When purchasing a Storinator, we offer two options as the power supply for your unit: single and redundant.
Single: power supplies work the same as in a standard desktop computer. They power the different components inside of your system, including the drives and motherboard. Single power supplies are the default option for all Storinators currently offered, with the exception of the Storinator XL60. When using a single power supply, if a failure were to occur, your Storinator would lose power and go offline.
Redundant : power supplies offer increased protection against failures. In the case of your primary power supply failing, the secondary supply would immediately engage in order to prevent your system from going offline. Redundant power supplies are perfect for satisfying availability requirements by removing the power supply as a single point of failure.
In addition, all Storinators come by default with replicated boot drives, configured in a RAID 1. This ensures if one boot drive fails, your server will stay in operation. You have the ability to hot swap faulty boot drives.
