What kind of hardware redundancy is in place? Are all the ssd’s local storage or is it on a nas\san storage? Are these rackmount servers or blades? What kind of density is per host? What kind of guarantee do I get that the host is not going to be overloaded/oversold?

All servers run hardware RAID with different RAID levels but in each case it requires multiple drive failures at the same time for any data loss to occur. In most cases when there is an issue usually a system becomes degraded and starts to exhibit anomalous behavior, at which point we determine that it is no longer healthy to keep it in production and open a maintenance window with customers and migrate their virtual machines to a new hypervisor. <br> <br>In an emergency case we may move the virtual machine without much prior notice if we believe it is imperative to clear out the hypervisor sooner. <br> <br>In regards to data storage we highly recommend to use several different levels for your backups. That includes enabling the internal backups that we provide, taking the occasional snapshot, and also implementing some sort of off-site backup yourself where you focus on moving the content and data that is the most essential to you.
The SSD’s are local storage and they use KVM which generally prevents RAM from being oversold. CPU is assigned per Droplet and from my experience, you’re allow to use the full CPU Core allocation. <br> <br>We’ve frequently fully utilized 2-8 CPU Cores (depending on the Droplet) without any issues and speeds have been great. <br> <br> <br>I can’t really comment on density, though they have done a great job making sure that other clients don’t affect our service. We’ve had one issue with a “noisy neighbor” though it was handled extremely fast and since then we’ve not had any issues with other clients affecting our service or our clients.
Local storage means NO HA. what happened in case of failure of one host. <br>What is RAID Level 1,5,6 or 10? Data is very important, not sure in case of failure it is replicated on other storage or not…
