Milo_Mindbender asks: "At home I've collected too much data to easily backup, so I've been thinking about RAID5 for a little extra data security. I multiboot my computers for both Linux and Windows so I really need a RAID solution that will make the data at least readable by both OS's. I don't think this can be done on a single machine (can it?) so I'm looking to put together a Linux home server with RAID5 serving both SAMBA and NFS. Aside from the usual questions (software/hardware RAID, types of disk to use...etc) because I live by myself in an apartment I have a few tricky requirements I hope the Slashdot crowd can help me with." How would you set up a RAID5 server to perform Samba/NFS sharing duties without it wasting a lot of wattage, while it idles?"I hate to waste electricity, so how can a Linux RAID5 server be setup to automatically spin down to the lowest possible standby power use, then spin back up when a computer accesses it? I don't have a basement, garage or other remote place to put the thing, so it needs to be quiet or at least not die a thermal death if I lock it in a closet. What's the sweet spot for choosing CPU type/speed, hardware/software RAID controller, motherboard and memory to make a home server? Since this is only going to be serving a few machines (and maybe doing router/gateway duty), I'm sure there's a point where adding more CPU horsepower doesn't improve performance much. Any suggestions on motherboards, cases or even complete systems that work particularly well for this kind of small headless home server?"
