable virtualization for Linux guests
• Since KVM is a kernel module, every VM is a Linux process which can be managed by Linux system tools
• KVM integrates very well with the management framework libvirt, which is why KVM can be integrated in automation tools as well

• Simplicity - I do not have to create storage buckets or micromanage anything.
• Efficiency - Lower power use since moving to a hyperconverged environment.
• Scalability - Adding additional hardware is easy, and increasing things like the amount of RAM or number of cores is easy.

• Complex networking
• GPU processing is not fully supported
• It's hard to set up without support tools

• Dedicated Lights-Out Solution for low-end systems
• Ability to replace smaller storage drives with larger ones, rather than requiring the addition of an entire node for storage increases
• Different UI views for VMs: ability to minimize certain groups and have that persist through log-ins

Since I have had no issues with downtime; easier management of my cluster and the ability to lower the number of devices in my Infrastructure, I will gladly renew my support contract with Scale Computing HC3 and upgrade my equipment with them when it comes time for it.

Everything you need to do is point-and-click easy. If you are the kind of admin who wants to edit every config file and endlessly customize your environment, then Scale may not be for you. On the other hand, if you just want it to work really well, and do what they told you it will do, then Scale is the ideal system.

Never had an outage or an error. Once a hard drive failed, but Scale kept on working flawlessly without interruption.

Performance has been just as outstanding as reliability. I have never experienced delays in any aspect of usage.

They are very knowledgeable about their own products and hardware addressing my concerns or issues very quickly and on the first contact. Calls concerning VMware migrations and Acronis backup took a little more time for more complicated issues, but the Scale Computing Platform techs were diligent to stay on top of issues until they were resolved. Most of my issues have been with the initial setup/migration.

I did not do in-person training.

Because Scale is so simple, the training is just as quick and easy.

The implementation was very easy. We had Scale support on standby and they were ready and eager to help if needed. The process went so fast the employees in the organization did not even know it was done.

Kernel-based Virtual Machine is an open-source and free solution, compared to Virtualbox which is a product from Oracle.

We previously used Microsoft Hyper V and VMWare and, before that, a room for single-purpose servers. My satisfaction with Scale is because it is a more straightforward product to install and use; it has incredible speed and reliability. In the past, getting support from Microsoft was labor intensive, and with VMWare, there was a language accent barrier.

HC3 is one of the best products I have purchased for our district. It is unbelievably reliable to the point that they shoot themselves in the foot on support contracts.

• KVM just works and gets out of the way
• KVM is working great with other open-source technologies like QEMU and libvirt

• With the high cost of the leading competitor the savings starts day one and saves every year after.
• Scale can be administered by a tier one technician so cost of labor is reduced.
• If there is a problem like a cyber attack, the savings kick in with the least amount of downtime.
