It sounds as if for a requirement of N systems they have N+3. This redundancy criteria becomes more cost effective for larger N.

Personally I suspect that the statement is a classic 'snake-oil' one. It is an effort to seem impressive with lots of bits of information that the customer really has no need to know. What the customer really wants is for the system to work, and have maximum uptime.

HTH:)

pjedmond,

noted, do you mean my N+3 is that they have 3 fail over systems? if one fails there are two more to handle?
