No, it's not a level of sunblock protection (as if the Sarge required such things - Sarge wears SPF 80,000 in the form of black tar on his face for protection). SPF, in the world that matters (not beaches and BBQs), means "Single Point of Failure."
Many storage companies are fond of saying they have no single point of failure on their equipment, but neglect to mention that often everything runs through one backplane (maybe with dual controllers). Everyone that thinks a backplane isn't a single point of failure needs to drop and give me 20! You're worthless and weak!
A backplane is just as likely to fail as a controller, meaning that if you have all controllers and storage going through a single backplane, you have SPF ZERO! You have a single point of failure!
The Sarge has one word for you: Cluster!! For high availability storage applications, you must cluster storage boxes for full redundancy. Not only will you impress your country club yuppie friends by dropping a word like "cluster," but you'll get processing power as well as storage.
Redundancy is important - that's why the Sarge has two weapons on his person at all times.
At ease!
