This is all true - for what it's worth, the closest you'll come to cheap is low-end iSCSI storage from Dell/Equalogic or Dell/EMC or perhaps one of the really low-end NetApps, or look at HP/LeftHand Networks. Don't waste your money on a SAN.

If you use RAC either for HA or for scaling, you are in regions where CHEAP will not fit. So why not save the (little) money for a non-RAC, but rock solid solution? What's your goal behind the idea? (I don't want to offend you, I just have to fight the 'cheak' ideas of my management too often) regards, Martin -- Martin Berger http://berx.at/ I am planning a cheap RAC solution based on Red hat Enterprise 4 Linux (or oracle unbreakable Linux) . I get some hints from Jeff Hunter's storage solution, but i am not sure if it a stable one, and also the performance? Do anyone else implement such kind of "cheap" RAC setup with a very nice storage solution? What is your concern while you choose it ?
