Hypergrid Business has an article up about how OSGrid has left RAID MySQL behind to go with FSAssets, a high availability system of data storage.
It is all kind of geeky. If you are into that stuff, see HB’s article: Avination helps save OSgrid, donates cluster storage solution.
For the none geek, RAID and FSAssets are different ways of preparing for hardware failure and safely storing data. RAID stands for Redundant Arrays of Inexpensive/Independent Drives. The idea is if you have two hard drives with the second being a copy of the first, you’ll still have a good copy if one drive dies. It gets way more complicated as speed is another facet of RAID. But, two drives being safer than one is the base idea.
Unfortunately there are failures that can take down all the drives or corrupt all the data. I’ve been there and done that. I don’t use RAID as my sole backup plan any more. Neither does OSGrid, apparently.
I’m not that up on what FSAsset is. So, I won’t try to explain much of it. Suffice to say it is more like using multiple computers with multiple drives rather than using multiple disk drives in a single computer.
