I did something odd, you're right. I'm sorry. ---- pinky 42% dc 60 60 * 24 * 30 * p 2592000 seconds/30 day month. 0.00001 * p 25.92000 ---- My point is still that five 9's is usually unnecessary and is about always really expensive and unreasonable. It's a lovely marketing phrase that should be taken like we take "windows is secure, stable, solid and ready to run your enterprise." Giggle a bit and set expectations that a 60 minute down time every couple months is just fine along with regular maintenance intervals. Have a spare machine ready to hook up to your RAID unit. A failure, identified after 5 minutes, means that you can spend 15 (tops) minutes plugging it into a cold spare. Cost? Pretty low. Cost compared to acquiring, setting up, and running an HA pair over a couple years? About 1% :)
