Overall Satisfaction with Scale Computing HC3

Our HC3 implementation is a 3-unit cluster servicing 31 active virtual machines of varying architecture (Windows Server 2012 R2>Server 2019, and custom Linux distributions). It has provided nearly 100% uptime servicing of the VMs excluding severe power outages, and has eliminated the need for 8 former virtual host servers.
  • The cluster uptime is exceptional.
  • Performance is very good.
  • There is a solid web based configuration interface.
  • Modern SSO Authentication with MFA.
  • VM Auto-start controls are missing.
We have only had 1 issue, and it was resolved within 3 hours, with replacement hardware sent next business day.
  • We've eliminated multiple power intensive servers by amalgamating the workloads on to HC3.
  • The support agreement gives peace of mind against downtime.
  • Our server drive stock is gathering dust as we no longer need to worry about replacing drives and having stock on hand ourselves.
Our previous infrastructure was either IBM servers or custom built servers as hypervisors that weren't clustered. It meant downtime. TCO is about the same, but the improved uptime is dramatic.
It works very well in an education environment. It is well suited for databases, voicemail systems, mail filtering, domain controller VMs, DHCP VMs, web server VMs, building management system VMs, federated services VMs. I would say the only time we've seen a less appropriate instance would be extremely RAM intensive VMs, as the system ideally reserves 1/3 RAM to maintain its system redundancy against failure, so high RAM workloads cost 1/3 more in essence.

HC3 is very stable and highly scalable, however it does have 2 small issues: 1) the interface poorly delineates where you available RAM utilization will exceed the redundancy threshold, and 2) the interface has a small issue with the search field auto-populating usernames to it because of the field name. Neither are significant issues, but the intent is that gives you any idea of how stellar the product has been. That is all I can find to speak to, to not be a 10. You should get a good idea of how strongly positive I am towards the system.
We had 1 situation where a drive failed in a very unusual way, and the Scale system wouldn't let go of or allow us to replace the drive safely via our interface. Scale worked on the problem and crossshipped the replacement drive in one sequence. There was no delay. Scale understood the requirement of stability and uptime and made sure we stayed online. We have had zero downtime, apart from plant power failures which has nothing to do with Scale.
