EXPECT DOUBLE DISK FAILURES WITH ATA DRIVES – Dave Hitz – NetApp Founder
After reading Daves’ blog you have to wonder if NetApp keeps any of their critical accounting data or sales data on ATA drives. Dave goes on to say – Bottom line, using ATA drives without double protecting RAID is questionable. As drives grow, I suspect that it will become a requirement even for Fibre Channel drives.
Perhaps Dave is suggesting that the best protection against a poor implementation by the manufacturer of the storage subsystems and drives is to waste storage space. I guess that makes sense for the storage companies, because to protect yourself you need to waste storage space which means they sell more storage. But according to their sales and marketing campaigns their systems are extremely reliable. So why is Dave Hitz suggesting that customers buy more protection against disk failure?
Either their complete systems are reliable out of the box or they are not. Don’t worry though, Zerowait knows how to make NetApp systems reliable. Zerowait provides affordable alternatives to NetApp for Service, Support and Upgrades.
