Do you all over sell a host? Do hosts only house the same plans?

Interested in how oversold (if at all) a host can get. For example if a host only had 1 gig of ram it could only have 4 256 sized accounts on it correct? (yes, I realize there needs to be some extra ram for the parent OS)? Also, do hosts share plans. So will one host only have 256 meg plans or could there be a mixture of plans on that host? The reason I ask is it seems the bigger the plan the less busy the host would be if that is the case. Lastly, is your file system local or over a SAN / NAS?

Hi,

We do not oversell plans based on memory. You are correct we reserve a small amount of the parent OS (Hypervisor) and the rest of the memory is divided amongst the virtual servers.

Our algorithm places smaller virtual machines together, and larger ones together as well. This means you are also correct that the larger the server that you purchase the less busy the entire system is because there are less users, so you get even better performance.

We do not use a SAN/NAS for primary storage, we use it for backups and snapshots. All virtual machines run from local storage in production providing the best possible performance and stability to our users.
