- ChuckMcM 15y agoExcellent article. Running LVM over raid 6 volumes is the 'standard' approach of many enterprise storage deployments. The 'magic' in a good RAID6 implementation is what it does when things go wrong, and lots of things do go wrong. The checksumming is great too. At some point you can dump the sheet metal on the 'pods', just build your own rack unit. If you look at the 'big iron' systems from NetApp, EMC, and others you will see they make one big enclosure then can install simpler systems within that enclosure. What this buys you is that you can distribute enclosure services into the big box and take it off the individual boxes. That gives you better cost efficiencies. And as you point out your system can run with fewer fans, so you can put a couple of largish three phase fans in the big enclosure (dead simple and very reliable) and use them to push the air through all the other boxes. (or pull it). Then add an android tablet for the 'door' of the enclosure that tells you drive status, etc and you're practically a player in the storage game :-)
