Equipment Redundancy
| List Options | Option Definition | Unit of Measure | |
|---|---|---|---|
| 2N | 2N means two times the capacity required for operation. Two units of equal size, capabilities, and capacity. | None | |
| Greater than 2N | Greater than 2N means more than two times the capacity required for operation. | None | |
| Is available | Redundancy is available for a given piece of equipment | None | |
| Is not available | Redundancy is not available for a given piece of equipment | None | |
| N | N is the amount of capacity needed to operate. There is no backup system so if the system fails, it fails and downtime is the ultimate result. This level is equivalent to "Is not available" | None | |
| None | None | None | |
| Not applicable | Not applicable | None | |
| Nplus1 | N+1 represents the amount required for operation plus a backup. It ensures system availability even in the event of a component failure. It is similar to the concept of a spare tire on your car. When you get a flat, you have the ability to swap out the flat with a spare tire. This simply means that you could survive one flat tire. | None | |
| Nplus2 | N+2 represents the amount required for operation plus two backups. For example, a car has four tires for operation. N+2 redundancy would require two spare tires. | None | |
| Other | Other | None | |
| Unknown | Unknown | None |
