    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.

    As a nonprofit, we needed a virtualization platform that was reliable, cost effective, and simple to administer. StarWind HyperConverged Appliance checked all the boxes for us. We went with their refurbished models to lower the cost, and they've been rock solid. We were able to simplify our environment and the platform has been so reliable that I really don't have to think about it. This has been great for me as the sole sysadmin. There are a lot of pieces to manage, and StarWind HyperConverged Appliance have allowed me to focus less on the platform and more on the VM's themselves and the other pieces of our network environment. I think as long as you get the "right size" of StarWind HyperConverged Appliance that this platform could work well for many organizations.

    Pros
    Red Hat
    • 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

    • It is extremely easy to set up, it comes with most options pre-configured for you. But the support group will walk through your entire setup and migration.
    • It is monitored by StarWind 24x7. Instead of issues being reactive with the monitoring I'm hoping things will be more proactive.
    • The performance has been outstanding. I think disk was our main limiting factor with our hold hardware.

    Cons
    Red Hat
    • KVM itself doesn't ship with a management interface
    • KVM itself is a bit complicated to handle
    • KVM needs Qemu to virtualize Windows guests

    • Support team has slight accent but is not too difficult to understand.
    • Emphasis on security can be improved. Things like default passwords were not changed initially until requested.
    • Can't really think of much else...If I had to split hairs...on reboots sometimes it took a while to sync with the other node. Max was 30 minutes, but 99% of the time it's 3-4 minutes.

    The hardware appliance convinced me. It is also good to use as a product in the box.Experience of the speed and security of the storage and the data on the storage is important.Installation is relatively easy and support is supportive. You are not left alone.Therefore a clear recommendation

    Usability
    Red Hat
    It does the job and stays out of the way. The specifics of usability relies on the implementation, but with things like Icarus and libvirt, things are standardizing nicely.

    Overall, the appliance is versatile. It covers the adaptation to all current hypervisors and can be addressed via different protocols. This prepares you for a wide range of uses.Rack mounting is also well thought out. And last but not least, apart from the technical performance, it is also an eye-catcher.

    Working with the
    support team has been great. Connecting with somebody during and after business
    hours has been smooth, and they have always been responsive and professional. I don't have to wait very long to hear back from them when either sending out an email with a question or inquiry or when calling after business hours when we had to shutdown and bring back up the servers due to hurricanes here in Florida.

    Literally, while writing this review, I just received an email from starwind saying my VSAN version was out of date due to a recent update coming out and they offered to help me install it. Its just amazing how "on top of it" support is. They'll monitor downtime, reboots, version issues, even the bios firmware on the Dell servers... I can't imagine using any other vendor, they just do it all, and they do it well.

    The old saying: Preparation is everything.It should be ensured in advance that the operating system is up-to-date and therefore suitable for the appliance.The recommended network adapters should also be used in the network and the firewall rules adjusted.If this is planned in advance and everything is prepared, then the installation can be carried out relatively quickly.The manuals and the StarWind website are also a very good help.

    It is a very reliable solution that can be used for x86 architecture virtualization with low overhead. It is a free and open source software. Easy to use withOpenStack.

    Scale was a proprietary SAN software/hardware and outrageously high priced. The StarWind HyperConverged Appliance was just Dell servers with VMWare ESXi Hypervisor installed running two Windows Servers virtual machines where the StarWind SAN software is installed on. The only thing that was proprietary for StarWind was the StarWind SAN software

    Return on Investment
    Red Hat
    • Fast provisioning of new servers.
    • Huge drop of the cost of servers compared to bare metal.
    • Easy upgrades of resources, sometimes now even requiring a server restart.

    • Our CIS software has some poorly optimized SQL logic. Our old Failover Cluster w/ a VNXe3200 SAN would take up to 7 seconds to pull a customer's records up. It now takes only 1-2 seconds. Our front office has been much more pleasant since their install.
    • I would only rarely have to interact with our blade switches and VNXe SAN, so I wouldn't necessarily retain the knowledge of how to configure them. Each time I'd need to make a change, I'd have to refer back to my documentation. That's no longer an issue I have to deal with.
    • The rack footprint for our cluster went from 14U to 4U, and we were able to achieve it with much less network cabling and with lowered power requirements.
